Threeline Privacy Policy

English version of the policy above. If the two differ, the Japanese text is authoritative.

Your data

Threeline ("the app") stores the three things you write and which days were completed only on your device, in the app's own container. The app does not send them to the developer's servers and does not share them with third parties. There is no account and no advertising.

Anonymous usage

To improve the app, the following anonymous records are sent to the developer's server.

• The kind of action taken, such as opening the app
• Which screen showed the Pro offer, and which feature triggered it
• That a widget was displayed, and its size
• the number of items written and completed (never the content)
• App version, OS version and language setting
• A random identifier generated on the device (deleted when you delete the app)
• The country of the connection (IP addresses are not stored)

The following are never sent:

• Your content — the text you write
• Contact details such as name, email address, phone number or postal address
• Advertising identifier (IDFA) or device identifier (IDFV)
• Location
• IP address

These records are not used to serve or measure advertising, are not sold or given to data brokers, and are not linked with any third party's tracking data. No third-party analytics SDK is included.

You can stop sending at any time from Settings (gear) > Privacy > "Share anonymous usage". Stopping also deletes any records not yet sent from the device.
