Privacy Policy

Last updated: November 12, 2026

FLUX BLOCK ("we", "our", or "the App") is a block puzzle game with endless, timed, daily and story modes. This Privacy Policy explains what information the App handles when you play it on Android. The App works without you creating an account or giving us your real name, email address or phone number.

Developer Information

Developer: Vertex Studio

What the App Stores

When you first open the App we create a random, anonymous player account with Firebase Authentication. It is a random ID, not linked to your identity. Under that ID the App keeps:

• Player name: the display name you type when you first open the App. You can change it at any time in Settings.
• Game progress: your best scores, number of games, lines cleared, play time, best combo, Daily streak, and the stars you have won on story levels.
• Days played: the first and the most recent day you opened the App, so we can count how many people play.
• Preferences: sound, music, vibration and display settings. These stay on your device only.

Progress is stored on your device first, so the App works offline. A copy of your name and progress is kept in our database (Google Cloud Firestore) so it can be restored. We do not collect your real name, contacts, precise location, photos or files, and we never sell personal data.

Restore after reinstalling. The App reads your phone's own identifier for this app (the Android ID) and turns it into a one-way scrambled code. We store your display name and progress under that code, so they come back if you reinstall the App on the same phone, even without signing in. We never store the Android ID itself, and we do not use this code for advertising.

Google Sign-in (optional)

In Settings you can tap Sign in with Google to link a Google account to your player ID, so your progress can be restored on another phone. This uses Firebase Authentication's Google sign-in. We then store the Google account identifier and the email address Google provides, only to find your progress again. We never post anything to your Google account or read your Google data. The App works fully without signing in.

Rankings

The Rankings boards show your display name and your best score to other players, together with your position. Nothing else about you is shown. Deleting your data (below) removes you from the boards.

Information Collected by Third-Party Services

The App uses these services. They may collect limited technical information, and they act under their own privacy policies:

• Google AdMob (players who have not bought Remove ads): shows advertisements, including optional videos you can choose to watch to keep playing. AdMob may collect device identifiers (including the advertising ID), approximate location derived from IP address, ad interactions and diagnostics. Where the law requires it (for example in the EEA and the UK), a consent form is shown before any ad is requested, and you can change your choice later in Settings under Ad privacy choices.
• Firebase Authentication and Cloud Firestore: provide the anonymous player ID (and the optional Google link) and store the name and progress described above.
• Google Play: handles the Remove ads purchase. We never see your payment details; the App only learns from Google Play that the purchase was made, and remembers that on your device.

More about how Google handles this information: How Google uses information from sites or apps that use its services and Firebase privacy information.

The App does not use analytics or crash-reporting services.

Device Permissions

• Internet: to save and restore progress, load the rankings, receive new levels and show ads. The game itself plays offline.
• Advertising ID: used by Google AdMob as described above.
• Vibration: to make the phone buzz with the game. It can be switched off in Settings.
• No camera, microphone, contacts, location, photos or files. The App does not ask for them.

Purchases

Remove ads is a single, one-time purchase sold by Google Play at the price shown in the App. It is not a subscription. Google Play handles payment; the App receives only a confirmation, so it can stop showing ads. If you reinstall the App or change phone, the purchase is restored from your Google Play account (Settings > Restore purchase).

Data Sharing

We do not sell your information. The only data that leaves your device is your display name and progress (to our database), your display name and best score (to the Rankings boards), and the technical information described above, sent to Google AdMob, Firebase and Google Play under their own policies.

Security

Network traffic to our database and to Google services is encrypted in transit. Our database rules allow each player to write only their own name, scores and progress. No method of storage or transmission is completely secure, but we take reasonable steps to protect your information.

Delete Your Data

You can delete everything FLUX BLOCK by Vertex Studio holds about you, from inside the App:

1. Open the App and go to Settings.
2. Tap Delete my data and confirm. You need an internet connection.

This removes your player account, the link to your Google account if you made one, your display name, your saved progress (including the copy kept for restoring on this phone), and your rows on the Rankings boards, and it clears the App on your phone. It cannot be undone.

If you cannot open the App, email contact@vertexstudiodot.com with the subject "Delete my data" from the Google account you signed in with, or include your display name and the phone you played on. We delete the data within 30 days and confirm by email.

What is deleted and what is kept

• Deleted: your player account and any linked Google identifier and email, display name, progress, restore copy, and Rankings rows. Rows on weekly boards older than three months, which hold only a display name and a score, are removed when you ask by email.
• Kept, by Google Play: your purchase history stays with Google Play under its policies; we never hold it.
• Kept, by Google: advertising data is handled by AdMob under Google's policies; you can reset or delete your advertising ID in your device settings.

Your Choices

• Change your ad consent choice in Settings > Ad privacy choices (shown where the law provides that choice), or reset your advertising ID in your device settings.
• Change your display name at any time in Settings.
• Buy Remove ads to stop all advertisements.
• Sign out of Google in Settings; your progress stays on your phone.
• Delete your data as described above.

Audience

FLUX BLOCK is intended for a general audience and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.
