Privacy Policy

What we collect

多面手 (this site) does not currently have an account or login system. Most tools don't require you to submit any personal information.

• Amount to Chinese Numerals: runs entirely in your browser — the numbers you enter are never sent to our servers.
• Live Exchange Rates / Crypto Charts: the currency codes or coin IDs you select are forwarded through our server to third-party data providers (European Central Bank reference rates, CoinGecko) solely to fetch public market data. No personally identifiable information is included.
• Analytics: we use Vercel Web Analytics, a privacy-friendly analytics service that does not use cookies or track individual users — it only produces aggregated, anonymized page-view data.

Advertising

This site does not currently display ads. If we add an advertising service (e.g. Google AdSense) in the future, we will update this policy to describe any cookies used for ad personalization.

Third-party services

This site relies on the following third-party services to provide its features:

• Vercel (hosting and analytics)
• European Central Bank reference rates (Frankfurter API)
• CoinGecko (cryptocurrency market data)
