Hi Product Hunt 👋 maker here.

TrueLock is an offline-first way to share a single encrypted capsule file (.cfcaps) where the access rules travel with the file — so you can send it over any channel, but it only opens when the rules match.

Rules (AND/OR):

  • time window

  • geo radius (Windows geo can be confirmed via phone relay / QR proof)

  • password (Argon2id)

  • visual key (up to 5 images, can be split across people)

  • optional device checks (when available)

Capsules can include text + attachments/media, voice messages, and an in-app photo series.

Quick question: which rule would you actually use first?
A) “send now, open later” (time)
B) “open only at this place” (geo)
C) “team unlock” (visual key)

Reply with A/B/C + 1 sentence use case — I’ll prioritize the most requested workflows.

Hey Product Hunt 👋 maker here.

A bit more detail for anyone curious:

  • TrueLock creates a self-contained .cfcaps file: encrypted payload + embedded policy (rules travel with the file).

  • Rules can be combined with AND/OR: time window, geo radius (Windows via phone relay / QR proof), password (Argon2id), visual key (up to 5 images), optional device checks.

  • Capsules can include text + attachments/media, voice messages, and an in-app photo series.

  • Current clients: Android + Windows.

If you tell me your use case, I can suggest the simplest rule setup (and I’ll use feedback to refine onboarding).
