Blockmath privacy policy.

What this policy covers

This policy applies to Blockmath and the Tiny Proof Studio website. It describes the information handled by Tiny Proof Studio and by the third-party services used to operate and support the app and website.

If Blockmath adds another data-collecting service or a feature such as cloud save, this policy will be updated before that change is made available.

Information handled by this website

The current website does not offer user accounts, forms, payments, comments, or newsletters. Tiny Proof Studio therefore does not ask you to submit personal information through the site.

The infrastructure used to deliver the website may automatically process basic technical information—such as an IP address, browser or device type, requested page, and timestamp—for delivery, reliability, abuse prevention, and security.

Cookies and similar technology

Tiny Proof Studio does not use advertising or marketing cookies on the current website. The hosting layer may use strictly necessary security or session technology to operate and protect the site.

How technical data is used

Technical data is used only to deliver, maintain, secure, and troubleshoot the website, or to comply with a valid legal obligation. Tiny Proof Studio does not sell personal information or use website activity to build advertising profiles.

Limited technical information may be processed by the service providers that host and protect the website, subject to their own terms and privacy practices.

What the app stores and sends

On your device. Blockmath has no accounts and no sign-in. Your progress—solved levels, stars, coins, hints, undos, themes you own, your Daily Challenge streak, and your settings—is stored locally on your device. Uninstalling the app deletes it. If Android backup is turned on for your Google account, Android may include this data in your own device backup; Tiny Proof Studio cannot see that backup.

Usage analytics (Firebase Analytics). To understand how the game is played and improve it, Blockmath sends usage events to Google's Firebase Analytics, which Tiny Proof Studio can view in aggregate. These describe what happens in the game, for example: a level or Daily Challenge was started, completed or failed, how long it took, whether a hint or undo was used, coins earned or spent, ads shown, and store and purchase steps. Firebase also records information about the app and device, such as the app version, device model, operating system, language, approximate location (country or region, derived from your IP address), and identifiers such as an app instance ID and, where available, the advertising ID. Tiny Proof Studio does not receive your name, email address, contacts, or precise location.

Crash reports (Firebase Crashlytics). If Blockmath crashes or hits an error, a crash report is sent to Firebase Crashlytics so the problem can be found and fixed. A report contains technical details such as the error and where in the app it happened, the device model, operating system and app version, and an installation identifier.

Game settings (Firebase Remote Config). Blockmath downloads game settings, such as reward amounts and feature switches, from Firebase Remote Config. This uses a Firebase installation identifier and does not send your gameplay progress.

Ads (Google AdMob). Blockmath displays ads through Google AdMob using the Google Mobile Ads SDK. Google states that the SDK automatically collects and shares information including your IP address, interactions with the app and ads, diagnostic information, and device or account identifiers such as the advertising ID and app set ID. Google uses this information for advertising, analytics, and fraud prevention. Google's handling of this information is governed separately by Google's Privacy Policy.

Advertising consent. Where required—including in the European Economic Area, the United Kingdom, and Switzerland—Blockmath asks for your advertising choices before requesting ads. Depending on your choices and applicable law, Google may serve personalized, non-personalized, or limited ads. Non-personalized and limited ads may still involve data processing for ad delivery, measurement, security, and fraud prevention. Where this applies, you can review or change your choices from Settings → Privacy options.

Purchases (Google Play). Coin packs and Remove Ads are sold through Google Play. Google Play handles payment; Tiny Proof Studio never receives your card, UPI, or other payment details. The app receives Google Play's confirmation of a purchase so it can deliver what you bought, and sends purchase events (such as which product was bought and whether the purchase succeeded, failed, or was cancelled) to Firebase Analytics. Premium themes are bought with in-game coins, not with money.

Sharing your result. When you tap Share on a Daily Challenge result, Blockmath creates the image and text on your device and hands them to the app you choose. Nothing is sent to Tiny Proof Studio.

How this information is used. Analytics and crash information is used to run, maintain and improve Blockmath, to fix bugs, and to understand which levels and features work well. It is not sold, and Tiny Proof Studio does not use it to build advertising profiles. Firebase processes this data on Tiny Proof Studio's behalf under Google's terms; it is not linked to Google advertising products.

How long data is kept and how to remove it

• Progress on your device: until you uninstall the app or clear its data (Android Settings → Apps → Blockmath → Storage & cache → Clear storage).
• Firebase Analytics event data: kept for 2 months, then deleted automatically.
• Crash reports: kept by Firebase Crashlytics for up to 90 days.
• Ad-related data: governed by Google's Privacy Policy.

Because Blockmath has no accounts, Tiny Proof Studio cannot look you up by name or email. To ask for analytics or crash data from your installation to be deleted, email privacy@tinyproofstudio.com; we will explain how to identify your installation and delete what we hold.

Children's privacy

Blockmath is intended for a general audience aged 13 and older and is not directed to children under 13. The app does not offer account creation, sign-in, or features for submitting personal information to Tiny Proof Studio.

Tiny Proof Studio does not knowingly collect personal information from children. Google AdMob and Firebase may process information as described in section 05. If you believe a child under 13 has provided personal information to Tiny Proof Studio, or that information has been handled contrary to this policy, contact privacy@tinyproofstudio.com so the matter can be investigated and appropriate action taken.

Changes and contact

This policy may change as the website and Blockmath develop. The date at the top will be revised when material changes are published.
