Days briefings fire

Real-time triggers

Urgent-keyword push

Fire an extra briefing when an inbound message contains "URGENT", "ASAP", "deadline" within a 2-hour window.

Specific-sender push

Real-time alert when Aria Chen or Paul Singh sends a message, regardless of schedule.

Quiet hours

No briefings between these times even if scheduled. Real-time alerts still come through unless silenced separately.

Model choices

Briefing composer

Used for the daily briefing synthesis — quality matters more here.

Reply processor

Used for parsing your teach replies + memory writes. Sonnet is fast + cheap; sufficient for this task.

Fall back to Sonnet on Opus overload

If Opus returns 529 (overloaded), automatically retry with Sonnet so your briefing still ships.

Settings — Privacy & Sync · End-to-end encryption + recovery

Privacy & Sync

Sync briefings + actions to your phone, end-to-end encrypted. Posthorn (the company) never sees your data — even encrypted blobs are useless to us.

Multi-device sync

End-to-end encrypted sync

When enabled, Posthorn syncs briefings + action queue (not raw email/messages) to a tiny Cloudflare relay so your iPhone can fetch them. Everything is encrypted on your Mac before leaving.

Devices linked

Add another iPhone, iPad, or second Mac. Each device gets the same view.

Recovery key

Your encryption key is backed up ✓ Safe

posthorn-recover-v1.h7k3-fz9m-q4tx-bp82-rj5w-nv1c-ye0d-uosa-mxqk-th8r

Posthorn cannot decrypt your sync without this. We never see it. Store it in 1Password or print and put it somewhere safe — losing it means re-doing all sync setup from your Mac.

Data residence

Sync region

Cloudflare datacenter region where your encrypted blob is stored. Defaults to closest to you. Encryption means region doesn't matter for privacy, but matters for latency + compliance.

Locally on this Mac

Memory database

SQLite + Mem0 store, encrypted at rest with your macOS Keychain key.

~/Library/Application Support/Posthorn

Wipe local data

Removes everything Posthorn has stored locally. Cloud-synced blob stays unless you also delete it separately.
