MarkJump — Privacy Policy

Last updated: 15 August 2026

MarkJump is a Chrome extension for fuzzy bookmark search. It is built to keep your data on your own device, and this page describes exactly what that means.

What I collect

Nothing. I receive no data from the extension. There are no analytics, no telemetry, no accounts, and no tracking of any kind.

What the extension accesses

• Bookmarks — read locally to power search. They are never transmitted to me or to any third party.
• Local storage — your settings, any notes you write on a bookmark, and (only if you enable the AI option) an on-device cache of bookmark embeddings are kept in chrome.storage.local. Notes are stored beside the bookmark, keyed by its id; the bookmark itself is never modified, and a note is deleted when its bookmark is. None of it leaves your device.

Network access

The core search makes no network requests at all.

The optional AI feature is off by default. If you turn it on, the extension connects only to the endpoint you configure, and that endpoint is restricted to localhost / 127.0.0.1 — your own local Ollama server. Bookmark text (title, folder, host) is sent there solely to compute embeddings for semantic search. Nothing goes to a cloud service or a third party.

Profiles

A Chrome extension can only reach the bookmarks of the Chrome profile it is installed in. Install it only in the profile whose bookmarks you actually want to search.

Permissions, and why each one exists

Permission	Why
bookmarks	Reading them is the entire feature
storage / unlimitedStorage	Settings, and the local AI cache if enabled
alarms	Debounces the background index refresh
Optional host permission for localhost	Only requested if you enable the AI option
