Welcome to Havyu AI. We are committed to protecting your privacy. This policy explains how our application collects, uses, and protects your information, including workout and habit data, authentication data, voice input, and technical diagnostics.
We are based in the UK and can be contacted at havyulabs@gmail.com.
Havyu AI does not track you across other companies’ apps or websites, and we do not use the App Tracking Transparency framework. We do not sell your data, and we do not use your data for third-party advertising. Our diagnostic tools are configured to strip personally identifiable information by default.
We use your microphone only when you choose to log workouts via voice commands. When you dictate a set, your speech is transmitted to your device’s native operating system speech-recognition service (Apple or Google) to convert it to text. We do not store or intercept raw audio on our own servers.
To interpret the resulting text into structured sets and reps, that text may be processed by our AI provider, Google Gemini, as described in Section 5 and subject to the same consent. If you have not granted AI consent, or the AI service is unavailable, the text is interpreted on-device instead.
A future version of Havyu AI may offer optional camera-based movement tracking to help count repetitions. This feature is not active in the current version of the app, and the app does not request camera access during normal use. If we introduce camera tracking in a future release, all visual processing is designed to happen locally on your device — we will not record, store, or transmit your video feed — and we will update this policy before the feature becomes available.
Havyu AI uses Large Language Models (LLMs) to provide coaching insights. To generate your personalized coaching, we transmit your logged habit and weightlifting data to our AI provider, Google Gemini, through our own secure server.
Havyu AI is fully usable without an account. However, you may optionally sign in using Sign in with Apple or Sign in with Google to enable subscription portability and (in a future version) cloud backup of your data.
If you choose to sign in:
You can sign out at any time from Settings, which removes your session from this device. You can also permanently delete your account and all associated authentication data directly in the app via Settings → Delete Account. Alternatively, you may request deletion by contacting havyulabs@gmail.com from your registered email address. We process deletion requests promptly and within 30 days.
Your workout sets, habit check-ins, body weight, sleep, mood, and other personal training data are stored locally on your device in an SQLite database. This data does not leave your device except:
We do not currently sync your workout data to any cloud server. If we add cloud backup in a future version, we will update this policy and request your explicit opt-in before any sync occurs.
Havyu AI offers both Free and Pro tiers. All payments and subscriptions are processed securely through your app store — the Apple App Store on iOS or Google Play on Android. We do not collect, process, or store your payment information on our servers. Subscription state is managed by RevenueCat, our subscription infrastructure provider.
To ensure a stable experience, we use a third-party diagnostic service (Sentry) to capture crash reports and performance data. We configure our tools to strip personally identifiable information by default. This diagnostic data is used only to identify and fix problems and to improve app stability and performance. It is not used to track you and is not linked to your identity where technically avoidable; crash and performance data are associated only with an anonymous device identifier.
We share data with the following third parties to operate Havyu AI:
| Provider | Purpose | Data shared |
|---|---|---|
| Google Gemini | AI coaching | Workout, nutrition, sleep, and mood data, and the text of voice commands when voice logging is used — without name or email (with consent) |
| Supabase | Authentication and (future) cloud sync | Email and user identifier (only if you sign in) |
| RevenueCat | Subscription management | User identifier and entitlement status |
| Sentry | Crash and performance diagnostics | Anonymous diagnostic data |
| Apple / Google Play | App store distribution and in-app payments | Governed by the respective store’s own privacy policy |
Of the parties above, Google Gemini, Supabase, and RevenueCat process data on our behalf as data processors and are bound by data-processing terms requiring them to protect your data to a standard equivalent to the protections described in this policy (Google under its Cloud Data Processing Addendum). Sentry receives only anonymous diagnostic data. Apple and Google Play are independent providers of app distribution and in-app payments and handle any data under their own privacy policies.
You have the right to:
Age Requirement: You must be at least 16 years of age to use Havyu AI. By downloading or using the app, you confirm that you meet this requirement. We do not knowingly collect data from anyone under 16. If you believe we may have collected data from someone under 16, please contact us at havyulabs@gmail.com so we can promptly delete it.
We may update this policy from time to time. Material changes will be highlighted in-app on next launch, and the “Last Updated” date at the top of this document will reflect the change. Continued use of Havyu AI after a change constitutes acceptance of the updated policy.
If you have any questions regarding your data, please reach out to us at: havyulabs@gmail.com
