NoDup

Privacy Policy

Effective September 23, 2026 · Published by Yel

NoDup matches links with tabs already open in Chrome. This happens on your device. The extension does not send your browsing data to Yel or any external server.

What the extension uses

NoDup reads open-tab URLs, tab and window identifiers, tab status, and navigation events to identify an existing match and distinguish links opened from another app, from another webpage, or from the address bar of a newly created tab. URLs may contain query parameters or other sensitive information. NoDup uses them only for its tab-reuse features.

NoDup does not read page contents, access Chrome's saved browsing-history database, or use cookies or password APIs. It has no accounts, analytics, advertising, or remote code.

What stays in Chrome

• Your settings, language choice, and excluded hostnames are saved locally until you change them or uninstall NoDup.
• Temporary navigation records, candidate URLs, tab identifiers, and timestamps are held in Chrome session storage. Matching records normally become ineligible after eight seconds and are removed when the next event is processed.
• The most recently reused URL, latest Undo details (including tab placement), temporary bypass state, and up to 12 diagnostic reason codes with timestamps remain in session storage until the browser session ends or the extension is reloaded or disabled. Undo eligibility expires after 60 seconds. New-tab eligibility records persist in session storage until first navigation or tab closure.
• Cumulative reuse counts, estimated time saved and up to 20 completed page-load durations per hostname, for up to 100 recently sampled hostnames, are saved locally across browser sessions. Samples contain hostnames and durations, but no full URLs, paths, query parameters or page contents. Subdomains are treated separately. Temporary load start times and document identifiers are held in session storage. Estimates use the median of eligible durations for the matching hostname, or a 3-second fallback until that host has five samples, and may differ from actual time saved.

NoDup does not use Chrome Sync storage. The publisher cannot access this locally held information.

Sharing and your controls

NoDup does not sell, transmit, or share extension data. It does not use data for advertising, credit decisions, or purposes unrelated to tab reuse.

You can pause automatic reuse, allow the next duplicate, or exclude a hostname in the popup. Pausing stops automatic reuse; the extension may still process navigation events locally. Disable or remove the extension in Chrome to stop all processing. Uninstalling removes its stored settings, local statistics and session data.

NoDup follows the Chrome Web Store User Data Policy and its Limited Use requirements. Information available through Chrome APIs is used only to provide the tab-reuse features described here.
