Privacy policy

Last updated 14 October 2026.

We collect as little about you as we can. This page explains what we do collect, why, and what you can ask us to do with it.

Who we are

This website, www.tumblelane.com, is run by Tumble Lane, a sole trader based in Ireland. We are the data controller for the personal data described here. You can contact us about anything in this policy at tumblelane@gmail.com.

When you visit our website

Our site doesn't use cookies or advertising trackers, and it doesn't load anything from other companies' servers. Our fonts and images are served from our own site.

We use Vercel Web Analytics to count visits, so we can see which guides people find useful. It doesn't use cookies and doesn't identify you. For each page view it records the page, the site you came from, your approximate location (country, region and city), and your browser, operating system and device type. To count unique visitors without cookies, it uses a code generated from your request, which is discarded after 24 hours. We only see totals, never individual visitors. This is in our legitimate interests in understanding how our site is used. You can read more in Vercel's Web Analytics privacy information.

Our site is hosted by Vercel Inc. Like any web host, Vercel's servers automatically record technical information when your browser requests a page, such as your IP address, the page you asked for and your browser type. This is used to deliver the site and keep it secure, which is in our legitimate interests. Vercel processes this information on our behalf. Vercel is based in the United States and takes part in the EU–US Data Privacy Framework. You can read Vercel's privacy notice.

When you buy our book

Our checkout is run by Lemon Squeezy, which sells the book to you as merchant of record. That means Lemon Squeezy takes your payment, handles tax and sends you your download. It collects your payment details directly and we never see them. Lemon Squeezy's use of your information is covered by its privacy policy and buyer terms.

When you click a "Get the guide" button, the link tells Lemon Squeezy which page and which button you clicked, so we can see which pages lead to sales. This doesn't include anything about you.

Lemon Squeezy shares some order details with us: your name, email address, country, what you bought and when. We use these to provide what you paid for, help with download problems and process refunds (to perform our contract with you), and to keep the business records that Irish tax law requires (a legal obligation).

When you email us

If you email us, we'll have your email address and whatever you choose to tell us. We use it only to reply and help you, which is in our legitimate interests. Our email is provided by Google (Gmail), which stores messages on our behalf under Google's privacy policy. Please don't send us medical details about your baby. We can't give individual medical advice, and we'd rather not hold sensitive information we don't need.

Who we share data with

Only the service providers named above (Vercel, Lemon Squeezy and Google), and only so they can provide their services. We may also disclose information if the law requires it. We never sell your personal data.

Some of these providers store or process data outside the European Economic Area, including in the United States. Where they do, the transfer is protected by an approved safeguard, such as the EU–US Data Privacy Framework or the European Commission's standard contractual clauses.

How long we keep it

• Order records: for six years, as Irish Revenue rules require for business records.
• Emails: for as long as we need them to help you, and then we delete them. This is usually no more than two years after our last contact, unless they relate to an order.
• Server logs: Vercel keeps these for a short period, set by Vercel, for security and operational purposes.

Your rights

Under data protection law (the GDPR), you have the right to:

• ask for a copy of the personal data we hold about you;
• ask us to correct it if it's wrong;
• ask us to delete it, unless the law requires us to keep it;
• ask us to restrict how we use it, or object to how we use it;
• ask for your data in a portable format;
• withdraw your consent at any time, where we rely on consent.

To use any of these rights, email tumblelane@gmail.com. We'll reply within one month. If you're unhappy with how we've handled your data, you can raise a concern with Ireland's Data Protection Commission. We'd appreciate the chance to put things right first.

Children

Our site and book are written for parents and carers. They are not directed at children, and we don't knowingly collect data from anyone under 16.

Changes to this policy

If we change how we use personal data, for example by adding a newsletter, we'll update this page and the date at the top.
