Which hash algorithm should I use?

SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered weak for security but still useful for checksums and non-security applications.

Is my input sent to a server?

No. All hashing is done locally in your browser using the Web Crypto API (and a JS implementation for MD5).
