This is an English translation of the original Japanese policy. If there is any inconsistency between the two, the Japanese version prevails.

You can delete your account and your cloud data at any time from "Delete account" on the Profile screen in the App. Your data can be restored for 30 days after you request deletion; after 30 days, all of your data is permanently deleted. If you have any questions, please contact us using the address below.
The App asks for access to your camera and photo library so you can take and save training photos. If you do not allow access, you can still use every feature other than photos as usual.
The App displays ads using Google AdMob. AdMob may use your device's advertising identifier to serve personalized ads. No ads are shown while you are on the Pro plan.
For users in the European Economic Area (EEA), the United Kingdom and Switzerland, we ask for your consent in the App before processing personal data for advertising. If you do not consent, no ads are shown and no data is processed for personalized ads. All training log features remain available as usual.
You can change your choice at any time from "Ad privacy settings" on the Profile screen in the App.
On iOS, we ask for App Tracking Transparency (ATT) permission to use your advertising identifier (IDFA). This is separate from the consent described above. If you do not allow tracking, you will see non-personalized ads. Either way, all training log features remain available.
You can turn off ad personalization by Google at any time:
The App is not directed to children under 13. We do not knowingly collect personal information from children under 13.
We may update this policy from time to time. If there are important changes, we will let you know in the App.
