Patient notes deserve
military-grade encryption.
Medical notes contain the most sensitive personal information imaginable. Yet doctors routinely use cloud-based tools that store patient observations on remote servers. Writtt keeps your medical notes encrypted on your device with AES-256 — no server, no sync, no breach surface.

Cloud-stored medical records
Patient observations on cloud note apps sit on servers managed by tech companies — creating breach exposure and regulatory risks you didn't sign up for.
Third-party access risks
Cloud providers can access stored data for maintenance, legal compliance, or AI training. Your patient's diagnosis shouldn't be a data point.
Regulatory exposure
Using non-compliant tools for patient-related notes creates regulatory risk. Data breaches in healthcare carry some of the highest penalties across industries.
Security that matches the sensitivity.
AES-256 per-document encryption
Each medical note is individually encrypted with AES-256-GCM. Keys are derived from your password via PBKDF2 and never leave your device.
Zero cloud dependency
All data stays on your local machine. No sync service, no cloud backup, no remote storage. There is literally nothing for a server breach to expose.
Works offline in any environment
Hospital networks can be unreliable. Writtt works perfectly without internet — write notes between rounds without connectivity concerns.
No data collection whatsoever
Zero telemetry, zero analytics, zero metadata tracking. Writtt cannot report what you write because it has no mechanism to do so.
“A patient's medical record is not a data point. It's a human story that deserves the same confidentiality as the exam room.
Frequently asked questions
Writtt provides AES-256 encrypted local storage ideal for personal clinical notes. It is not an EHR replacement but excels as a secure companion for observations, case reflections, and research notes that should never touch a cloud server.
Writtt's architecture — local-only storage, AES-256 encryption, zero data transmission — inherently minimizes regulatory risk. However, specific compliance requires organizational policies and controls beyond any single tool. Consult your compliance team.
Encrypted vault files are protected by AES-256-GCM encryption. Without your password, the data is cryptographically unrecoverable. Combined with device-level encryption (FileVault/BitLocker), a lost device does not mean lost confidentiality.
