Privacy Policy

What we collect

You can browse the public CalCalc website without creating an account. We do not currently ask for a name, password, or payment details to use the site.

When you open a page, our servers and infrastructure providers necessarily receive technical request data such as IP address, browser and device metadata, requested URL, referrer, and language preferences exposed by your browser headers. We use that information to deliver pages, cache content, diagnose failures, and protect the service.

If you email us, we receive your email address, your message, and any details you choose to include so we can reply and handle the request.

Core calorie calculations on the public site run in the browser. We do not need to send your age, height, weight, activity level, or goal selections to our servers just to show a result.

Analytics

In production, we use Yandex Metrika only after you accept analytics cookies through the site banner. It can receive page URLs, referrers, browser and device details, link clicks, scrolling behavior, and session-replay style diagnostics through Webvisor.

We use that data to understand where pages break, where navigation causes friction, and which parts of the site need attention. We do not use calculator inputs to build advertising profiles, and we do not sell personal data.

How we use data

We use data for a small number of practical reasons. The point is to run the site cleanly, not to collect information for its own sake.

• Deliver pages, localize the site, and remember language and country preferences.
• Measure traffic and understand which paths, pages, or interactions need work.
• Monitor security, detect abuse, and debug operational problems.
• Reply to emails, privacy requests, and follow-up questions you send us.

When we share data

We share data only when it is necessary to run the site or when the law requires it. That can include hosting and infrastructure providers, plus Yandex as our analytics provider on production pages.

We may also disclose information if we need to protect the service, enforce our rights, investigate abuse, or comply with a valid legal obligation. We do not sell your personal data.

How long we keep it

Preference cookies expire automatically after their stated lifetime. Email correspondence is kept only as long as it helps us resolve the conversation and any reasonable follow-up.

Operational logs and analytics are kept for security, diagnostics, and reporting rather than permanent storage. Where retention is controlled by a service provider, that provider's settings also apply.

Your choices and rights

You can choose analytics cookies or only necessary cookies from the site banner, and you can also block or delete cookies in your browser at any time. If you do, the site may stop remembering your preferred language or country view.

If you want to ask what personal data we hold about you, correct something, or request deletion where applicable, email privacy@cal-calc.com. If you write from the same email address used in the original conversation, that makes verification much easier.

Children

CalCalc is a general-audience website. It is not intended for children to send us personal information directly. If you believe a child has contacted us with personal data, email privacy@cal-calc.com and we will review it.

Changes to this page

If our data handling changes in a material way, we will update this page before the new handling goes live and change the date at the top of the policy.
