Privacy
Last updated 6 September 2026. The short version: we collect almost nothing, and the income figures you type into the checker never leave your device.
The scope checker
The checker on the home page runs entirely in your browser. The income figures and answers you enter are never transmitted to us, never stored, and never seen by anyone. Close the page and they are gone. We have no way of knowing what you typed.
When you buy
Payments are processed by Stripe. Stripe collects your name, email address and payment details in order to take the payment. We never see or store your full card details.
We receive your email address and the fact that you bought the product. We use this only to provide access, handle refunds, and contact you if a deadline in the calendar changes materially. We do not sell it, and we do not send marketing unless you separately ask us to.
Stripe has its own privacy policy, available at stripe.com.
The calendar itself
When your calendar application refreshes the subscription, our host receives the request in ordinary server logs. We do not use this to build a profile of you.
Cookies and tracking
This site sets no cookies of its own and uses no analytics or advertising trackers. Fonts are loaded from Google Fonts, which means Google's servers receive a request from your browser when the page loads.
How long we keep things
Purchase records are kept for six years, because HMRC requires business records to be retained. Support emails are deleted once resolved and no longer needed.
Your rights
Under UK GDPR you can ask for a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it where we are not required to keep it. Email hello@mtdcalendar.co.uk.
If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office at ico.org.uk.
Who we are
MTD Calendar, 4 Telford Way, Kettering, NN16 8UN, United Kingdom. We are the data controller for the limited personal data described above.
