Automated tracking and timeline classification running strictly on your device. Zero cloud logs, zero activity telemetry, and zero subscription traps.
We are finalizing local classification benchmarks and cross-platform envelope sync. Early waitlist members receive early offline builds first.
Automatic timesheets without the surveillance machinery. Compare the two execution models:
Window titles, URLs, and keystroke metrics are transmitted to a SaaS backend before you can review them.
Capture
01Apps, browser URLs, screenshots
Dispatch
02Raw logs transmitted to SaaS servers
Index
03Indexed remotely in cloud databases
Local embedded ML classifies activity into a timeline on-device. Only zero-knowledge blobs leave for sync.
Classify
01Local embedded ML, zero raw upload
Store
02Timeline stored in local SQLite database
Sync
03Zero-knowledge end-to-end encrypted
Cenlo categorizes app context and time into a tidy ledger without sending logs outside.
Under the hood
A compact on-device model matches context to custom tags without remote API latency.
Timeline records and encryption keys are sealed with unique keys before leaving your machine.
Under the hood
AES-256-GCM Zero-Knowledge Dual Envelope encryption. Cenlo relays only see sealed ciphertext.
Pair trusted machines instantly with a single offline cryptographic handshake.
Under the hood
Ephemeral key agreement occurs directly device-to-device. No shared cloud master key exists.
Bill accurately without a surveillance layer watching every keystroke.
Track billable hours where confidentiality is non-negotiable.
Build a shared culture of transparency without invasive keystroke and webcam surveillance.
Fleet-wide time insight with a privacy posture your legal team will sign.
See your own rhythm, privately, across every device you own.
Switch seamlessly between laptop and mobile. The cryptographic ledger syncs instantaneously.
Cenlo uses a zero-knowledge, dual-envelope scheme. Devices exchange sealed payloads that the sync relay cannot open. Only linked endpoints hold decryption keys.
Two discrete encryption layers safeguard timeline payloads before they leave device memory.
Pair secondary computers and phones securely using one-time visual key exchanges.
BIP-39 compliant deterministic backup phrases created on your machine. Never transmitted.
Hardware-backed biometric passkeys unlock sync nodes without centralized password vaults.
