USING THE TOOL

Terms of use.

Updated September 8, 2026. These terms describe the current PlaylistLengths preview.

The service

PlaylistLengths provides calculations from accessible YouTube metadata and tools for organizing your own viewing. By using the tool, you agree to these terms and the Privacy Policy. PlaylistLengths uses YouTube API Services; by using this API client, you also agree to be bound by the YouTube Terms of Service.

Responsible use

Use links you are entitled to access. Do not use the service to bypass account permissions, evade request limits or interfere with other users. Do not submit passwords, API keys or other secrets in playlist or feedback fields.

Estimates and availability

Calculations reflect available durations and the settings you select. Data can be cached, unavailable, changed or incomplete. Watching estimates exclude advertisements, pauses, exercises and other time outside the video content. Request limits and upstream availability can prevent a calculation from completing.

Your source content and exports

Source videos, thumbnails and titles remain associated with their respective creators and rights holders. Displaying metadata or exporting a list does not transfer rights to the underlying media. The tool does not download video or audio, and table sorting does not change the order of your playlist on YouTube.

Saved data and sharing

You choose when to save links and progress in your browser or copy a sharing link. Anyone who receives a settings link can see the source URL. You can remove saved calculations and progress using the controls described in the Privacy Policy.

Questions and changes

Use the Contact & Feedback page for questions or reports. Changes to the tool or these terms will be reflected on this page. The public operator and final hosting arrangements will be identified before public release.
