Reminder MathJoin the list

Privacy

The short version: we keep your email address so we can write to you about the books and the channel, and for nothing else. You can leave at any time, and we’ll delete it if you ask.

Who we are

Reminder Math makes the Reminder Math videos and books and runs remindermath.com. For anything on this page, write to hello@remindermath.com.

What we keep

When you join the list we keep your email address and the date you joined. On the books’ form we also keep whether you confirmed with the link we sent, and if you never confirm, we never write to you. When you download a free cheat sheet and you’re new to the list, you join it straight away, and we email you a copy of the download link. If you left the list before, downloading doesn’t sign you up again. The book you pick on the form isn’t stored yet. If we start keeping it, this page will say so first.

Like every website, our server sees your IP address when you load a page. We use it only to stop people abusing the sign-up form, and we don’t store it with your email.

This site sets no cookies and runs no analytics or ads.

What we do with it

We email you about the books and the channel: sample pages, new videos and cheat sheets, when pre-orders open, and release day. We never sell your address or share it with anyone except the services below, and every email has a one-click unsubscribe.

Who handles it for us

  • Resend stores the list and sends our emails.
  • Hetzner hosts this site on a server in the EU.

When pre-orders open, payments will go through a payment provider, and we’ll name it here before then.

Our YouTube channel and Discord server are run by those platforms, and their own privacy policies apply there.

How long we keep it, and your choices

We keep your address until you unsubscribe or ask us to delete it. You can ask to see what we hold about you, correct it or have it deleted by writing to hello@remindermath.com. We’ll answer within a month.
