Block Daily — Privacy Policy

Last updated: November 7, 2026

This policy covers Block Daily, the block puzzle app for Android published by Kallistesoft. In short: there is no account, we collect no personal information ourselves and there are no analytics. Ads are served by Google AdMob, the optional "No ads" purchase goes through Google Play, and the app uses Firebase to check for updates, report crashes and run the shared leaderboards. This page explains what each of them processes.

1. Data kept on your device

Your scores, daily results and streak, games in progress, sound setting and whether you bought "No ads" are stored on your device. Apart from the scores that make a leaderboard (section 7), they are not sent to us. They are deleted if you uninstall the app or clear its data.

2. Advertising (Google AdMob)

Block Daily shows ads served by Google AdMob (Google Mobile Ads SDK): a full-screen ad between games (never during play, at most one every 90 seconds), an optional video you can choose to watch to continue a game, and a banner under the pieces. Ads for alcohol, gambling, dating and sexual content are blocked.

To show and measure ads and to prevent fraud, Google may collect:

This processing is Google's responsibility. See how Google uses information from sites or apps that use its services and Google's Privacy Policy.

3. Your choices and consent

Where the law requires it (European Economic Area, United Kingdom, Switzerland and some US states), Google's consent platform asks for your consent at launch. You can change your choices at any time with "Privacy options" on the home screen. On Android, you can also reset or delete your advertising ID in the device settings (Google › Ads).

4. "No ads" purchase (Google Play)

The optional one-time "No ads" purchase is processed entirely by Google Play under Google's Privacy Policy. We never receive your payment details; the app only learns whether the purchase was made, and stores that on your device.

5. App settings (Firebase Remote Config)

At launch, Block Daily checks whether an update is required or recommended through Firebase Remote Config. This request carries a Firebase installation ID (random, unique to each install, separate from the advertising ID and not linked to your identity) and your IP address. This data is used only to run the app.

6. Crash reports (Firebase Crashlytics)

If Block Daily crashes, Firebase Crashlytics sends us a crash report: the error and where it happened in the code, the app version, device model and operating system version, a Firebase installation ID (random, not linked to your identity) and your IP address. We use these reports only to find and fix bugs. They contain no scores, no game content and nothing that identifies you.

7. Leaderboards (Firebase)

The home screen shows the top 3 scores of all players: classic today, classic all time and today's daily challenge. When one of your scores can enter one of these top 3s, the app stores it in Firebase Cloud Firestore together with a random anonymous ID created by Firebase Authentication. There is no name, email or account, and other players see only the score numbers, never your ID. The anonymous ID also lets the app show a medal next to your own scores.

To keep fake scores out, Firebase App Check asks Google Play Integrity to confirm that requests come from the genuine app installed from Google Play; this check is processed by Google. Leaderboard scores are kept so the boards can be shown. Uninstalling the app or clearing its data gives you a new anonymous ID; to have a stored score deleted, contact us (section 11).

8. Sharing results

When you tap "Share", the app prepares a short text (your daily score, combo and streak) and opens your device's share menu. Nothing is sent without your action, and you choose who receives it.

9. Children

Block Daily is family-friendly but intended for a general audience, not directed at children under 13. We do not knowingly collect personal information from children. The "No ads" purchase is protected by a grown-up check in the app and by Google Play's purchase authentication. If you believe a child has sent us information, contact us and we will delete it.

10. Your rights

Depending on where you live (including Québec under the Act respecting the protection of personal information in the private sector, elsewhere in Canada, and the European Union), you can ask to access, correct or delete your information, and withdraw your consent. Since we keep no data about you beyond anonymous leaderboard scores and our email exchanges, most such requests concern Google for advertising, purchases and Firebase; we'll gladly help you make them.

11. Contact and person in charge of the protection of personal information

For any question, request or complaint about your personal information: contact@kallistesoft.ca. If you write to us, we use your email address only to reply, and delete the exchange once it is no longer needed. You may also contact the Commission d'accès à l'information du Québec or the Office of the Privacy Commissioner of Canada.

12. Changes

We will update this page if Block Daily's practices change. The date at the top shows the latest revision. Policies for Kallistesoft's other apps and website: kallistesoft.ca/en/privacy.
