Privacy Policy
The short version. Stackfall Blocks saves your game progress and leaderboard scores to Google Firebase so you can restore them and compete with other players. The name you choose appears on public leaderboards. Ads are served by Google AdMob, which uses your device's advertising ID. You can delete your account and all of its data at any time in Settings → Delete account. We never sell your personal information.
This policy explains what information the Stackfall Blocks mobile game (“the game”, “we”, “us”) collects, why, who it is shared with, and the choices you have. The game is made by Abrar Amin, an independent developer, who is responsible for your data.
1. Information we collect
Information you give us
- Player name. The name you choose when you first play. It is shown publicly on the leaderboards. Please don't use your real full name if you'd rather not.
- Email address and password (optional). Only if you use Save your progress in Settings to protect your progress with an account. Passwords are handled by Firebase Authentication; we can never see them.
Information created as you play
- Account ID. A random anonymous ID that Firebase Authentication creates the first time you open the game, so your progress belongs to you without a sign-up.
- Game progress and settings. Coins, best scores, recent scores, Adventure levels and stars, Daily puzzles solved, themes owned, whether you bought Remove ads, games played, lines cleared, and your sound and vibration settings. These are stored in your cloud profile so they can be restored on a new phone.
- Leaderboard entries. For each finished Classic game: your player name, score, lines cleared and the time it was played. Leaderboards are visible to every player.
Information collected automatically by our partners
- Advertising. Google AdMob collects your device's advertising ID, IP address (from which an approximate location can be inferred), device and app information, how you interact with ads, and diagnostic data, in order to show ads, measure them and prevent fraud. If you buy Remove ads, the game stops showing ads.
- Purchases. In-app purchases are processed by Google Play or the Apple App Store. We receive confirmation that a purchase happened, not your payment details. The game keeps the purchase's transaction ID on your phone so it is never granted twice.
The game does not access your precise location, contacts, photos, camera or microphone. Reminder notifications are scheduled on your phone itself; no data is sent anywhere to deliver them.
2. How we use information
- To run the game and save and restore your progress.
- To show leaderboards (weekly, all-time and lines cleared) and your rank.
- To deliver the in-app purchases you buy and restore them.
- To show ads that keep the game free, and to limit fraud and abuse.
- To fix problems and keep the game secure.
3. Who we share it with
We use these service providers, which process data on our behalf or under their own policies:
| Service | What it's used for | Policy |
|---|---|---|
| Google Firebase Authentication and Cloud Firestore (Google LLC) | Accounts, cloud save, leaderboards | Firebase privacy |
| Google AdMob (Google LLC) | Showing and measuring ads | How Google uses data |
| Google Play / Apple App Store | Payments for in-app purchases | Google · Apple |
Your player name and scores are shared with other players through the leaderboards. Apart from that, we do not sell, rent or trade your personal information, and we only disclose it if the law requires us to.
4. Where it is stored and how long we keep it
Your profile and leaderboard entries are stored on Google Cloud servers, which may be outside your country. We keep them for as long as your account exists. When you delete your account they are deleted straight away and are not kept in backups. Data collected by Google AdMob, Google Play and Apple is kept according to their own policies.
5. Your choices and rights
- Delete your account in the game: Settings → Delete account. See how to delete your account and data, including how to ask by email.
- Change your player name in Settings → Name → Edit.
- Ad choices. In the EEA, the UK and Switzerland the game asks for your consent before showing personalized ads, and you can change your choice later in Settings → Ad privacy choices. Anywhere, you can reset or delete your advertising ID or limit ad personalization in your phone's settings.
- Reminders can be turned off in Settings → Reminders or in your phone's notification settings.
- Access, correction and deletion. Depending on where you live (for example under the GDPR or California law) you may have the right to access, correct, delete or get a copy of your data, or to object to how it is used. Email us and we'll reply within 30 days. You can also complain to your local data protection authority.
6. Children
Stackfall Blocks is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has given us personal information, email us and we will delete it.
7. Security
Data is sent over encrypted connections, and access to the database is restricted by security rules so each player can only change their own data. No system is perfectly secure, but we work to protect your information.
8. Changes to this policy
If we change this policy we will update this page and the effective date above. Significant changes will also be noted in the game's store listing.
