Privacy Policy

Last updated: May 5, 2026

This Privacy Policy applies to mobile applications published by Mindforge Studios:

Short version: Almost everything stays on your device. We do not sell your data and we do not target advertising at you based on personal information. Each app collects only what is needed for the features you actually use; the per-app summary is in section 2.

1. Principles that apply to every app

Important: if a particular feature (advertising, analytics, in-app purchases, cloud sync, multiplayer, etc.) is not listed for an app in section 2, it is not present in that app's current release. When we add such a feature, we update this policy and the app's release notes before publishing.

2. Per-app summary

DigitSpan

What we send to our serverAnonymous device UUID generated locally on first launch, a randomly assigned nickname (e.g. "Calm Lynx"), best digit span, best session points, total points. Optionally a push token if you enable daily reminders.
What we do not useNo advertising, no analytics SDK, no in-app purchases, no Firebase Analytics, no third-party trackers. The app does not request microphone, camera, location, contacts or storage permissions.
WhyLeaderboards: so the rankings screen is not empty. Push token: only if you turn on reminders in Settings.
AccountThe app does not require any account. A future Google Sign-In integration is partly prepared in code but is not exposed in the user interface in the current release.

Blast Quest

What we send to our serverDuring an online multiplayer match: your chosen display name, in-match position, actions and scores. After the match ends, in-match telemetry is discarded; only the final score is retained for ranking purposes.
CommunicationNo text or voice chat. Players interact only through gameplay.
AccountMultiplayer can be played without creating a persistent account.

All other apps in the list above

The other apps listed in the introduction store data on your device only and do not transmit personal data to our servers. They follow the principles in section 1. If we add cloud features (leaderboards, sync, multiplayer) to any of them, this section will be expanded with a per-app summary before the change is shipped.

3. Notifications

If you enable push notifications inside an app, that app schedules local reminders on your device and may register an anonymous push token with our server so we can deliver streak/training alerts. You can disable notifications at any time in app settings or in your phone's system settings. Notifications are never used for marketing.

4. Children

Our apps are designed to be safe for general audiences and we do not knowingly collect personal information from children under 13. Core functionality works without an account and most data stays on the device.

5. Server logs

Apps that talk to our backend cause standard nginx access logs (IP, timestamp, request path) to be written for security and debugging. Logs are retained for 30 days and are not joined with the anonymous user records described in section 2.

6. Third parties

Our apps rely on the following platform components, which we do not operate:

7. Data deletion

Your local data is removed when you uninstall the app.

To delete the anonymous record we may keep on our server (nickname + scores + push token), please send an email from any address to hello@nextlevelwork.ru with the subject line DELETE and:

Because the records are anonymous, the nickname is the only way for us to find your data. We anonymize the matching record within 14 days and confirm by email.

8. International users

Our servers are located in the Russian Federation. By using our apps you understand that any anonymous record described in section 2 may be processed there. The data described above does not include personally identifying information.

9. Changes

If this policy changes materially, we update the date at the top of this page and mention the change in the affected app's release notes. Continued use of an app after such an update means you accept the updated terms.
