Indigenous-led software for community and research activities. The tools are built for community-based participatory research (CBPR): no participant accounts, data that stays with the research team, and results that come out ready for analysis.

mVote: sticky-note voting for groups. Participants join from a link or QR code without an account and vote on a set of items, such as candidate survey variables. Results export as a structured dataset rather than a screenshot. Live: mvote.app · Source: MalverdeSoftware/mvote

mPile: card sorting. Each participant groups cards on their own phone or computer. Responses are sealed in the participant's browser, so the site stores only data it cannot read, and deletes it when the session is closed or expires. Live: mpile.app · Source: MalverdeSoftware/mpile

Both are early releases. They share foundations in MalverdeSoftware/malverdesoftware.
