Overview
Muse Shelf is a personal media library. Your library, categories, statuses, profiles, notes, ratings and preferences are stored on your device. Optional accounts, cloud sync, purchases and other online features are described below. Muse doesn't sell your information, and it doesn't track you across other companies' apps and websites.
Information you add
You may add titles, custom items, categories, profiles, notes, ratings, statuses and backup files. Muse uses this information to run your library, organize it, suggest things to discover, and make backups.
Imports and backups
When you import from another app, such as Letterboxd or Goodreads, the file or text you choose is read on your device. Muse then looks up the titles it finds through its metadata service to add covers and details. The import file itself isn't uploaded.
If you export a backup, the file is created for you to store or share outside the app. If you import a backup, Muse uses the file you choose to add library data on your device.
Optional accounts and cloud library
If you create a Muse account, Muse uses your email address and account identifier to sign you in. Signing in with Google or Apple also shares the identity information you authorize, such as your name and email address, with Muse through Supabase Authentication. Muse never receives your Google or Apple password. Apple may provide a private relay address if you choose Hide My Email.
Signing in doesn't copy your device library to your account. If you choose to use the cloud library, the profiles, titles, notes, ratings, covers and other library data you copy or add there are stored using Supabase and processed by Muse's Cloudflare-hosted service. Cloud changes can keep previous versions to support version history and undo.
Connected apps and AI services
If you connect another app or AI service, it can access the Muse profiles, and the read or edit permissions, that you authorize. You can revoke that access in Muse. Information shared with a connected service is also covered by that service's privacy policy.
Feedback
If you send feedback from the app, Muse stores your message, the kind of feedback, the app version and the platform, so the developer can read it and reply. When you're signed in, it's linked to your Muse account. Otherwise it's linked to a random code saved on your device (the server keeps only a hash of it), so you can see replies.
Titles, Explore and alerts
When you search, browse Explore, view details, or open trailers, screenshots, wiki links, cast or crew, Muse requests that information from its metadata service and from third-party services such as TMDB, IGDB, AniList and Apple. Those services may receive technical information, such as your device's IP address and the search or title requested.
Release, new-episode and season-premiere alerts are scheduled on your device. To plan them, Muse asks its metadata service for the episode calendars of shows in your library.
Purchases
Muse Pro and earlier purchases are paid through Apple. Muse uses RevenueCat to check purchases and manage Pro access. RevenueCat receives purchase and receipt details and an app user ID, which is your Muse account ID when you're signed in, so Pro follows your account. Muse never sees your payment card details.
Ads and ad measurement
Without Muse Pro or the earlier Remove Ads purchase, Muse may show banner ads from Google AdMob. Muse requests non-personalized ads only and doesn't ask to track you. AdMob may still process information such as your device's IP address to deliver ads, limit how often you see them and prevent fraud, as described in Google's policies.
If you found Muse through an Apple Search Ads ad, Apple's AdServices framework provides a campaign attribution token. RevenueCat uses it to report which ad campaign led to downloads, trials and purchases. It doesn't identify you personally or follow you across other apps.
Children's privacy
Muse Shelf isn't intended to collect personal information from children. If you believe a child has shared personal information with Muse, contact support so it can be removed.
Deleting your data
You can remove library data by deleting items, using Settings › Delete all data, or uninstalling the app. Backup files you exported must be deleted from wherever you saved or shared them.
To delete your Muse account, open Settings › Muse account › Delete account. It permanently deletes your account and what's stored with it: your cloud library and covers, version history, AI connections and feedback. The library on your device stays. Deleting your account doesn't cancel an App Store subscription; cancel it in your Apple account.
Changes
This policy may change when Muse's features, services or legal requirements change. The latest version is always on this page.
