Privacy Policy

At Calculora, we take your privacy seriously. This Privacy Policy explains what information we collect, how we use it, the legal basis for processing it, and the rights you have over your data when you use calculora.net ("we", "us", "our").

Information We Collect

All calculator inputs and results are processed locally in your browser and are never sent to or stored on our servers. We do not require account registration and do not collect names, addresses, or financial account details. With your consent, we collect limited technical and usage data (such as pages visited, device type, and approximate location derived from your IP address) through Google Analytics to understand which tools are useful and to improve the site.

Legal Basis for Processing

Where we process personal data based on cookies (analytics and advertising), we rely on your consent (Article 6(1)(a) GDPR), which you may withdraw at any time using the "Cookie Settings" link in the footer. Where we process data necessary for the site to function, such as your saved theme or language preference, we rely on our legitimate interest in operating the service (Article 6(1)(f) GDPR).

Cookies

We use three categories of cookies: (1) Necessary cookies, which store your theme and language preference and cannot be disabled; (2) Analytics cookies (Google Analytics), which help us understand site usage and are set only if you consent; (3) Advertising cookies (Google AdSense), used to show and measure ads and set only if you consent. You can review or change your choice at any time using the "Cookie Settings" link in the footer of every page.

Third-Party Services

We use Google Analytics and Google AdSense, both operated by Google. These services may set cookies and process data on servers located outside your country, including in the United States, under Google's own privacy policy and appropriate safeguards such as standard contractual clauses where required. You can review Google's privacy practices and manage ad personalization at Google's Ad Settings page. We do not sell your personal data to any third party.

Data Retention

Analytics data is retained by Google Analytics for up to 14 months from collection, after which it is automatically deleted. Your cookie consent choice is stored in your browser for up to 12 months, after which you will be asked again.

Your Rights

If you are located in the European Economic Area, the United Kingdom, or another jurisdiction with similar data protection laws, you have the right to: access the personal data we hold about you; request correction or deletion of your data; restrict or object to our processing of your data; request a copy of your data in a portable format; and withdraw consent at any time without affecting the lawfulness of processing carried out before withdrawal. To exercise any of these rights, contact us using the details below. You also have the right to lodge a complaint with your local data protection supervisory authority.

Children's Privacy

Calculora is not directed at children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal data from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last Updated" date at the top of this page.
