Get the app & make yoursCarry your carefully saved memories forward.
We are preparing an on-device importer for the export ZIP that Oshibana will provide from August 20, 2026. It is designed to let you review and import fave details, groups, activity notes, galleries, and profiles.
- Names, birthdays, fan-since dates, and signature colors
- Fan names, fan marks, groups, and profiles
- Activity notes, registered photos, and galleries
The ZIP’s final internal format will be verified when exports become available on August 20. The original ZIP is never modified, and unmatched data is not silently discarded.

Privacy Policy
Last updated: August 10, 2026
Particles and Waves ("we", "us") respects the privacy of users of notaps: Oshi ("the App") and is committed to protecting personal information.
1. Information We Collect
The App stores the following information locally on your device:
- Information about the artists you register (artists, talents, etc.)
- Notes and custom images you set
- App settings (theme, language, etc.)
- Images added to your photo album
Private notes, photo albums, and schedules stay on your device by default and are not sent to our servers. Only if you enable automatic iCloud backup in Settings does the App save a complete backup to your own private iCloud Drive area; we do not receive or have access to its contents. Only when you voluntarily post to a community feature such as Hitokoto do we send the post text, fave name, optional nickname, a device-generated identifier, and an image selected as a public avatar to Supabase, a service provider we use. Public avatar images are resized before upload and used for automated safety screening.
2. Third-Party Services
The App uses the following external APIs to display content:
- Wikidata API (for artist information)
- Rakuten Ichiba API and Yahoo! Shopping API (for related merchandise search)
- Various ticket-sales-site APIs (for event information)
- News APIs (for related news)
- Apple iCloud Drive (only if you enable automatic backup in Settings)
Requests to content APIs do not contain personal information; only search keywords such as artist names are transmitted. iCloud backups are stored in a private area managed by your own Apple Account.
3. Analytics
The App uses Firebase Analytics for service improvement and debugging, collecting screen views, button interactions, device and OS information, anonymous identifiers, and performance data. When Apple Watch features are used, summarized session type, duration, calories, a hash of the fave name, and in-app scores may be sent; raw heart-rate samples are not sent. We do not directly collect names, email addresses, or Apple IDs through analytics, and do not use this data for cross-app advertising tracking.
4. Affiliate Links
Some links in the App participate in affiliate programs. If you purchase a product through one of these links, we may receive a referral fee. This does not result in any additional cost to you.
Participating services: Rakuten Ichiba, Yahoo! Shopping, A8.net, and others.
5. Subscription Information
The App offers monthly and annual auto-renewing subscriptions through the App Store. Apple manages credit-card and other payment details, which we do not receive. We may analyze purchase, renewal, and cancellation state together with an anonymous identifier to improve the purchase flow and features, but not to directly identify you or for advertising tracking.
6. Data Storage and Deletion
Core private data such as registered faves, notes, schedules, and photo albums stays on your device and can be deleted in the App or by deleting the App. Automatic iCloud backup is off by default and can be stopped in Settings. Backups stored in iCloud can be managed or deleted from Data Protection in the App or your Apple Account’s iCloud storage settings. Turning automatic backup off by itself does not automatically delete existing backups, to avoid accidental data loss. A public Hitokoto post can be deleted from its long-press menu. A public avatar remains on the server only as needed to display the post. Send deletion or privacy requests through Settings > Feedback in the App. Anonymous Firebase Analytics data may be retained according to the service provider’s retention period.
7. Children's Privacy
The App is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13.
8. Changes to This Policy
This Privacy Policy may be updated as needed. We will announce significant changes within the App.
