Deal – Privacy Policy

Last updated: October 15, 2026

Deal ("the app") is a classified-ads marketplace published by over-tech.de. This policy explains what data the app collects, how it is used, and your choices.

1. Data we collect

• Account data: name, email address, phone number and password (the password is handled by Firebase Authentication and never stored in readable form).
• Ads you publish: title, description, price, location (address and, if you allow it, an approximate GPS position), contact phone, photos and the details you choose to add for the category (for example rooms, car brand or school subject).
• Messages: chat messages you exchange with other users, including a location you choose to share.
• Location: only while you use the app, never in the background, and only:
  • when you post an ad, to fill in its address. The GPS position saved with the ad is rounded to about 100 meters, and you can remove it or type the address yourself;
  • when you search for ads "near me" or sort by distance — this position stays on your phone and is not stored;
  • when you tap "share my location" in a chat.
• Photos and camera: only the photos you choose to add to an ad. Object and color detection runs entirely on your device; images are not sent to any AI service.
• Usage data: favorites, reviews, ad view counts and reservations.
• Notifications: if you allow notifications, a push token identifying your phone, used only to tell you about new messages, the approval of your ads and new reviews. It is removed when you sign out or delete your account. You can turn notifications off at any time in your phone settings.

2. How we use data

• To create and secure your account.
• To publish your ads and show them to other users after moderation.
• To let buyers and sellers communicate.
• To show basic statistics (views, number of ads) to administrators.

We do not sell your data and we do not show third-party advertising.

3. Who data is shared with

• Other users: your published ads (including their address and approximate position), your name on your ads and in chats, and your contact phone if you add it to an ad.
• Service providers: Google Firebase (authentication, database and Firebase Cloud Messaging for notifications), Expo (notification delivery), Cloudinary (photo storage) and open.er-api.com (exchange rates; no personal data is sent). Turning a GPS position into an address is done by your phone's own location service.

4. Storage and security

Data is stored on Google Firebase and Cloudinary servers, protected by encrypted connections (HTTPS) and access rules that limit each user to their own private data.

5. Your rights

You can edit your ads at any time. You can delete your account and all associated data directly in the app (Menu › Delete my account), or by emailing us at the address below; email requests are processed within 30 days.

6. Children

The app is not intended for children under 13 and we do not knowingly collect their data.

7. Terms of use

Use of the app is subject to our terms of use, including zero tolerance for objectionable content and abusive users.
