The following notes provide a simple overview of what happens to your personal data when you use the Offline app. Personal data means any information that can be used to identify you personally. Detailed information on data protection follows in the sections below.
We collect data that you actively provide when registering and using the app (e.g. profile details, interests), and data that is generated through your use of the app (e.g. event participation, chat messages, ratings).
Your data is used to suggest personalised events, connect you with other users and provide app features. A subset is sent to OpenAI for AI-assisted event generation (see section 10).
The party responsible for data processing under this site is:
Zest UG (haftungsbeschränkt)
Stadtplatz 39, 84529 Tittmoning, Germany

With your explicit permission, we use your device's location (precise GPS) to suggest events near you, surface friends in your area and rank venues by distance. The location is read on the device only when you actively use a location-aware feature and is transmitted to our backend (Firestore) so we can match you to events in the right city. You can revoke the permission at any time in your device's system settings.
Processing of your profile and usage data is based on contract performance under Art. 6(1)(b) GDPR, since this data is necessary to provide the app's features. Where data is processed to improve our services, we rely on our legitimate interest under Art. 6(1)(f) GDPR.
Your data is stored for as long as you use the app. You can delete your account permanently at any time under Settings > Delete account, or via offline-events.de/delete-account. When you delete your account, all personal data — including profile, posts, event participations and chat messages — is deleted immediately and irreversibly. Deleted data cannot be restored.
Where statutory retention obligations apply, the relevant data is kept until the respective period ends and then deleted.
We share your personal data with third parties only in the following cases:

To generate personalised events, your profile data and activity preferences are transmitted to OpenAI, L.L.C., 3180 18th Street, San Francisco, CA 94110, USA. OpenAI processes this data to produce matching event suggestions via the GPT-4o language model. The transmitted data includes information such as interests, age, city and activity preferences. No full real names or directly identifying contact information are transmitted.
The legal basis for this processing is Art. 6(1)(b) GDPR (contract performance), since AI-assisted event generation is a core feature of the app, as well as Art. 6(1)(f) GDPR (legitimate interest in improving our services). Data transfer to the USA is based on the EU Standard Contractual Clauses.

To continuously improve the quality of generated events, we use positive user feedback (high ratings, event participation) as the basis for fine-tuning our AI model. Only anonymised prompt/response pairs are used. No directly identifying data such as names, email addresses or user IDs is included. The resulting training data may be transmitted to OpenAI for model optimisation.
The legal basis is our legitimate interest in improving the service under Art. 6(1)(f) GDPR.
To comply with content-safety policies and store guidelines, every image uploaded to the app is automatically analysed by Google Cloud Vision SafeSearch (Google Ireland Limited). Content classified as adult, violent or otherwise inappropriate is automatically removed. Processing is based on Art. 6(1)(f) GDPR (legitimate interest in maintaining a safe platform) and Art. 6(1)(c) GDPR (legal compliance with platform regulations).
