1. Overview
TRT AI is an iPhone application focused on testosterone-protocol tracking. We collect the minimum information needed to log your doses, store your lab values, run the on-device AI weekly read, and keep the app reliable.
2. Data we may process
- Account identifiers required for subscription state.
- Dose, injection, vial, pellet and ancillary entries that you log.
- Lab values that you record manually or import.
- Daily signals such as libido, morning erection, energy, mood, sleep, strength and side-effect tags.
- Optional HealthKit reads (weight, waist, resting heart rate, blood pressure) only when you grant permission.
- Diagnostic and crash information used to improve stability.
- Subscription metadata processed through Apple's billing flows.
3. How we use it
- To compute schedules, reminders, charts, trends and the weekly AI read.
- To improve recognition quality on lab PDF imports.
- To prevent abuse and protect account integrity.
- To respond to support requests and lawful requirements.
4. The on-device AI weekly read
The weekly summary uses Apple FoundationModels and runs on your iPhone. No prompt and no input data is sent to a cloud model. Free-text fields are sanitised before being passed to the model. The resulting three-sentence summary is stored locally and may be sent anonymously to our analytics provider for quality monitoring, with identifying details removed.
5. Third-party services
TRT AI relies on third-party providers for analytics (PostHog, EU-hosted) and subscription receipt validation (RevenueCat). Apple manages all App Store payments. We do not sell personal information.
6. Retention
Your dose log, lab values and daily signals live on your iPhone and are removed when you delete the app or use the in-app reset. Analytics events are retained only as long as needed to monitor quality and resolve issues. You may request deletion of any data we hold at any time.
7. Your rights
Where applicable law applies, you can request access, correction, or deletion of personal data. Email contact@trtai.app from the email tied to your account so we can verify the request.
8. Security
We apply technical and organizational safeguards. No system can be guaranteed fully secure, but we continuously improve the controls we apply.
9. Disclaimer
TRT AI provides a tracking surface and a confidence-based AI summary based on the data you enter. It is not medical advice, it does not calculate, recommend or adjust doses, and it does not replace a clinician for any TRT decision.
10. Updates
We may update this policy when features or legal obligations change. Material updates will be reflected by changing the effective date above.
