## General

<AccordionGroup>
  <Accordion title="Do I need to know how to code?">
    Not at all. Paperline is an AI iOS app builder for people who want to ship real apps without learning to code. Just describe your idea in the chat — Paperline takes care of the structure, logic, UI, and deployment.
  </Accordion>

  <Accordion title="Is this a real app or just a prototype?">
    Real, production-ready apps. You'll build native iOS apps with AI that you can submit to the App Store. Submission
    requires a developer account and passing App Store review.
  </Accordion>

  <Accordion title="Can I make changes after it's built?">
    Absolutely. Keep the conversation going to add features, refine the design, or fix bugs — all via natural language, any time.

## Security & Privacy

<AccordionGroup>
  <Accordion title="Is my data secure?">
    Yes, your data is secure. Your project is stored locally on your computer. When Paperline syncs or builds, only the necessary data is sent to our servers over encrypted connections. We don't keep a full copy of your project in the cloud.
  </Accordion>

  <Accordion title="Do you train AI on my code?">
    No. Your code and conversations are not used to train AI models. Your projects remain private and are stored locally on your machine.

## Billing

<AccordionGroup>
  <Accordion title="What's the difference between Free and paid plans?">
    Free plan lets you use your own API keys with a 15 messages/hour limit and 1 deploy per month. Paid plans include credits for AI usage, unlimited messages, and more deploys.
  </Accordion>

  <Accordion title="What are credits and how do they work?">
    Credits are used for AI interactions. Different models cost different amounts — larger models like Claude Opus 4.5 use
