what blackbox does

A black box, not a feed

Nothing you record is public or promoted, and we don’t open your entries without your permission.

Sealed on your device

Entries are encrypted in your browser before upload. Blackbox currently holds the key so playback works across your devices; end-to-end encryption is on the roadmap.

Private by default

Never scanned for ads, never used to train models, never shown to strangers. We don’t watch your entries unless you ask us to or the law requires it.

Passed on, on your terms Coming soon

Name who inherits an entry and the moment it should reach them. Not available yet; we’re building it.
