The browser draws the sign, stores drafts and processes selected artwork locally. No account is needed to create a sign. The built-in fonts and cached application support core offline use after the first complete online load.
Photos, handwriting and music do not upload to an application file server. Project backups are files you download and manage yourself. Optional remote rooms relay only validated messages, settings and commands through Cloudflare, and their data is temporary.
Practical features with clear limits
Scenes, templates, brands and bilingual layouts support different uses without requiring paid services. AI is not enabled. There is no paid membership or automatic service upgrade in the product. Remote rooms have explicit daily and session limits.
Device capabilities vary. A browser tab cannot act as an always-running server when the operating system sleeps. Countdown timing depends on the device clock. Fullscreen, keeping a screen awake and video export depend on browser support. The guides explain these boundaries.
