Privacy Policy
What data this site does and does not collect, and what your choices are.
Last updated: 2026-09-23
The short version
The values you type into a calculator stay in your browser. They are never transmitted to us or to anyone else. We do not ask for your name, your email or any account.
Who is responsible
The controller of this website is Rita Raquel Carvalho Rodrigues de Oliveira, 3080-325 Figueira da Foz, Portugal. For any question about this policy, write to hello@paritian.com.
What your browser stores
To make the site usable we store a few small items in your browser (in local storage, not in cookies sent to a server): your chosen language, your chosen theme, your cookie consent choice and any tools you mark as favourites. You can delete all of it by clearing site data in your browser.
Measurement
With your consent we count page views and which tools are used, in aggregate, so we know which tools deserve improvement. We do not build profiles and we do not try to identify individual visitors. You can refuse this in the cookie banner or in the cookie settings, at any time.
Measurement on this site is done with Google Analytics 4, provided by Google Ireland Limited. It sets its own cookies in your browser and may process the data outside the European Economic Area. It is configured without advertising signals and without ad personalisation, your IP address is used only to derive the country and is not kept in the reports, and none of it is loaded until you accept measurement in the cookie notice. How Google handles data from sites that use its services is described at https://policies.google.com/technologies/partner-sites.
Advertising
This site is funded by advertising. With your consent, advertising partners may set cookies or read device identifiers to select and measure ads. Where required, you can refuse this and still use every tool on the site with no restriction.
The advertising partner used on this site is Google, through the AdSense programme. Google and its partners use cookies to serve ads based on your previous visits to this site or to other sites, and may combine that with information they already hold.
You can turn off personalised advertising from Google at any time at https://adssettings.google.com, and opt out of personalisation by many other vendors at https://optout.aboutads.info. How Google handles data from sites that use its services is described at https://policies.google.com/technologies/partner-sites.
Advertising partners are independent controllers for the data they collect. Their own privacy notices describe what they do with it.
Hosting and logs
The site is served as static files by a hosting provider, which keeps short-lived technical logs (such as IP address and requested page) for security and abuse prevention. This is the provider's own processing, necessary to deliver a website at all.
Your rights
Depending on where you live, you may have the right to access, correct, delete or object to the processing of your personal data, and to lodge a complaint with your supervisory authority. Because we do not hold accounts or contact details, in most cases there is simply nothing held about you. Write to hello@paritian.com with any request.
Children
This site is not directed at children and does not knowingly collect data from them.
Changes
If this policy changes in a way that affects you, the updated version will be published on this page with a new date.
