Your Sessions. Your Records. Your Keys.

The Most Protected Records

Why Privacy Matters

Psychotherapy notes are the most protected class of medical information under HIPAA. But even routine billing records reveal sensitive details:

• Client names reveal who is seeking mental health care
• Session frequency reveals treatment intensity
• Billing codes may indicate diagnosis categories
• Appointment times create patterns that could be exploited

Zero-Knowledge Architecture

How E2EE Protects Your Practice

1. Keys generated on your device — Your encryption keys never leave your iPhone, iPad, or Mac
2. Data encrypted before sync — Client names, session notes, and billing details are encrypted locally
3. Your iCloud, not ours — Data syncs to your personal iCloud via CloudKit. We never see or store it — not even encrypted
4. 12-word recovery phrase — You control the only way to decrypt your records

Built for How You Work

The Tenths Method

Mental health billing often uses 15-minute increments, but many insurers and private-pay practices bill in tenths (6-minute units). Tenths converts automatically:

• One-Tap Timer Start — Per client tracking
• Flexible Billing — Different rates for individual, couples, group
• Archive Inactive Clients — They're still encrypted
• Cross-Device Sync — iPhone, iPad, Mac — all encrypted

A Note on Compliance

HIPAA Considerations

Tenths is designed with privacy-first architecture that supports HIPAA compliance goals, but we are not a covered entity and do not sign BAAs.

Why this matters:

• Data encrypted at rest and in transit
• Zero-knowledge architecture means we have no access to your data
• No BAA required because we never access your protected information
• Your data stays in your iCloud account, encrypted

Recommendation: Consult with your compliance advisor about your specific practice requirements.
