Privacy Policy
The short version: the tools themselves collect nothing. Analytics and advertising are the only exceptions, and both are described below.
The short version
Anything you type into a tool on this site stays in your browser. Heights, weights, salaries, passwords, WiFi credentials, dates of birth, uploaded images — none of it is sent to us, because the tools are static pages that run their calculations on your own device.
We do not have accounts, so we do not hold names, email addresses or passwords.
What is collected
Three things, none of which involve tool input.
Server logs. This site is hosted on GitHub Pages. Like any web host, GitHub records requests, which includes IP addresses and browser user-agent strings. This is standard hosting infrastructure and is governed by GitHub's privacy statement.
Advertising. We use Google AdSense to fund the site. Google and its partners may set cookies and use device identifiers to serve and measure ads, including personalised ads where you have consented. You can review and change your preferences at Google Ads Settings, and opt out of personalised advertising across participating vendors at YourAdChoices.
Local storage. Some tools remember small preferences in your browser's own storage — whether you prefer metric or imperial units, and whether you chose the light or dark theme. This never leaves your device, we cannot read it, and clearing your browser data removes it.
What is not collected
- The contents of any calculator, converter or generator field
- Files you open with the image and PDF tools — these are read by your browser and never uploaded
- Any account, contact or identity information, because there are no accounts
Cookies
We set no cookies of our own. Cookies present on this site come from Google AdSense. If you are in the EEA, UK or Switzerland, you will be asked for consent before personalised advertising cookies are set, and you can change that choice at any time.
Children
This site is not directed at children under 13 and we do not knowingly collect information from them.
Your rights
Because we hold no personal data, there is nothing for us to export or delete on request. For data held by Google as an advertising partner, use the Google links above.
Changes
If this policy changes materially, the date below will change with it and the summary at the top will reflect the new position.
