1. Who we are
Aevo is developed and operated by Vladimir Ciumacenco. References to "we," "us," or "our" refer to the Aevo app and its developer. You can reach us at vladimir.ciumacenco27@gmail.com.
2. Data we collect
Health data (via Apple HealthKit): With your explicit permission, Aevo reads the following from Apple Health:
- Heart rate and heart rate variability (HRV)
- Sleep analysis and sleep stages
- Active energy burned and step count
- Resting heart rate and body temperature
- Workout data and activity rings
This data is read locally on your device. It is never uploaded to our servers in identifiable form.
Meal data: When you use the Meal Scan feature, photos you take are sent to OpenAI's API to identify food and estimate macronutrients. These images are processed and immediately discarded — OpenAI does not store them beyond the API call per their enterprise data processing agreement.
Account data: If you create an account, we store your email address and a secure identifier via Firebase Authentication. This is used only to sync your app preferences across devices.
AI Coach conversations: Messages you send to the AI Coach are sent to OpenAI's API along with relevant anonymized context from your health data (e.g., "user's HRV today is 62ms"). These conversations may be stored on your device for continuity but are not stored on our servers.
Purchase data: In-app purchases are handled by Apple and RevenueCat. We receive purchase status (active/expired) but not your payment card details.
Crash reports and analytics: We may collect anonymized crash logs via Firebase to help us fix bugs. This data contains no health information.
3. How we use your data
- To calculate your real-time energy score
- To run our 14 AI engines and generate personalized recommendations
- To provide AI Coach responses relevant to your health context
- To sync your preferences across your devices
- To improve app stability through anonymized crash reports
We do not use your data for advertising, profiling for third parties, or selling to data brokers.
4. Data sharing
We share data only with these third-party services, each under a data processing agreement:
- OpenAI — for AI Coach responses and Meal Scan. Data is sent over encrypted HTTPS and not retained by OpenAI beyond the request.
- Firebase (Google) — for authentication and anonymous crash analytics.
- RevenueCat — for managing in-app subscription status.
- Apple — HealthKit data stays within Apple's ecosystem; we access it only on-device.
5. Data storage and security
Your health data is stored locally on your iPhone using iOS secure storage (Keychain and Core Data). We use HTTPS for all network communication. Firebase data is encrypted at rest and in transit.
We retain account data (email, preferences) until you delete your account. You can delete your account at any time from the Settings screen in the app.
6. HealthKit
Aevo's use of HealthKit data is governed by Apple's HealthKit guidelines. We:
- Only access HealthKit data for health and fitness purposes directly related to the app
- Never use HealthKit data for advertising or marketing purposes
- Never share HealthKit data with third parties except as required to provide the service (e.g., anonymized context sent to the AI Coach)
- Never sell HealthKit data
7. Children's privacy
Aevo is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately.
8. Your rights
Depending on your location, you may have the right to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Withdraw your consent at any time (e.g., revoke HealthKit access in iOS Settings)
- Data portability
To exercise any of these rights, contact us at vladimir.ciumacenco27@gmail.com.
9. Changes to this policy
We may update this Privacy Policy from time to time. We will notify you of material changes through the app or by updating the "Last updated" date at the top of this page. Your continued use of Aevo after changes become effective constitutes acceptance of the updated policy.
