Hibinoko turns a day's photo, mood and one-line diary into an AI-made creature card.
Q. How many creatures can I make per day?
A. Up to 3 AI creations per day. The count resets at midnight Japan time (JST, UTC+9). If a result failed to arrive because of a network problem, you may be able to receive it again from the same entry. If overall service usage reaches its limit, creation may be temporarily unavailable.
Q. Where are my photos and diary sent?
A. What you agreed to on first launch (a downscaled photo, moods, diary, etc.) is sent to Cloudflare's AI processing. Photo analysis starts as soon as you select a photo. See the Privacy Policy. Apple Health data is not used.
Q. How do I stop sending or delete my data?
A. In the App's Settings you can withdraw "Sending to AI", delete cloud temporary copies, and delete all on-device memories.
Q. Can I move my data to a new iPhone?
A. Memories are stored on your device and there are no accounts, so there is no transfer feature. Deleting the App removes on-device data.
Q. The picture or text doesn't match my photo.
A. Results are AI creations and may contain mistakes.
If an illustration or text is inappropriate or offensive, email us with the subject "Hibinoko report", the date of the entry and, if possible, a screenshot of the card. We review every report and improve generation rules and filters. Service may be suspended for confirmed abusive use.
For bugs or feedback, please include your iPhone model, iOS version, the App version (bottom of Settings) and what happened. Please do not send photos or diaries of yourself or others unless necessary.
