Rikka stores all your conversations, settings, and provider configurations on-device. Use the Backup page to protect that data: export a portable ZIP file for manual safekeeping, push incremental backups to a WebDAV or S3 server, or schedule reminders that prompt you to back up regularly. Navigate to Settings → Backup to get started. The Backup page is organized into four tabs: WebDAV, S3, Import/Export, and Reminder.

​
Manual Import / Export

The Import/Export tab lets you create a complete snapshot of your data and restore it whenever you need — no cloud account required.

​
Export your data

1

Open Settings → Backup → Import/Export

Tap the Import/Export tab.
2

Tap Export

Tap the Export item under Local Backup / Export. The system file picker opens.
3

Choose a save location

Navigate to a folder — local storage, an SD card, or a connected cloud drive — and confirm. Rikka saves a ZIP file containing your full database and associated files.

​
Import from a backup file

1

Tap Import

Tap the Import item under Local Backup / Export. The system file picker opens filtered to .zip files.
2

Select your backup ZIP

Locate and tap the backup file you previously exported.
3

Restart Rikka

After a successful restore Rikka shows a restart prompt. Tap Restart to apply the restored data.
Manual export is the recommended method for migrating to a new Android device. Copy the ZIP file to the new device via cable, Bluetooth, or a file-sharing app, then import it.

​
Import from other apps

Rikka can also import conversation history exported from other AI chat apps.
Tap Import from Chatbox, then select the .json export file produced by Chatbox. Rikka parses the conversation format and merges the history into your local database.

​
WebDAV Sync

The WebDAV tab connects Rikka to any WebDAV-compatible server for automatic cloud backup and restore.
WebDAV sync is compatible with Nextcloud, ownCloud, and any server that implements the WebDAV protocol — including many NAS devices.

​
Configure the WebDAV connection

1

Open Settings → Backup → WebDAV

Tap the WebDAV tab on the Backup page.
2

Enter the server URL

Paste your WebDAV endpoint URL into the Server Address field. For Nextcloud, this is typically https://your-server.com/remote.php/dav/files/username/.
3

Enter credentials

Fill in your Username and Password. For Nextcloud, generate a dedicated app password under Personal Settings → Security rather than using your main account password.
4

Set the remote path

Enter the folder path on the server where backups should be stored in the Path field. The default is rikkahub_backups. Rikka creates the folder automatically if it does not exist.
5

Choose what to back up

Toggle the Chat Records and Files segments to include or exclude each item type.
6

Test the connection

Tap Test Connection to verify that Rikka can reach the server with the supplied credentials. A success toast confirms everything is working.

​
Back up now

Tap the Backup Now button at the bottom of the WebDAV tab. Rikka uploads a timestamped ZIP to your configured remote path and updates the Last Backup timestamp shown at the top of the tab.

​
Restore from WebDAV

1

Tap Restore

Tap the Restore button. Rikka fetches the list of available backup files from the remote path and displays them in a bottom sheet.
2

Select a backup file

Each file shows its name, last-modified date, and size. Tap Restore Now on the file you want to restore from.
3

Restart Rikka

After a successful restore, tap Restart when prompted.
You can also delete individual backup files from the restore sheet by tapping Delete next to the file.

​
S3 Sync

The S3 tab connects Rikka to any S3-compatible object storage service.
S3 sync works with AWS S3, Cloudflare R2, MinIO, Backblaze B2, and any other service that implements the S3 API.

​
Configure the S3 connection

1

Open Settings → Backup → S3

Tap the S3 tab on the Backup page.
2

Enter the endpoint URL

Paste the S3-compatible endpoint into the Endpoint field. For AWS S3, use https://s3.amazonaws.com. For Cloudflare R2, use your account-specific R2 endpoint.
3

Enter your access key ID

Fill in the Access Key ID field. Create a dedicated IAM user or API token with the minimum required permissions (s3:GetObject, s3:PutObject, s3:DeleteObject, s3:ListBucket).
4

Enter your secret access key

Fill in the Secret Access Key field. This value is masked by default; tap the eye icon to reveal it.
5

Set the bucket and region

Enter the Bucket name (for example, my-rikka-backups). Enter the Region — use auto for Cloudflare R2 or a region code such as us-east-1 for AWS. The default region is auto.
6

Choose what to back up

Toggle the Chat Records and Files segments to include or exclude each item type.
7

Test the connection

Tap Test Connection to verify connectivity and permissions.

​
Back up now

Tap Backup Now. Rikka uploads a timestamped ZIP to the configured bucket and updates the Last Backup timestamp.

​
Restore from S3

1

Tap Restore

Tap the Restore button. Rikka lists all backup objects in the bucket in a bottom sheet.
2

Select a backup

Each entry shows its name, modification date, and size. Tap Restore Now to restore from that file.
3

Restart Rikka

Tap Restart when prompted to apply the restored data.
You can also delete individual backup objects from the restore sheet by tapping Delete next to the entry.

​
Backup Reminders

The Reminder tab helps you build a regular backup habit by having Rikka send a notification when your last backup is overdue.
1

Open Settings → Backup → Reminder

Tap the Reminder tab.
2

Enable reminders

Toggle on Enable Reminders.
3

Set the interval

Choose how often Rikka should remind you: 1, 3, 7, 14, or 30 days. The default is 7 days.
Once enabled, Rikka checks on launch whether the interval has elapsed since the last recorded backup. If it has, a notification appears prompting you to back up. The last backup time is updated automatically whenever you run a WebDAV or S3 backup. For manual exports, the timestamp is updated after each successful export.
Pair the 7-day reminder with WebDAV or S3 sync so that when the reminder fires you can back up in one tap without leaving the app.
