Privacy Policy

TaxQuarters is built so your tax figures never leave your device. Our tools calculate entirely in your browser. This page explains the little we do collect (mainly: your email address, only if you choose to sign up for deadline reminders) and your rights over it.

Who we are

TaxQuarters is operated by Ascensial Ltd (company number 16089646), registered in England and Wales. Registered office: 124 City Road, London, EC1V 2NX. Ascensial Ltd is the data controller for this site. Contact [email protected].

What we collect, and why

The tools themselves collect nothing

Everything you type into a TaxQuarters calculator (income figures, dates, wave, results) is calculated in your browser and is never sent to us or stored anywhere. Closing the tab clears it.

If you sign up for deadline reminders

Email reminders aren't switched on yet. Once they are: if you choose to enter your email address, we'll send your email address, your MTD wave (1, 2 or 3) and your quarter basis (standard or calendar) to our email provider, MailerLite. We never send the income figures or dates you entered into a tool; reminders are matched to your situation using only the wave and quarter basis. You'll confirm your subscription by clicking a link in a confirmation email (double opt-in) before you receive anything else, and every reminder email will include a one-click unsubscribe link.

Site usage

Our hosting provider, Cloudflare, keeps standard technical logs (for example, IP address) for security and performance. This is already active, as it is for any hosted website. We also plan to use Google Analytics to understand overall site usage (pages visited, approximate location, browser type); when that's switched on, we'll update this section and the cookies section below.

Legal basis

Who we share data with

We never sell your data, and we never share it with software vendors or affiliate partners.

How long we keep it

Email addresses are kept for as long as you're subscribed. If you unsubscribe, we keep a record of your email on a suppression list rather than deleting it straight away (this is what stops you being re-added by mistake) for as long as we run this reminder service. If you'd rather we erased your email completely instead, see Your rights, below.

Your rights

Under UK GDPR, you have the right to: access the data we hold about you; have it corrected; ask us to delete it; restrict or object to how we use it; and take it elsewhere (portability). Email [email protected] and we'll act on it. You can also complain to the Information Commissioner's Office if you think we've got something wrong.

Cookies

We don't use marketing or advertising cookies today. Once Google Analytics is switched on, it will set a small number of cookies to distinguish site visitors. We'll update this section and add a cookie-consent option at that point. If we introduce display advertising in future, the same applies: this policy will be updated first and consent requested where required.

Children

TaxQuarters is aimed at adults running a business or letting property, and isn't directed at children. We don't knowingly collect data from anyone under 18.

Changes to this policy

We'll update the "last reviewed" date below whenever this policy changes, and note anything material on this page.
