Implementation and verified quality

advanced · Godot-style anchor arithmetic / canvas text measurement / WCAG contrast formula. Quality qualification is in progress. Pro/Flagship quality has not been established.

Before you export

Anchors and safe areas are a conceptual simulation, not a layout pass any engine ran. The contrast ratio is the WCAG formula, a reference number rather than a verdict.

Are my files uploaded?

Nerulio processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.

Will my work be saved automatically?

No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
