Summary
HomeCalcHub does not require an account and does not store personal information on our servers. Calculator inputs and results are processed entirely in your browser. We do show third-party ads and use a small amount of analytics; both are explained below.
What we collect directly
Nothing personally identifying. We do not run user accounts, contact forms, payment processing, or any backend that stores your data. The calculators on this site run as client-side JavaScript — the numbers you enter never leave your device.
Third-party services
The following third parties may collect information when you visit HomeCalcHub:
- Google AdSense. Serves ads on tool pages. AdSense and its partners use cookies and similar technologies to measure ad performance and (with your consent) to show personalized ads. See Google's advertising policies for details on the data collected, the partner networks involved, and how to opt out.
- Google Analytics (when enabled). Collects anonymized usage data such as pages viewed, time on page, and approximate geographic region derived from your IP address. The IP address is anonymized before storage.
- Chatbot inference endpoint.Each calculator includes an optional AI assistant. When you send a message, the text of your message and (only if you opt in via the "Include result in question" toggle) your current calculator inputs and result are sent to our chat endpoint, which proxies the request to a language-model inference server. We do not retain conversations on our servers. The inference provider may log requests for abuse-prevention purposes for up to 30 days. Do not share personal information through the chatbot.
Cookies
AdSense uses cookies to limit ad frequency, prevent fraud, and (with your consent) tailor ads to your interests. You can opt out of personalized advertising at any time through Google's ad settings or via the consent banner on this site. We also store a small flag in your browser's local storage to remember your consent choice and recently-used calculators. No third party can read these local-storage values.
Your choices
- The consent banner that appears on your first visit lets you choose between personalized and non-personalized advertising. You can reopen it any time via the "Manage cookies" link in the footer.
- If you are in the European Economic Area, the United Kingdom, Switzerland, or California, our ads default to non-personalized until you opt in.
- You can clear all data this site stores in your browser by clearing your site data in your browser settings. This will reset your consent choice and recent-calculator list.
- You can install a tracking-protection extension or use a privacy-focused browser to block third-party cookies entirely. The calculators continue to work; you will still see ads but they will be non-personalized.
Data retention
Because we do not run a server-side database for user data, we have nothing to retain on our side. Third-party services have their own retention policies — Google AdSense's is in the link above. Calculator inputs you type stay in your browser and disappear when you close the tab unless you have explicitly chosen to remember them via your browser.
Children
This site is not directed at children under 13. We do not knowingly collect data from anyone under 13.
Changes
We will update this page if our practices change. The "Last updated" date at the top reflects the most recent revision.
