Browser-local encrypted file sharing.
I’m building SealedPacket, a local-first encrypted packet app for sensitive files and messages.
The idea is simple:
Choose text or a file
Encrypt it locally in the browser
Download a portable .sju packet
Share that packet through any channel
The server, when used, is only for account/control-plane features like identity, quotas, device approval, audit, and managed access. It is not meant to store plaintext files or recoverable packet secrets.
I built this because traditional file sharing often makes the cloud service the trusted place where plaintext lives. SealedPacket flips that: the encrypted packet is the thing you move around, and access can be controlled separately.
Would love feedback from privacy/security folks, freelancers, agencies, or anyone who has had to send sensitive files without wanting another shared-drive workflow.
