Privacy Policy

Summary

• Calculator inputs stay in your browser. They are never sent to a server.
• Inputs may be saved to your browser's localStorage for convenience. They never leave your device.
• Google AdSense displays ads and may track interests via its own cookies.
• Anonymous analytics (Vercel Analytics or equivalent) may count visits without identifying you.

1. Information collected

We do not require sign-up. We do not collect names, email addresses, or phone numbers.

Calculator inputs (voltages, salaries, etc.) live only in browser memory, URL query params, and localStorage. If you create a share URL, your inputs are encoded into the URL — sharing that URL shares your inputs with whoever you send it to.

Google AdSense may use cookies and identifiers for ad personalization. Their handling is governed by Google's Privacy Policy.

2. Cookies and local storage

• Local storage: per-tool input restoration. Keys are prefixed worktool:.
• Cookies (ads): AdSense personalization and frequency capping. Block via browser settings.

3. Third parties

• Vercel — hosting and CDN
• Google AdSense — ad display
• Google Fonts (optional) — typography

4. Your rights

Because we do not collect personally identifiable information, there is no central record to delete. To clear locally stored inputs, use your browser's “Clear site data” option.

5. Changes

This policy may change. The current effective date is shown at the top.
