Make it local.
Your lockbox stores and indexes your documents on your device, using the Entangled Halo foundation.

Before you begin
Your questions.
Answered.
What leaves my device?
Your raw documents stay in the local lockbox. The context you approve is sent to your selected AI service after masking. Always review the protected copy; your selected service’s terms and data policies apply to what you send.
Does HaloVault replace ChatGPT or another AI service?
No. HaloVault supplies private, reviewed context to supported frontier chat services, including ChatGPT, Claude, Gemini, and Grok. Your model choice remains yours.
Can my team use it with sensitive work?
HaloVault is designed around local storage, masking, and review before sending. Your organization’s policies and required approvals still determine which documents and workflows are appropriate. Talk with us about your requirements.
