--- title: Managing data --- # Managing Your Data ## Automatic message deletion Here you can choose to delete messages from your local chat database after a set period of time. **Please note**: This option does not delete messages for other users, only for you. This option is set independently for each chat profile. ## Chat Database To open your chat database settings: - [Open the app settings](./app-settings.md#opening-the-app-settings). - Tap on "Database passphrase & export" button. ### Database passphrase By default, database passphrase is random, you have to set it manually to be able to export it. ### App data backup Here you can allow the system to back up app data, wherever it is configured. A database passphrase must be set to use this. ### Export database Here you can export the chat database to a file. ### Import database Here you can import the chat database from a file. ### Delete database Here you can delete your chat database. WARNING: Results in a loss of all your SimpleX Chat data! Unless you have just exported the chat database. ## Delete files and media You can delete all sent and received files and media stored in the app via this option, without deleting the messages.
