Privacy Policy

Last updated 17 August 2026

Color Hunch is made by Zeisoft. This policy covers all three places you can play: the website at colorhunch.com, Color Hunch for iPhone and iPad, and Color Hunch for Android. Where a rule applies to only one of them, it says so.

Questions, or a request to delete your data:hello@zeisoft.com.

The short version

• We never ask for your name, your email address or your phone number.
• There is no sign-up. The app makes an account for your device by itself.
• The only thing other players can see is the username you choose and your score.
• The website measures visits and App Store clicks, and nothing else.
• The app also uses advertising, analytics and crash reporting, described below.
• We do not sell your data.

Playing on the website

Your level progress and your sound preference are saved in your browser's local storage, on your own device. They are never sent anywhere, and clearing your browser data deletes them.

We count how many people visit, which pages they open, and how many go on to the App Store. That is Google Analytics, and it runs through our own server at sst.colorhunch.comrather than loading Google's script from Google — so your browser talks only to us. It stores a cookie holding a random number, which is how a second visit is recognised as the same browser rather than a new one. The number means nothing outside these pages and is never linked to a name, an email or an account, because there are none here. Blocking the cookie costs you nothing: the game plays exactly the same.

Playing in the app

Your account

The app creates an account for you on first launch, without asking for anything. It is keyed to a random identifier generated on your device and kept in the system keychain, so reinstalling the app does not cost you your progress. That identifier is not your device's serial number, your advertising identifier, or anything Apple or Google assigns — we generate it, and it means nothing outside Color Hunch.

Against that account we store what the game is made of: which stages you have finished, your stars and scores, your coin balance, hints, and whether you have an active subscription.

Your username, friends and leaderboards

If you choose a username, it is public. It appears on leaderboards next to your score, and it is how other players add you as a friend. Pick something you are happy for strangers to see — your own name is a choice, not a requirement, and we would rather you did not use it.

Purchases

Subscriptions and coin packs are sold by Apple and Google, not by us. We never see your card, your billing address or your store account. To know whether your subscription is active we use Adapty, which reads the purchase receipt the store issues and tells the app what you are entitled to.

Advertising

The free app can show ads, including the rewarded videos you can watch in exchange for a hint. Ads are delivered by AppLovin MAX, which mediates several ad networks including Google AdMob. Ad networks work with device-level advertising identifiers and technical data such as your approximate region, device model and language.

On iPhone and iPad, iOS asks you first: if you decline the tracking prompt, no advertising identifier is shared and the ads you see are not personalised. On Android you can reset or delete your advertising ID in system settings, with the same effect. A subscription removes ads entirely.

Analytics and crashes

We use Firebase Analytics to see which parts of the game people actually play, and Firebase Crashlytics to find out when the app breaks. Both work from an app-instance identifier generated on your device, not from anything that names you. Crash reports include the device model, the OS version and the state of the app at the moment it failed.

How you found us

We use AppsFlyer to tell whether an install came from an ad we paid for or from someone finding the app on their own — without it we would be spending on advertising blind. It receives your IP address, device and OS information, and, on iOS, the advertising identifier only if you allowed tracking in the prompt.

Notifications

If you allow notifications, OneSignal delivers them and holds the push token your device issues, along with your Color Hunch account identifier so a message can reach the right player. Turning notifications off in system settings stops them.

Photos

When you save a result card, the app writes that one image to your photo library. It is write-only: the app cannot read, browse or upload your photos, and never asks to.

What we never collect

• Your name, email address or phone number — unless you write to us, and then it is just an email.
• Your location. No app or page here asks for it.
• Your contacts, calendar, microphone or camera.
• The photos already in your library.
• Anything at all that we would sell to anyone.

Who processes data for us

Each of these does one job, and only that job:

• Zeisoft, on our own servers — accounts, progress, friends, leaderboards, and the puzzles the game downloads.
• Cloudflare — serving the website and its images.
• Google — Analytics and Crashlytics in the app; Analytics on the website; AdMob as one of the ad networks.
• AppLovin — the ads in the app.
• AppsFlyer — where installs come from.
• Adapty — whether a purchase is active.
• OneSignal — delivering notifications.
• Apple and Google — the stores that sell the app and handle every payment.

These companies operate internationally, so data may be processed outside your country, including in the United States. Where the GDPR applies, those transfers rest on the European Commission's standard contractual clauses or an adequacy decision.

How long we keep it

Game data stays while the account exists, because that account is your progress. Crash reports and analytics are kept on the providers' own schedules, which are months rather than years, and are aggregated well before that. Ask us to delete your account and everything attached to it goes, within 30 days.

Your choices

• Decline the tracking prompt on iOS, or reset your advertising ID on Android.
• Turn notifications off in system settings.
• Change or clear your username at any time in the app.
• Clear your browser data to erase everything the website kept.
• Subscribe to remove ads.

If you are in the European Economic Area, the United Kingdom or Türkiye you may ask for a copy of your data, ask us to correct it, or ask us to delete it. Emailhello@zeisoft.com and we will answer within 30 days. You also have the right to complain to your local data protection authority.

Deleting your app account

The website has no account, so there is nothing there to delete — clearing your browser data erases everything it kept. This is about the app, which does make one for your device.

Email hello@zeisoft.com with your username and we will delete the account, its progress, its coins and its leaderboard entries. It cannot be undone, and purchases do not come back.

The username is how we find you, because we hold nothing else that names you. If you never chose one, there is no way for us to tell your account from anyone else's — deleting the app removes the identifier from your device, and what remains on our side is a row of scores tied to a random number that nobody can trace back to you.

Children

Color Hunch is not directed at children under 13, and we do not knowingly collect anything from them. The app shows advertising, sells items, and lets players see each other's usernames, which is why it is rated for older players in both stores. If you believe a child has an account, write to us and we will delete it.

The website versus the app

Playing on the web creates nothing in the app: there is no account, no leaderboard entry and nothing to sync. The two do not know about each other.

Changes

When what we collect changes, this page changes with it and the date at the top moves. If a change is significant, the app will say so before it takes effect.
