Privacy policy
Last updated: November 14, 2026
The short version. DiscCrypt keeps your disc collection on your own devices. There is no DiscCrypt server and no DiscCrypt account. The developer never receives your collection, your photos or your sign-in details. The app has no advertising and no analytics.
What DiscCrypt keeps, and where
Everything you enter — the discs and films you own, formats and editions, what you paid and where, who you lent a disc to, your ratings and watched dates, and any case or shelf photos you add — is stored in files on the device you entered it on.
If you turn on syncing between your devices, a copy of those same files is also kept in the storage service you choose (OneDrive, Dropbox, Google Drive or iCloud Drive), in a folder belonging to the app in your own account. DiscCrypt does not add a password of its own to those files: they are protected by your account with that service, and by the encryption that service applies, in the same way as anything else you keep there. A list of films is not a secret worth a passphrase you could lose; if that is not true for you, do not turn on syncing.
What leaves your device
- Your collection's files, to the storage service you chose, only if you turn on syncing.
- A barcode number, to the free UPCitemdb lookup, the first time you scan a barcode DiscCrypt has not seen before, so it can suggest what the disc is. The number is sent on its own: nothing about you or your collection goes with it. The answer is kept on your device, so the same barcode is never looked up twice.
- A request for a case photo, to the shop or image address given in that lookup's answer, when DiscCrypt fetches the cover picture for a disc you add.
- Links you open go to your web browser under that website's own policy.
Nothing is sent to the developer. Barcodes and covers you have already scanned are answered from your device, with no connection at all.
Google user data
If you choose Google Drive, you sign in on Google's own page; DiscCrypt never sees your Google password. This is what it does with your Google account:
- What it can access. DiscCrypt requests two permissions: the files DiscCrypt itself creates (
drive.file) and a hidden app-data folder of its own (drive.appdata). It cannot see, list or change any other file in your Google Drive. It also reads your Google account's name and email address, to show you which account is signed in. - How it uses it. Only to store and retrieve your own collection files, so that your devices stay in step. Your name and email address are shown on your device's settings screen and used for nothing else.
- Where it is stored. The collection files are stored in your own Google Drive. The sign-in token Google issues is stored in your device's secure storage (the Keychain on Apple devices, Windows data protection on a PC). Your account name is stored on your device. None of it is stored anywhere by the developer.
- Who it is shared with. Nobody. DiscCrypt does not transfer, sell or disclose Google user data to anyone, does not use it for advertising, and does not use it to train AI or machine learning models. No person other than you reads it.
DiscCrypt's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Microsoft, Dropbox and Apple
The same applies to the other services. With OneDrive and Dropbox you sign in on the service's own page, and DiscCrypt reaches only a folder of its own there. iCloud Drive uses the iCloud account your device is already signed in to, and needs no sign-in of DiscCrypt's. In every case the folder is in your own account, and the developer has no access to it.
Camera and photos
The camera is used to scan a barcode or read a cover or shelf. Those pictures are read on your device, by the operating system's own text and barcode reading; they are not uploaded anywhere. A case photo you take or choose is stored with your collection, and synced only as part of it.
Removing your data
- On a device: delete the app, and its copy of your collection goes with it.
- In a storage service: choose "Stop syncing here" in the app on each device, then delete the app's folder in that service. In Google Drive, open Settings, then Manage apps, find DiscCrypt and choose "Delete hidden app data".
- DiscCrypt's access to your Google account: remove it at any time at myaccount.google.com/connections. The other services have an equivalent page.
Test versions
If you install a test version through Apple's TestFlight, Apple may collect crash reports and usage information under its own terms. DiscCrypt itself adds no analytics or crash reporting.
Children
DiscCrypt is not directed at children and collects no personal information from anyone.
Changes and contact
If this policy changes, the new version will be posted here with a new date. Questions: [email protected].
