Privacy Policy

Mosaic Critters · by PyroDadDev · Effective 27 October 2026

In short: Mosaic Critters has no accounts to make and never asks for your name, email address or contacts. Your progress, album and settings are saved on your phone and nowhere else. The free version shows ads from Google AdMob, which collects some device data. In the UK, EEA and Switzerland you are asked for consent first, and you can change your choice at any time in Settings. Uninstalling the app deletes everything.

Who we are

Mosaic Critters (“the app”) is made by PyroDadDev (“we”, “us”), an independent developer based in Wales, United Kingdom. We are the controller of the app data described below. For anything about this policy or your data, email pyrodaddev@googlegroups.com.

Information kept on your device

Your whole game is saved on your device, in the app’s own storage:

your daily solves: which boards you solved, on which dates, your times and how many peeks you used (this is your album);
your streak and best streak, your practice tallies and best times;
any board you left part-way through, so you can resume it;
how many peeks you have used today and any peeks earned from optional ads;
your settings: timer, sound and haptics;
counters that keep ads to the limits we promise;
whether you have bought “Remove Ads”.

None of this is sent to us. We have no server for the app and no analytics of our own.

Uninstalling the app deletes all of this from your phone. If your phone’s Android backup is switched on, Android may also include the app’s saved data in your Google backup, so it can come back when you reinstall or set up a new phone. That backup is kept by Google in your Google account, and you can manage or delete it in your phone’s backup settings.

Advertising (Google AdMob)

The free version shows an occasional full-screen ad after you leave a finished board (never while you are solving one), and optional ads you can choose to watch for more peeks. Ads are provided by Google AdMob through the Google Mobile Ads SDK, the only third-party service in the app that processes data. Google acts as an independent controller of the data it collects. To serve ads, limit repeats, measure performance and prevent fraud, the SDK may collect:

Data	Examples
Device identifiers	Android advertising ID; on iPhone, the ID for vendors (the app does not ask for iPhone tracking permission)
Approximate location	derived from your IP address
Ad interactions	which ads were shown, watched or tapped
Diagnostics	device type, operating system, crash and performance data

Learn how Google uses this data at How Google uses information from sites or apps that use our services, and in Google’s Privacy Policy.

Your ad choices

UK, EEA and Switzerland: on first launch you see Google’s consent message (the Google User Messaging Platform), with the choice to consent, not consent, or manage options. Personalised ads are only shown if you agree. You can change your choice at any time in Settings → Ad privacy choices.
Android: you can reset or delete your advertising ID in your device settings (Settings → Privacy → Ads, or Google → Ads on some devices).
Fewer ads: the one-off “Remove Ads” purchase switches off the between-board ads for good and makes peeks unlimited. Optional ads stay available only if you choose to watch them.

In-app purchases

“Remove Ads” is sold through Google Play (Google Play Billing) or, on iPhone, the Apple App Store, which handle payment. We never receive your payment details, only confirmation that the purchase was made, so the app can switch ads off and restore the purchase on a new device.

Sharing

If you tap Share, your device’s share sheet opens with a short message (your solve, or a line about the app) and a link to our website. Nothing is sent unless you choose where to send it, and the app does not see where it went.

Deleting your data

Everything the app keeps is on your phone. To delete it, uninstall Mosaic Critters: your album, streak, times, saved boards and settings are removed with it. If you use Android backup, you can also delete the app’s backup in your phone’s backup settings. We hold no copy, so there is nothing for us to delete on our side. Ad data is held by Google; use the ad choices above, and Google’s own controls, for that.

International transfers

Google may process the advertising data described here outside the UK, including in the United States. For ads, Google is an independent controller and describes its own safeguards in its privacy policy.

Legal bases (UK GDPR and EU GDPR)

The app itself processes no personal data of yours on our behalf: it keeps your game on your own device. In the UK, EEA and Switzerland, ads only store or read information on your device for advertising, and only use your data for personalised ads, if you consent. You can withdraw consent at any time as described above. Without consent, Google can show limited ads, which aren’t personalised and don’t use your device’s storage or advertising ID to choose ads. Showing those, keeping to our ad limits, counting ads and preventing fraud rely on our legitimate interest in keeping the app free and secure.

Children

Mosaic Critters is a general-audience puzzle game and is not directed at children under 13. We do not knowingly collect personal information from children. The app works the same way for every player: no accounts to make, nothing sent to us, and in the UK, EEA and Switzerland, personalised ads only with consent. If you believe a child has provided personal information through an ad, contact us and we will help.

Your rights

Depending on where you live, you may have the right to access, correct, delete, restrict or object to the processing of your personal data, and to withdraw consent. Because the app keeps everything on your phone and sends nothing to us, we hold no records about you to act on; ad data is handled by Google via the links above. You can also complain to your data protection authority. In the UK that is the Information Commissioner’s Office (ico.org.uk).

Changes to this policy

If this policy changes, we will update the copy on our website at pyrodaddev.github.io/mosaiccritters/privacy and the effective date above, and ship the new text in the next app update. Significant changes will also be noted in the app’s store listing.
