Block Defenders Privacy Policy

Last updated: October 15, 2026

Block Defenders is a village-building and block puzzle game developed by MMB Software (Android, package name com.mmbsoftware.mathris). This page explains what data the game uses and how, and what your rights are.

Data controller: MMB Software · mmbsoftware.dev@gmail.com

1. Data stored on your device

Your village, army, progress and settings are stored only on your own device. They are not sent to our servers. Uninstalling the app deletes them.

2. Data we do not collect

The game has no account, login or sign-up. We do not collect your name, email address, phone number, location, contacts, photos or files.

3. Google services we use

To offer the game for free and improve it, we use the following services:

• Google AdMob (ads): Processes data such as the advertising ID, device information and IP address to show ads. Players in the European Economic Area, the United Kingdom and Switzerland are asked for consent before personalized ads; this choice can be changed in the game under Settings → Privacy → Privacy Options. You can reset or delete your advertising ID in your device's Settings → Google → Ads.
• Firebase Analytics (usage statistics): Collects game events (e.g. a round ending, an expedition starting, a rewarded ad being watched), device model, operating system and app version to understand how the game is played. This data is not used to identify you.
• Firebase Crashlytics (crash reports): Sends a crash report and device information when the game crashes so we can fix the problem.
• Google Play Billing: The "Remove Ads" purchase is made through Google Play. Your payment details never reach us.

How these services process data is described in Google's privacy policy: policies.google.com/privacy. Your data is not sold and is not shared with anyone other than the services above. All transfers use encrypted connections.

4. Notifications

The game may send local notifications, for example when a building is finished or a raid is approaching. They are scheduled on your device; no data is sent to a server for them. You can turn notifications off in the game's settings.

5. Children

The game is not directed at children under 13 and does not knowingly collect personal data from children under 13.

6. Data deletion and contact

To request deletion of your Firebase and AdMob data, or for any question, write to mmbsoftware.dev@gmail.com with the subject "Block Defenders – Data Deletion Request". We reply within 30 days.

7. Changes

When this policy is updated, the new version is published on this page and the date above changes. For MMB Software's general privacy policy see: Privacy Policy.
