Who runs this site
DoIt Calculators is an independent, one-person project based in Sweden. You can reach us at alexandraalin8182@gmail.com — see the About & Contact page for more.
What information we collect
The calculators on this site run entirely in your browser. Numbers you type into a calculator are never sent to our servers, stored in a database, or shared with anyone — they exist only on your device while the page is open.
Like most websites, we may still collect limited technical information automatically, such as:
- Pages visited and time spent on the site, via analytics tools such as Google Analytics (if enabled)
- General device and browser information (type, screen size, approximate location from IP address)
- Cookies set by advertising partners, described below
Cookies and advertising
This site may show ads served by Google AdSense. Google and its partners use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google's Ads Settings, or by visiting www.aboutads.info for more choices.
When you first visit, a banner asks whether you accept or reject cookies used for advertising. Rejecting is as easy as accepting, and the calculators work the same either way. Nothing used for advertising is loaded until you accept. Your choice is stored in your browser (local storage) so you are not asked on every page, and you can change or withdraw it at any time with the "Cookie settings" link in the footer of every page.
Visitors in the EEA, the UK and Switzerland are asked for consent before advertising cookies or similar technologies are used. Once advertising is switched on, this is done through a consent management platform (CMP) certified by Google, and if you decline you may still see ads that are not personalised, where this is permitted.
Third-party services
We may use the following categories of third-party service, each with its own privacy policy:
- Advertising: Google AdSense
- Analytics: The site does not currently use an analytics tool. If that changes, this policy will be updated.
- Hosting: The site is delivered by a third-party web hosting provider, which may process technical data such as IP addresses in server logs.
Your rights (EU/UK visitors — GDPR)
If you're located in the EU or UK, you have the right to request access to, correction of, or deletion of any personal data we hold about you, and the right to object to or restrict certain processing. Since this site does not require an account and does not store your calculator inputs, we typically hold very little personal data beyond basic analytics and advertising cookies. To make a request, contact us at alexandraalin8182@gmail.com.
Children's privacy
This site is not directed at children under 13 (or the relevant age in your jurisdiction), and we do not knowingly collect personal information from children.
Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with an updated date at the top.
