Privacy Policy

Overview

Sanctum is a Chrome extension that blocks known adult domains and custom domains added by the user. This policy explains what data the extension uses and how it is handled.

Information Sanctum handles

• Custom blocked domains: domains you type into the popup or add from the current tab.
• Current tab domain: the popup reads the active tab URL only to show the current domain and let you block it.
• Quote rotation state: a small local value that helps rotate encouragement quotes without repeating until the quote list has cycled.

Sanctum does not ask for your name, email address, account credentials, payment details, or other profile information.

How information is stored

Custom domains are stored with Chrome extension storage so Sanctum can recreate blocking rules when the browser starts. Depending on your Chrome settings, Chrome may sync extension storage through your Google account. Sanctum does not operate its own server for this data.

Quote rotation state is stored locally in the browser.

How information is used

Sanctum uses custom blocked domains to create Chrome declarativeNetRequest rules that redirect matching pages to the bundled blocked page. It uses the active tab domain only when the popup is opened and the current-tab blocking feature is shown.

Private windows

Chrome does not allow extensions to run in Incognito windows unless the user enables that access from Chrome's extension details page. If enabled, Sanctum uses the same stored block settings to apply blocking rules in private windows.

Sharing and selling

Sanctum does not sell personal information. Sanctum does not share custom domain lists, browsing activity, or quote state with advertisers, analytics providers, or external services.

Remote code, analytics, and ads

Sanctum does not load remote code, run analytics scripts, use tracking pixels, or display ads.

Permissions

• declarativeNetRequest: creates browser-level blocking and redirect rules.
• declarativeNetRequestWithHostAccess and host permissions: allow blocking rules to apply to matching sites.
• storage: saves custom blocked domains and quote rotation state.
• tabs and activeTab: read the current tab domain when the popup is opened so you can block that domain.

Deleting data

You can delete Sanctum's stored extension data by removing the extension from Chrome. You may also clear extension data from Chrome's browser data or sync settings.
