Privacy Policy

1. What we collect

• Account identity (email, Google profile) stored in our Postgres via Better Auth.
• Profile fields: username, display name, avatar URL.
• Custodial wallet addresses, public keys, and encrypted mnemonic material per supported chain. Balance is read from the network; we do not keep an internal ledger.
• Match history, stats, lobby participation, Redis vault drafts, and Web Push endpoints.
• IP addresses and application logs for abuse control.

2. Why we use it

To run accounts, matches, anti-abuse, payouts, and notifications you enable. We do not sell personal data.

3. Processors

Neon (database and Auth), Google (OAuth if you use it), the Stacks and Solana networks and their RPC providers, and browser push services (Apple, Google, Mozilla, and similar).

4. Retention and rights

We keep account and match records while the account is active. After deletion we scrub profile PII, drop push subscriptions and wallet ciphertext, and keep anonymized match rows so other players’ history still resolves.

You can access or delete your account from Settings, subject to funds and active-match checks. Contact legal@mail.stackswars.com or Telegram.

5. Cookies and local storage

We use session cookies for sign-in, plus local storage for sound preferences, install-prompt dismissal, and similar client settings.

6. Children

The service is not for anyone under 18. We do not knowingly collect data from children.
