This page explains which personal data Sonic Online collects, why, and what your rights are (General Data Protection Regulation, GDPR). Sonic Online is a free, non-commercial fan project. Contact: contact@echo-nexus.fr.
1. Data we collect
- Account: your username, your e-mail address and your password (stored only as a secure hash, never in clear text).
- Sign in with Google: if you choose it, Google sends us your e-mail address, your name and a technical identifier of your Google account. We do not receive your Google password and we have no access to your other Google data.
- Game progress: rings, experience, level, emeralds, characters owned and chosen, unlocked zones, records (times shown on the public leaderboards with your username).
- While you play: your position and animation in the game (sent to the other players of the same area) and the chat messages you send (shown to the other players, not kept after they are displayed).
- Technical data: your IP address and connection times, in the server logs, for security (protection against attacks and repeated failed sign-ins).
2. Why we use it
- To create and secure your account and let you sign in (performance of the service).
- To save your progress and run the online game with the other players (performance of the service).
- To send you the e-mails needed for your account: address confirmation and password reset. No newsletter, no advertising.
- To protect the service against cheating and attacks (legitimate interest).
3. Sharing
Your data is never sold or rented. Only your username, level, character, records and chat messages are visible to other players. The servers are hosted in France (OVHcloud). E-mails are sent through our e-mail provider. Google only takes part if you choose to sign in with Google.
4. How long we keep it
- Account and progress: as long as your account exists. Accounts inactive for 3 years may be deleted.
- Server logs: 12 months at most.
- Backups of the game database: 14 days.
5. Your rights
You can access, correct or delete your data, ask for a copy of it, or object to its use: write to contact@echo-nexus.fr from the e-mail address of your account. Deleting your account deletes your progress. You can also file a complaint with the French data protection authority (CNIL, www.cnil.fr).
6. Cookies
The sign-in page only uses the cookies needed to keep you signed in. No advertising or tracking cookies.
