01.A

Local-First SQLite Persistence

Every note, timestamp, and attachment writes directly to an on-device SQLite database in Write-Ahead Logging mode. The app launches cold in under 120 milliseconds and works identically in a subway tunnel or at 35,000 feet.

STORAGE ENGINE SQLite 3 + FTS5
Plaintext Markdown Export

01.B

Zero-Knowledge Encrypted Relay

For subscribers who work across phone and tablet, payloads are encrypted client-side using XChaCha20-Poly1305 before leaving the device. Ternframe servers relay opaque ciphertext and hold no decryption keys.

CRYPTOGRAPHY Client-Side Keyring
Zero Plaintext Telemetry

01.C

No Ad Networks or Behavioural Trackers

Our binaries ship with zero third-party advertising SDKs, zero cross-app fingerprinting, and predictable customer-funded licensing. Your workspace remains private property, not training fodder.
