Privacy

Effective 25 October 2026.

NEXUS TRACE is a private assistant run for one person, its owner.

What it stores

It stores what the owner files and, once connected, the owner's mail, calendar events, files dropped in its Drive folder, and contacts taken from message headers. All of it is kept on its own server, with encrypted nightly backups.

It also keeps a model of the owner (About you), built only from the owner's own questions and choices, never from their mail or documents, in a memory service (Honcho) on the same server. The owner can confirm, correct or forget anything in it.

Who can see it

Only the owner can sign in.

Google data

Google data is read-only and used only to show the owner their own information inside NEXUS TRACE. It is never sold, shared, or used for advertising, and NEXUS TRACE does not use it to develop or train AI models.

Use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

AI providers

Text from items whose topics allow AI is sent to the AI providers the owner has configured (currently Anthropic (Claude), with xAI (Grok) as the fallback; audio goes to xAI only (Grok Voice Transcribe); handwriting the owner sends from the Board goes to Anthropic (Claude) only; pictures with no words in them go to Anthropic (Claude) only, once the owner turns on Read my pictures) only to sort and summarize it for the owner.

Handwriting on the Board is sent, before any rule sees it, only when the owner has turned that on and taps Read; NEXUS TRACE does not keep the drawing.

A picture with no words in it is sent, shrunk and with its location removed, to be described only when the owner has turned on Read my pictures and no rule that keeps the AI out matches its name, folder or caption.

The person model's own AI calls go through NEXUS TRACE to Claude and count against the owner's daily AI cap; it finds related memories with a small model that runs on the server itself.

Once a week NEXUS TRACE reads the public news sources the owner lists and asks Grok to read the public X accounts on that list; nothing of the owner's is sent with those requests.

Your choices

The owner can disconnect Google at any time and delete what they filed. Questions go to the support contact on the Google sign-in screen.
