The Technical Reality: Why Native Apps Fail When Powered Off
Meta's WhatsApp Business 'Away Message' requires your physical phone to maintain an active internet connection to detect messages. Android third-party apps read system notifications, failing instantly if battery dies and completely blocked on iPhone. Outpost utilizes official Multi-Device companion protocols, executing rules in cloud memory independently of your phone's battery state.

Frequently Asked Questions
Everything you need to know about off-grid auto-replies and security.
Will my WhatsApp account get banned for using Outpost?
No. Outpost connects as a legitimate Multi-Device companion session (identical to WhatsApp Desktop or Web). It strictly enforces human rate limits (1 reply per contact every 4 hours by default) and never sends unsolicited bulk blasts.
Does Outpost store my private WhatsApp messages?
Never. Outpost operates with an ephemeral in-memory processing engine. Inbound messages are evaluated in volatile RAM to check sender cooldowns, send automated replies, and are immediately dropped. No message bodies are ever written to disk.
Does this require WhatsApp Business?
No. Outpost functions seamlessly with both personal WhatsApp accounts and WhatsApp Business accounts via companion multi-device pairing.
