Privacy

PoolString is built to be read without an account. This page explains, in plain words, what the site stores and why.

Reading the site

You don't need to sign up or log in to read any tutorial. The site doesn't use advertising or tracking cookies.

What stays in your browser

Your color theme, your reading list and your quiz scores are saved in your own browser's storage so they are still there on your next visit. They never leave your device, and you can clear them at any time from your browser settings.

The newsletter

If you subscribe, we store your email address, the date, and the topic you signed up for. We use it only to send you new lessons. We ask you to confirm by email first, so nobody can subscribe you without your knowledge.

Every email has an unsubscribe link. Unsubscribing deletes your address from our list.

Running code examples

The "Try it yourself" editor runs code inside your browser. The code you type isn't sent to us.

Hosting

The site is served by Amazon Web Services, which keeps standard access logs (such as IP address and requested page) for security and reliability.
