Privacy Policy

Last updated: August 28, 2026

Numbra is a number puzzle game published by Pixerion. We do not ask you to create an account, and we do not collect your name, email address, or any other information that identifies you personally.

Your game progress stays on your device. The only data that leaves your device is what our advertising partner needs to show ads.

Data stored on your device

Numbra saves the following locally so the game remembers where you left off. It is never uploaded to us:

Uninstalling the app deletes all of it permanently.

Advertising

Numbra is free and supported by ads served through Google AdMob. To show ads and measure their performance, Google may collect and process:

Data Purpose
Advertising ID Selecting ads and limiting how often the same ad is shown
Device and app information Device model, operating system version, app version, language
Approximate location Derived from IP address, at country or region level only
Ad interactions Impressions, clicks, rewarded ad completions

This data is handled by Google under its own privacy policy: How Google uses information from sites or apps that use our services. Pixerion does not receive this data in an identifiable form — we only see aggregate revenue and performance reports.

Ads appear on the main menu, between levels, and when you choose to watch a rewarded ad for hint tokens or a level skip. Rewarded ads are always optional. Ads are never shown while you are solving a puzzle.

Your advertising choices

If you are in the European Economic Area, the United Kingdom, or Switzerland, Numbra shows a consent form on first launch where you decide whether personalised ads are allowed. You can change that decision at any time from Settings → Privacy options inside the game.

Wherever you are, you can reset or delete your advertising ID from your device settings: Settings → Google → Ads on most Android devices. Declining personalised ads does not restrict any part of the game — the ads you see simply become less relevant.

Permissions

Numbra requests only the INTERNET and ACCESS_NETWORK_STATE permissions, and only so that ads can load. The game itself works fully offline. Numbra does not access your camera, microphone, contacts, photos, files, or precise location.

Children

Numbra is a general-audience puzzle game. It is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the app, contact us and we will address it promptly.

Data security and retention

Because game data never leaves your device, there is no server-side copy to breach or retain. Advertising data is retained by Google according to its own retention policies.

How to delete your data

Numbra, published by Pixerion, stores all of your data locally on your device. There is no Pixerion account and no Pixerion server holding a copy, so you can delete everything yourself at any time.

Delete your game data from inside the app

  1. Open Numbra
  2. Tap Settings on the main menu
  3. Tap Reset data at the bottom of the screen
  4. Confirm in the dialog that appears

This permanently deletes your completed levels, stars, hint tokens, daily puzzle results, streak, achievements and settings. It cannot be undone, and nothing is retained afterwards.

Delete everything

Uninstalling Numbra removes the app and every file it created, including all of the data listed above. Nothing survives the uninstall.

Advertising data

Data collected by Google AdMob for advertising is held by Google, not by Pixerion, so we cannot delete it on your behalf. You can reset or delete your advertising ID from your device settings — on most Android devices, Settings → Google → Ads. Google's own retention policies then apply.

Ask us instead

If you would prefer that we handle a deletion request, email pixerion.dev@gmail.com with the subject line Data deletion request. Because we hold no personal data about you, we will reply confirming that nothing of yours exists on our side and walk you through the steps above. We answer within 30 days.

Third-party services

Changes to this policy

If this policy changes, the updated version will be published at this address with a new "Last updated" date. Significant changes will also be noted in the app's release notes on Google Play.
