What screenshot inputs are required?

Clean simulator captures in PNG format are required. The studio composites each capture into the chosen device frame and applies your typography, layout and theme.

Can a project be saved and resumed later?

Yes. Authenticated users can save projects to the cloud, name them, and open them again from any device. Autosave runs every 30 seconds during an active session and uploads only the screenshot bytes that have actually changed. The Free tier supports one saved project; the Pro tier supports twenty.

Is the export compatible with fastlane?

Yes. The export bundle uses the exact directory layout expected by fastlane deliver and supply, including locale and device folders. iOS and Google Play screenshots may be mixed within a single bundle without further reorganisation.

Can multiple device sizes be rendered together?

Yes. Any combination of iOS 6.9, 6.7, 6.5 and Google Play may be selected. A single render produces every selected size and packages them in one bundle.

How customisable is the typography?

Each project supports an arbitrary number of named text fields. Within each field, individual character spans may be styled with their own font, size, weight, colour, italics, underline and alignment. More than 30 Google Fonts are available out of the box.

Where is data stored?

Render output and project assets are stored in Cloudflare R2 under the European Union jurisdiction (primary copy in Western Europe). Accounts, render history, and billing data sit in Postgres on a Contabo VPS in Düsseldorf, EU. Render outputs are removed after 24 hours; screenshots associated with saved projects are retained for the lifetime of the project. No training is performed on customer data, and the studio interface uses no tracking cookies.
