Privacy policy

Last updated: September 22, 2026

SemiCircleGame has no server of its own: a game is played directly between the players' devices or, for online play, through Game Center, Apple's service. We do not collect, receive or host any personal data.

No data collection

We run no server and never receive anything from your device:

• we ask for no account, no identifier and no email address (online play uses your Game Center account, managed by Apple);
• no analytics, no advertising, no trackers;
• games, rounds and scores are saved nowhere: they live in memory for the duration of the game;
• your only persistent data — your nickname and whether you have seen the tutorial — stays on your device.

Exchanges between players

During a game, the players' devices exchange:

• your nickname (the one picked on the home screen), to label the room and the scores — and online, your Game Center identifier, to tell players apart;
• game data: the drawn theme, the target position, the guess, the scores and the round flow;
• the nearby link uses Core Bluetooth and is not encrypted: a device within range could, in principle, read this game data;
• online, these exchanges go through Apple's Game Center servers, under Apple's privacy policy; none go through a server of ours, and we keep nothing after the game;
• while your Bluetooth room is open, your nickname is visible to nearby devices looking for a game.

Device permissions

The game asks for only two permissions, solely to play nearby:

• Bluetooth — to link your device with the other nearby players' devices, up to 4 players.
• Local network — to discover the other players' nearby devices and establish the direct connection with them. No other permission (camera, photos, location…) is requested.

Data retention

Your nickname and preferences stay on your device for as long as the game is installed; uninstalling the game erases them. Games themselves are never saved.

No third parties besides Apple

SemiCircleGame includes no analytics, no advertising, no trackers and no third-party SDKs. Only Game Center, Apple's service built into iOS, is used, for online play. Your data is never sold or shared with third parties. The web pages you are reading here are likewise served without cookies or tracking.

Your rights

Since we hold no data about you, you exercise your rights directly on your device:

• Access and rectification — your nickname can be viewed and changed at any time from the home screen.
• Erasure — uninstalling the game erases all local data (nickname and preferences).
• Complaint — you may lodge a complaint with the French data protection authority, the CNIL (cnil.fr).

Security

The Bluetooth link between devices is not encrypted, so that joining a game never asks you to pair the phones. It only carries game data: nicknames, themes, answers and scores. Online, exchanges go through Apple's Game Center infrastructure. Your preferences benefit from iOS system protections: app sandboxing and device encryption.

Changes

This policy may be updated if the game evolves. The date above indicates the latest version.
