<AccordionGroup>
  <Accordion title="Does Quarkle train on my writing?">
    No. And we ensure our AI providers cannot train on your data either.
  </Accordion>

  <Accordion title="Will Quarkle ever sell my data?">
    No. We'd rather earn money with a better product.
  </Accordion>

  <Accordion title="Is my writing private?">
    Yes. Your manuscripts are private to you unless you explicitly share them or turn on a public reading link.
  </Accordion>

  <Accordion title="What files can I import and export?">
    Import: **PDF**, **Markdown**, and **plain text**. Export: **PDF**, **Word**, **Markdown**, or **plain text**. See [import & export](/getting-started/import-and-export).
  </Accordion>

  <Accordion title="What's the difference between Basic and Pro?">
    **Basic** is free, with unlimited Chat and critique and a solid default model. **Pro** adds model selection, the full Story Atlas, custom reviewers, Open Expression, and a far larger daily allowance. Full breakdown in [plans & pricing](/account/plans).
  </Accordion>

  <Accordion title="How do I cancel my subscription?">
    Open your **avatar → Manage Subscription** to reach your billing portal, and cancel anytime. See [manage your account](/account/manage-your-account).
  </Accordion>

  <Accordion title="How do I delete my account?">
    Open your **avatar → Settings → Danger → Delete Account**, then type `delete my account`. It's immediate and permanent. See [manage your account](/account/manage-your-account).
  </Accordion>

  <Accordion title="When do you add the latest AI models?">
    We add new models quickly after release. Pro users can request specific models. Reach us at **[team@quarkle.ai](mailto:team@quarkle.ai)**. See [models & providers](/under-the-hood/models-and-providers).
  </Accordion>

  <Accordion title="Is Quarkle trying to replace human creativity?">
    The opposite. Quarkle is deliberately built to minimise AI writing and maximise AI critique, so the story stays yours. Read [our mission](/about/mission).
