Privacy Policy

Effective July 25, 2026; last updated August 8, 2026

This policy explains how Kaironos LLC ("we", "us", or "our") handles information when you use Rexaurus: Roar Arcade (the "Game"). Guest play is available without providing a name or email. Creating a protected account is optional.

1. Information we process

Guest and local game data

The Game stores progress, settings, accessibility preferences, dinosaur collection, cosmetics, homes, level results, and other gameplay state on your device. Guest play uses a random anonymous Firebase identifier so the Game can operate without requiring a personal profile.

Protected account data

If you choose to protect your Sanctuary, you may use a provider option shown in the Game when that option is enabled. Firebase Authentication processes the provider authorization and gives us an account identifier. We may receive limited account information that the provider and your settings allow it to share. Rexaurus does not use email-and-password authentication, and we do not receive your Apple or Google account password.

Cloud progress and transaction records

When cloud services are enabled, we process the account identifier and game state needed to sync progress across devices. This can include completed levels, stars, Adventure XP, Ember Coins, collection and cosmetic ownership, selected loadouts, homes, deterministic game-result identifiers, and server-side records used to prevent duplicate rewards or purchases.

Technical and security information

We and our providers may process app version, operating system, device type, IP address, request timestamps, security tokens, and device or app-attestation results. We use this information to authenticate requests, prevent abuse, investigate failures, and keep the Game reliable. The Game does not currently use a dedicated analytics or crash-reporting SDK.

Support communications

If you contact us, we receive your email address and the information you include in your message, such as a device model, account email, screenshots, or a description of an issue.

2. How we use information

• Provide local play, accounts, cloud sync, and restore.
• Validate level results and calculate durable rewards.
• Deliver purchases and prevent duplicate charges or grants.
• Serve, measure, and limit advertisements.
• Protect the Game, players, and backend from fraud or abuse.
• Respond to support, privacy, and deletion requests.
• Meet legal, tax, accounting, and app-store obligations.

3. Advertising

The Game uses Google AdMob for banner, interstitial, native, and optional rewarded ads. AdMob and its partners may process advertising identifiers, general device information, IP address, approximate location derived from IP, and ad interactions to deliver, secure, frequency-cap, and measure ads. Where required, the Game asks for consent through Google's User Messaging Platform before requesting personalized advertising.

Buying Ember Coins does not remove ads or change ad eligibility. The current release does not sell a subscription or Lifetime Pro entitlement. You can review available ad privacy choices from the Game's Account screen and through your device settings.

4. Purchases

Apple or Google processes payment. We do not receive your full card number or store password. RevenueCat processes purchase receipts, product identifiers, transaction identifiers, customer state, store account region, and related purchase events so the Game can reconcile Ember Coin purchases, refunds, and reversals. Consumable coin packs are not restorable store entitlements. Apple and Google retain their own transaction records under their policies.

5. Service providers

These providers process information under their own privacy terms and our applicable service agreements.

6. Sharing and sale

We do not sell personal information for money. We disclose information to the providers above only as needed to run the Game, fulfill purchases, serve ads, comply with law, or protect rights and safety. Some privacy laws may define personalized-ad processing as "sharing" or targeted advertising. Where applicable, use the Game's ad privacy choices or device settings to limit that processing.

7. Retention and deletion

Local data remains until you clear the Game's storage or uninstall it. Cloud account and progression data is retained while your account is active and as needed to operate sync, prevent duplicate value grants, resolve disputes, and meet legal obligations. We delete or de-identify data when it is no longer needed.

You can request deletion in the Game or follow our account and data deletion steps. Store-controlled purchase history and records required for legal, security, or accounting purposes may be retained by the relevant provider or for the period required by law.

8. Security

We use authenticated requests, encrypted network connections, server-side validation, idempotency controls, and app attestation. No system is completely secure, and we cannot guarantee absolute security.

9. Children

Rexaurus is a general-audience game. We do not knowingly collect personal information from children under 13, or under the applicable minimum digital-consent age, without appropriate authorization. If you believe a child provided personal information, contact us so we can review and delete it.

10. Your choices and rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to processing, and to appeal a privacy decision. You may play as a guest, decline optional account protection, review ad privacy options, review purchases through your app store, or delete your account. We will not discriminate against you for exercising a privacy right.

11. Changes to this policy

We may update this policy as the Game or its providers change. We will update the date above and provide additional notice when required.
