Nothing leaves your browser. The calculators, converters, text tools, password generator and developer utilities all compute locally in JavaScript. The numbers and text you enter are not sent to any server, not stored, and not visible to anyone operating this site.
Two tools are necessarily different:
No analytics or advertising cookies are set until you accept them. Until you make a choice, Google Analytics is loaded with consent signals set to denied, which means it sets no cookies and stores no identifiers. If you accept, Google Analytics 4 records aggregate usage - which pages are visited, roughly where visitors come from, which device types are used - with IP anonymisation enabled.
If you decline, none of that runs, no advertising is shown, and every tool continues to work exactly as before. Your choice is stored in your browser's local storage, not in a cookie, and is never sent anywhere.
This site carries Google AdSense advertising, loaded only after you accept advertising cookies. Google may use cookies to serve ads based on your prior visits to this and other sites. You can review and adjust that at Google My Ad Center , and opt out of personalised advertising from participating vendors at aboutads.info/choices .
The site stores one item locally: your cookie choice. It stays in your browser and is readable only by this site. Clearing your browser data removes it and the banner will ask again.
Under the GDPR you may request access to, correction of, or deletion of personal data held about you, and you may object to processing or withdraw consent at any time. Because this site holds no accounts and no user records, in practice there is very little to request - the analytics data is aggregated and not linked to an identity. Withdrawing consent is done with the button below.
Your cookie choice is shown here, and can be changed at any time, once the page loads.
