Frequently Asked Questions
Does this violate GDPR or privacy laws?
Because all parsing happens 100% client-side in your own browser with no server storage, you maintain complete data sovereignty and GDPR compliance.
Can it handle obfuscated emails like name [at] domain.com?
Standard RFC email addresses are parsed. For non-standard strings, replace [at] with @ before extraction.
