Privacy Policy

Last updated: October 20, 2026

Thank you for using Bookmark Resume for YouTube (the "Extension"). This Privacy Policy explains how the Extension handles your information. By using the Extension, you agree to the practices described here.

Data Collection & Handling

Information Stored Locally

• Playback Progress: For each bookmarked video, the Extension stores the last position in seconds, the video duration, and the time of the last update in chrome.storage.local on your device. This data is used only to resume playback.
• Settings: Whether saving is enabled, the heartbeat interval, and whether bookmark titles are updated are stored in chrome.storage.sync so they can follow your Chrome profile.
• Runtime State: Short-lived state is kept in chrome.storage.session and is cleared when the browser session ends.
• Bookmark Titles: When title updates are enabled, the Extension renames matching bookmarks with a percentage prefix, for example [43%] Original title. Normal use does not modify bookmark URLs.
• Legacy Migration: On the first run after upgrading from an older version, existing time parameters are read from bookmark URLs, copied into local storage, and removed from those URLs once. This migration is described on the introduction page.

Information We Do NOT Collect

The Extension does not collect, track, or sell your browsing history, personal identity, IP address, bookmarks, passwords, viewing history, or usage analytics. It has no backend infrastructure, no analytics code, and makes no network requests.

Network Activity

The Extension does not transmit any data. All processing happens locally in your browser. There are no remote servers, third-party APIs, accounts, or tracking pixels.

Chrome Web Store Privacy Disclosure

The developer declares that Bookmark Resume for YouTube:

• Does not collect or use your personal data outside of its core functionality.
• Does not sell your data to third parties under any circumstances.
• Does not use or transfer your data for purposes unrelated to the item's core functionality.
• Does not use or transfer your data to determine creditworthiness or for lending purposes.

Permissions Justification

• bookmarks — Required to read the bookmark tree, match bookmarks to the current video, perform the one-time legacy migration, and optionally update bookmark titles. The Extension never creates, moves, or deletes bookmarks.
• storage — Required to save playback progress locally, sync settings, and keep short-lived runtime state.
• sidePanel — Required to display the status and settings interface in Chrome's side panel.
• Host Permissions (www.youtube.com, m.youtube.com) — Required to read the video player's current time, duration, and page title. The Extension does not access any other website.

Data Retention & Deletion

Playback progress remains in chrome.storage.local until you clear the Extension's data or remove the Extension. Settings follow your Chrome Sync profile and can be removed in the same way. The Extension does not retain any data on a server.

Children's Privacy

The Extension does not knowingly collect any information from anyone, including children under 13.

Changes to This Policy

If this privacy policy is updated, changes will be posted on this page with a revised date.
