Frequently asked questions

What does Tuta do?

Tuta is end-to-end encrypted email and calendar — a german privacy-first alternative to gmail. It is listed under email, privacy, and security on EU Alts because its core functionality serves teams looking for a European email tool with EU data residency, typically as a switch away from Gmail.

Is Tuta GDPR compliant?

Tuta is headquartered in Hannover, Germany and falls under EU jurisdiction, so it likely processes user data under the GDPR by default. Customer data processing is supervised by Germany's data protection authority, the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI). EU Alts has not independently verified Tuta's exposure to the US CLOUD Act, so we can't confirm it either way.

How do teams switch from Gmail to Tuta?

Teams considering a move from Gmail to Tuta are usually drawn by its email workflow fit. EU Alts has not independently verified Tuta's exposure to the US CLOUD Act, so treat any CLOUD Act or Schrems II conclusions as provisional. Plan a migration in stages regardless: export your data from the US incumbent, pilot Tuta with a small team, then move the rest once integration coverage is confirmed.
