> the once-responsive Oura has not yet replied to any of my inquiries, or committed to releasing the numbers
Illinois has a tight biometric-privacy law [1]. I’d bet Oura isn’t particularly careful about prohibiting e.g. a Texas police department querying the protected information of Illinois residents.
"In my previous blog, I revealed that Oura data is not end-to-end encrypted. That means that an Oura user's health data can be unscrambled at certain points as it travels from a person's ring, through their phone app, over the internet, and as it lands on Oura's servers."
Very strange -- it seems to be conflating end-to-end encryption with encryption-in-transit.
My understanding is that E2E encryption implies encryption in transit. The message is encrypted at the source and only decrypted at the destination, so it is encrypted everywhere in between.
The term has kind of degraded, because people started marketing that "end-to-end encryption" is the "right" answer.
Encryption in transit means that network intermediates can't read the data. The two endpoints of the network communication can.
E2E encryption is more context-sensitive, and its context mostly comes from messaging. It means that the data is encrypted and that operational intermediates cannot read it. So in the context of messaging, the servers that run the messaging system cannot read the messages. Or, for an email, only the sender and recipient, not any of the intermediate email servers.
There's a big difference -- you can't really control or predict your network intermediates, but you can in theory know the operational intermediates. Whether something is E2E encrypted often depends on what intermediates you bring in to scope.
For example:
> That means that an Oura user's health data can be unscrambled at certain points as it travels from a person's ring, through their phone app, over the internet, and as it lands on Oura's servers.
If the ring uses Bluetooth to sync the data to your phone and the phone syncs data to the Oura servers, but the data is in the clear on your phone, then by this definition, it is not E2E encrypted. However, that's a pretty reasonable setup, depending on how the data on the phone is stored.
I have to disagree. It's the same thing that happened to terms such as open source. It's perfectly clear what it means but marketers intentionally attempt to mislead people for the sake of their own bottom line.
> but the data is in the clear on your phone, then by this definition, it is not E2E encrypted.
False. E2EE is centered on a given user. So long as the phone would be viewed as "yours" (ie inside your personal security boundary) by a reasonable person then it is clear that the data is E2E encrypted.
As the sibling comment notes the common issue is providing a web interface. It isn't so simple to have a remote server dish up a nice UI with lots of convenient functions while only decrypting the data on the client side. It can certainly be done but it requires developers that know what they're doing and management willing to budget for it.
> If the ring uses Bluetooth to sync the data to your phone and the phone syncs data to the Oura servers, but the data is in the clear on your phone, then by this definition, it is not E2E encrypted.
Yet another angle would be that both the phone and the ring are in one's material possession, whereas the cloud is someone else's computer, and to display a nice web UI it has to have the data unencrypted over there.
In that case, the cloud is the potentially untrusted intermediate between the data and one's eyeballs.
All of these are equally valid, it all depends on what is your threat model.
Does encryption at rest actually do much? The percentage of attacks that were perpetrated by people getting physical access to a drive must approach zero.
I think it's also meant to protect from potential mistakes in handling of hard disk decommissioning which presumably is a common thing with data centers.
Used to be, but e.g. where I work any decommissioned drive has to be DBANed (if it's spinning platters) or secure-erased (SSDs). If it can't be for some reason (e.g. it has failed) it needs to be physically destroyed. I would hope most data centers have similar policies in 2026, but that may be optimistic I guess.
Hm yeah, I always think of encryption at rest as "the drive handles encryption itself", rather than "we encrypted these archives before we wrote them", but fair enough.
Not very strange but E2EE is thrown around a lot and everyone interprets it differently. And in some cases the expectations are unrealistic.
Take a messenger app using a server as middleman. E2EE means only the 2 users get to see the content, not the middleman company server. For Oura there’s only a user and the company server and a lot of people assume Oura can’t read the data, like the Signal or WhatsApp servers can’t read the data because of E2EE. The marketing usually allows or encourages this misunderstanding.
If they claim E2EE though, the interface between the user and the service (the ring or at worst the app) should mandate the encryption and the data should be decrypted only at the other end on Oura’s servers. If at any point in between these 2 ends the data is decrypted then it’s not E2EE.
I wouldn't be surprised if they could. Probably not while it's in your pocket though. They're packed with sensors that can pick up a lot. Just putting a phone on a table with a keyboard on it is enough for it to be able read your keystrokes. They can certainly tell when you're doing something that should be raising your heart rate.
That sounds more like "legal asked for list of everything we collect, and anything we could collect by accident or inference" - and it leading to hilarious results - which I have seen firsthand before.
We own a Kia. I'd offer to do a GDPR data request, but my data would not give us any useful signal here lol.
Target infamously was inferring when teenage girls were pregnant before their parents knew based on reward card data records of single merchant retail purchases.... in 2002.
Tech companies when they speak to VCs: look at all the creepy things we can infer with ooodles of aggregated data and AI to maximize targeted ad revenue, we're worth 50x what an equivalent non-tech company in our sector is valued, because of all the things we can do with all that data from all those people together
Tech companies when they speak to their customers: oh you're so silly to even ask about privacy, what possible utility could there be in that single isolated variable?
Accidentally inferring. They were using basic machine learning to send coupons for predicted future purchases based on past purchases and general trends. And as far as I’m aware, it only happened once (or was only publicized once).
Most likely biometric data on crime suspects to correlate with other forensic data. Obtaining this data on a case by case basis is expensive so it is most likely to be used in high stakes cases like murders or bank robberies where police and prosecutors need to show a win.
For example, A is known to have been an associate of B. B died violently at a certain time and date. Phone data put both of them in the same general area around that time. A seems evasive and won't talk. But A's biometric data reveals intense physical activity around the time of B's death...
Other suggestions in this thread like algorithmically making things worse for people in general are predicated on continual availability for a whole deanonymized population.
Buys your heart rate and blood oxygen data from Oura. Collects your iris data from Eyez. Purchases your fitness data from Borg. Sees your purchasing patterns through Krump. Knows everything you've said online through Gwimp. Gets your sequenced DNA from FamaTree. Tracks your location data from, well, nearly every app in existance.
What could they possibly do from this single variable???
Ordering a taxi after running outside of US? Probably missed some mass transport. Raise the price boys... like good old Uber back in the day based on iphone battery level. Really the possibilities are endless if you're evil.
Bad health? Raise the insurance premiums? Or anything more evil I can't think of.
They'll know when and how often you're awake or sleep (including how well you slept), sick, fucking, drunk or high, anxious or upset, relaxed, shitting, menstruating, medicated, etc. Combined with other data and tracked over time there is a shocking amount of intimate information you can get from just those two things which is why companies like Oura and Fitbit are so eager to get their hands on it.
No one seems to care anymore, but a big issue that people were concerned about in the 2000s was the switch from 'I know more about me than the blob (corps, gov, etc) does' to, 'I need the blob to remind me where the hell I was that day'. Heart rate and blood oxygen data are hard to exploit data points but not impossible(1), but facing an accusation from someone who knows more about your movements than you do is an uncomfortable scenario. Of course right now, if you're facing an acusation of this type, odds are it's legitimate, or if not, defenseable, but that was the case 15 years ago in Türkiye, but isn't now. Things change.
(Note 1:"Dr. Bootlicker, the defendant wants the court to believe that she calmly placed herself between the agent and the minor he was trying to apprehend, and asserts that the agent's claim, that the defendant's actions constitute assault, is, in her words, 'ridiculous'. But am I correct in understanding that you view minutes 8 and 9 of the biometric data submitted to the court as characteristic of significant physical exertion that might be similar to that undergone by an assailant while commiting an assault?")
What will the government even do with my heart rate and blood oxygen data?
It's not in isolation. It's in aggregation. So you end up with
"Mr. Smith's heart rate goes off the charts for six minutes every time his phone visits this apartment building in the middle of the night and is within radio range of Ms. Jones' phone."
I guess neither of us are hacker enough. I can't come up with anything interesting [that wouldn't be more readily available via cell networks], either.

I considered an Oura but went with an Apple watch instead. I turned on Advanced Data Protection on the paired iPhone for peace of mind. No other large data providers really provide anything equivalent to ADP’s E2EE protection with zero access encryption, especially in the consumer space for activity trackers.
I was stuck between the two, Oura won for its better sleep tracking and battery life.
I suppose one option would be to enable data syncing to Apple Health, and periodically delete/create new Oura accounts to purge historical health data. Not a great workflow, but would let you benefit from E2EE with Apple Health while using Oura (assuming Oura’s “delete account and all data” does what it claims)
Yup. It’s a bit of a pain, but you don’t have to use the connect app. Devices and data can be accessed with direct USB connection as standard storage. You will lose some features and I think firmware updates become difficult (or impossible?)
I believe they can be used offline, at least the last time I used Garmin I was able to set it up such that I could sync it to Golden Cheetah. It took some jumping through hoops and an older watch version to get it work, as I recall. For serious runners and hikers, the hardware is better than Apple.
I'm only a casual fitness tracker so the Apple Watch fits my needs better.
This is why although I don't love my Apple Watch, I'm not using anything else. It's very sensitive data and Apple is the only company worth trusting with it. They're not perfect but compared to others there's no competition.
A great example is Apple's new in-house cellular modem design, which gives you the option to stop reporting your exact location to your cellular provider.
The best way to prevent the Feds from getting access to customer data is to not collect it in the first place.
Apple has a great PR (propaganda) department that has convinced many people they respect your privacy. In truth, they do not. They're "better" than Google, but only slightly. And only so slightly that realistically it doesn't matter.
"Apple is taking the unprecedented step of removing its highest level data security tool from customers in the UK, after the government demanded access to user data."
Did you just post an article where Apple refused a UK government order to weaken their encryption as "proof" that Apple doesn't respect customer privacy?
Also, the US Government has already demanded that Apple weaken device encryption.
Apple fought it in court, and the government dropped their demand rather than set a privacy precedent they wanted to avoid.
Google's Health Connect system doesn't share this data either (without a consent prompt for third party apps, off course). This is to the point where I wish it would just support some kind of sync, because two devices hooked up to the same accounts need a third party app to transfer the health info.
Apple is subject to the same laws Oura is. The competition is too.
Yeah there's no one I'd trust with my personal data except Apple. Their track record of refusing to bow down to the feds has been golden. 24 carat infact.
Apple literally removed encrypted file storage as a feature in the UK rather than comply with demands for access to encrypted customer data from the UK government.
Previously, they refused US government demands for a backdoor that would allow them to unlock locked devices.
> Apple literally removed encrypted file storage as a feature in the UK rather than comply with demands for access to encrypted customer data from the UK government.
Does that mean that instead of UK government accessing the data (through a backdoor), UK government can now access to data (because it's not encrypted at all)?
After Apple's announcement that they would remove encryption from UK users rather than weaken it, the bad press and public pressure forced the UK government to back down.
Maybe, weren't it for the fact that we're having age verification and IDV ("protect the kids"), hardware attestation, removal of 3rd party APKs, etc. heaved upon us.
We've never had so many threats to our privacy and liberties heaved upon us, and the rate is accelerating.
> Cook conveyed to lawmakers that device-level age assurance proposals should not require the collection of sensitive data like birth certificate or social security number, and that parents should be trusted to provide the age of a child when creating a child's account. Any data used for determining age should not be kept by app stores or developers, according to Apple.
It's been over a decade since the Snowden revelations. We know full well that the large tech companies collect massive amounts of your personal data and secretly share it all with the US government. Not requests, not occasionally, not some - everything. And there are even formal mechanisms for this, like National Security Letters, which essentially guarantee silence.
So, why are we seeing articles like this, which raise suspcision that maybe a wearable smart-device company _might_ be sharing _some_ data, _sometimes_? Or expectations of voluntary transparency?
Yes, the government spies on you. Not because you're important, but because they spy on everybody. It's cheap, convenient and has no negative political consequences (so far).
All this said I'm more concerned about Automatic Content Recognition (ACR) on smartTV you buy in the store and never even realize it's phoning home with everything you watch...
I wouldn't use Apple TV, Shield or other proprietary black boxes if you want a private setup. Linux on a mini-PC with Plasma Bigscreen, your own over-the-air antenna for local TV, VacuumTube for YT, and the high seas for other content.
I'm certain there are a non-zero number of TVs that either attempt to auto-join popular wifi hotspots (xfinity/tmobile/starbucks/etc.) and/or have cellular connections for telemetry.
Thinking more on this I think a business opportunity in the future will be companies that design hardware stacks that can go in random appliances that can gather usage information in the name of telemetry.
I give it +/- 5 years before an OTS coffee maker at walmart phones home.
I sat in a meeting at a data broker in 1998 where one of their product managers was strangely proud about how they could determine menstrual cycles from purchase records. It wasn't just hygiene products either. They already have that data and manipulate women with targeted ads timed for the optimal receptivity.
From what I understand, they can get call records and subscription info w/ administrative subpoenas, but this is the first I've heard of them being able to get location data without a warrant.
Assuming you meant directly from the telcos and not from the data broker loopholes - in which case pretty much anyone should be able to do that. Emails and texts they still need a warrant for.
Great, so they can further extrapolate what exact locations you get nervous / are more relaxed / walk more quickly… the understated problem with PII isn’t about any single data point, it’s about combining data to make probable inferences.
The ring doesn't have gps but its app requires location permission so it gets it from your phone. It continually asks me to turn on background sync, which would presumably upload my location regularly as well. I decline and only allow location when the app is open to sync.
If your concern is that the government may access the data, whether it's covered by HIPAA or not is irrelevant, because HIPAA allows government access. Though yes, it would still be better than non-HIPAA in general.
I will once again proselytize for the new pebble time 2 (I am quite a fan of it). Open source and comes with standard sensors for health monitoring (6 axis imu, heart rate monitor, SpO2). Health data can be kept and analyzed on your phone and there are various apps that can do so. Suffice to say there are “surveillance-free” options out there, and if you’re not satisfied with current app options it is easy to hack your own together

Illinois has a tight biometric-privacy law [1]. I’d bet Oura isn’t particularly careful about prohibiting e.g. a Texas police department querying the protected information of Illinois residents.

Why would they be careful, given that the chances of any serious consequences for ignoring such provisions are effectively zero?
> given that the chances of any serious consequences for ignoring such provisions are effectively zero?
I’m assuming that Oura are assuming that this—the Illinois BIPA is toothless—is true. It is not [1].
[1] https://www.wilmerhale.com/en/insights/blogs/wilmerhale-priv...
Yeah I’ve probably gotten $100 in class action money from that law so far.
Why would they be careful, given that the chances of any serious consequences for ignoring such provisions are effectively zero?
Your cynicism is at odds with reality.
I got a check for nearly $500 because when I was an Illinois resident, one of the SV tech companies violated that law.
All it takes is one or two people to get in the ear of the right class action lawyer, and ignoring the rules quickly becomes expensive.
Or you could just grouse on HN and accomplish effectively zero.

False. E2EE is centered on a given user. So long as the phone would be viewed as "yours" (ie inside your personal security boundary) by a reasonable person then it is clear that the data is E2E encrypted.
As the sibling comment notes the common issue is providing a web interface. It isn't so simple to have a remote server dish up a nice UI with lots of convenient functions while only decrypting the data on the client side. It can certainly be done but it requires developers that know what they're doing and management willing to budget for it.
> If the ring uses Bluetooth to sync the data to your phone and the phone syncs data to the Oura servers, but the data is in the clear on your phone, then by this definition, it is not E2E encrypted.
Yet another angle would be that both the phone and the ring are in one's material possession, whereas the cloud is someone else's computer, and to display a nice web UI it has to have the data unencrypted over there.
In that case, the cloud is the potentially untrusted intermediate between the data and one's eyeballs.
All of these are equally valid, it all depends on what is your threat model.
It also doesn't sound like its encrypted at rest. Perhaps each in-transit is held to be a unique e2e IP exchange?
Encrypted at rest means something different. It means if you pull the hard drive out no one can decrypt it. Not that it is encrypted in the database.
Does encryption at rest actually do much? The percentage of attacks that were perpetrated by people getting physical access to a drive must approach zero.
I think it's also meant to protect from potential mistakes in handling of hard disk decommissioning which presumably is a common thing with data centers.
Used to be, but e.g. where I work any decommissioned drive has to be DBANed (if it's spinning platters) or secure-erased (SSDs). If it can't be for some reason (e.g. it has failed) it needs to be physically destroyed. I would hope most data centers have similar policies in 2026, but that may be optimistic I guess.
Depends on what kind of data is in question. Backups and old incremential data can stay encrypted while disks are otherwise in use.
Hm yeah, I always think of encryption at rest as "the drive handles encryption itself", rather than "we encrypted these archives before we wrote them", but fair enough.
Not necessarily the drive, but yeah, where standards mandate encryption at rest you need to have the files on the live disk encrypted.
Usually it's much less of a headache to luks/bitlocker/SED the whole drive so that you don't have to worry about swap files and logs
Unless the attacker is law enforcement.
Law enforcement will just get you to give them the keys.
Law enforcement of another jurisdiction won't, but can try to snoop into the data.
You are conflating end-to-end encryption with encryption at rest.

> everyone interprets it differently.
No, they don't. You're spreading misinformation. If the service provider can see the data then it is not E2EE. There is no room for negotiation here.
Did Oura claim E2EE? If so, are they physically capable of handing over the decrypted data? That's the only thing we need to know.
Let me be perfectly clear that any service provider that claims E2EE while having access to user data is committing blatant fraud.
Is it from the evil govs of China or Russia? Oh, no...

Judging by ads for cell phone service, most people pay more than that per month to be monitored by the Feds.

Garmin can be used completely offline?
AFAIK, they even have some watches with no radio hardware so that they can be used in sensible environments.
Yup. It’s a bit of a pain, but you don’t have to use the connect app. Devices and data can be accessed with direct USB connection as standard storage. You will lose some features and I think firmware updates become difficult (or impossible?)
I think firmware updates and even map routes can be uploaded offline by mounting the watch as a USB mass storage device?
I wish Casio, Polar, Suunto and others provided this functionality.
There is some community software for Polar that enables offline data exchange, but it is a bit hacky, and OFC no firmware updates.
Suunto used to have a really good offline solution, but they discontinued that and moved to the cloud.
Go through the Garmin Express desktop app for firmware updates.
I’m probably missing something, but I can’t think of anything you lose if you don’t use the phone app.
I believe they can be used offline, at least the last time I used Garmin I was able to set it up such that I could sync it to Golden Cheetah. It took some jumping through hoops and an older watch version to get it work, as I recall. For serious runners and hikers, the hardware is better than Apple.
I'm only a casual fitness tracker so the Apple Watch fits my needs better.
Oh! The Audacity!
This is why although I don't love my Apple Watch, I'm not using anything else. It's very sensitive data and Apple is the only company worth trusting with it. They're not perfect but compared to others there's no competition.
A great example is Apple's new in-house cellular modem design, which gives you the option to stop reporting your exact location to your cellular provider.
The best way to prevent the Feds from getting access to customer data is to not collect it in the first place.
You may want to reevaluate.
Apple has a great PR (propaganda) department that has convinced many people they respect your privacy. In truth, they do not. They're "better" than Google, but only slightly. And only so slightly that realistically it doesn't matter.
"Apple is taking the unprecedented step of removing its highest level data security tool from customers in the UK, after the government demanded access to user data."

It happened in the UK; it will not be long before it happens in the US.

Did you just post an article where Apple refused a UK government order to weaken their encryption as "proof" that Apple doesn't respect customer privacy?
Also, the US Government has already demanded that Apple weaken device encryption.
Apple fought it in court, and the government dropped their demand rather than set a privacy precedent they wanted to avoid.
It's brilliant how they've laundered their "privacy" reputation through Google etc. and people believe it so fully.
Google's Health Connect system doesn't share this data either (without a consent prompt for third party apps, off course). This is to the point where I wish it would just support some kind of sync, because two devices hooked up to the same accounts need a third party app to transfer the health info.
Apple is subject to the same laws Oura is. The competition is too.
I believe the Apple one is E2E encrypted so they physically can't give useful data. Thats the core issue with Oura here.
Apple might be pretty good now. There's no assurance they always will be.
Yeah there's no one I'd trust with my personal data except Apple. Their track record of refusing to bow down to the feds has been golden. 24 carat infact.
In the US. Apple's policies are flexible when it comes to other nation states.
All it takes is a political sea change for E2EE to go away.
Apple already has to hand over a wealth of information when asked by the feds.
Apple literally removed encrypted file storage as a feature in the UK rather than comply with demands for access to encrypted customer data from the UK government.
Previously, they refused US government demands for a backdoor that would allow them to unlock locked devices.
> Apple literally removed encrypted file storage as a feature in the UK rather than comply with demands for access to encrypted customer data from the UK government.
Does that mean that instead of UK government accessing the data (through a backdoor), UK government can now access to data (because it's not encrypted at all)?
Nope.
After Apple's announcement that they would remove encryption from UK users rather than weaken it, the bad press and public pressure forced the UK government to back down.
Not exactly. Apple kept it for existing users but stopped offering it to new users. So new users are vulnerable.
Nope.

"Things might change in the future" is a perfectly general statement which applies to any state of affairs which is not restricted by natural law.
That makes it very nearly meaningless.
Maybe, weren't it for the fact that we're having age verification and IDV ("protect the kids"), hardware attestation, removal of 3rd party APKs, etc. heaved upon us.
We've never had so many threats to our privacy and liberties heaved upon us, and the rate is accelerating.
Apple certainly lobbied against this stupidity.
> Cook conveyed to lawmakers that device-level age assurance proposals should not require the collection of sensitive data like birth certificate or social security number, and that parents should be trusted to provide the age of a child when creating a child's account. Any data used for determining age should not be kept by app stores or developers, according to Apple.

I don't trust them.

It's been over a decade since the Snowden revelations. We know full well that the large tech companies collect massive amounts of your personal data and secretly share it all with the US government. Not requests, not occasionally, not some - everything. And there are even formal mechanisms for this, like National Security Letters, which essentially guarantee silence.
So, why are we seeing articles like this, which raise suspcision that maybe a wearable smart-device company _might_ be sharing _some_ data, _sometimes_? Or expectations of voluntary transparency?
Yes, the government spies on you. Not because you're important, but because they spy on everybody. It's cheap, convenient and has no negative political consequences (so far).

IPOing soon at $11B btw
All this said I'm more concerned about Automatic Content Recognition (ACR) on smartTV you buy in the store and never even realize it's phoning home with everything you watch...
> I'm more concerned about Automatic Content Recognition (ACR) on smartTV
You’re more concerned about privacy when it comes to TV viewing than medical data? What a strange hijacking of a serious thread…
When you buy a medical data collection device and it collects medical data that’s not exactly a surprise
Whataboutism in fancy clothes.
If you're concerned about that do not give internet to your tv and use any kind of tv box instead (shield tv, apple tv, etc).
I wouldn't use Apple TV, Shield or other proprietary black boxes if you want a private setup. Linux on a mini-PC with Plasma Bigscreen, your own over-the-air antenna for local TV, VacuumTube for YT, and the high seas for other content.
How long until they have built in cellular or use a mesh?
I'm certain there are a non-zero number of TVs that either attempt to auto-join popular wifi hotspots (xfinity/tmobile/starbucks/etc.) and/or have cellular connections for telemetry.
Thinking more on this I think a business opportunity in the future will be companies that design hardware stacks that can go in random appliances that can gather usage information in the name of telemetry.
I give it +/- 5 years before an OTS coffee maker at walmart phones home.
with things like amazon's sidewalk you might not have any choice https://en.wikipedia.org/wiki/Amazon_Sidewalk
So that TV box can phone home instead of your smart TV? What's the point?
Use a TV box that doesn't phone home, obviously. Also, don't buy a smart TV but a monitor.
Different homes are being phoned. If that matters.
We can not trust any government here.
Another reason to add to my list to justify not wearing my Apple watch and moved to a mechanical watch.
Oura doesn't even have GPS does it?
Government can already get ALL your celltower locations without a warrant
AND read all your emails and text messages that are over 6 months old, without a warrant
In a society where women are being prosecuted for medical procedures, menstrual data becomes very risky to have handed over.
I sat in a meeting at a data broker in 1998 where one of their product managers was strangely proud about how they could determine menstrual cycles from purchase records. It wasn't just hygiene products either. They already have that data and manipulate women with targeted ads timed for the optimal receptivity.
Probably this yeah. Your location data can be obtained from other devices than your own, but this medical data cannot.
From what I understand, they can get call records and subscription info w/ administrative subpoenas, but this is the first I've heard of them being able to get location data without a warrant.
Assuming you meant directly from the telcos and not from the data broker loopholes - in which case pretty much anyone should be able to do that. Emails and texts they still need a warrant for.
Great, so they can further extrapolate what exact locations you get nervous / are more relaxed / walk more quickly… the understated problem with PII isn’t about any single data point, it’s about combining data to make probable inferences.
The ring doesn't have gps but its app requires location permission so it gets it from your phone. It continually asks me to turn on background sync, which would presumably upload my location regularly as well. I decline and only allow location when the app is open to sync.
Location is used for tracking distance/speed for certain activities and measuring VO2 max levels, and for finding a lost ring.
They already know where your phone is…
OURA is a joke. My GF bought two for us and after a week I made her return them due to non stop dark patterns coming out of that company.
Everything about that company is disgusting.
Such a shame, too. I was eager to learn more about my health.
Can you elaborate?
I was definitely interested in some sort of comprehensive sensor bundle for my healthcare.
But every one of these devices demands some Android/Apple app, and shipping all my health data to basically non-HIPAA data brokers.
Id be all over a local-only no-data-exfiltration health tracker. But the companies do NOT want to provide that.
I, uh, guess, "go surveillance capitalism", for more choices?
If your concern is that the government may access the data, whether it's covered by HIPAA or not is irrelevant, because HIPAA allows government access. Though yes, it would still be better than non-HIPAA in general.
I will once again proselytize for the new pebble time 2 (I am quite a fan of it). Open source and comes with standard sensors for health monitoring (6 axis imu, heart rate monitor, SpO2). Health data can be kept and analyzed on your phone and there are various apps that can do so. Suffice to say there are “surveillance-free” options out there, and if you’re not satisfied with current app options it is easy to hack your own together
Many times GadgetBridge* can be used instead of the official app

HIPAA is completely irrelevant to any of this. Ours is technically HIPAA complaint because the data they process is not subject to HIPAA.
In overly simple terms, if insurance is not involved, then it’s not subject to HIPAA.
I am using Withings in combination Tredict. Both GDPR-compliant.
