Honest posture

Private Mode

A roadmap. Not a product. Target: 2027Q2.

Private Mode would keep a subset of fields encrypted on your device, so only you can read them. It’s aimed at entries you mark private, family-only heirlooms, and the pane you keep for yourself.
Target: 2027Q2Status: design

If we can’t keep a promise yet, it gets written here first.

Scope

What Private Mode would cover, and what it wouldn't.

In scope

  • Entry bodies marked private-only
  • Voice memos marked private-only
  • Attachment body bytes (metadata stays server-readable)

Excluded by design

  • Public profile fields (visible by design)
  • Memorial page content (moderation requires server read)
  • Shared space content (group read requires server decrypt hints)

Trade-offs

Honest downsides.

  • Lose the key and you lose the data. Before any field is opted in, there has to be a paper recovery-key ceremony a grieving person can actually follow.
  • Search stops working on private fields server-side. We’d offer a client-side index instead. It would be slower.
  • Syncing between devices needs key material you hold. That's why the design assumes at least two devices.

Why not now?

  • End-to-end encryption done badly is worse than none. Moderation and legacy transfer land first. Otherwise Private Mode quietly breaks both.
  • The recovery-key ceremony needs real user research, with grief-counsellor input, before anybody’s only copy depends on it.
  • Key rotation across a 20-year archive isn’t a solved problem anywhere. We won’t ship until there’s an answer we’d defend out loud.
