This policy explains what personal data House of Calculator (houseofcalculator.com) handles and why. We have kept it short because the site collects very little.
Who we are
The data controller is House of Calculator, operated by [operator name and address to be completed before launch]. You can contact us using the contact form. This policy is written with UK GDPR, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations (PECR) in mind.
The short version
- There are no accounts, no forms and no advertising. If you accept analytics cookies in our banner, we use Google Analytics to count visits. If you reject them, no analytics cookies are set.
- Calculator inputs are processed locally in your browser. They are not transmitted to us.
- We save one preference, your currency choice, in your browser’s local storage.
- Our hosting provider and content delivery network (CDN) keep technical logs, and pages load fonts from Google Fonts.
What data we handle
| Data | Why | Where it is held |
|---|---|---|
| Numbers you type into calculators | To show you a result | Your browser only. Not sent to us. |
| Currency preference | To remember your choice | Your browser’s local storage. We cannot access it. |
| Analytics data, only if you accept: pages viewed, approximate location, device and browser type, how you arrived, and a random identifier held in a cookie | To understand which calculators and guides are used and to improve the site | Google Analytics (Google) |
| Technical request data: IP address, browser user agent, requested URL, timestamp | To deliver pages, keep the site secure and diagnose faults | Server logs at our hosting provider and CDN |
| IP address and browser details sent to Google when fonts load | To load the site’s fonts | |
| Messages you send through the contact form: name if given, email address and message | To reply to you | Our email system |
Lawful bases
For server logs and security, we rely on legitimate interests under UK GDPR: keeping the website available, secure and working properly. We have considered your interests and the data is limited and used only for those purposes. If you contact us, we rely on legitimate interests to read and reply to your message. For Google Analytics we rely on your consent, which you can give or withdraw at any time through the cookie banner or the “Cookie settings” link in the footer.
Cookies and local storage
We set analytics cookies only if you accept them. If you reject them, or ignore the banner, we set none. If you accept, Google Analytics sets cookies named _ga and _ga_ followed by an identifier, which last up to two years. We also store your cookie choice and your currency preference in your browser’s localStorage. These are not cookies, they stay on your device, and we cannot read them. You can change your choice at any time with the “Cookie settings” link in the footer, and you can remove everything by clearing your site data in your browser settings.
Third parties
Hosting and CDN. Our hosting provider and CDN process request data on our behalf to deliver the site and protect it from abuse.
Google Analytics. If you accept analytics cookies, Google Analytics 4 collects usage data about your visit (pages viewed, approximate location, device and browser type, and how you arrived) and sends it to Google. Google Analytics does not log or store full IP addresses. We use it only to understand and improve the site, not for advertising. Google’s own privacy information is available at policies.google.com/privacy.
Google Fonts. Pages load fonts from Google Fonts. When they do, your browser contacts Google’s servers, so your IP address and browser details are sent to Google. Google’s own privacy information is available on its website at policies.google.com/privacy. We may self-host fonts in future so that this no longer happens.
International transfers
Our hosting provider, CDN and Google may process data outside the UK. Where this happens, we expect the providers to use safeguards recognised under UK data protection law, such as the UK’s international data transfer arrangements.
How long we keep data
Server logs are kept by our providers only for as long as needed for security and delivery, in line with their standard retention periods. Messages to us are kept for as long as needed to deal with your query and then deleted. Analytics data is kept in Google Analytics for no longer than 14 months. Local storage stays on your device until you clear it.
Your rights
Under UK data protection law you have the right to access your personal data, have it corrected, have it erased, restrict or object to its use, and to data portability, where these apply. Because we hold so little data and cannot identify visitors from it, we may not be able to link a request to a particular person. To make a request, use the contact form. You also have the right to complain to the Information Commissioner’s Office (ICO) at ico.org.uk.
Children
The site is not directed at children under 13. There are no accounts, and we do not knowingly collect personal data from children.
External links
Our pages and guides may link to other websites, such as GOV.UK. We are not responsible for their content or privacy practices, so please read their policies.
Changes to this policy
We may update this policy from time to time and will change the date at the top when we do. If we add advertising or email features, we will update this policy first and, where the law requires it, ask for your consent before using them.
