Privacy Policy

Last updated: on every build of this site.

What we collect: nothing you type

Every calculator on ecech. runs client-side. The numbers, text and files you enter stay in your browser's memory and are never uploaded to us. We operate no user database and no login system.

Local storage

We store one preference on your device — whether you chose light or dark mode. It never leaves your browser and clearing site data removes it.

Advertising

This site displays advertising served by Google AdSense. Google and its partners may set cookies or use device identifiers to serve and measure ads, including personalised ads based on your prior visits to this and other sites. You can review and adjust this at My Ad Center, and opt out of personalised advertising at aboutads.info/choices. Visitors in the EEA, UK and Switzerland are shown a consent notice before non-essential cookies are set.

Third-party requests

Pages load Tailwind CSS from a public CDN and Inter from Google Fonts. A small number of tools fetch live reference data, such as exchange rates, from public APIs; those requests contain no personal information. Hosting is provided by Cloudflare Pages, which keeps standard server logs.

Children

These tools are general-purpose utilities not directed at children under 13, and we knowingly collect no information from them.

Your rights

Because we hold no personal data about you, there is nothing for us to export, correct or delete on request. Data held by Google in connection with advertising is governed by Google's own policy, and you can exercise your choices there directly.
