In short: Brain Games works offline and has no ads, analytics or accounts. Your scores never leave your phone. The app connects to nowstacks.com only to check for updates and to send feedback or crash reports when you choose to.
Brain Games: Train Your Mind (package com.gauravkr.braingames, "the app") is published by NowStacks (nowstacks.com; "we", "us") and developed for us by our development partner, Gemini Digital Solutions. This policy explains how the app handles your information.
1. Information we collect
The app does not require an account and does not collect your name, location, contacts or photos. We receive information only in the situations described in section 3 — an automatic update check, and feedback or crash reports that you choose to send (an email address is included only if you type one).
2. Information stored on your device
Your best scores are kept in the app's memory only while you play — they are not saved and never sent anywhere. The app saves only a few preferences on your device: your crash-report choice, whether you postponed an update, how many times the app has been opened (used to show the rating prompt once) and, only until they are sent or you decline, up to five crash reports waiting to be sent (section 3). The app is excluded from Android cloud backup, and this data is deleted when you clear the app's data or uninstall it.
3. Update checks, feedback and crash reports
The app connects to nowstacks.com, our own server, only for these features:
- Update check — when you open the app, it asks nowstacks.com whether a newer version is available, so it can tell you when an update is recommended or required. The request contains only the app's package name and version and, like any internet request, your IP address.
- Feedback and ratings — only if you choose to send feedback (Rate & feedback or Report a problem). We receive your star rating, your message and, only if you type it, your email address, together with the app version, Android version, device model and language.
- Crash reports — if the app closes unexpectedly, it asks you before sending a crash report, unless you chose to send them automatically (you can change this choice in the app's settings). A report contains the technical error details, the app version, Android version, device model, language and any comment you add. It does not include your documents, files, photos, game data or other personal content — although, rarely, a technical error message can quote a small piece of the data the app was handling when the error happened.
We use this information only to reply to you, fix problems and improve the app. It is stored securely on nowstacks.com's infrastructure (our database and hosting providers process it on our behalf), is never sold, and is never shared with advertisers or other third parties. A one-way hashed (non-reversible) form of your IP address is stored with feedback and crash reports only to prevent spam. We delete feedback and crash reports when they are no longer needed, and you can ask us to delete anything you sent at any time (see "Contact").
4. Third-party services
The app contains no advertising, analytics or social-media SDKs. Crash reports and feedback go only to our own server, nowstacks.com, as described in section 3.
5. Permissions
| Permission | Why |
|---|---|
| Internet | Update checks, and feedback and crash reports you choose to send (section 3) |
6. Children
The app is suitable for all ages. We do not knowingly collect personal information from children under 13; the only information the app sends is described in section 3, and a child should not type an email address into the feedback form without a parent's help.
7. Your rights
Your scores stay on your device under your control. To access or delete feedback or crash reports you sent us, or for any question under a privacy law, contact us.
8. Changes
If this policy changes, the updated version will be published on this page with a new "Last updated" date.
