LampaPrivacy Policy
Lampa is a book reader for iPhone, iPad, Windows, macOS and Linux, made by Vladimir Zelinskyi, an individual developer. This page explains what data Lampa handles and where it goes. Lampa has no ads, no analytics and no tracking, and your data is never sold.
Without an account
Your books, reading positions, bookmarks, notes, reading lists and settings are stored only on your device. Nothing is sent to us.
With an account (optional)
You can sign in with Apple, Google, or an email and password to keep your library the same on all your devices. Accounts and synced data are stored with Supabase in the EU (Frankfurt, Germany). We store:
- your email address and account ID (with Sign in with Apple this can be an Apple private relay address);
- your library: book titles, authors, file sizes and reading positions;
- bookmarks and notes, including the text you highlighted;
- your “Read” and “Want to read” lists: titles, authors, your ratings and cover links;
- the files of books you add (up to 50 MB each), in private storage.
Only you can read this data: the database lets each account access only its own records and files. Interface settings such as theme and font are not synced.
Online features
Some features send a small amount of data to other services, which receive your IP address as part of any internet request:
- Translation on iPhone: done by Apple’s translator right on your iPhone; the text is not sent anywhere.
- Translation on a computer: the text you select and the sentence around it are sent to Google Translate.
- Dictionary: on iPhone, iPad and Mac the word you look up is shown by the system dictionary on the device. When the system has no definition, and on Windows and Linux, the selected word is sent to Wiktionary (Wikimedia Foundation).
- Catalogs (OPDS): when you browse a catalog, its pages, covers and the books you download are requested directly from that catalog’s server — Project Gutenberg or an address you added yourself. A login and password for a catalog stay only on your device and are sent only to that catalog.
- Book search, covers and ratings: what you type in the search box, and the titles and authors of books in your lists, are sent to Apple (iTunes Search), Open Library and Wikidata.
- Updates (desktop): the app checks GitHub for new versions.
Deleting your data
Delete your account in the app: Settings → Sync → Delete account. This immediately deletes your account, all synced records and the book files stored in the cloud. Books and notes on your device stay until you remove them or uninstall the app. You can also ask us to delete your account by email.
Children
Lampa is not directed at children under 13 and we do not knowingly collect their data.
