We're BACO-PAY, a volunteer association working on digital inclusion. We built something simple and a little bold: an open-source experiment that shows how the ordinary smartphones already in a neighbourhood can, together, become aware of what's happening around them — a tremor felt by many at once, the profile of a fall on a single device.

It isn't a safety product and it isn't magic. The raw data never leaves your phone; only the community's shared signal does. It's a way to explore what "looking out for each other" can mean when a small town has more phones than sensors, and to close a little of the digital gap that leaves smaller communities behind.

Running it costs almost nothing per person, but it isn't free: there are servers to keep online, code to maintain, and communities to involve. Your donation keeps the lights on and the project open — free for anyone to use, study, and improve.

When a community feels it, the network sees it. Help us keep that network running.
