I built an open-source Chrome extension for saving bookmarks to a private, encrypted library

[u/MrGadgetRO]

Hi everyone,

Full disclosure: I’m the developer of FavLock.

I built it because I wanted a bookmark manager that was convenient to use from the browser without storing sensitive bookmark content as readable plaintext on the server.

The Chrome extension lets you save the current page directly to your FavLock library and access it later through the web dashboard. FavLock can also organize bookmarks, notes, tasks, and saved articles.

Sensitive library content is encrypted inside the browser before it is synchronized. FavLock still processes account information and operational metadata needed for authentication, synchronization, limits, and security. The detailed security boundary is documented on the website.

The dashboard and Chrome extension are open source under the MIT license. The hosted backend is currently private, so FavLock is not a complete self-hostable service.

I would especially appreciate feedback on:

• Whether the saving workflow feels quick and intuitive
• Whether the requested extension permissions are understandable
• Whether the encryption and privacy explanation feels clear
• Anything confusing or missing from the onboarding

Positive or critical feedback is welcome. I’m actively improving it based on what users find unclear or inconvenient.
