Samsung Health now deletes the data of users who refuse to consent to their health information being used to train Samsung's AI models — that's the new privacy policy for the service. Put simply: either you let Samsung feed your heart rate, sleep, and workout data to its neural networks, or the app wipes your history entirely. The news has already picked up 132 points and 32 comments on Hacker News — people are angry about the ultimatum.
What actually happened
Samsung updated its privacy policy for Samsung Health. Now, if a user declines to have their data processed for training the company's AI models, there's no option to simply "leave things as they are." Opting out effectively means deleting the health statistics accumulated over months or years — steps, sleep, heart rate, workouts. Previously, this kind of data could be stored locally or synced without mandatory participation in AI programs. Now that middle ground is gone: consent or deletion.
Why this matters beyond Galaxy Watch owners
It might seem like this only concerns wearable fans, not people building or consulting on AI. But it's a symptom of a broader trend: large companies are increasingly using user data to train models, framed as formal "consent." Personal health data is one of the most sensitive categories, and Samsung putting it at risk of deletion shows where the market is heading. If you advise clients on adopting AI tools, this is exactly the kind of case you'll need to explain — where convenience ends and privacy risk begins.
AI and personal data protection: where the line is
The core issue raised in the Hacker News comments isn't that data is used to train models at all — it's the lack of an alternative. Samsung's earlier privacy policy implied a choice: opt in and participate, or opt out and simply not participate, while keeping your data. The new scheme removes the neutral option. That changes the ethics of AI and personal information altogether: consent stops being voluntary when the alternative is losing your data.
What to do if you use Samsung Health
1. Check your privacy settings in the app before the policy takes effect — export your history now if it matters to you.
2. Don't accept the new terms automatically — read exactly what the consent covers: aggregated statistics only, or specific health metrics.
3. Consider alternatives for storing health data if you're not comfortable sharing it for AI training.
4. Watch for similar changes at other services — Samsung is unlikely to be the last company to tie feature access to mandatory AI training consent.
At the very least, the Samsung Health story is a good reason to reconsider what data you hand over to which services in exchange for smarter AI features.
