You don’t need to upload your workday to the cloud just to track your hours. Here is how Cenlo does things differently:
Window titles, active documents, and timesheets are uploaded to remote servers before you ever see them.
Record
01Observes open apps, browsing history and keystrokes
Upload
02Sends raw details to cloud servers
Process
03Organized and stored remotely in cloud databases
A smart model runs directly on your computer to organize your day. Raw activity stays on your device.
Classify
01Recognizes work categories locally on your device
Save
02Keeps everything in a local sqlite file on your computer
Sync (Optional)
03Sealed and encrypted with your personal key before syncing
Cenlo groups your app activity into clear projects and work sessions without sending anything to the cloud.
