Privacy Policy
How we handle the information you give us.
Last updated: October 2026
Information We Collect
This policy covers Daly City Water Filtration, which provides water testing, filtration and related services in Daly City, California, across San Mateo County and the surrounding area.
When you call or book a visit, we collect your name, phone number, service address and the best times to reach you, along with details about your home's water, plumbing and any existing equipment.
During visits we record water readings, laboratory results you ask us to arrange, and notes about your plumbing and equipment. When you use this website, our hosting provider may record technical details such as IP address, browser type and pages viewed.
How We Use Your Information
We use your information to schedule visits, check your water and plumbing, prepare written prices, install and service equipment, send reminders you have asked for, answer questions and keep a record of work at your home.
We may also use general, non-identifying website information to improve the site and keep it working.
Cookies and Tracking
This website does not use advertising cookies. Our hosting provider may use strictly necessary technical cookies or logs to deliver pages securely and prevent misuse.
If we add analytics or similar tools later, we will update this policy.
How We Share Information
We do not sell your personal information. We only share it when needed to do the work, for example with a certified laboratory testing your sample, a manufacturer registering a warranty, or a supplier ordering parts.
We may also share information if the law requires it or to protect our rights, our customers or the public.
Data Security
We take reasonable steps to protect your information and limit access to the people who need it. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.
Your Choices and Rights
You can ask what information we hold about you, ask us to correct it, or ask us to delete it where we are not required to keep it. You can also ask us to stop sending reminders at any time.
To make a request, call us at (650) 300-3248.

This site may link to other websites, such as water quality reports, laboratories or manufacturers. We are not responsible for their content or privacy practices.
Children's Privacy
Our services are for adults responsible for a home or business. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this policy from time to time. The date at the top of this page shows the latest version, and continuing to use the site or our services means you accept it.
