# Seedvault
[![Build](https://github.com/seedvault-app/seedvault/workflows/Build/badge.svg?branch=master)](https://github.com/seedvault-app/seedvault/actions?query=branch%3Amaster+workflow%3ABuild)

A backup application for the [Android Open Source Project](https://source.android.com/).

## Features
- Backup application data to a flash drive.
- Restore application data from a flash drive.
- User-friendly encryption using a mnemonic phrase (BIP39).
- Automatic daily backups that run in the background.

## Requirements

- Android 11

For older versions of Android, check out [the branches](https://github.com/seedvault-app/seedvault/branches).

## Getting Started
- Check out [the wiki](https://github.com/seedvault-app/seedvault/wiki) for information on building the application with 
AOSP.

## What makes this different?
This application is compiled with the operating system and does not require a rooted device for use.
It uses the same internal APIs as `adb backup` which is deprecated and thus needs a replacement.

## Permissions
* `android.permission.BACKUP` to back up application data.
* `android.permission.ACCESS_NETWORK_STATE` to check if there is internet access when network storage is used.
* `android.permission.MANAGE_USB` to access the serial number of USB mass storage devices.
* `android.permission.WRITE_SECURE_SETTINGS` to change system backup settings and enable call log backup.
* `android.permission.QUERY_ALL_PACKAGES` to get information about all installed apps for backup.
* `android.permission.INSTALL_PACKAGES` to re-install apps when restoring from backup.
* `android.permission.MANAGE_DOCUMENTS` to retrieve the available storage roots (optional) for better UX.

## Contributing
Bug reports and pull requests are welcome on GitHub at https://github.com/seedvault-app/seedvault.

This project aims to adhere to the [official Kotlin coding style](https://developer.android.com/kotlin/style-guide).

## Third-party tools

The [Seedvault backup parser](https://github.com/tlambertz/seedvault_backup_parser)
allows you to decrypt and inspect your backups.
It can also re-encrypt them.

Update README.md to reflect latest features and permissions 2019-11-30 20:32:39 +01:00			* `android.permission.BACKUP` to back up application data.
Request backoff when asked to backup to network storage while no internet available K/V backups are normally only attempted when charging and having an (un-metered) internet connection. However, if the system could not do a backup for more than a day, it ignores these requirements and still attempts a backup run. If a backup storage is used that is only accessible on the internet, but there is no internet connection, the backup attempt will fail. Therefore, we check if our storage requires the internet and if so, we treat it similar to a removable storage, by rejecting backup attempts and suppressing error notifications. 2020-10-19 20:44:36 +02:00			* `android.permission.ACCESS_NETWORK_STATE` to check if there is internet access when network storage is used.

Enable backup of call logs It turned out that call log backup is already in AOSP, but it is disabled by an undocumented flag. This commit sets this flag (for new and existing installs) to enable call log backup. 2020-09-02 19:37:02 +02:00			* `android.permission.WRITE_SECURE_SETTINGS` to change system backup settings and enable call log backup.
Add QUERY_ALL_PACKAGES permission which is now needed on Android 11 2020-09-10 14:26:55 +02:00			* `android.permission.QUERY_ALL_PACKAGES` to get information about all installed apps for backup.
