Privacy policy

Short version: this site has no accounts, no forms, no ads and no tracking cookies. The calculators run in your browser and nothing you type into them is sent anywhere.

Who runs the site

Home Water Plain is run by Ajay Singh, an individual based in the UK. For anything to do with your data, email [email protected]. Because the site is run from the UK, UK data protection law (the UK GDPR and the Data Protection Act 2018) applies to how your information is handled, wherever you're reading from.

What's collected

When you visit

The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical details such as your IP address and browser type to deliver pages and protect the site from abuse. I don't get a list of visitors' IP addresses. Cloudflare's own privacy policy explains how it handles that data.

If visitor statistics are switched on, they come from Cloudflare Web Analytics, which counts page views without cookies and without building a profile of you. No Google Analytics, no advertising pixels, no social media trackers.

The calculators

The water softener size calculator and the running cost calculator do all their sums in your browser. The numbers you enter aren't sent to me or anyone else, and they aren't saved once you leave the page.

When you email

If you email me, I'll have your email address, your name if you include it, and whatever you write. I use it to reply and, if you've reported a mistake, to fix the page. I don't add you to a mailing list, and I don't sell or share your email. Emails are kept for up to 12 months after the conversation ends, then deleted, unless you ask me to delete them sooner.

Cookies

This site doesn't set cookies. That's why there's no cookie banner.

Links to retailers and other sites

Pages link to official sources such as the EPA and USGS, to manufacturers, and in future to retailers such as Amazon. Once you follow a link, you're on someone else's site and their privacy policy applies. Retailers may set their own cookies when you arrive from an affiliate link so they can credit the sale. The affiliate disclosure explains those links.

Your rights

You can ask to see the personal data I hold about you (in practice, any emails you've sent), to have it corrected, or to have it deleted. Email [email protected] and I'll respond within one month. If you're unhappy with how your data has been handled, you can complain to the UK Information Commissioner's Office at ico.org.uk.

Changes

If anything here changes, for example if a contact form is ever added, this page will be updated first and the date at the top will change.
