Privacy Policy — Munchain

Last updated: 20 June 2026

This Privacy Policy explains how Munchain ("the Game", "we", "us") handles your information. The Game is developed by Lewa ("the Developer"). By playing Munchain you agree to this policy.

1. Information We Collect

Munchain does not require you to create an account with personal information. We do not collect your name, email, phone number, or precise location.

• Anonymous account ID: created on first launch (Supabase anonymous authentication) to save progress and rankings; not linked to your real identity.
• Gameplay data: scores, league points, match history, duel results, and the move history of competitive matches (used to verify scores and prevent cheating).
• Username: an optional display name you may set (auto-generated by default), shown on leaderboards.
• Analytics events: anonymous usage events (e.g. app opened, game started, match finished) to improve the Game. No personal data.
• Advertising identifier & device data: to show ads, Google AdMob may access your device's advertising ID (AAID) and limited technical/device information (e.g. device type, OS version, coarse region). See "Advertising" below.

2. How We Use Information

• Save and sync your game progress.
• Operate leaderboards, leagues, and duels.
• Verify match results and prevent cheating.
• Analyze aggregate usage to improve the Game.
• Display advertisements that help keep the Game free.

We do not sell your data.

3. Third-Party Services

• Supabase (database & authentication) — supabase.com/privacy
• PostHog (anonymous product analytics) — posthog.com/privacy
• Google AdMob (advertising) — serves ads and processes the advertising ID and device data described above. How Google uses data · Google Privacy Policy

4. Advertising

Munchain is free and supported by ads served through Google AdMob:

• Rewarded ads are optional — they only play when you choose to watch one (e.g. to double a reward).
• Interstitial (full-screen) ads may appear occasionally between games.

We request non-personalized ads (ads are not based on a profile of your interests). Even so, AdMob may use your advertising ID and device data for purposes such as ad delivery, frequency capping, and fraud/abuse prevention, as described in Google's policies above. Ad content is limited to a maximum rating of PG, and the Game is not directed to children. You can reset or limit your advertising ID at any time in your device settings (Settings → Privacy / Google → Ads).

5. Data Retention & Deletion

You can delete your account and all cloud data at any time: in the game go to Settings → "Delete account & data." You may also request deletion by email at sarialemirhan0@gmail.com.

6. Children

Munchain is not directed to children under 13 and is intended for ages 13+. We do not knowingly collect personal information from children, and ads are configured as non-personalized and limited to PG content.

7. Security

Data is transmitted over HTTPS and protected by database access controls (row-level security).

8. Changes

We may update this policy; the "Last updated" date reflects changes.
