This website
plainsums.co.uk is a static site. It sets no cookies and shows no advertising. Our hosting provider, Netlify, processes standard request data (including IP addresses) to deliver and secure the site; we don't use it to identify visitors.
Visitor counting
No visitor-counting or analytics script runs on this site at the moment. If we switch one on it will be GoatCounter, a cookie-free service hosted in the EU, and this page will say so and offer an opt-out.
When you email us
We keep your email and our reply for as long as we need to deal with your question and for a reasonable period afterwards, on the basis of our legitimate interest in answering you and keeping a record of what we said. We don't add you to any mailing list.
When you buy a spreadsheet
Purchases happen on Etsy, which is a separate data controller: Etsy handles payment, delivers the download, and shows us your name, the item bought and any messages you send through Etsy. We use that only to deliver the file, send updated versions when you ask for one, and deal with problems. Etsy's own privacy policy explains what it does with your data.
Your rights
Under UK data protection law you can ask what personal data we hold about you, ask for it to be corrected or deleted, or object to our use of it. Email us and we'll respond within a month. If you're unhappy with how we handle your data you can complain to the Information Commissioner's Office at ico.org.uk.
