Privacy policy

Racquet for iOS · Updated October 13, 2026

This policy covers the Racquet iOS app maintained by Kosta Karathanasopoulos. The Chrome extension has a separate policy.

Racquet has no ads, analytics or user accounts. The app does not send your solo scores or saved rallies to the developer.

Your game

Solo play runs on your device and works offline. Your best score, saved rally, multiplayer nickname and help preference are stored locally. Some preferences are copied into iOS app storage so they survive a restart of the game view. There is no cloud score service.

Touch input controls the racquet. The app uses screen dimensions and your reduced-motion preference for display. It does not request access to your camera, microphone, contacts, location or advertising identifier. Game sounds are generated on the device.

Optional multiplayer

Multiplayer starts when you choose it and go online with a nickname. An invitation must be accepted before a match starts. Nicknames are not verified identities; use one that does not contain personal information.

• PeerServer Cloud at 0.peerjs.com receives an identifier made from your nickname, your IP address and connection setup messages to find the other player. The identifier encodes your nickname; it does not hide it.
• Google's STUN service helps devices find a direct network route. Your network address is visible to this service and can be visible to the other player.
• Players exchange nicknames, invitations, racquet movement, ball and match state, scores, timing and connection status over an encrypted WebRTC connection. There is no game-data relay configured.

The developer does not operate a server that stores matches. Match state stays in memory for the session. Multiplayer results do not change your solo best score, and there is no chat, voice or video feature. Leaving multiplayer closes the connection.

PeerServer's privacy policy says connection information is held in memory while connected and removed after the default 60-second inactivity timeout. Network services handle information under their own policies; see Google's Privacy Policy for Google's services.

Keeping or deleting data

Local game information stays in the app until replaced or the app's data is deleted. Deleting the app can erase your score and preferences; offloading it may retain its data. Racquet does not provide online score recovery. Your iOS backup settings may also affect whether app data is retained in a device backup.

For questions or requests about information you sent directly to the developer, email kostakarathanasopoulos@gmail.com. For information held by a network service, use that service's privacy controls or contact process.

Support and this website

If you email support, the developer receives your email address and message and uses them to answer your request. Avoid sending sensitive information. Support messages are kept as needed to handle the issue and follow-up. GitHub issues are public and subject to GitHub's Privacy Statement.

This site is hosted by GitHub Pages, which receives visitor network information. The site has no advertising or analytics scripts. Opening a website from the app is separate from playing the game.

Children and changes

Do not send children's personal information through multiplayer nicknames or support. Contact the developer if you believe a child has provided personal information. Updated practices will appear here with a new date and any notice or consent required for the change.
