Privacy Policy
Last updated [DATE]. Calendle is made by [LEGAL ENTITY]. Questions about this policy go to [CONTACT EMAIL].
This policy describes exactly what Calendle stores, where it lives and how long it stays. It is written to match what the app actually does.
The short version
Calendle asks for no personal details. There is no sign-up form, no email address, no phone number and no advertising identifier. You never type a name. If you play offline, nothing leaves your phone at all.
Playing offline
Choosing "Play offline" creates no account and sends nothing to our server. Your puzzles, times and records stay on the phone. Nothing in this policy's "on our server" section applies to you.
If you play with an account
A guest account is an identifier our server generates. It is not derived from your phone, your hardware or anything about you, and it is not shared with anyone.
Signing in with Google gives us one thing: the opaque account identifier Google issues for you. We do not receive and do not store your email address, your name or your profile picture. We use that identifier only to recognise you as the same player on another phone.
What we store on our server
For an account, we keep:
- The account identifier, and whether it is a guest or signed in with a provider
- Your display name, and when you last changed it
- Your leaderboard scores and ranks, for the daily and random ladders
- Which dates you have solved, and how long each solve took
- Your coin balances, hints and streak freezes, and when you last claimed a gift
- A small settings record: sound, haptics, board colours and reminder preference
- Identifiers of solves already counted, so a solve sent twice is not scored twice
- Daily counters, so the limits on scored solves and rewards can be enforced
If you buy something, we keep the store's transaction identifier, what was bought, the platform, what it granted, and the receipt the store returned. We never see or store your card details: the App Store handles payment entirely.
For a signed-in device we keep only a SHA-256 hash of the access token, not the token itself, so a copy of our database cannot be used to sign in as you.
What we never collect
No email address, phone number, contacts, calendar, photos, microphone, camera, precise or coarse location, health data, or advertising identifier. Calendle contains no advertising SDK, no third-party analytics and no cross-app or cross-site tracking, so there is nothing to opt out of.
Your display name
Names are assembled from two fixed word lists — an adjective and a noun, plus a number if another player already has that pair. You cannot type free text, which is deliberate: it means no one can put anything abusive or identifying on the leaderboard, including you.
What other players can see
Your display name and your score, on the leaderboard. Nothing else. Solve times also feed an anonymous aggregate — "faster than 63% of players today" — which names nobody.
What is kept on your phone
Separately from the server, the app stores on the device: your preferences and comfort options, your streak, your best time per weekday, the solutions you have found, your achievements, how many dailies you solved without a hint, any solve that could not reach the server yet, and your access token. Deleting the app removes all of it.
Notifications
The daily reminder and the gift nudge are scheduled by your phone, locally. We operate no push server and hold no push token. Turning them off in Settings stops them.
How long we keep it
A signed-in session expires after a year unused. Account data is kept until the account is deleted, because scores and streaks are the point of having one.
Deleting your account
You can delete your account from inside the app: Settings, then Account, then Delete account. It asks twice, because it cannot be undone.
Deleting an account removes your scores, your solve history, the dates you solved and how long they took, your coin and hint balances, your streak freezes, your display name, your sessions and the record tying your Google account to this game. The records kept on your phone go too: your streak, your best times, the solutions you found and your achievements. Your preferences — sound, haptics, colours and the comfort options — are about the phone rather than about you, so they stay.
One thing is kept, with you taken out of it: if you ever bought anything, the record that the sale happened stays — what was bought, on which store, what it granted and when — with your account no longer attached to it and the store's receipt discarded. We keep it for two reasons. A sale has to leave a record for accounting, which is an obligation we cannot set aside at request. And that record is what stops the same purchase being credited twice, which without it could be done by deleting an account and starting again.
Children
Calendle is not directed at children under 13 and we do not knowingly collect anything from them. There is no behavioural advertising in the app.
Changes
