If you intend to email me sensitive data, I recommend you consider setting up a Protonmail email account (free via https://protonmail.com), which will keep your information securely encrypted and only accessible between ourselves (my email – but not the contact form via this site – runs through this system, however you can still email me from any email system but non-Protonmail accounts will not be encrypted).
