Security metadata and abuse prevention
The channel is designed to minimise identifying data. To protect it against flooding and misuse, the network address of a web submission is processed briefly and turned into a one-way code that changes every day. That code is kept in short-lived counters (deleted within 48 hours) and is never stored with the report. Unusual timing or volume is flagged for human review as a “submission pattern anomaly”; reports are not discarded or treated as untrue because of it, since many workers may share the same site Wi-Fi. Workers are not fingerprinted or tracked across visits.
Receipt codes and status updates
After sending, a worker can receive a random receipt code created on their own device. Libera stores only a one-way hash of it. The code shows a short, fixed status for the grouped concern — received, under review, action taken or closed — and never details, counts, identities or other people’s reports. Not every investigation can be fully disclosed while it is ongoing.
Reporting for someone else
Workers can report a concern affecting themselves, another worker or a group. Share only what is needed, avoid names and personal details of others, and never put yourself in danger to gather evidence.
Photos, video, audio and documents
Uploaded files can contain faces, voices, name badges, locations or other identifying details. On the web form, image location and camera metadata are removed before upload, but the picture itself is unchanged. Unsent answers are kept only in the open browser tab and uploaded media is not stored on the device. Sending requires a connection; there is no offline submission.
