Privacy policy
The short version: this site doesn't ask for your name or email, doesn't have accounts, and doesn't run ads or ad trackers. A few pages load charts and videos from other companies, and those companies have their own privacy policies.
What this site collects
Nothing about you. There are no sign-ups, no forms that send anything to me, and no analytics or ad trackers. The calculators run in your browser, and what you type in them stays there.
Who else loads on these pages
- Cloudflare hosts this site. Like any web host, its servers see basic request details such as your IP address and browser so they can deliver the page and block attacks.
- TradingView provides the charts, prices and earnings dates on the stock pages. Those load from TradingView's servers and can set TradingView's own cookies, under TradingView's privacy policy.
- YouTube serves the video thumbnails, and sees you once you click through to watch a video, under Google's privacy policy.
That's the whole list.
9to5 Studio Insights (my own YouTube tool)
9to5 Studio Insights is a private tool I use to study my own channel. It signs in to Google with my account only, and nobody else can use it.
- What it reads: my channel's videos, playlists, analytics (views, watch time, retention, traffic sources), comments, and my videos' caption files, through the YouTube Data API and the YouTube Analytics API.
- What it changes: only my own playlists, and only when I tell it to (for example, reordering one).
- Where the data goes: it's stored on my own computer. To write its reports, the tool sends parts of that data, such as video titles, stats and transcripts, to Anthropic's Claude API. It isn't sold, shared with anyone else, or used for ads.
- Google's rules: the tool's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements, and the YouTube Terms of Service. You can see or remove the tool's access to a Google account at myaccount.google.com/permissions.
