Privacy Policy
Last updated: 13 July 2026
Overview
CalcHub respects your privacy. Our calculators run entirely in your browser — the values you enter are not transmitted to our servers.
Data we collect
- Anonymous analytics: page views and general usage statistics via privacy-respecting analytics.
- Contact form: name, email and message content — only when you voluntarily submit it.
Cookies
We use cookies for:
- Essential site functionality (theme preference).
- Advertising (see next section).
Advertising — Google AdSense
This site uses Google AdSense to display ads. Google, as a third-party vendor, uses cookies to serve ads based on your visits to this and other websites.
- Google's use of the DART cookie enables it and its partners to serve ads based on your visits.
- You may opt out of personalised advertising by visiting Google Ads Settings.
- You can learn about opting out of third-party vendors at aboutads.info/choices.
Third-party services
Some calculators (currency, crypto, live rates) fetch data from public APIs. Only the data required to display current rates is requested; no personal information is sent.
Children's privacy
CalcHub is not directed at children under 13 and does not knowingly collect data from them.
Your rights
You may request removal of any data submitted through the contact form by emailing privacy@example.com.
