Get notified at launchHow it worksSovereign-EU infrastructure with end-to-end encryption.
Emails are encrypted before they leave your device. Even we cannot read them. Even our infrastructure provider cannot.
All email data stored exclusively in Estonia under EU privacy law. No US jurisdiction, no CLOUD Act, no foreign subpoena reach.
No tracking, no data mining, no behavioural analysis, no AI-training corpus. Your inbox is yours alone.
Your emails, your keys, your jurisdiction. Replace Gmail/Outlook without becoming the product.
Privacy and ownership as defaults — not premium tiers.
Privacy as default. Sovereignty as built-in. End-to-end encryption that you do not have to opt into.
Your supplier negotiations, your customer escalations, your legal correspondence - none of it should fund Big Tech ad models.
Same infrastructure that runs B-Storage, B-Backup, B-CRM. One vendor relationship, one jurisdiction, one bill.
