Privacy Policy
Last updated: October 2026
The short version: we keep the least we can, we never sell it, and you can delete all of it from Settings whenever you like. The longer version is below.
What we keep
- A username and a device id. That is your whole account. No email, no password, nothing to forget.
- Where you were when you photographed a cat. That is what puts the cat on the map and works out whether it is one your neighbours have already met.
- The cat photos you take. They become the cards you collect, and they show on that cat’s page for other finders.
- What you have done in the game. Cats found, points, friends.
- A phone number, only if you offer one. It exists so your chonks survive a new phone.
- A push token, only if you turn notifications on.
What we do with it
Run the game. Put cats on the map, build your collection, work out the leaderboard, and tell you when a friend finds something. That is the whole list. We do not sell it and we do not hand it to advertisers.
Making the cards
Your photo goes to the service that writes the cat’s card: its name, its stats, its silly attacks. It is used for that and nothing else.
Where the cats live
Cat locations are the one thing we are strict about, because a cat is a real animal on a real street. We never show the exact spot of a cat you have not found yourself, and the person who found a cat can hide its pin entirely.
On this website
We count visits with PostHog to see which pages people read. We use Google Ads, and a similar tool from OpenAI, to see which of our ads brought people to Chonk Finder.
In Europe and the UK, Google’s ad cookies stay off. None of this ever includes your photos, your cats or where you found them.
What you can do
- Turn notifications on or off in Settings.
- Delete your account in Settings, under Delete account. It takes your personal information with it, and there is no undo.
Invite links
- When you open a friend’s invite link we note the code, and a one-way hash of your network address, so that the invite still reaches us after you install the app. We never store the address itself, only the hash, and it cannot be turned back into an address.
- It is a matching key with a thirty minute life, not a record of who visited. Rows are deleted automatically, whether they were matched or not.
- If two different invite codes are waiting behind the same network address, we credit neither. A household or a cafe shares one address, and we would rather miss an invite than credit the wrong person.
Talk to us
A real person reads this address. If anything here worries you, write to hello@chonkfinder.app.
