Privacy Policy
Effective September 29, 2026. GICH Holdings LLC ("we") runs plumbingfixtureunits.com. Questions: support@plumbingfixtureunits.com.
What we collect
- Email address — to sign you in and contact you about your account.
- Calculations — the inputs you enter and the results, saved to your usage list so you can reopen them, and as a record of what the calculator returned.
- Purchase records — date, number of credits, amount and Stripe reference numbers, plus Stripe's card fingerprint (an anonymous code for a payment card, not the card number) so the Refund Policy's one-refund-per-year rule applies per person as well as per account. We never see or store your card number. Payment and billing details are collected directly by Stripe and Link (the merchant of record for the sale), under Stripe's privacy policy and Link's privacy policy. Link may delete its payment records at your request.
- Technical logs — IP address, browser type and request times, kept by our server for security and troubleshooting.
Cookies and Do Not Track
We use one cookie to keep you signed in. No advertising or third-party tracking cookies, and no analytics service. We don't track you across other websites, so browser "Do Not Track" signals don't change anything here.
How we use it
To run the Service, keep your credit balance and usage list, send sign-in links and account emails, prevent abuse, answer support requests, and meet legal and tax obligations. We don't sell or rent personal information, and we don't share it for advertising.
Who else handles it
Our hosting provider (DigitalOcean), our email provider (Microsoft 365), and Stripe and Link (payments). We may disclose information if the law requires it.
How long we keep it
Account and usage records are kept while your account is open. Purchase records are kept as long as tax and accounting rules require (generally at least 7 years). Server logs are kept for up to 90 days.
Your choices
You can ask to see, correct or delete your information by emailing us from your account address. Deleting your account removes your usage list and unused credits; we keep purchase records the law requires. Depending on where you live, you may have additional rights under state privacy laws; we honor valid requests.
Security
Traffic is encrypted (HTTPS). Sign-in links and API keys are stored only as one-way hashes.
Children
The Service is for adults working in the trades and is not directed to children under 13.
Changes
We'll post changes here with a new date and email account holders about material changes.
