TileBuddy is a Hong Kong Mahjong companion app for scoring, reference, and AI-powered tile recognition. We respect your privacy and collect minimal data.
TileBuddy requests camera access solely for the Hand Scanner feature, which photographs mahjong tiles for AI-powered recognition. Camera access is only activated when you explicitly open the scanner. Photos are not stored permanently on your device or on any server.
When you use the Hand Scanner, the captured image is sent to the Google Gemini API (via a secure server-side proxy) for tile identification. Google processes this image according to their own privacy policy. Images are not stored on our servers.
Game settings, player names, and scoring history are stored locally on your device using your browser's built-in storage. This data never leaves your device and is not transmitted to any server.
TileBuddy does not collect, store, or transmit any personally identifiable information. Player names entered in the app are stored only on your device.
TileBuddy uses PostHog to collect anonymous usage data, such as which features are used and error reports for stability improvements. We have configured PostHog to:
Analytics data is used solely to understand feature usage and improve app stability. No advertising networks or tracking technologies are used.
TileBuddy does not currently require or offer user accounts. There are no in-app purchases or subscriptions.
TileBuddy does not knowingly collect information from children under 13.
We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
