Privacy is also practically not better than google, microsoft or apple unless you never send an e-mail to an adress from there. But since propably about 90% are hosted on either of them it does not really matter. Best to not use e-mails at all for any sensitive data about you.
.ch domains come with domain privacy by default. Since whois entries don’t include personal information. Also whois request are only doable through the official registry and only reveal the registrar and technical information and not personal ones.
