What this site does with your data
The calculators run in your browser and themselves send nothing you type to us. Apart from loading pages, only the paid whole-kitchen sheet talks to our server and to PayPal. Our code sets no cookies, runs no analytics and has no accounts.
What runs in your browser
Every tool on this site runs in your browser. A calculator itself sends nothing you type to us.
A calculator keeps what you enter in the page's address (the mail merge tool does not), so a link you copy, bookmark or share carries it. Reloading or opening that address sends it to Cloudflare like any page request; none of our server code reads it.
The mail merge tool opens your PDF and list on your own device. They are not uploaded, and nothing in them is sent anywhere.
What is stored on your device
Only the cabinet door tool's whole-kitchen sheet stores anything, in your browser's local storage:
hth:licence:…your licence: the product, the PayPal order id, PayPal's test or live mode, and when it was issued;hth:order:…the PayPal order id of your latest purchase or restore;hth:notpaid:…an order id our server reported as not paid;hth:kitchen:…your list of cabinet openings, with its frame and joint settings.
They are kept in this browser; clearing its data removes them.
What is sent anywhere
Cloudflare serves every page.
On the whole-kitchen sheet:
- Opening the page sends our server nothing, unless this browser holds a licence: then the licence is sent to open the sheet.
- Pressing "Get the whole-kitchen sheet" asks our server for the price and PayPal's settings.
- Buying sends our server the product and then the PayPal order id. "Restore" sends the order id you type; "Check this payment" sends the order id this browser kept.
- Our server sends PayPal the product and its price, and asks PayPal whether the order was paid.
You pay inside PayPal's button; our code never asks for your card or PayPal login.
Our server has no database. It counts purchase and restore requests from each internet address per minute, to limit abuse. When a payment check fails, it writes the order id to its error log.
What is loaded from other companies
Fonts come from this site, not a font service.
PayPal's script loads from paypal.com only after you press "Get the whole-kitchen sheet". Once loaded it is PayPal's code; this site cannot speak for what it does, including any cookies it sets.
Their own pages: PayPal's privacy statement, Cloudflare's privacy policy.
Nothing else is loaded from another site.
