Privacy policy

Last updated 29 October 2026

The short version

You do not need an account. The numbers you type into calculators stay in your browser and are not sent to us. Files you use in the PDF tools are processed on your own device and are never uploaded.

What is stored on your device

Your browser’s local storage keeps a few preferences so the site works the way you left it: your chosen country, your recently used tools and, if you use it, your calorie counter list. You can clear these at any time by clearing your browser’s site data.

Services the site connects to

To load quickly, the site uses fonts from Google Fonts and a PDF library from Cloudflare’s cdnjs. When you use the zodiac and birthday tool, your browser asks Wikipedia for events on that day of the year, which shares the day and month with Wikipedia. These services receive your IP address as part of a normal web request and handle it under their own privacy policies.

Hosting and statistics

The site is hosted on Cloudflare, which processes basic request data such as IP address and browser type to deliver and protect the site. We may use privacy-friendly visitor statistics that do not identify you.

Advertising

We may show ads, including from Google. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google’s use of advertising cookies lets it and its partners serve ads based on your visits. You can opt out of personalised advertising in Google’s Ads Settings (adssettings.google.com). Where the law requires, we will ask for your consent before using these cookies.

Affiliate links

Some links to products or services may be affiliate links. If you buy through them we may earn a commission, at no extra cost to you.

Your rights

Depending on where you live, laws such as POPIA in South Africa, the DPDP Act in India and the GDPR in Europe give you rights over your personal information. Since we do not hold accounts or calculator inputs, there is usually nothing for us to access or delete, but you can contact us with any request.
