keepthis.site от José Galisteo

keepthis.site is a personal bookmark manager that lives on your
computer. This extension is the toolbar button: click it and the
current tab — its URL, its title, the tags you typed, the note you
wrote — is sent to the desktop app and saved locally. From there
the desktop app captures a real screenshot, builds full-text search,
and (optionally) syncs encrypted copies to your other devices.

Why a separate desktop app?
- All your bookmarks live in a SQLite database on your machine. The
extension never sees them; this server can only see opaque
ciphertext. If you sync, your passphrase derives the key and stays
on your devices only.
- The Mac app captures a real headless-Chromium screenshot of every
page. No iframe embeds, no third-party preview API.
- Full-text search runs locally. Thousands of pins, milliseconds to
find anything.

Requires the keepthis.site desktop app.

(Linux and Windows: build from the repository.)

How to pair (one-time):
1. Run the desktop app. It starts a tiny loopback HTTP server on
127.0.0.1:43215 — nothing outside your machine ever talks to it.
2. Open the extension's Options page → Connect.
3. Verify the pairing code that appears in both windows matches.
4. Click Accept in the desktop app's confirmation dialog.

From then on, every click of the toolbar icon saves the current tab.
You can revoke the pairing any time from the desktop app's settings.

Privacy
- No analytics. No tracking. No third-party SDKs.
- The only host this extension talks to is http://127.0.0.1:43215 —
i.e. your own machine. The manifest declares nothing else.
- No content scripts; the extension does not read page content.
