Privacy
Wallery is built so that there is nothing to leak. Your photos never leave your device.
Your images
When you add a photo of your wall or a painting, it is read with the browser's FileReader, decoded into an Image, and drawn onto a <canvas> entirely within this browser tab. Wallery makes no network request that carries your image data. There is no server that receives it.
Storage
Wallery does not write your images to localStorage, sessionStorage, IndexedDB, or cookies, and registers no service worker that could cache them. When you refresh or close the page, everything you added is gone.
The download
The only file Wallery produces is the preview image you explicitly download. It is generated in your browser with canvas.toBlob() and includes a small Wallery logo watermark. The temporary link used to save it is revoked immediately afterwards.
Analytics
Wallery does not track or analyse the content of the photos you load.
Theme preference
Even your light/dark choice is kept only in memory for the current session and is forgotten on reload — consistent with keeping nothing.
