Privacy Policy

1. Overview

This policy explains what data is processed when you use Calcrete at https://calcrete.app and why. The site is designed to collect only what is needed to operate the calculators, remember preferences, and understand service quality.

2. Data processed by the site

The calculators require no account and do not ask for your name, phone number, address, payment details, or identity documents. Measurements and calculation inputs are processed in your browser. They may appear in the URL query string so that you can share a calculation.

Your browser stores theme, accent colour, currency, and unit preferences locally. These settings are not an account and remain on your device until you clear the site's data.

3. Web analytics

When a counter is configured, the site uses Yandex Metrica for aggregated visit statistics, traffic sources, device information, and page interactions. Metrica may use cookies and process technical information such as IP address, browser data, and visit time. Session replay (Webvisor) is disabled.

Yandex processing is governed by the Yandex Privacy Policy and Metrica Terms of Use. You can restrict cookies and analytics scripts through your browser or content-blocking extensions.

4. Purposes and retention

Technical and analytics data is used to keep the site reliable, diagnose errors, measure which calculators are useful, and improve the interface. Local preferences remain until you remove them. Metrica retention is governed by the counter settings and Yandex rules.

5. Sharing and security

The site does not sell user data. Technical data may be shared with infrastructure providers and Yandex as needed for hosting and analytics. Reasonable security measures are used, but internet transmission cannot be guaranteed to be completely secure.

6. Your choices and contact

You may clear local data in your browser, block cookies, and request information about or deletion of data available to the site operator. Contact: privacy@calcrete.app.

7. Changes

This policy may change when site features or legal requirements change. The current version and its update date will always be published on this page.
