Service Providers

Last updated: November 2026

Companies that work for us

Only the optional Mailzo account uses our servers. These companies help us run it. They work under contract and may use the information only to provide their service to us.

ProviderWhat they do for usWhat they handle
EmailitSends sign-in codes and account emailsYour email address and the email we send
HetznerRuns our account and update servers in GermanyYour account email, device names, and your encrypted vault and team data, which we can't open

Your email is never sent to any of them. We'll update this page before adding a new provider that handles your personal information.

Services the app connects to for you

These aren't our providers. The app connects to them directly from your Mac, only when needed:

  • Your email and calendar providers
  • Mozilla's email settings directory (autoconfig.thunderbird.net): only the domain of your address
  • Gravatar: a scrambled version of a sender's address, to show their picture
  • DuckDuckGo icons: a company's domain, to show its logo
  • The AI company you choose, if you turn AI on
