Your data

This page explains what a session stores. It explains who can read that content, and how long Hyground keeps it.

What does a session store?

A session stores every message in it. This includes your messages and the replies of the agent. It also stores every tool call the agent ran, with its result.

Files belong to the session too. This includes the files you attach to a message. It also includes the files the agent writes while it works.

Who can read your data?

Everything in a session follows the rules for that session. See Who can see a session?.

Every user who can open the session can also open its files. Each of those users can download any file in the session. A full export carries those files too. See What does an export contain?.

What happens to your message?

Hyground sends the content of your message to the language model of your installation. The files you attach and the results of the tool calls reach the model too. The agent uses that model to write its reply.

The agent also runs tools against the systems that your administrator connected. Every tool call stays in the session. You can open it and read what the agent did.

How long does Hyground keep a session?

Your administrator can set a time after which Hyground deletes old sessions. Without that setting, a session stays until its owner deletes it. Hyground keeps a session that any user has pinned. See Pin a session.

You can delete a session you own at any time. See Delete a session.
