Colorbreak

No account, no login, no analytics, no crash reporting. Everything you do in the game stays on your phone — until you challenge a friend: then the name you picked, the codes you two make and your guesses on them go to our own server, so the other phone can see them. The only other company involved is Google, and only when you choose to watch an ad for extra hint credits.

One settings file, on your own phone. It holds:

• which level you have reached, and the stars on each
• your hint credit balance, the date of the last free grant, and how many ads you have watched today
• your streak — the run of days you cleared a level on
• the level you were in the middle of, so a phone call does not cost you an attempt
• six switches: dark theme, letters on pieces, sound, haptics, reduce motion, high contrast

That file never leaves the device. It is not backed up online and it does not sync, so a new phone starts at level one — and uninstalling the game deletes it for good.

A challenge or a duel only works if both phones can see it, so this part of the game uses our own server. It runs Appwrite, open-source software, on a server we run ourselves; no other company hosts it or sees what is on it. Nothing is sent until you open a challenge yourself. Then it keeps:

• an anonymous account the game makes for your phone — no email, no password, no phone number — so a challenge knows which side is yours
• the name you type in, which is what your friend sees
• each challenge or duel: the codes you two make, the guesses you play on them, how many tries and how long they took, and who won

Only the two phones in a challenge can read it. The code your friend made for you is handed to your phone when you start cracking it, not before. None of it is used for anything else, shared with anyone or used for ads. If you want it removed, write to the address below with the name you used.

The game offers an ad in exactly one place, and never shows one on its own: the last row of the hint sheet, which you reach by opening the hints yourself. It says how long the video is and how many are left today before you commit to anything, and watching one adds two hint credits. There are no banner ads, no ads between levels, no ad on launch and no ad after a loss.

Those ads come from Google AdMob. To show them and count them, Google collects your device’s advertising ID and what you do with the ad, under Google’s own privacy policy: policies.google.com/privacy. We never see or store any of it — it goes straight to Google. You can reset your advertising ID, or turn off personalised ads, in your phone’s Google settings whenever you like.

Asking first. For players in the EU, EEA and UK, the game asks your permission before it loads any ad at all, and asks whether personalised ads are alright. You can change your answer later under Settings → Privacy settings, which only appears where your region requires it.

One: internet access, to load the ads described above and to play a friend. The game asks for nothing else — no camera, location, contacts, files, microphone or notifications.

Colorbreak is not directed at children under 13, and ad content is requested at a teen rating or lower. Nothing above changes with age.

If what the game collects, or which other companies are involved, ever changes, this page changes with it — before that build is published, not after. The date at the top is the date of the last change.
