Look for humanWhat stays on the device
AI calculations run in the browser. Photos, video, frames, crops, detections and local operations are not uploaded to Look for human servers. Results, notes and history are stored in IndexedDB. Sharing or exporting is an operator decision; a chosen external app may then transmit a file under its own policies.
Preparing for offline use
With internet access, download the model and prepare the app for offline use. Check the readiness indicator and test with the network disconnected. Installing the PWA does not replace downloading the model. Phones may request permission for a large transfer. The browser or operating system can clear caches, so check readiness before each operation.
What offline mode does not provide
Registration, sign-in and retrieving current account approval require account-service access. Shared sectors, team updates and GPS reporting require internet. New map tiles may be unavailable outside cached areas. Previously working local analysis does not imply that a newly opened device without a session can sign in without connectivity.
Backing up the history
Do not clear site data before backing up results. A .lfh.zip export contains the whole local operation and images; treat it as operational material and share only with authorised people. Team positions on shared maps reach the server and are visible to approved participants in that search. Their retention is described separately in the privacy policy.
