Last updated: 23 August 2026. This template is a starting point — have it reviewed for your jurisdiction before you launch, and update it the day you enable advertising.
Who we are
CalcHub is operated by Adiram. For any question about this policy or your data, write to customersupport@adiram.net.
The short version
Values you type into a calculator stay in your browser. They are never transmitted to us or stored on any server. We do collect anonymous usage statistics, and once advertising is enabled, our advertising partners may set cookies.
Information we collect
- Calculator inputs: none. All maths runs client-side in JavaScript.
- Analytics: we use Google Analytics to record pages viewed, approximate country, device type, and referring site. This data is aggregated and does not identify you personally.
- Server logs: our host records standard request logs, including IP address, for security and abuse prevention.
- Contact email: if you email us, we keep that correspondence to answer you.
Cookies and advertising
We use cookies for analytics and, where enabled, for advertising. Third-party vendors including Google use cookies to serve ads based on your prior visits to this and other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendor cookies at aboutads.info/choices.
Visitors in the EEA, UK and Switzerland
Where required, we ask for your consent before setting non-essential cookies, using a Google-certified consent management platform. You can change or withdraw your consent at any time from the cookie settings link in the footer. Our legal basis for analytics and advertising cookies is your consent; for security logging it is our legitimate interest in protecting the service.
Your rights
Depending on where you live, you may have the right to access, correct, delete, or restrict processing of your personal data, and to object to processing or request portability. To exercise any of these, email us at customersupport@adiram.net. Residents of California may also request disclosure of categories of personal information collected; we do not sell personal information as that term is defined by the CCPA.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.
Changes
We will update this page when our practices change, and revise the date at the top.
