Everything you need to design App Store screenshots is free. Upgrade only when you want to remove the watermark and go bigger.
Yes. The free plan is full-featured for designing App Store screenshots, mockups, and videos; exports just carry a small "Made with ScreenForge" watermark and sets are capped at 3 screens.
Pro is a subscription billed securely through Stripe, monthly (€3) or annually (€18). You can cancel anytime from the "Manage subscription" button in the studio; you keep Pro until the period ends.
Only for Pro. The free studio is completely anonymous. To upgrade, you sign in with a one-time link sent to your email, no password.
No. ScreenForge runs entirely in your browser; all rendering and video encoding happen on your machine, so your screenshots never leave it.
