Terms & Conditions

1. Agreement to Terms

By accessing or using CheckPlaylistLength.com (the "Website" or "Service"), you agree to be bound by these Terms and Conditions ("Terms") and acknowledge that your use is also subject to the YouTube Terms of Service and the Google Privacy Policy. If you do not agree with any part of these Terms, you must discontinue use of the Website immediately.

2. Description of Service & API Usage

CheckPlaylistLength.com provides free server-side web calculation tools that allow users to calculate total runtimes, speed-adjusted durations, study schedules, and analytics for publicly available and unlisted YouTube playlists.

The service operates by querying the official YouTube Data API v3 on your behalf. Service availability is subject to Google YouTube API quota limits (which reset daily at midnight Pacific Time). While we strive for 100% uptime, calculations may be temporarily unavailable if daily quotas are exhausted.

3. Intellectual Property Rights

A. Our Intellectual Property

The website design, layout, custom code, logos, calculations, algorithms, and editorial text published on CheckPlaylistLength.com are the exclusive property of CheckPlaylistLength.com and are protected by applicable copyright and intellectual property laws.

B. Third-Party Trademarks & Content

"YouTube" is a registered trademark of Google LLC. All video titles, thumbnails, channel names, and durations displayed in calculation results belong to their respective creators and copyright owners on YouTube. CheckPlaylistLength.com makes no claim of ownership over third-party video metadata fetched via public API requests.

4. Permitted and Prohibited Uses (Fair-Use Policy)

You are granted a revocable, non-exclusive license to use the Website strictly for personal, educational, or professional planning. To ensure server reliability for all visitors, you agree not to:

• Engage in automated scraping, mass robotic requests, or denial-of-service (DoS) attacks that overburden our servers.
• Exceed our standard per-IP rate limits (30 calculation requests per minute) or attempt to bypass security controls.
• Use the Website for any unlawful purpose or in violation of any local, national, or international regulations.
• Frame or mirror any part of the Website within another commercial service without express written permission.

5. Accuracy of Data and Calculations

While we apply rigorous mathematical precision to duration calculations, playlist metadata is sourced from YouTube Data API v3 in real time. Discrepancies may occasionally occur when:

• Videos within a playlist are deleted, hidden, geo-blocked, or set to private by their creators (these are excluded from totals and reported as skipped).
• YouTube alters internal video metadata or video availability.
• Live streams or premiere placeholders with indefinite durations are embedded in the playlist.

Calculated study dates and time savings are intended as estimations to assist personal planning and are provided without warranty.

6. Disclaimer of Warranties

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL CHECKPLAYLISTLENGTH.COM, ITS DEVELOPERS, OR OPERATORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
