# Systems and Access

> What Ari is connected to, what he can see and do in each system, and how to manage that access.

You decide what Ari can reach. This page answers what each connection lets him see and
do, and how to manage access over time. To connect a new system, see
[Connecting a System](/ari/guides/connecting-a-system).

<AccordionGroup>
  <Accordion title="Which systems can Ari connect to, and what can he do in each?">
    Ari queries your systems live at request time. He doesn't cache data or rely on periodic
    syncs, so answers reflect what's true right now.

    Live queries are the trade-off for accuracy: first answers typically take a few seconds
    while Ari fetches current data. If an invoice was paid five minutes ago, he knows.

  </Accordion>

  <Accordion title="Are writes always approval-gated, even for systems where Ari has write access?">
    Yes. Connecting a system grants Ari read and write access, but every write still passes
    through [your approval](/ari/guides/approvals), regardless of which system it touches.
  </Accordion>

  <Accordion title="How is contract access scoped?">
    Contract documents are stored encrypted, and team members can only view contracts for
    customers they have access to.
  </Accordion>

  <Accordion title="Does Ari ever see raw payment data?">
    No. Payment data stays in Stripe: Ari never sees raw card numbers, and payment methods
    are tokenized in line with PCI requirements.
  </Accordion>

  <Accordion title="Who can approve Ari's actions?">
    Team members with finance or admin permissions can approve actions. This is configured
    in your workspace settings.
  </Accordion>

  <Accordion title="How do I manage or remove a system's access?">
    Access is managed in the **Integrations** page of the LedgerUp control panel: reconnect
    an expired authorization, switch accounts, or disconnect a system entirely. Disconnecting
    removes Ari's ability to read or act in that system immediately.

    If Ari can't answer a question you expect him to handle, check here first: the relevant
    integration may not be connected, or its authorization may have expired. See
    [Troubleshooting](/ari/answers/troubleshooting).
