🔓 Open Source
Open source tools let you verify the code does what it claims. Look for tools with published source code and active community review.
🔒 End-to-End Encryption
E2E encryption means only you and your intended recipients can read your data. The service provider cannot access your content.
🌍 Jurisdiction
Where a company is based affects what laws they must follow. Swiss and EU-based services often have stronger privacy protections.
✓ Audited
Third-party security audits provide independent verification. Look for services that publish their audit results.
