# FAQ

> Platforms, your data, notifications, and the honest limits of Finity.

<AccordionGroup>
  <Accordion title="What platforms does Finity run on?">
    iOS, Android, the web (as an installable PWA), and desktop for Windows, macOS and Linux. It's one
    app built to work the same everywhere, with your account syncing your data across all of them.
  </Accordion>

  <Accordion title="Does it work offline?">
    Yes. Finity is offline-first — everything is stored locally and works with no connection. Sync
    runs in the background when you're back online.
  </Accordion>

  <Accordion title="Where is my data stored?">
    On your device first, and synced to your own account so it appears on your other devices. Signing
    out clears the local copy on that device.
  </Accordion>

  <Accordion title="Do I need to pay?">
    No. Finity is free to use. Pro (or a one-time Lifetime purchase) adds the AI recaps, character
    readings, and email reminders — see [Pricing](/finity/pricing).
  </Accordion>

  <Accordion title="How do reminders work?">
    Local notifications are scheduled on your device on every plan. Email reminders are sent from the
    server on Pro, for the countdowns you've asked to be reminded about.
  </Accordion>

  <Accordion title="Is the life-in-weeks grid a prediction?">
    No. It's seeded with regional life-expectancy data to give a realistic horizon, but it's a tool
    for perspective — a canvas you annotate, not a verdict.
