SonicCarrom Privacy Policy

Last updated: 3 November 2026

SonicCarrom is an accessible carrom game by AtheeTech for Android and Windows, playable offline against the computer and online against other players, with full voice guidance for blind and low-vision players. This policy explains what information the apps collect, why, how long we keep it, and the choices you have.

Information we collect

Your account (only when you sign in)

• Google account details: when you sign in with Google we receive your account ID (uid), name, email address and profile picture. We use them to identify your player profile, show your name to opponents, and link your purchases and statistics to you.
• Game data: your online match results, scores and statistics (matches played, won and lost, queens covered), your match history and your online rating.
• Purchases and subscription state: if you buy SonicCarrom Premium, Google Play handles the payment. We receive and keep the product, the Google Play purchase token, whether the subscription is active, its expiry date and whether it renews automatically. We never see your card or payment details.

Usage and diagnostics (also before you sign in)

• Install ID and session IDs: a random ID created when the app is installed, and a random ID for each time you open the app. They are not derived from your device, phone number or advertising ID. When you are signed in they are linked to your account.
• Device information: device model and manufacturer, operating system and version, language and region setting (locale), time zone, screen size, memory (RAM), app version, whether a screen reader (TalkBack or NVDA) or the app's accessibility mode is on, and which text-to-speech engine is used. On Windows also the processor type and number of cores.
• App activity and feature use: which screens you open, onboarding steps, settings you change, which features you use (for example aim assist, board exploration, quick chat or voice chat), the outcome of sign-in, permission and purchase screens, lobby events, and app updates.
• Match statistics: for games against the computer and online, the mode, game type, computer opponent and difficulty, result, duration, strokes, fouls, coins pocketed and scores, plus a sample of shots (power, angle, result).
• Crash logs and diagnostics: when the app crashes or hits an error, the error message and type, the stack trace, the screen or room it happened in, and breadcrumbs (the last few app events before the error, of the kinds listed above).
• Network error diagnostics: which server call failed, its status, the reason and how long it took.
• Performance metrics: for example dropped frames, physics and speech timing, and connection round-trip time.
• Server records: our game server records each request it handles (which function, the result, how long it took, your account ID if signed in, platform and app version) to keep the service running and find faults.
• Coarse location: the country your connection comes from, as reported by our network provider. We do not store your IP address and do not collect precise location.

Online play

• Lobby and chat messages: messages and quick-chat phrases you send in a game room are delivered to the other players in that room. They are kept only while the room exists and are deleted when the room is cleaned up (normally within a few hours).
• Voice chat: voice chat is optional and starts only when both players turn it on. Audio is sent encrypted directly between the two players' devices, or through a relay server when a direct connection is not possible. We do not record or store voice audio.
• Network information: your IP address is used while you are connected, to connect players directly during a match, to relay voice when needed, and to protect the service against abuse (rate limiting). It is not written to our database, and it is not used for advertising or to locate you. Our hosting provider (Cloudflare) may process it in its own short-lived security and request logs.
• Fair-play and device checks: to keep online games fair, the server checks reported results and keeps a record of suspicious results or disputes, linked to the players' account IDs. On Android we ask Google Play Integrity whether the app and device are genuine and keep the result; on Windows the app registers a random device ID with the server.
• Notification token: if you allow notifications, the app registers with Firebase Cloud Messaging so we can send game announcements and messages meant for you.

Tester program (only if you apply)

• Tester application: when you apply to test SonicCarrom we keep your account ID, email address, the name and country you enter, the platforms you want to test on (Android, Windows), and what you tell us about your device, screen reader, vision and how you heard about us. If you came from our Telegram group, also your Telegram user ID and username, so our Telegram bot can welcome you and send you the tester links. We use this only to run the tester program.

On your device only

• Settings: your game preferences (sound, accessibility and gesture settings) are stored on your device, encrypted.

Why we use it

• Running the service: sign-in, online matches, lobbies, chat, voice, ratings, purchases and notifications.
• Fixing bugs: crash logs, diagnostics, network errors and server records show us what went wrong, and on which devices and versions.
• Analytics: usage, match statistics, device and performance information tell us which features are used, how well the game works with different screen readers and speech engines, and what to improve. We look at this ourselves; it is not shared.
• Fair play and integrity: preventing cheating, modified apps or devices, and abuse of the online service.

What we do not do

• We do not sell your personal information, and we do not share it for advertising.
• No advertising, and no advertising or tracking identifiers.
• No third-party analytics, crash-reporting or advertising SDKs: usage and crash reports go only to SonicCarrom's own server.
• No precise location, contacts, photos or files from your device.
• No voice recordings.

Microphone

The microphone is used only for voice chat during an online match, only after you turn voice chat on, and only while the call is active.

Services we use

• Google Firebase (Google LLC): sign-in, player profile storage, app updates, push notifications, and storage of our nightly database backups.
• Google Play (Google LLC): payments and subscriptions, and Play Integrity checks on Android.
• Cloudflare (Cloudflare, Inc.): game servers for online matches, lobbies and chat, the voice relay, and the database that holds game data, usage and diagnostics.

These providers process data on our behalf under their own privacy and security terms, and may store it outside your country. Data is encrypted in transit (HTTPS / TLS, and DTLS-SRTP for voice). Only the developer can see the collected data, through a private admin page that requires the developer's Google sign-in.

How long we keep data

• Your profile, game statistics, rating and purchase records: while your account exists.
• App activity events and sessions: 90 days.
• Server request records: 30 days.
• Crash and error reports: grouped by error. A group is kept until the problem is resolved; individual reports (with device details and breadcrumbs) are deleted after 90 days, except the latest few of each group.
• Install records (install ID and device information): while the app is in use; they are linked to your account when you sign in.
• Game rooms, matches and chat messages: deleted automatically when the room is cleaned up, normally within hours.
• Fair-play records: up to 12 months.
• Tester applications: while the tester program runs, or until you ask us to delete them.
• Backups: a copy of the database is made every night and each copy is deleted after 30 days, so deleted data also leaves the backups within 30 days.

Your choices and deleting your data

• Usage and crash reports are part of how the game works and cannot be turned off in the app: we rely on them to find and fix bugs, especially accessibility problems. They never contain chat text, and you can ask us to delete them (below).
• You can play offline against the computer without signing in.
• You can turn off notifications and voice chat at any time in the app or in your device settings.
• To delete your account and its data, or only some of it, follow the steps on the account deletion page. We delete it within 30 days, including the usage and diagnostics linked to your account and its installs.

Children

SonicCarrom is intended for players aged 13 and over. We do not knowingly collect personal information from children under 13. If you believe a child has given us information, contact us and we will delete it.

Changes to this policy

If we change this policy we will update the date above, and for important changes we will tell players in the app.
