Your library, on your device.
This policy explains how Mirrorleaf: A Quiet Library (风月鉴, “Mirrorleaf”) handles information. Mirrorleaf does not require an account and does not include advertising or third-party analytics or tracking SDKs.
We do not operate a server that receives your books, notes, reading history, or profile. Optional web browsing, Apple purchases, and system services work as described below.
1. Information stored locally
Mirrorleaf saves your library and preferences in the app’s storage on your device. This includes imported or downloaded files, book metadata, reading positions and statistics, bookmarks, highlights, notes, imported fonts, selected images, and any profile name, signature, or avatar you choose to add.
This information is used to provide reading, customization, and progress features. It is not automatically uploaded to us. Mirrorleaf does not provide an account-based cloud library. Depending on your device settings, Apple’s device backups or transfers may include app data; those services are managed by Apple.
2. Files, photos, and system features
You choose the files and photos to import using system pickers. Mirrorleaf copies selected items into its local storage to display books, fonts, covers, wallpapers, or an avatar. The photo picker does not give Mirrorleaf unrestricted access to your photo library.
If you choose system actions such as translation, Writing Tools, or sharing selected text, the selected content may be handled by Apple or the service you choose under that service’s settings and privacy policy.
3. Web search and downloads
When you use web search, browse a page, or download a file, your device connects directly to the search engine or website. Search terms and ordinary connection information, such as your IP address and browser information, are sent to that service. Websites may use cookies or other storage in the in-app browser.
These services handle information under their own policies. Mirrorleaf does not proxy those requests through a developer-operated server or automatically send your local library to a search engine.
4. Purchases and redemption
Purchases, purchase restoration, and Apple offer-code redemption are handled through Apple’s App Store and StoreKit. Mirrorleaf uses Apple-verified transaction and entitlement information to determine whether Unlimited Bookshelf is unlocked.
We do not receive your payment card details. Apple processes payment and account information and may separately provide developers with App Store sales reports or diagnostics according to Apple’s policies and your settings.
5. Retention and deletion
Local information remains in the app until you remove it or delete the app. You can delete books, annotations, and imported fonts through the available app controls. Removing a book from the shelf may leave its original file in My Files so it can be imported again; remove that file there if you no longer want it.
Deleting the app removes its local app storage; offloading the app may preserve that data. Copies you exported, device backups, files in other apps, and Apple purchase records are managed separately and are not deleted by removing a book or uninstalling Mirrorleaf.
6. Contacting support
If you email us, we receive your email address, your message, and any attachments you choose to send. We use these to answer your request and keep the correspondence as needed to resolve it or meet legal obligations. You can contact us to request deletion of support correspondence, subject to those obligations.
Please send only the information needed for your request. Your books or notes are not automatically attached to a support email.
7. Children’s privacy
Mirrorleaf is a general-purpose reading app and is not specifically directed to children under 13. We do not knowingly collect children’s personal information through the app. If you believe a child has sent personal information to our support address, please contact us.
8. This privacy website
This page does not embed analytics, advertising, or external font services. When hosted on Vercel, Vercel may process IP addresses, request information, and security or operational logs to deliver and protect the website. This is separate from your local Mirrorleaf library.
9. Changes and contact
We may update this policy when the app or its data practices change. The date above identifies the latest revision.
For privacy questions or requests, contact Mirrorleaf’s developer at veliatytti@gmail.com.
