Storage
Watermelon Backup stores credentials required by Nodes in iOS Keychain on the device. For OneDrive, the Keychain record stores account identity metadata, while Microsoft access and refresh tokens are managed by MSAL's token cache. For Dropbox and Google Drive, refresh tokens are stored in Keychain, saved account identifiers are used for account verification, and short-lived access tokens stay in memory.
Logs
Passwords, private keys, access keys, and tokens are not written to diagnostic logs.
