FAQ

How do I share a model? Open a model → Share → Create Link. Anyone with the link can view it in a browser — no app needed. Update Model pushes your changes to the same link; Delete Link revokes it instantly.
How long do links live? 7 days on Free, 30 days on Pro. Recreating a link takes two taps.
How do I manage my subscription? Settings → Manage Subscription, or the Subscriptions section of your Apple account. Use Restore Purchases after reinstalling.
