This Privacy Policy describes how Brain Box Puzzle ("the App", "we", "us") collects, uses, and protects information when you use the App. Brain Box Puzzle is a mobile puzzle game developed by Mobylex. By using the App, you agree to the collection and use of information in accordance with this policy.
Brain Box Puzzle does not have user accounts, sign-in, cloud save, or leaderboards. We do not ask for your name, email address, or any other contact details inside the App.
| Category | What it is | Where it is kept / why |
|---|---|---|
| Game progress | Solved levels, best move counts and stars, the position of a level you have not finished, and your remaining hints. | Stored only on your device, so you can continue where you left off. It is never sent to us. |
| Settings | Sound, music, language and theme choices, and when the "rate this game" question was last shown. | Stored only on your device, to remember your preferences. It is never sent to us. |
| Purchase history | Which in-app products (Premium, hint packs) you have purchased. | To deliver and restore the items you bought. We never see or store your payment card details — all payment processing is handled by the Apple App Store or Google Play Billing. |
| Advertising identifiers | Your device's advertising ID (Google Advertising ID / Apple IDFA) and related ad-request data, collected by Google AdMob. On iOS, the IDFA is only available if you allow tracking when asked. | To show and measure ads: short ads between levels (not shown with Premium) and optional rewarded video ads you can choose to watch for a free hint. |
| Ad consent choices | Your answers to the privacy/consent message shown by Google's User Messaging Platform (shown to users in the EEA, the UK and other regions where required). | To respect your choices about personalized ads. Stored on your device by Google's SDK. |
We do not collect your location, contacts, photos, microphone/camera input, browsing history, or health data. Brain Box Puzzle does not contain chat, messaging, or any way to exchange content with other users.
The App uses the following service providers to operate its features. They process data on our behalf and are not permitted to use it for their own independent purposes, except as described in their own privacy policies:
Brain Box Puzzle does not use analytics/attribution SDKs or crash-reporting SDKs, and does not sell or share your data with data brokers. Google AdMob may use your device's advertising identifier to select, deliver, and measure ads, and to help prevent the same ad from repeating; this is governed by Google's own privacy policy linked above.
We do not share your personal data with third parties for their own marketing purposes. Apart from the advertising data handled by Google AdMob and the purchase data handled by Apple / Google as described above, no data leaves your device.
Because your game progress and settings are stored only on your device, uninstalling the App deletes them. We do not keep a copy. Purchase records are kept by Apple or Google under their own retention rules, which lets you restore Premium on a new device with Shop → Restore Purchases. Advertising data is retained by Google according to its privacy policy linked above.
The App communicates with Google AdMob and the app stores over encrypted connections (HTTPS). However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.
Brain Box Puzzle is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will delete it promptly.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
