Privacy Policy

Who we are

Calcora is an independent website publishing free online calculators. For any privacy question, contact hello@calcora.example.

What we do not collect

• We do not require an account, email address or any personal information to use a calculator.
• We do not transmit, store or log the values you enter into any calculator. All calculations are performed in your browser.
• We do not sell personal information.

Cookies and similar technologies

The site stores one item in your browser's local storage: your cookie choice, so we do not ask on every page. It contains no identifier.

With your consent, advertising and analytics providers may set cookies and similar technologies to measure traffic and serve ads. Until you accept, no non-essential cookie is set.

You can change your choice at any time using the Cookie settings link in the footer of every page.

Advertising

If the site displays advertising, it may use third-party vendors, including Google, that use cookies to serve ads based on your prior visits to this and other websites.

Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the internet. You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info.

Third-party vendors and ad networks may also collect information about your interaction with ads. We do not control those cookies; their use is governed by their own privacy policies.

Analytics

We may use privacy-respecting analytics to understand which calculators are used and to improve them. Analytics data is aggregated and does not identify you personally.

Analytics is only activated after you accept cookies, and stops if you later decline.

Server logs

Our hosting provider processes standard technical data — such as the page requested, the time and an approximate region — to deliver the site and protect it from abuse. These logs are retained for a short period and are not used to identify individuals.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data held about you, or to object to its processing. Because we hold no personal data about calculator users, most such requests are satisfied simply by confirming that nothing is stored.

To exercise any right, or to ask a question about this policy, contact hello@calcora.example.

Children

The site is not directed at children under 13, and we do not knowingly collect information from them.

Changes to this policy

We may update this policy as the site evolves. The date at the top of the page shows when it last changed.
