Privacy & cookies
Last updated: 2026-10-05
Calctera is designed so calculations run in your browser. This notice explains what is and is not sent when you use the site.
Your calculations
Calculator inputs and results are processed in your browser. Calctera does not intentionally send those values to Google Analytics. Shareable calculation state may be stored in the URL fragment; URL fragments are not sent to the web server in normal HTTP requests.
Google Analytics
If you accept analytics, Calctera loads Google Analytics 4 to measure page views and generic interactions such as calculator use, reset, language changes and related-calculator clicks. Event data contains identifiers such as calculator, category and language, not the numbers or text you enter.
Cookies and local storage
Analytics cookies are used only after you accept analytics. Your consent choice and language preference may be stored locally in your browser because they are necessary for the requested site behavior. Rejecting analytics removes known first-party Google Analytics cookies where possible.
Hosting and security logs
The hosting infrastructure may process standard request information such as IP address, time, requested path, browser information and HTTP status for delivery, reliability and security.
Google and third parties
When analytics is enabled, Google processes Analytics data under its own terms and privacy documentation. Advertising storage, advertising user data and ad personalization remain disabled by Calctera.
Your choice
You can reject analytics and continue using the calculators. You can change your choice at any time using Cookie settings in the footer.
