Last updated November 9, 2026

The short version

The tools work in your browser. Images, logos, text and colors you enter are not sent to our servers. We do not have user accounts. Advertising and analytics partners may set cookies, as described below.

Data the tools handle

  • Images (color blindness simulator, CSS filter generator) and logos (QR generator) are read and processed on your device and are never uploaded.
  • QR code content, including Wi-Fi passwords, is turned into an image in your browser. It is not stored or sent anywhere.
  • Some tools put their settings in the page address so a link can be shared. Wi-Fi passwords and other QR content are never put in the address.

Stored on your device

We use your browser's local storage for the Color Shelf, saved sizes and your theme choice. This data stays on your device; clearing your browser's site data removes it.

Advertising

We use Google AdSense to show ads. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can opt out of personalised advertising in Google Ads Settings. Learn how Google uses information from sites that use its services at policies.google.com. Visitors in the European Economic Area, the UK and Switzerland are asked for consent through a certified consent message before personalised ads are shown.

Analytics

We use Google Analytics to count visits and see which tools are used, so we know what to improve. It collects data such as pages viewed, approximate location and device type. It does not receive anything you enter into the tools.
