Privacy policy

Last updated: 9 November 2026

Sheet Happens ("we", "us") runs this website. This page explains what information is collected when you use it and how it is used.

What we store on your device

When you work through a lesson, the site saves your progress and the contents of the practice spreadsheet in your browser's local storage. This stays on your device. We do not receive it, and you can remove it at any time by clearing your browser's site data or using the "Reset this lesson" button.

Accounts

You do not need an account to use the site and we do not currently collect names, email addresses or passwords. If we add optional accounts in future, we will update this policy before collecting any such information.

Server logs

Like most websites, our web host automatically records technical information when a page is requested, such as IP address, browser type, the page requested and the time. This is used to keep the site running securely and is kept only for as long as the host's standard log retention allows.

Advertising and cookies

This site is funded by advertising and may show ads provided by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's previous visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.

You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and you can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info.

Where required by law, such as for visitors in the European Economic Area and the United Kingdom, we ask for your consent before using cookies for personalised advertising, and you can change your choice at any time.

Analytics

We may use privacy-conscious analytics to see which lessons are used and where people get stuck, so we can improve them. If we do, the details will be listed here.

Children

The site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Depending on where you live, you may have rights over personal data held about you, including to access, correct or delete it. Because we hold very little personal data, most of this is controlled by you through your browser settings.

Changes to this policy

If we change this policy we will update the date at the top of the page.
