Privacy policy
Last updated 25 August 2026
HakiCheck collects nothing. What you type about your health is read by a language model running on your own iPhone and never leaves it. There is no account, no server, and no analytics.
All of it lives in the app's own storage on your iPhone.
On your iPhone, using Apple's on-device Foundation Models framework. Your description is not sent to us, to Apple, or to any other service for processing. There is no cloud fallback, no remote model, and no key to a third-party API in the app. HakiCheck makes no network requests at all.
If you grant access, HakiCheck reads recent readings from Apple Health to check whether any of them raise the urgency of what you described. This is read-only. Nothing is written back to Health, nothing is copied out of it, and no reading is stored beyond the assessment it was used for. Access is optional and the app works without it. You can revoke it at any time under Settings › Health › Data Access & Devices.
Nothing. No analytics package, no crash reporting service, no advertising identifier, no third-party SDK. We have no way to identify you as a user and no way to see anything you enter. There is no database on our side to breach, subpoena, or sell.
What you type into this app is health information about you, and in most other places health information is exactly what gets collected, aggregated, and eventually sold or leaked. Keeping it on the device is the whole design, not a setting. Because none of it reaches us, there is nothing for us to disclose to anyone, under any circumstance.
Clear individual entries in the app's history, or delete the app to remove everything at once. We hold no copy, so there is nothing to request from us.
HakiCheck is intended for adults assessing themselves. It is not directed at children under 13, and we do not knowingly collect information from anyone.
HakiCheck is a consumer app, not a health care provider, and it is not covered by HIPAA. That framing tends to imply protections that do not apply here, so it is worth being direct: the reason your information is safe is that it never leaves your phone, not that a regulation obliges us to guard it.
If this policy changes, the updated date above changes with it. If the app ever needed to send anything off the device, that would be a material change, it would be opt‑in, it would be visible in the app, and this policy would be rewritten before it shipped.
