Privacy Policy
Thaïa respects your privacy
Last updated: 27 July 2026
1. Data collection
Thaïa only collects data necessary for the app to function: your GPS location (to display nearby cultural sites), your email address and your display name (if you create an account), your language preferences, your subscription history (if you subscribe to Thaïa Pro) and a device identifier (if you enable notifications). If you report a problem to us from within the app, we also receive your message, your email address and, where applicable, the photo or video you choose to attach. No data is sold to third parties.
2. Location usage
Your GPS location is used exclusively to display nearby museums and cultural sites, calculate distances and generate itineraries. To display maps and calculate routes, coordinates are sent to our mapping provider; they are not associated with any account identifier. If you turn on the "Even when the app is closed" option (off by default), the app uses background location (the "Always" permission) solely to detect when you pass near a remarkable place and send you a local notification: your position is then processed on your device, is not kept as a history, and is never sent to our servers. We keep no history of your movements and do not sell your location to anyone. You can turn this option off, or disable location access, at any time in the app or in your device settings.
3. Artificial intelligence
Thaïa uses OpenAI's models for chat, photo identification, the voice guide and itineraries. Depending on the feature, this can include the photos you scan, your voice (voice mode) or your messages; we send only the minimum necessary. In line with OpenAI's API terms, this data may be retained temporarily by OpenAI (up to 30 days, for security) then deleted, and is not used to train their models. The app is designed to describe places and artworks, not people.
4. Data storage
Your favorites, visit history and preferences are stored locally on your device, as well as on our secure servers if you have an account. If you allow it — a setting that is on by default and can be turned off at any time in "My preferences" — Thaïa also keeps a profile of your tastes in order to personalize its recommendations. To avoid re-downloading the same content, the app keeps an image and audio cache on your device: this cache never leaves the device and disappears when you uninstall the app. If you delete your account, all associated data is erased from our servers.
5. Security
Communications between the app and our servers are encrypted via HTTPS. Your credentials are stored securely using your device's encrypted storage system (Keychain on iOS, Keystore on Android).
6. Your rights
In accordance with GDPR, you can at any time: access your personal data, correct it, delete it, or request its portability. To exercise these rights, contact us at contact@thaia-app.com.
7. Cookies and trackers
The Thaïa mobile app uses no advertising cookies and does no cross-app advertising tracking. To improve the service, we record which features you use, your journey through the app and the text of the questions you ask the AI assistant; when you are signed in, these records are linked to your account. To detect and fix crashes, we use a third-party diagnostics tool, which receives the device type, the OS version and the error trace. When you report a problem to us from within the app, your account identifier and your email address are attached to the report so that we can reply to you, as is the photo or video you add to it. No advertising identifier is used.
8. Third-party providers
Thaïa relies on a small number of providers, solely to operate the service. None of them is allowed to use your data for its own commercial purposes. A database host — account, favorites, itineraries and preferences; our AI model provider, named in section 3 — processing of the photos, voice and messages sent to the assistant; a mapping provider — map display, geocoding and route calculation, which receives coordinates with no account identifier; a diagnostics tool — crash detection and bug reports; a subscription manager — Thaïa Pro subscriptions; Apple — push notifications and subscription billing. Payment itself is handled by Apple: we never have access to your banking details. We will tell you the identity of any of these providers on request at contact@thaia-app.com.
9. Changes
This privacy policy may be updated. In the event of a significant change, a notification will be sent to you in the app. The last update was on 27 July 2026.
