Privacy & Cookie Policy
Last updated: May 2026
This policy explains how Online Calculators (onlinecalculators.co.uk) handles information when you use the site. We have deliberately kept data collection to a minimum.
The short version
We do not ask you to create an account. We do not collect your name, email or contact details unless you choose to email us. The calculators run in your browser - the figures you type into a calculator are processed on your own device and are not sent to us or stored.
Analytics
To understand which calculators are used and how the site performs, we use Cloudflare Web Analytics. Cloudflare Web Analytics is privacy-focused: it does not use cookies and does not fingerprint or track individuals. It collects aggregated, anonymous data such as page views, referring sites and general performance metrics. It does not build a profile of you and cannot identify you personally.
Because this analytics service uses no cookies and collects no personal data, it does not require consent under UK cookie rules.
Cookies
Online Calculators does not set its own tracking cookies. The site may use a small number of strictly necessary, technical cookies needed for it to function or to be served securely through Cloudflare. Strictly necessary cookies do not require consent.
We do not currently run advertising, and we do not use advertising or cross-site tracking cookies. If this changes, this policy will be updated and, where required, a consent mechanism added before any such cookies are set.
Search engine tools
We use Google Search Console and Bing Webmaster Tools to monitor how the site appears in search results. These tools report aggregated search performance data to us (such as which queries lead to the site). They do not place tracking cookies on your device through this site and do not identify you personally to us.
If you email us
If you contact us by email, we receive your email address and whatever you choose to include in your message. We use this only to reply and to act on any correction or suggestion. We do not add you to any mailing list.
Hosting
The site is hosted on Cloudflare Pages and served through Cloudflare's network. Like all web hosts, Cloudflare processes technical request data (such as IP addresses) to deliver the site securely and to protect against abuse. This processing is carried out by Cloudflare as part of providing the hosting and security service.
Third-party links
Some pages link to official sources such as GOV.UK or the NHS. Those sites have their own privacy policies, which will apply once you leave onlinecalculators.co.uk.
Your rights
UK data protection law gives you rights over personal data held about you. Because Online Calculators holds essentially no personal data about visitors - and none that identifies you unless you have emailed us - there is usually nothing for us to retrieve or delete. If you have emailed us and want your message and email address deleted, contact us and we will do so.
Changes to this policy
If we change how the site handles data, we will update this page and change the date above. Significant changes - such as introducing advertising - will be made clear.
