Local project data
Showduino Studio and HauntSync can store projects, device inventories, autosaves and interface preferences in browser storage. Export important productions as `.shdo` backups before clearing browser site data.
Account and cloud services
Where account or cloud features are enabled, they are used to provide signed-in project access and related Showduino services. Cloud services are separate from the live P4 Show Engine runtime and are not required to keep a loaded show running.
Payments
No current Showduino hardware purchase or paid subscription service is being offered through this development website unless a specific page clearly states otherwise.
Support messages
The support form prepares a message in your own email application. The website does not upload the message before you choose to send it.
Third-party services
Some website functions and links may use external providers such as source-code hosting, content delivery or account infrastructure. Their own privacy terms apply to data handled by those services.
