Overview
PalettePreview is a free, browser-based color palette generator. We designed it to be useful without collecting personal information. This page explains what is and isn't stored when you use the tool.
Data we don't collect
PalettePreview does not require an account. We do not collect names, email addresses, or payment information. Palettes you generate, save, or extract from images are processed entirely in your browser.
Local storage
Your saved palettes and recent palette history are stored in your browser's localStorage so they survive page reloads. This data never leaves your device. Clearing your browser storage will remove it.
Image extraction
When you upload an image to extract a palette, the image is processed locally using the HTML canvas API. It is not uploaded to any server.
Analytics
If anonymous usage analytics are enabled by the site host, only aggregate metrics such as page views may be collected. No palette content is transmitted.
