How we handle your details

Headline Site Calculator results run in your browser. Your details and site inputs are sent only when you take an explicit action: emailing the full screening report or using the optional site map’s search and route-profile buttons.

At a glance

  • Site Calculator figures are computed in your browser and are not sent anywhere until you act.
  • The optional site map passes your searched address and route points through our server to LINZ; we keep no copy.
  • Emailed reports go through Resend, which processes them in the United States and retains email data for about 30 days.
  • We keep an active enquiry for up to 24 months after the last contact, then delete it from active records.
  • Your details are never added to a mailing list or used for unrelated marketing.
  • Page views are counted with Vercel Web Analytics, without third-party cookies or cross-site tracking.

Who collects it

Water Siphon Limited (NZBN 9429048891585) runs this Siphonic Systems website and handles its enquiries. Tom Gardiner, its director, is your contact for the details you submit through the site screening report form. Our address is 824 Old North Road, Waimauku, Auckland 0882.

What is collected

Before you submit, the Site Calculator values stay in your browser — the optional site map described below is the one exception. To email the full screening report, we collect your name, email, optional phone number, site label, the measurements used in the screen and any optional note about what you would like to improve. If a map view is available, the report also includes that view and any route you drew.

The optional site map

If you use “Find the route on a map”, the address you search and the route points you profile are sent to our server, which passes them to Toitū Te Whenua Land Information New Zealand (LINZ) to return address matches and ground elevations. We keep no copy — the lookups pass through and are not stored by us. Our hosting provider (Vercel) and LINZ keep operational request logs under their own privacy policies, which govern what those logs contain and how long they are retained. The map imagery itself loads directly from LINZ, so the map area you are viewing is visible to LINZ the way any map website is; your typed address and your route points are never part of those imagery requests.

Why it is collected

To email your screening report, let Siphonic Systems follow up on that site, and respond to your enquiry about the Siphonic Transfer Unit. Details are not added to a mailing list or used for unrelated marketing.

How it is held

Resend acts only as the email delivery processor. A screening PDF, including any map view you submit, is emailed to you and Tom at tom@watersiphon.co.nz. The website creates no visitor account and keeps no database copy. Resend processes the email in the United States and standard plans retain email data for approximately 30 days. Open and click tracking are disabled. Tom’s enquiry mailbox is the active enquiry record.

Visitor statistics

We count page views with Vercel Web Analytics to see which pages people use. Each record holds the page address without any query or fragment, the domain of the referring site, an approximate location, and the device, operating system and browser type. It uses no third-party cookies and no identifiers that track visitors across websites or apps. Vercel counts visitors with a hash created from the incoming request and discards visitor sessions after 24 hours.

How long it is kept

We keep an active screening report enquiry and its mailbox record while it is active and for up to 24 months after the last contact, then delete it from active enquiry records. If it becomes a contracted project or business transaction, relevant information moves into the applicable project or business records and follows the retention requirements for those records.

Seeing, correcting, or removing it

Under the Privacy Act 2020 you can ask to see the personal information we hold about you, ask us to correct it, or request earlier deletion unless Water Siphon Limited is legally required to keep particular information. Email tom@watersiphon.co.nz and say what you would like done. If you are not satisfied with our response, you can complain to the Office of the Privacy Commissioner (privacy.org.nz).
