Privacy & your data
BookMark Pro is built around one hard rule: no feature ever sends your data off your device.
Where your data lives
Section titled “Where your data lives”All bookmarks, folders, icons, and settings are stored in IndexedDB, your browser’s built-in local database. There is:
- No backend — the app has no server to talk to.
- No account — nothing to sign up for, nothing to log in to.
- No telemetry or analytics — the app doesn’t track what you do.
- No external assets at runtime — the app doesn’t load scripts, fonts, or other resources from third-party servers while you use it.
What about favicons?
Section titled “What about favicons?”When you add a bookmark, BookMark Pro looks up the site’s icon so your grid looks right. That request goes directly from your browser to the site you bookmarked — the same kind of request your browser makes when you visit the site. No intermediary service is involved, and once fetched, the icon is stored locally alongside your bookmarks so it works offline. See Icons & favicons.
Infrastructure
Section titled “Infrastructure”Your bookmarks, folders, and settings never leave your device — but the app itself (its HTML, JS, and CSS) has to be served from somewhere so your browser can load it in the first place.
- No big tech deployment — the app isn’t hosted on infrastructure run by large US cloud/advertising platforms.
- European hosting — it’s served from European hosting providers with a strong commitment to GDPR compliance.
- Static files only — these servers only ever serve the app’s static files. They don’t receive, process, or store your data; your bookmarks stay local as described above.
What this means for you
Section titled “What this means for you”Your data is yours. You can export everything to a single file at any time — there is no lock-in.
Your data is local. The flip side of local-only storage: your bookmarks live in this browser on this device. They don’t sync between devices, and clearing your browser’s site data will delete them.
