2. Data Storage Location and Retention Period

On-Device Storage (Basic Principle)

• Photos, voice recordings, transcription/summary data, and location information are stored exclusively on the user’s device.
• The data is retained until the app is deleted or the user selects “Delete All Data” from the settings.

Temporary Storage on External Services

• During Notion Integration: Image data, music information, and location information (address) are temporarily stored on our servers for uploading to Notion, after which they are uploaded to Notion.
• Firebase Storage: Photo data is temporarily uploaded to Firebase Storage during Notion integration and may be published as a public URL.

Storage of Authentication Information

• Notion access tokens and Spotify access tokens are stored only in the device’s Keychain and are not transmitted or stored on our servers.
