Classkraft operates entirely serverless and on-device. All image processing, color quantization, and vectorization occur locally within your browser using a Web Worker. Your source photos and generated booklets are never uploaded to any server. There is no account, no sign-in, and no analytics.
The only data Classkraft stores is a light/dark theme preference and your selected language, saved in your browser's local storage. Nothing else persists between visits.
