MindBolt Privacy Policy
1. Summary
MindBolt is a casual brain-training game. You can play without creating an account. If you choose to create one, we collect only what is needed to run it (section 3). We never ask for your contacts, photos, microphone or precise location.
2. Information stored on your device
To keep your progress between sessions, the app stores on your device:
- a random guest identifier generated by the app;
- the display name you choose (optional; "Guest Player" by default);
- XP, level, rank, personal bests, achievements, streaks, daily-challenge completion and a history of recent games;
- your settings (sound, haptics, reduced motion, daily reminder on/off and time);
- counters used to limit how often ads appear.
You can delete this at any time in Profile > Reset all data, or by uninstalling the app.
3. Optional account
If you create an account (with Apple, Google, Facebook or email and password), we store your email address, display name, sign-in method and a copy of your game progress in Google Firebase (Authentication and Cloud Firestore) so you can play on several devices. Email-and-password accounts receive a confirmation link by email.
We send account emails (confirmation, password reset and important service notices). We send tips, news, offers and occasional reminders when you have not played for a while only if you tick the marketing box when signing up. For those emails we share your email address, display name, level, rank, best streak and last-played date with our email provider, Brevo (Sendinblue SAS, France), and Brevo records whether the emails are opened. You can unsubscribe from any marketing email or by contacting us.
You can delete your account and its cloud data at any time in Profile > Delete account, or by emailing us.
4. Advertising
MindBolt is free and supported by ads from Google AdMob. When ads are shown, Google and its partners may collect your device's advertising identifier, IP address, approximate location derived from it, device and app information, and ad interactions, to serve, measure and personalise ads and to prevent fraud. Where the law requires consent (for example in the EEA, UK and Switzerland), the app asks for your choice through Google's consent tool before ads are requested; you can change it in Profile > Ad privacy choices. You can also reset or delete your advertising ID in your device settings.

Rewarded ads are always optional. Nothing you have already earned depends on watching an ad.
5. Analytics and crash reports
We use Google Firebase Analytics to understand how the games are played (for example which game was started or finished, scores, session length and ad events) and Firebase Crashlytics to receive crash reports (device model, operating-system and app version, and technical details of the error). These use an app-instance identifier, not your name or contact details.
6. Notifications
Notifications are off until you turn on Profile > Daily reminder (or accept the offer after a game); only then does the app ask your device for permission. Daily reminders are scheduled on your device and skipped on days you have already played. When reminders are on, your device also receives occasional news about new games and challenges through Google Firebase Cloud Messaging, which uses a device token, not your name or contact details. Turn reminders off in Profile, or turn off notifications for MindBolt in your device settings, to stop both.
7. Sharing
We do not sell your personal information. Data is processed by Google (Firebase and AdMob) and, for marketing emails you opted in to, Brevo as our service providers, and by Facebook or Apple only if you choose to sign in with them. We may disclose information if required by law.
8. Children
MindBolt is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has created an account, contact us and we will delete it.
9. Retention and security
On-device data stays until you reset it or uninstall the app. Account data is kept until you delete your account. Data processed by Google is retained under Google's policies. When you delete your account we also remove you from our email provider. Data is encrypted in transit. Cloud progress can be read only by the signed-in account owner and by authorised Datacraft Interactive staff, who use it to run and support the game.
10. Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, or to object to or restrict its processing. Email datacraftinteractive@gmail.com and we will respond within 30 days.
11. Changes
We will update this policy when our practices change and revise the date above. Significant changes will be announced in the app.
