Privacy Policy

Data you enter in the calculators

The values you type into the calculators (amounts, percentages, dates, etc.) are processed entirely in your browser. They are not sent to any server or stored in any database. When you close the page, that data is gone.

We have no access to the numbers you enter or the results you get.

Browsing data and analytics

We use web analytics tools to understand how the site is used so we can improve it. These tools may collect information such as:

- Pages visited and time spent - Approximate country and city (derived from your IP address, which is anonymized) - Device type, browser, and operating system - Referring page (where you came from)

This data is used exclusively to improve the site experience. It is not used to personally identify you or to show you advertising.

Cookies

The site uses technical cookies necessary for its operation (such as language preference) and analytics cookies to measure site usage.

We do not use advertising cookies or cross-site tracking cookies. We do not share cookie data with third parties for advertising purposes.

Third-party services

To operate the site we use external services for:

- Web hosting and content delivery - Web analytics (measuring visits and site usage)

These providers may process technical data (such as your IP address) according to their own privacy policies. We select providers that comply with applicable data protection regulations.

Account data (future)

Currently, no account is needed to use the calculators. In the future we may offer optional features (such as saving favorites) that require registration.

If we implement user accounts, the personal data requested (such as email) will be used exclusively for the operation of those features. We will not send marketing emails without your consent.

Your rights

If you are in the European Union, the General Data Protection Regulation (GDPR) grants you the following rights:

- Right of access: know what data we hold about you. - Right of rectification: correct inaccurate data. - Right of erasure: request that we delete your data. - Right of portability: receive your data in a structured format. - Right to object: object to the processing of your data.

To exercise any of these rights, contact us through the contact page.

Children

Smart Calculators' tools are general-purpose and do not collect personal data from any user. There is no age restriction for using the calculators, as no registration is required and no identifying data is collected.

Changes to this policy

We may update this privacy policy to reflect changes in our practices or in applicable legislation. When significant changes occur, we will update the date on this page.
