Making a game?

Frequently asked questions
Does HEIC conversion need the internet?
It may need a first-time decoder download from jsDelivr. The photo is decoded on your device.
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.
