Privacy policy.

Who's responsible

This site and the mailing list behind it are run by Math I Like It, an independent publishing project based in Poland. It's a one-person operation, not a company with a support department. For anything on this page — questions, requests, complaints — write to privacy@mathilikeit.com. A real person reads it.

What we collect

Only what you hand over, plus the minimum our email provider needs to do its job:

• Your email address — the one you type into the signup form. It's the only field we ask for.
• Your consent record — the date, time and IP address of your signup, plus your confirmation click. We're required to be able to prove you actually asked for these emails, and this is how.
• Basic email statistics — whether an email was opened and whether a link was clicked. We use this to work out which emails are worth sending, not to build a profile of you.

We don't run analytics on this site. There's no Google Analytics, no Facebook pixel, no tracking of what pages you read. If you never fill in the form, we never learn you were here.

Why we're allowed to have it

Because you said yes. The legal basis is your consent (Article 6(1)(a) GDPR), given when you submit the form and confirm it by clicking the link in the confirmation email. You can withdraw it at any time, and doing so is as easy as giving it — one click, bottom of any email. Withdrawing doesn't affect anything we sent before.

Who else sees it

Three companies, each doing one job:

• EmailOctopus — stores the list and sends the emails. UK-based; data held on Amazon Web Services in the EU region.
• Zoho — hosts our mailbox, so it sees any email you write to us directly. EU data centre.
• Cloudflare — serves this website.

Nobody else. We don't sell, rent, or trade your address, and we don't pass it to advertisers or other publishers. If that ever changes, it will change with your explicit consent first, not quietly on this page.

How long we keep it

Until you tell us to stop. Unsubscribe and your address is removed from the mailing list; we keep a minimal record that you unsubscribed, so we don't accidentally email you again. Ask for deletion at privacy@mathilikeit.com and we remove everything.

Your rights

Under GDPR you can ask us to show you what we hold, correct it, delete it, hand it over in a portable format, restrict what we do with it, or object to it entirely. You can also withdraw consent whenever you like. One email to privacy@mathilikeit.com covers all of it, and we'll get back to you within 30 days.

If you think we've handled your data badly and we haven't fixed it, you can complain to your national data protection authority. In Poland that's the President of the Personal Data Protection Office (UODO).

Children

Our books are for kids. This mailing list is not. The signup form is meant for parents, guardians and teachers, and we don't knowingly collect email addresses from children. If your child has signed up without you knowing, email privacy@mathilikeit.com and we'll delete the address straight away.

Cookies

This site doesn't set any cookies of its own and doesn't track you across the web. The signup form is loaded from EmailOctopus, and their script may store a small amount of data in your browser so the form knows whether you've already submitted it. Nothing on this site follows you anywhere else.

Changes to this page

If we change how any of this works, we'll update this page and change the date below. If the change is significant — new data, new purpose, a new company handling it — we'll tell you by email rather than hoping you re-read this page.
