MarkPage Privacy Policy

Last updated: 2026-04-15

MarkPage (“the Extension”) is committed to protecting your privacy. This policy explains what data the Extension accesses, how it is used, and what we do — and do not — do with it.

TL;DR

All of your data stays on your own device.
We do not operate any server. We do not collect, store, or transmit any data to ourselves.
The Extension only talks to the AI endpoint you configure in Settings, using your own API key, and only when you opt in to AI features.

What data the Extension accesses

Data	How it is used	Where it is stored
Your Chrome bookmarks (titles, URLs, folder structure)	Render the new tab page; allow you to search, edit, tag, move, pin, and delete bookmarks	Chrome’s native bookmark store on your device
Tag definitions and bookmark-to-tag mapping	Power the tag system	`chrome.storage.local` on your device
AI configuration (endpoint URL, API key, model name)	Call the AI service you configure	`chrome.storage.local` on your device
UI preferences (theme, accent color, language, frequent list, recent searches)	Personalize the interface	`chrome.storage.local` on your device
Active tab title and URL (popup only, when opened)	Pre-fill the bookmark you are about to save and let AI suggest a category	Memory only — never persisted by the Extension

What we send to third parties

The Extension itself does not send your data to any server we operate.

When the AI feature is enabled, the Extension sends the title and URL of the bookmark being processed to the AI endpoint you configured in Settings (e.g., your own OpenAI-compatible API). This call is made directly from your browser to that endpoint; it does not pass through any infrastructure controlled by us.

The Extension also loads the Space Grotesk web font from fonts.googleapis.com (Google Fonts) for the brand wordmark. This is a static resource request and does not transmit any of your bookmark or AI data.

What we do not do

We do not sell, rent, or share your data with anyone.
We do not run analytics or telemetry. There is no usage tracking inside the Extension.
We do not collect personally identifiable information.
We do not use your data for credit determination, lending, or any unrelated purpose.

Permissions we request and why

bookmarks — required to read and modify your Chrome bookmarks, which is the Extension’s core function.
storage — required to save your preferences, tag definitions, and AI configuration locally.
tabs — required to open bookmark URLs in the current or a new tab, and to read the active tab’s title/URL inside the popup so you can confirm AI suggestions before saving.

Your control

Disabling AI in Settings stops all AI-related network requests immediately.
Removing the Extension deletes all data stored under chrome.storage.local. Your Chrome bookmarks themselves remain untouched.
