The short version. CoinCache collects nothing about you. It has no account system, no analytics, no advertising and no server. Your collection, your photographs and your notes stay on your device unless you switch on iCloud sync, which copies them to your own iCloud account and nowhere else.
On your device, and only on your device by default:
Deleting the app removes all of it from the device.
Nothing.
There is no account and no sign-up. CoinCache does not ask for your name, your email address or your phone number. It does not read your contacts, your location or your device identifiers. It contains no analytics or crash-reporting software, no advertising and no third-party tracking of any kind. No information about you or your collection is sold, shared or transmitted to the developer, and there is no server that could receive it.
Only for iCloud sync, and only if you switch it on.
Sync copies your collection file and your coin photographs into your own iCloud account, using Apple's iCloud Drive. It is your storage and your Apple Account; the developer has no access to it and no way to see what is in it. Apple's handling of iCloud data is governed by Apple's own privacy policy.
Switching sync off leaves everything already on the device untouched. With sync off, CoinCache makes no network connections at all and works with no signal.
CoinCache does not look up coin prices, fetch images, or contact any other service. The entire catalog of coins and mintage figures ships inside the app.
CoinCache asks for camera access only when you choose to photograph a coin, and iOS will show you that request the first time. Photographs taken this way are saved into the app and are not added to your photo library.
Choosing an existing picture uses Apple's system photo picker. That picker runs outside the app and hands over only the single image you select, so CoinCache never has access to the rest of your photo library.
Photographs are stored on your device and, if sync is on, in your iCloud account. They are not uploaded anywhere else.
CoinCache can produce a file describing your collection so a friend can compare theirs against it. That happens only when you tap Share, and you choose who receives it and how.
The file lists only which coins you own, and the achievements you have reached. It deliberately excludes what your coins are worth, your notes, your photographs, their condition and when you acquired them — a collection with prices attached is an inventory of valuables tied to a named person, and unlike everything else the app writes, this file is meant to leave your device and cannot be recalled afterwards.
The name attached to a snapshot is whatever you type in. It does not have to be your real one. Sharing does not go through the developer or any server; the file goes directly from you to whoever you send it to.
Exporting a backup writes a file containing your whole collection, including values and notes. Where that file goes and who can read it is entirely up to you. Treat it as you would any document listing things you own — in particular, do not attach one to a public bug report.
CoinCache is suitable for all ages and collects no personal information from anyone, including children under 13. It has no chat, no user accounts, no content submitted by other users and no links out to the web beyond this policy.
There is no data held by the developer, so there is nothing to request a copy of or ask to have erased.
If the app ever starts handling information differently, this page will be updated before that version is released, and the date at the top will change.
