The short version is simple: you can use this calculator without creating an account, and we do not want your personal data. The page is meant to answer one practical question, which is how long a YouTube playlist or set of videos will take to watch. To do that, the calculator needs the YouTube link or ID you paste. It does not need your name, your YouTube login, your viewing history, or anything like that.
What happens when you press calculate
Your browser sends the text from the calculator form to our calculation endpoint. The code extracts playlist IDs and video IDs, asks the YouTube Data API for public duration information, and then returns the total time back to the page. That is the normal flow. We are not building a profile of the playlists you check, and we are not trying to connect one calculation to another.
What we do not store on purpose
We do not ask you to register. We do not store a saved account profile. We do not add Google Analytics, ad scripts, or social tracking pixels to the first version of this site. We also do not keep a permanent list of raw playlist URLs as a user history. If that ever changes in the future, this policy should change first, not after the fact.
If you paste your own YouTube API key
The API key field is there for people who want to run a request with their own YouTube Data API key. If you use it, the key is sent with that calculation request and is not shown on the page, saved as public content, or written into a long-term profile. You should still treat any API key like a password: use a restricted key, rotate it if you think it was exposed, and do not paste a key that gives access to unrelated services.
Logs and troubleshooting
Like most websites, the hosting platform may process basic technical information such as IP address, browser request metadata, and timestamps so the site can load and errors can be diagnosed. Inside the calculator code, error logs are intentionally kept narrow: the error type, the time, and the number of IDs parsed. The raw text you pasted and any API key are not supposed to be written into those application logs.
Services involved
The calculator relies on YouTube Data API responses to read public playlist and video duration data. The site is also served by a hosting provider, which has to process normal network traffic to deliver the page and the API response. We do not control YouTube, Google, your browser, your internet provider, or the hosting platform, so their own policies may also apply to the parts of the request they handle.
If something in this policy feels unclear, or if you notice the calculator behaving in a way that does not match this page, email contact@youtubeplaylistlength.org.
