Privacy & cookies

This policy explains what information calctool.co.uk ("CalcTool", "we") collects and why. CalcTool is run by Fynlo Digital in the United Kingdom, which is the data controller for this site.

What you type into calculators

Calculators run entirely in your browser. Figures you enter are not sent to us and are not stored on any server. Some tools put your inputs in the page address (for example ?salary=35000) so you can bookmark or share a result; that address stays on your device unless you share it.

Information collected automatically

• Hosting logs. Our host, Netlify, processes your IP address and basic request details to deliver pages and protect the site from abuse.
• Currency converter. When you use it, your browser fetches exchange rates from frankfurter.app, which will see your IP address.
• Advertising. If adverts are shown, Google AdSense and its partners may use cookies or similar technology to show ads and measure them. Where the law requires it we ask for your consent first, and you can change your choice at any time using the privacy settings link shown by the consent message. See how Google uses information from sites that use its services and manage personalised ads at Google Ad Settings.

Cookies and local storage

• Essential: your light or dark mode choice is saved in your browser's local storage. It never leaves your device.
• Advertising (only with consent where required): cookies set by Google and its ad partners, as described above.

Links to other sites

Some pages link to other websites, including partners who may pay us a commission. Their own privacy policies apply once you leave CalcTool.

Your rights

Under UK data protection law you can ask for access to, correction of or deletion of personal data we hold about you, and you can complain to the Information Commissioner's Office (ico.org.uk). As we don't collect calculator data, we usually hold nothing about you. Contact us at fynlodigital@gmail.com.

Children

CalcTool is a general audience site and doesn't knowingly collect information from children.

Changes

We'll update this page if anything changes, with a new date at the top.
