Cross-Device Conversation Transfer with E2EE & Sharing Safety Controls

Problem: Conversations built on desktop (easy copy-paste from external sources) can't seamlessly continue on mobile where they might be more useful to user.

Requested Features:

1. Encrypted File Export/Import

• Export any conversation to a password-protected file

• Import on another device to continue the conversation natively

• Full context preserved (memory, custom prompts, files)

2. Account-Bound E2EE Sync

• Optional automatic sync across logged-in devices

• E2EE: Venice cannot decrypt; keys account-derived

• Security notice required: "Synced across devices - reduces protection against account compromise"

3. Share to Other Humans (Enhanced Safety)

• Export for sharing with explicit confirmation steps

• Optional content scrubbing (strip memory/personal context)

• Expiration controls (1hr/24hr/7day)

• Recipient verification (email or out-of-band password)

• Warning: "Recipient gains permanent access to all messages"

Security Principle: User-controlled keys for all cross-device transfers. Venice holds encrypted data only, never decryption keys.
