## What it is
Seedvault is an open-source backup application for the Android Open Source Project that backs up and restores app data, with encryption via a BIP39 mnemonic phrase. It must be integrated into a custom Android ROM at build time and cannot be installed as a regular app.

## Use cases
- back up android app data to a flash drive
- restore app data on a new phone without root
- encrypted android backups with a recovery phrase
- automatic daily backups on a custom rom
- replace deprecated adb backup
- back up android data to webdav or network storage

## When to choose
- you maintain or use a custom Android ROM and want built-in encrypted backups
- you need app data backup/restore without rooting the device
- you want offline backups to USB storage or a self-hosted WebDAV server

## When to avoid
- you have a stock, non-rooted device from a mainstream OEM
- you want a regular sideloadable backup app
- your Android version does not match a maintained Seedvault branch
