HEARTware
A private relationship dashboard for one household. Eight years of communication, music, photos, and shared life, collapsed into the screens that two specific people open every morning.
What it is
HEARTware aggregates communication history, listening data, calendar events, photos, and ritual data for two consenting partners and presents it back to them as charts, timelines, written reflections, and an evolving set of small rituals built for couples. Both partners share equal access. Both contribute equally to its content. The dashboard's only audience is the two people whose lives it documents.
Who uses it
Access is restricted to a fixed allowlist of email addresses configured at the application layer. Any account outside that allowlist that tries to authenticate is rejected at the server, the client, the database security rules, and the storage rules — defense in depth, four independent layers. There is no public sign-up. There is no waitlist. HEARTware is not a product you can buy.
