Firmament is a keepsake maker: it computes the sky over a place and date you choose and renders it as a plate to keep, gift, or share. It is provided as-is, for general audiences. Astronomical values are computed for keepsake purposes and are not intended for navigation or any safety-critical use.
Firmament is free to use, with an optional one-time purchase ("Plates"). This is a non-consumable in-app purchase — not a subscription. It does not renew and there are no recurring charges. It removes the watermark and unlocks print-resolution export, your saved library, every plate finish, and the full named-star layer.
Payment is charged to your Apple ID at confirmation of purchase. You can restore the purchase at any time from Settings inside the app. All billing and refunds are handled by Apple.
Plates you create from your own inputs are yours. Firmament claims no rights over them.
The app is provided "as is," without warranties of any kind. To the maximum extent permitted by law, Hadger is not liable for any indirect or consequential damages arising from its use.
