The short version
We don’t collect personal information. There are no cookies, analytics, ads, trackers or accounts on this site.
Your calculations
Tables are worked out entirely in your browser; the numbers you type aren’t sent to us. The page address updates with your number and range (for example ?number=17&from=1&to=20) so you can bookmark or share a table. That address only reaches our host if you open or share the link, like any other web address.
Stored in your browser
If you switch between the light and dark theme, your choice is saved in your browser’s local storage under ttc.theme. It never leaves your device, and clearing your browser’s site data removes it.
Hosting
The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical request data, such as IP addresses, to deliver the site and protect it from abuse. SeeCloudflare’s privacy policy.
Changes
If this policy changes, we’ll update this page and the date at the top.
