Privacy Policy

Effective date: September 20, 2026

The short version

We don't collect, store, or sell your personal data. Every calculator and AI tool runs entirely in your browser. Your inputs never reach our servers.

What we don't do

• We don't require accounts, email addresses, or any sign-up.
• We don't store the numbers, text, or files you enter.
• We don't use cookies for tracking.
• We don't sell user data to third parties — there is no user data to sell.

What we do use

Advertising: We display ads via a third-party ad network. The ad network may use cookies to deliver relevant ads and measure impressions. Standard industry practice; you can opt out via your ad network's privacy settings or use an ad blocker.

Aggregate analytics: We may use privacy-friendly aggregate analytics (like Cloudflare Web Analytics) that count page views without identifying individual users.

Third-party services

The Currency Converter fetches live exchange rates from the Frankfurter API (a public service backed by the European Central Bank). The query contains only the currency code (e.g. "USD"), never any personal data.

Children's privacy

CalcLabHub is not directed at children under 13. We do not knowingly collect information from children.

Changes to this policy

If we update this policy, we'll post the new version here with a revised effective date.
