Privacy Policy

Last updated: April 25, 2026

🔒 Short version: We don't collect, store, or transmit any personal data. Everything stays in your browser.

1. What Data We Collect

None. Super Crypto Exchange does not collect, store, or transmit any personal information. There are no accounts, no sign-ups, no cookies from us, and no server-side data processing.

2. Local Storage

Your browser's localStorage is used to save:

Theme preference (dark or light mode)
Watchlist — coin IDs you've starred
Portfolio — coin holdings you've manually entered
Calculator history — recent calculator results
Favorite tools and recently used tools
Beginner mode setting
Cached market data — a temporary copy of the last successful API response

All of this data lives entirely on your device. Clearing your browser's site data will permanently remove it. We cannot access or recover it.

3. Third-Party APIs

To fetch live cryptocurrency prices, Super Crypto Exchange calls these free public APIs:

CoinGecko Free API — primary data source
CoinCap API — fallback source
Binance Public API — price fallback

Your browser makes these requests directly. Your IP address may be visible to these APIs under their respective privacy policies. We do not proxy these requests or log them.

4. Google Fonts

The site loads fonts from Google Fonts. Google may log font requests under their privacy policy. No personal data is passed in these requests beyond standard HTTP headers (IP address, referrer).

5. No Advertising, No Tracking

There are no advertising networks, no analytics scripts (no Google Analytics, no Facebook Pixel, no similar tools), and no user tracking of any kind on this site.

6. Calculator Inputs

Numbers you type into calculators are used only to compute results in your browser. They are not transmitted anywhere. A summary of recent calculations may be saved to localStorage for your convenience.

7. Your Rights

Because we don't collect personal data, there is nothing to request, correct, or delete on our end. To remove all local data, simply clear your browser's site data for this domain.

8. Changes to This Policy

If we make meaningful changes to this privacy policy, we will update the "Last updated" date above. Continued use of the site constitutes acceptance of the updated policy.
