Privacy Policy
Last updated: September 2026 • Mind Mystery
1. Introduction
Mind Mystery ("the app") is a mentalism and entertainment performance tool. It includes features such as Number Revelation, Card Reading, Emotion Reading, Hidden Time, Secret Word, Mental Notes, Canvas Predict Pro, Forcing (ChronoStop and CardStop), Calculator Pro, My Routines Vault, and related performance aids. All effects are illusion-based entertainment for performance purposes only; the app does not provide genuine psychic, supernatural, or paranormal abilities. This policy describes how we handle information when you use the app. We do not sell your personal data. By using the app, you agree to this Privacy Policy.
2. Information we collect
The app stores minimal data locally on your device only:
your preference for showing or hiding instructions and guide buttons inside each act,
whether you have completed your first use of performance acts,
whether we have already shown you a rating prompt,
your favourite acts shortcut list,
the app version for which you last viewed the What's New screen,
Mental Notes settings (such as Type/Draw mode, dual prediction, and peek preferences) and session content,
Canvas Predict Pro settings, touch map configurations, Dark Mode canvas preferences, guided practice state, and custom drawing predictions,
My Routines Vault routine notes, scripts, tags, and readiness status,
ChronoStop and CardStop performance settings (such as prepared force values),
Calculator Pro settings, force presets, workflows, and a short local peek history used during performance, and
optional one-time UI prompts (for example community invite).
All notes, predictions, drawings, and settings are stored only on your device, are not uploaded to our servers, and can be cleared from within the app or by clearing app data. If you make an in-app purchase (Secret Word, Mental Notes, CardStop, Calculator Pro, or Canvas Predict Pro), the purchase unlock flag is stored locally using encrypted storage where supported. We do not collect your name, email address, phone number, or precise location.
3. Push notifications (Firebase Cloud Messaging)
The app may use Firebase Cloud Messaging (FCM), a Google service, to deliver optional push notifications such as updates, tips, and announcements. To send notifications, Google/Firebase may process a device push token and related delivery metadata. Notification permission is requested on supported Android versions; you can deny or later revoke it in system settings. Firebase's processing is governed by Google's privacy policy. You can stop receiving notifications by disabling notification permission for the app or by uninstalling the app.
4. Audio instructions and Calculator Pro audio
Some instruction and paywall screens offer an optional audio guide that reads text aloud using your device's built-in Text-to-Speech (TTS) engine. Calculator Pro may also use local TTS (for example earbud whisper/readout modes) to speak digits or peeked values during a performance. Speech is generated and played locally on your device. We do not record, transmit, or store audio, voice data, or the text being read on our servers.
5. Ratings on Google Play
The app may invite you to rate Mind Mystery on Google Play after completing a performance. Tapping Rate Us opens the app's Google Play listing in your browser or the Play Store app. Any rating or review you submit is processed and stored by Google Play, not by us. Submission is entirely voluntary. Google Play's privacy policy governs any data you submit on their platform.
6. In-app purchases
In-app purchases (Secret Word, Mental Notes, CardStop, Calculator Pro, and Canvas Predict Pro) are separate one-time purchases processed by Google Play. We do not receive or store your payment details. The purchase unlock state is saved locally on your device. Restore of purchases follows the standard Google Play restore flow.
7. Internet and network use
The app may use an internet connection to:
load and cache fonts for display,
launch external links (e.g. the Magic Shop, social media, or the Google Play store page),
communicate with Google Play Billing for purchases and restore, and
communicate with Firebase Cloud Messaging for optional push notifications.
The app does not use Firebase Analytics or any other analytics service. External links open in your browser or another app and are governed by the privacy policies of those services.
8. Third-party links and services
The app may link to or rely on external websites and services (e.g. the Magic Shop, Instagram, YouTube, WhatsApp community invites, Google Play, and Firebase/Google for messaging and billing infrastructure). Those sites and apps have their own privacy policies and terms. We are not responsible for their practices.
9. Data retention and deletion
Data stored on your device is kept until you uninstall the app or clear the app's data (Android: Settings → Apps → Mind Mystery → Storage → Clear data). Local Calculator Pro peek history and Mental Notes session content can also be cleared from within the app. We do not retain any personal data on our servers. The app does not use analytics services that collect or retain usage data.
10. Third-party names and trademarks
The app may refer to or list names of persons, brands, or products for identification purposes only. All trademarks and names are the property of their respective owners. No affiliation or endorsement is implied.
11. Security
We do not store your performance content on our servers. Local preferences and purchase unlock flags are stored on your device, using encrypted storage where available. No mobile app can guarantee absolute security. You are responsible for the security of your device, especially when spectators interact with it during a performance.
12. Children's privacy
The app is intended for general audiences as an entertainment and performance tool. It is not directed at children under the age of 18. We do not knowingly collect personal information from minors. If you believe a minor has provided personal information, please contact us and we will take steps to address it.
13. Your rights and choices
You have the right to access, correct, and erase data stored about you. You can adjust your in-app preferences at any time from the Settings screen, revoke notification permission in system settings, and uninstall the app or clear app data to remove locally stored data. For any data-related requests or concerns, please contact us at visualmagix10@gmail.com.
14. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the app after any changes constitutes acceptance of the updated policy.
15. Contact us and grievance redressal
For privacy-related questions, data requests, or to raise a concern, please contact us at: visualmagix10@gmail.com. You may also reach us via the Magic Shop at https://visualmagixshop.in. We will respond within 30 days.
16. Google Play distribution
This app is distributed via Google Play. The privacy practices described in this policy apply to the app regardless of where it is downloaded. Google Play's own data practices are governed by Google's privacy policy. The app does not use Firebase Analytics or any third-party analytics SDK. Play Console Data safety answers should reflect: local storage only, in-app purchases, optional push notifications, and no data shared with third parties.
