Your knowledge stays yours.

Kazn’s hosted service runs on Amazon Web Services in Montréal (the ca-central-1 region). Your workspace’s database, search index and files stay in that region.

• Kazn is built from one server program and a standard Postgres database, with no services that only one cloud offers, so it can move if it ever needs to.
• Version 1 runs on Quactor’s cloud only. Running Kazn on your own servers comes later.

Every project, page, agent and activity record belongs to exactly one workspace, and the database itself refuses any record that points into another workspace.

• Automated tests check that two accounts can’t reach each other’s data by any route.
• Search checks permissions on every result before it is returned, including search by meaning.
• Deleting your account removes your sign-ins and your workspaces with all their history.

An AI agent never changes your knowledge directly. What it wants to add or change arrives in your Inbox as a proposal, beside the current version, with the agent’s reason. Nothing changes until you approve it.

• An agent can’t change an approved decision on its own.
• Each agent has its own key, and Kazn stores only a hash of it.
• You give each agent access per project, read or propose, and can pause or revoke it at any time.
• Every agent tool call, including what it read, is recorded in Activity.
• If an agent proposes a change to something that has changed since, the proposal is marked out of date and can’t be approved.

Kazn has a built-in assistant that answers from your workspace. It is off in every workspace until the owner turns it on, after being shown where workspace text goes.

• The assistant uses the AI provider the workspace owner connects, such as Anthropic or OpenAI, with their own key. Your workspace stays stored in Canada; text sent to the assistant is processed by that provider, under its terms.
• It prepares changes but never makes them. A prepared change is applied only when you approve it, once, within 30 minutes.
• The workspace owner chooses how long chats are kept: until deleted, 30 days, 90 days or one year.
• It warns you when a page contains instructions that look planted to steer an AI.
• Each workspace has a daily question limit, so nothing runs away.

Kazn keeps every version. Replaced decisions stay linked to what replaced them, and edits are checked so nothing is silently overwritten.

• Every piece of information shows where it came from.
• Customer-owned data is one of our quality rules: ask us and we send you a copy of everything. Export from inside Kazn comes later.
• Credentials for the tools you connect are encrypted and never shown again after you save them.
