Privacy Policy for BlastGrid

Last updated: 3 September 2026

BlastGrid is a block puzzle game for Android, published by BYZ DEV. This policy explains what data is involved when you play, and who handles it.

Information we collect

We do not collect, store, or transmit any personal information. BlastGrid has no accounts, no sign-in, and no servers of our own. We never see your name, email address, contacts, photos, location, or files.

Data stored on your device

The game saves a small amount of progress locally on your phone so it can remember where you were. This never leaves your device and is not sent to us or anyone else:

Your best score
Which levels you have completed, and the stars earned
How many times the game has been opened, and how many rounds you have finished (used only to decide when to show the notification permission prompt)
Your sound, music, vibration, and reminder settings

Uninstalling BlastGrid deletes all of it.

Advertising

BlastGrid shows ads through Google AdMob, which is how the game is funded. AdMob is operated by Google and collects data to select and measure ads. This typically includes:

Your device's advertising identifier (Advertising ID)
Device information such as model, operating system version, and language
IP address, which gives an approximate location
Interactions with ads shown in the app

This collection is performed by Google, not by us — we receive only anonymous, aggregated earnings reports and cannot identify any individual player. Google's handling of this data is governed by their own policy:

You can reset or delete your Advertising ID at any time in Settings → Google → Ads on your device, and opt out of ad personalisation there.

Notifications

BlastGrid can send you an occasional reminder to come back and play. These are generated entirely on your own device — no data is sent anywhere to produce them, and we do not know whether you received or opened one. You can turn them off inside the game under Settings → Reminders, or in your phone's notification settings.

Children

BlastGrid is not directed at children under 13. We do not knowingly collect any information from children. If you believe a child has provided information through the app, please contact us and we will address it.

Permissions the app requests

Internet and network state — required to load ads
Notifications — optional, only for the reminders described above

BlastGrid does not request access to your camera, microphone, contacts, location, storage, or any other sensitive permission.

Your rights

Because we hold no personal data about you, there is nothing for us to export or delete on request. Data held by Google in connection with advertising is subject to Google's own privacy controls, linked above.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date at the top.
