Marginalia app: privacy policy and support pages
Last updated: 2026-10-24. Developer: Ismael Florit (ismael@florit.es).
What Postila stores. Your books (EPUB/PDF files you import), your notes, bookmarks and reading positions are stored on your device. If you enable iCloud Sync in Settings, your notes, bookmarks and reading positions (never the book files) are stored in your private iCloud database, which only you can access. Postila has no servers and never receives your books or notes.
Sign in with Apple (optional). You can use Postila fully without signing in. If you choose to sign in, Apple provides an anonymous identifier that is kept on your device to recognise your purchase across devices. We do not receive or store your email address.
Advertising. The free version shows banner ads served by Google AdMob. In regions that require it, Postila asks for your consent before loading ads, and you can change your choice at any time in Settings → Privacy options. Without consent, ads are limited or not shown. AdMob may collect a device advertising identifier for ad serving and measurement according to Google’s privacy policy. Postila does not track you across other apps or websites.
Remove Ads purchase. Buying “Remove Ads” is a one-time in-app purchase handled by Apple. We do not see your payment details. Purchases can be restored from Settings.
Analytics and crash reports. Postila uses Firebase Analytics and Crashlytics to understand which features are used (for example “note created”, “document imported”) and to fix crashes. Events never include the text of your books or notes and are not linked to your identity. Analytics is disabled when you decline consent.
Data retention and deletion. Deleting a book or note in the app deletes it from your device and, if sync is enabled, from your iCloud database. Deleting the app removes all local data. You can delete iCloud data from iOS Settings → Apple ID → iCloud → Manage Storage.
Children. Postila is not directed at children under 13.
