Information You Provide
When you paste a playlist URL or playlist ID, that value is sent to our API route so the service can request public playlist metadata from the YouTube Data API. The calculator does not ask for your YouTube login, Google password, or private account credentials.
Server Logs
Our hosting and security providers may process standard technical logs such as IP address, user agent, request path, timestamps, and error details. These logs help diagnose outages, prevent abuse, and keep the service reliable.
Cookies and Local Storage
The site stores your theme preference in localStorage so light, dark, or system mode can persist across visits. We use Google Analytics to understand aggregate page usage, traffic sources, and site performance so we can improve the calculator.
Third-Party Services
The calculator relies on YouTube Data API for public playlist information and may run on Cloudflare infrastructure. Those third-party services process requests under their own policies. We do not sell playlist URLs or use them to identify YouTube accounts.
Children's Privacy
This website is a general planning utility and is not directed to children. If you believe a child has provided personal information through the site, contact us so we can review the issue.
