Privacy policy

Overview

Autumn Reader is an open-source reader for PDF and EPUB files. An account is required to access the library. Local books are associated with that account on each device; signing out hides them without deleting their local files.

You can choose which books to sync between devices. The app uses Supabase for authentication and account data, and Cloudflare R2 for synced book files.

Data stored on your device

When you use Autumn Reader, the application may store the books you add, book titles and covers, file format, favorites, dates related to adding or opening a book, reading position and progress, font-size preferences, notes, selected quotations associated with notes, and application preferences such as language, theme and reading font.

This information supports your library, reading progress, favorites, notes and reader settings. Local books and their personal metadata are accessible in the app only to the account that owns them on that device. Selected data may also be synchronized when cloud features are enabled.

Platforms and permissions

Autumn Reader is distributed across desktop and mobile platforms, and some features may differ depending on the operating system and application version.

The application needs access to files you choose in order to import and read PDF or EPUB books. Platform stores and operating systems may also process technical information needed to download, install, update or run the application under their own privacy terms. Those platform processes are separate from Autumn Reader's local library data.

Data sharing and third parties

Autumn Reader does not include advertising functionality in the current project and does not use your library to serve personalized ads. The current application code does not include a first-party analytics or telemetry system that uploads your reading activity to an Autumn Reader server.

Supabase processes account credentials and synchronized metadata. If you choose Google sign-in, Google and Supabase process the authentication information supplied by Google, such as your email address, name and profile image. Book files selected for cloud sync are stored in Cloudflare R2. If you request a translation, only the selected text fragment is sent to the configured translation service; the entire book is not sent.

If you request cloud speech, only the selected, server-verified book fragment is sent to Amazon Polly. Generated audio is stored privately in Cloudflare R2 for the configured retention period. DeepL and Polly usage ledgers store counts and technical hashes, not book text. If you purchase Autumn Pro, Lemon Squeezy processes checkout and payment data under its own privacy terms; Autumn Reader stores provider identifiers, payment status, adjustments, disputes and entitlement dates, but not full card details.

Distribution platforms such as Microsoft Store or Google Play may separately process account, device, download or diagnostic information according to their own policies.

Retention, deletion and control

Local library data remains on the device until you remove the relevant content or clear the application's data. The exact effect of uninstalling the application can depend on the operating system and its storage rules.

Signing out does not delete local books. Removing a book from cloud storage leaves its local copy on that device if one exists; it may no longer be downloadable on other devices.

The website is hosted through GitHub Pages. GitHub may process technical information associated with visits to hosted pages according to GitHub's own privacy practices. Links to Microsoft Store, Google services, GitHub or other external services take you to services governed by their respective privacy policies.
