AI Calculator Hub (“we”, “us”, “our”) operates the website and calculator tools at this domain (the “Service”). This Privacy Policy explains what information we collect, how we use it, and your choices — including how advertising partners such as Google may use cookies on our site.
1. Information we collect
- Account information — name, email address, optional phone number, and password when you register.
- Usage data — calculator inputs/results linked to your account (history, favorites, saved calculations), pages visited, and approximate usage metrics.
- Technical data — IP address, browser type, device information, referring URL, and cookie identifiers.
- Communications — messages you send through contact forms or support.
- Payment data — if you later subscribe to a paid plan, payment references are processed by payment providers; we do not store full card numbers on our servers.
2. How we use your information
- Provide, operate, secure and improve the Service.
- Authenticate accounts and prevent abuse.
- Respond to support requests and send important service notices.
- Generate AI explanations when you request them (inputs/results may be sent to configured AI providers solely to produce the explanation).
- Measure traffic and, where enabled, show relevant advertising.
3. Cookies and similar technologies
We use cookies and local storage for essential site functions (session, CSRF protection), preferences (theme, language), and — when advertising is enabled — advertising and measurement cookies. See our Cookie Policy for details and how to manage consent.
4. Advertising (Google AdSense and partners)
We may use Google AdSense and other advertising partners to display ads. Google and its partners may use cookies or similar technologies to:
- Serve ads based on your prior visits to this site or other sites.
- Measure ad performance and prevent fraud.
Google’s use of advertising cookies is described in Google’s policies, including how to control ad personalization: Google Advertising Technologies and Google Privacy Policy. You can also visit Google Ad Settings to manage personalized ads.
Where required by law (for example in the EEA/UK), we request consent before enabling non-essential advertising cookies.
5. Sharing of information
We do not sell your personal information. We may share data with:
- Service providers (hosting, email, AI APIs, payments) only as needed to run the Service.
- Advertising partners such as Google when ads are enabled, as described above.
- Legal authorities when required by law or to protect our rights, users, or the public.
6. Data retention
We retain account and saved data while your account is active. Logs and history may be kept for a limited period for security and improvement. You may delete saved items, clear history, or request account deletion from your profile settings.
7. Your rights
Depending on your location, you may have rights to access, correct, export, or delete personal data, and to withdraw cookie consent. Contact us via the Contact page. You can update profile details and delete your account from account settings.
8. Children’s privacy
The Service is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children.
9. International transfers
Your information may be processed in countries where we or our providers (including Google) operate. We take reasonable steps to protect data in accordance with this policy.
10. Changes
We may update this Privacy Policy from time to time. The “Last updated” date will change when we do. Continued use after changes means you accept the updated policy.
