Blitz Cube 3D Puzzle privacy policy

Effective 15 October 2026 · app version 1.0 for iPhone and Android

Blitz Cube 3D Puzzle is a 3D puzzle game where you shoot arrows off a figure in the right order – on cubes, pyramids, castles, houses and giant mazes. The app is free and shows ads from Google. This page explains what data is used and by whom.

In short No account. Your game is stored on your phone only. Ads are provided by Google AdMob – you are asked for consent, and you see the same number of ads whatever you answer. If you buy No Ads (Reklamefri in Danish), no ads are shown, and the purchase is handled by Apple or Google Play.

Who is responsible

RegneMatik, Stationsvej 56, 5771 Stenstrup, Denmark, CVR 46775988, is the data controller for the app. Write to regnematik@gmail.com. For the ads, Google Ireland Limited is an independent controller of the data Google collects.

What the app stores – and where

Your game: completed levels, stars, best times, hints, your sound, vibration and language settings, and whether you bought No Ads. This is stored locally on your phone only and is never sent to us.
Backup on Android: if Google backup is turned on for your phone, Android may keep a copy of your game in your own Google account so it follows you to a new phone. We have no access to that copy.

Ads (Google AdMob)

The app shows an ad between levels (not during the first levels). The ads are provided by Google AdMob, which may process:

the advertising identifier – on iPhone (IDFA) only if you allow tracking when your iPhone asks; on Android the advertising ID, which you can reset or delete in the phone’s settings,
IP address and approximate location derived from it,
device type, operating system, language and app version,
which ads are shown and whether you tap them, plus crash and performance data from Google’s software.

The purpose is to show and measure ads and to prevent fraud. Personalised ads are only used if you have given consent. The first time you open the app in the EU/EEA or the UK, Google shows a consent message. If you decline, only non-personalised ads are shown. You can change your choice at any time in the app under Settings → Ad privacy, and tracking can be turned off in iPhone Settings → Privacy & Security → Tracking. On Android, go to Settings → Privacy → Ads (or Google → Ads) to reset or delete the advertising ID.

Read more in Google’s privacy policy and about how Google uses data from apps. If you buy No Ads, no ads are shown and the app no longer starts Google’s ad service.

Purchases

No Ads is bought through Apple (iPhone) or Google Play (Android), which handle payment under Apple’s privacy policy and Google’s privacy policy. We receive no payment information. The app only asks Apple or Google Play whether the purchase is complete.

What the app does not do

No account, no leaderboards and no analytics tools from us. The app does not ask for access to contacts, camera, microphone, photos or precise location. We do not sell data.

Deletion

Everything the app has stored is deleted when you delete the app. Your progress can also be deleted in the app under Settings → Nulstil fremskridt (Reset progress). Data held by Google and Apple is deleted under their own rules, see the links above.

Children

The app is not directed at children under 13, and ads are set to content suitable for a general audience.

Your rights

We hold no data about you that we could disclose or correct. If you have questions, write to us. You can always lodge a complaint with the Danish Data Protection Agency, Datatilsynet.

Changes

If we change how the app uses data, we update this page and the date at the top.
