Your codex lives here
Your codex lives on this device. Mementia has no account system and no servers of its own. If you turn on Mementia+ backup, an encrypted copy of your codex is stored in your own iCloud or Google Drive account, and Mementia does not receive it and cannot read it.
Data collection
Mementia does not create a Mementia account, store your codex on its own servers, track usage, run analytics, collect device identifiers, or access your contacts. The exceptions are the optional Mementia+ subscription and the optional Mementia+ backup, both described below.
Local storage
By default, every journal entry, Person, Place, Day, Moment, Thing, photo, note, and vibe reading is stored only on your device. It leaves the device only if you turn on Mementia+ backup, described below.
Photos
When you add a photo, Mementia copies it to private app storage on your device. By default it is not uploaded anywhere. If you enable Mementia+ backup, your photos are included in the encrypted backup stored in your own cloud account.
Subscriptions
Mementia+ is an optional paid subscription. Billing runs through your app store, Google Play or the App Store, and is tied to your existing store account, not to a Mementia account. To confirm whether your subscription is active, Mementia uses RevenueCat. RevenueCat receives an anonymous app user id and the subscription status read from your store receipt. It does not receive your journal entries, codex, photos, notes, or any other content. RevenueCat's privacy policy is at https://www.revenuecat.com/privacy.
Backup & sync (Mementia+)
Mementia+ includes an optional backup. When you turn it on and connect your iCloud or Google account, Mementia encrypts your codex and photos on your device and uploads the encrypted bundle to a private, app-only folder in your own cloud. The encryption key is created on your device and kept in your own account, so a new device can restore after you sign in. Mementia runs no servers and does not receive, see, or store your data or your key. You can disconnect at any time; the backup stays in your own cloud until you delete it.
Deletion
You can delete individual entries inside the app, or erase the entire codex from Settings. Deleted data is removed from this device.
Permissions
Camera access lets you take photos. Photo library access lets you choose existing photos. Microphone access lets you dictate journal entries: your speech is turned into text by your device's built-in speech recognition, Mementia requests on-device processing, and the audio is not stored or sent to Mementia. Those permissions are used only for those actions.
Your rights and contact
You can export your codex at any time and erase all of it from Settings. Deletion is immediate and on-device. For any question about this policy, your data, or to make a privacy request, email admin@cyberflux.in.
