Draftsman Ruler and Color Picker does not collect, transmit, or share any data. All settings and saved colour swatches are stored locally in your browser using the storage.local API and never leave your device. The extension makes no network requests and contains no analytics or tracking. Pixels read by the eyedropper and element styles read by the inspector are processed only in memory on your device; they are not stored or sent anywhere.
