Calculator inputs

Your entered household and water values are calculated in your browser. This version does not send those inputs to our server, save them in a database, put them in page URLs or retain them in local browser storage. Reloading the page resets the calculator.

Analytics and cookies

We have not installed an advertising pixel or analytics service. Product clicks trigger a local event containing the product ID and whether its link is sponsored. No reporting service is connected to that event. The calculator itself does not set cookies.

Hosting and account access

The hosting platform processes page requests and may use technical logs, IP addresses and cookies for delivery, security and sign-in. The public calculator does not require a visitor account. The calculator’s local processing does not mean the hosting service receives no technical information.

Manufacturer links

Opening an external product link sends you to the manufacturer or its link provider, where that provider’s privacy and cookie practices apply. We do not append your calculator inputs to these links. Current product links do not contain affiliate tracking configured by us.

Contact and privacy questions

Email contact@watersystemsizing.com for questions, corrections or privacy inquiries. Email sent to this address is forwarded through Porkbun to the site operator’s inbox. Your email address and message content are processed by the email providers and received by the operator to respond to your inquiry. Avoid sending sensitive personal information or unredacted water reports.

Changes to this notice

This notice describes the current version. It will be updated before analytics, affiliate tracking or contact forms change how the site handles information.
