Downloads

Every building block of the Ethical Saving system to download — device firmware, apps and tools. Offline-first, data-minimal and open in line with our non-profit mission. After downloading, verify the SHA256 checksums.

Note: At MVP stage this system is a comfort/alerting tool, not a medical device. It does not replace nursing or medical judgement. The bridge firmware stores no personal data locally — it runs only inside the secured facility network.
