Bonsai is sold via the App Store with Apple's standard EULA (apple.com/legal/.../stdeula).
A one-time purchase of $19.99 unlocks Bonsai Pro: unlimited trees, species-specific care templates, full photo timeline, training-wire reminders, and CSV/PDF export. Not a subscription — does not auto-renew.
Refunds are handled by Apple. Contact Apple Support inside the App Store.
