Is it free?

Register up to 2 favorites for free. Premium supports up to 30 and renews automatically. Japan prices are ¥100/month or ¥980/year, with a 14-day trial for eligible accounts. Check the App Store purchase sheet for your local price and eligibility.

Does it work on Android?

It is currently available for iPhone and iPad with iOS / iPadOS 16 or later, plus Apple Watch and widgets. An Android version is not available.

Do I need an account? Are my records public?

No registration or login is required. Photos, personal notes and schedules stay on your device by default. You can optionally back them up to your private iCloud Drive. Public features such as Hitokoto posts and place comments share only what you choose to post.

What can I import from Oshibana?

The export ZIP importer supports fave details, groups, profiles, photos and activity notes. Open Add a fave and choose the import-from-another-app option to select and review the ZIP. Keep the original ZIP and source data until you have checked the import.

Why can’t I find imported activity notes?

As of October 15, 2026, public version 1.1.22 has an issue displaying imported notes. Version 1.1.25 improves their display and full-text reading and is under review; it is not publicly available yet. Keep the app and original ZIP, and contact us from Feedback in Settings.

Will it automatically collect every event and social post?

No. News, videos and streams depend on supported sources and your channel settings. You can also add events yourself. Confirm important dates and changes with the organizer or artist’s official sources.

Is this the same app as notaps Oshi?

Yes. The former name was notaps Oshi. The Japanese brand is now 推し部屋 (Oshibeya), also referred to as Oshi Room. It is developed and operated by Particles and Waves.

Features and Japan pricing checked October 15, 2026 against public version 1.1.22.

Privacy Policy

Last updated: October 12, 2026

Particles and Waves ("we", "us") respects the privacy of users of 推し部屋 / Oshi Room ("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.

1-1. Camera, front-facing AR (TrueDepth / ARKit), and facial information

The front-facing AR photo feature uses Apple's ARKit face tracking. On supported devices, live camera frames and face-position information are processed temporarily on your device to place a virtual acrylic stand at a suitable distance from the camera. Device motion and person occlusion may also be used for AR rendering on supported devices. The app does not read facial geometry or expression coefficients for facial analysis, and does not use this information for identification, authentication, emotion assessment, advertising, profiling, or machine-learning model training.

AR face-tracking data, such as face position, is used only in the device's memory during the AR session. The app does not persist this data in files, databases, or backups. When you close the capture screen, the app pauses the AR session and does not reuse the tracking data later. This tracking data is not transmitted or shared with our servers, analytics services, advertising services, or other third parties.

A captured photo is an ordinary 2D image combining the camera view and virtual stand, and may show your face. Facial meshes, expression coefficients, and raw depth maps are not attached to the image. Unless you choose to save or share it, the app does not persist or automatically upload the captured image. Saving stores it in the iOS Photos library, where you can delete it using Photos. Uninstalling this app does not delete photos saved in that library. If you enable iCloud Photos or similar Apple features, synchronization, retention, and deletion follow your Apple settings and Apple's practices. Sharing passes the ordinary image to the app or recipient you select in the system share sheet, subject to that recipient's practices.

This AR capture feature does not automatically upload captured photos to us or to analytics or advertising services. If you later import a photo into another feature, back it up, or explicitly select it as a public community icon, the corresponding sections of this policy apply. AR face-tracking data is not included. Anonymous action analytics do not contain face coordinates, facial geometry, expression coefficients, or captured images.

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, performance data, and approximate location inferred from an IP address. This is not GPS location data. We record that an Apple Watch report was received, but do not send health or exercise data such as heart rate, calories, or in-app scores to analytics services. 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.
