ST Studios

Privacy policy

Last updated 12 October 2026.

Our apps on the App Store and Google Play are designed to work without knowing who you are: there is no registration, no login and no profile. We never learn your name, email address, contacts or precise location, and we have no way to connect what an app sends us back to you as a person.

What stays on your device

Your saved scores, progress, settings, photos and anything you create stay locally on your device and are never sent to us.

What leaves your device

So that we can tell whether an app is working and whether people keep playing it, our apps send a small amount of diagnostic and usage information to our own servers. It is not linked to your identity and is keyed to a random identifier the app generates for itself on first launch — not your device's advertising ID, not a hardware identifier, and nothing that follows you to any other app. Reinstalling the app produces a brand new one.

• Is the app still being played? Once a day: which app, its version and build, your OS version, and whether you're on iOS or Android.
• Did it crash? The error message, the technical stack trace, and which build it happened on.
• Did the app's screens work? Events such as opening the app, reaching the unlock screen, starting a free trial, or completing or restoring a purchase. We record that a purchase happened, never any payment details — those go to Apple and Google, and we never see them.
• Which country is the app used in? Our server derives your country from the IP address of the request and stores it with retention pings, usage events and crash reports. We do not keep the IP address in these records or request GPS access. This is country-level location, not your precise location.
• If you allow notifications, the notification token your phone issues, so we can tell you about a new release. Notifications are always opt-in, and turning them off in your device settings stops this.

That is the complete list. We do not sell it, we do not share it with anyone, and there are no third-party analytics or advertising SDKs in our apps — the information goes to servers we run ourselves and nowhere else.

In the App Store privacy label, these data types are called Device ID, Product Interaction, Crash Data and Coarse Location, plus Purchase History for apps with in-app purchases. They are used for analytics, and the install identifier also supports app functionality. They are not linked to your identity and are not used to track you across apps or websites. Google Play calls the country data Approximate location.

Playing in your browser

Some of our games can be played in your browser at st-studios.com. They send the same kind of anonymous events as the apps — the game loaded, your first tap, each round started and finished, how long you played — plus which site sent you (for example st-studios.com) and a random identifier kept in your browser's local storage. Clearing your browser data removes it. The website also records which pages are viewed and when someone taps an App Store or Google Play button. None of it includes your name, email or anything else that identifies you, and none of it goes to a third party. The links to our store listings carry a short campaign label so the stores can tell us how many installs came from our site.

Adverts

Our apps show no adverts. No ad networks, no ad identifiers, no tracking for advertising purposes, and nothing that asks for permission to track you across other companies' apps.

App store platforms

Separately from the above, Apple and Google provide us with aggregated, anonymised statistics about downloads, crashes and usage through App Store Connect and Google Play Console. These are governed by Apple's and Google's own privacy policies and never identify you to us.

Cookies

We don't use any cookies in our apps.

Children

Several of our apps are made for all ages, young children included. We collect no personal information from anyone, so we collect none from children either. The anonymous diagnostics described above exist only to keep the apps working and to tell us whether people are still playing — they are never used to build a profile of anyone, never used for advertising, and never sold or shared. Where an app is aimed at younger children we would rather not hold a notification token at all, so notifications may be switched off entirely in that app.

How long we keep it

We keep the diagnostic and usage records described above for no longer than 24 months, after which they are deleted.

Deleting your data

Because there is no account, the simplest way to break the link entirely is to delete the app — the random identifier goes with it and is never reissued. If you would like us to delete the records already held for your install, ask us through our support page and we'll do it.

Changes

If an app ever starts collecting data beyond what's described here (for example, online leaderboards), we'll update this policy and the app's store listing before the change ships.
