HaffyThis document explains how the Haffy application (hereinafter referred to as the "App") handles your data. We respect your privacy and comply with data protection requirements under GDPR (EU) and CCPA (California, USA) standards.
1. Data Controller and Contact
The operator of the App and the controller of your personal data is Stanislav Grünfeld. For any questions, data deletion requests, or to exercise your rights, please contact us at: haffy.app@gmail.com.
2. Data Processing and Cloud Backup
Local mode (default): Data about your dogs, photos, and journal entries are stored locally on your mobile device. Except for the features described in Sections 3 and 4, the App does not send the content of your records to our servers. This also applies to signed-in users without active cloud backup.
Sign-in (account): If you register and sign in (using your Google Account or Apple Account), we only obtain your email address and necessary authentication tokens from the sign-in services.
Cloud backup: Cloud backup is available as part of Haffy Premium (and for selected earlier accounts). When active, the data you enter (dog profiles, journal entries, saved contacts, user settings, and uploaded photos) is securely backed up to Firebase cloud storage (provided by Google LLC). Data may be stored on servers located in the USA; its protection is ensured by standard contractual clauses and Google's security mechanisms. If another user shares a dog profile with you, that dog's data is stored in the owner's cloud storage.
3. AI Features and Sensors
AI assistant (Haffy Chat): Your queries, any attached photo, and basic details about the selected dog (name, sex, breed, age, weight, and profile notes) are sent to Google (Gemini API) so the AI can respond. These queries are not linked to your identity. Never share your sensitive personal data in the AI chat.
Camera and microphone: The App requires access to the camera (to upload dog photos) and the microphone (for voice input in the chat). We do not store audio recordings on our servers; they are used only for a one-time conversion to text. Photos are stored either locally or in your personal cloud account within the App (if you are signed in and have active cloud backup).
4. Usage Statistics and Purchases
Anonymous usage statistics: To improve the App, we collect anonymous data about how it is used — for example, which screens users visit and which features they use (e.g., "journal entry added"). This data is processed by Firebase Analytics (Google LLC). It never includes the content of your records, names, email, or photos, is not linked to your identity, and is not used for advertising tracking across apps.
Subscriptions and purchases: If you purchase Haffy Premium (a subscription or a one-time purchase), the payment is processed by the App Store (Apple) or Google Play. Your purchase status is managed for us by RevenueCat, which receives only your account identifier and purchase information — never the content of your data in the App.
5. Your Rights (GDPR and CCPA)
No sale of data: The operator does not and will never sell your personal data to third parties.
Access to data: You can edit or delete your data at any time directly within the App interface.
Right to erasure: You can permanently delete your account and all data directly in the App under More → "Delete account & data". If you use the App without signing in, you can also delete your data simply by uninstalling the App. Alternatively, contact us at haffy.app@gmail.com and your data will be permanently deleted without delay.
