Privacy

Custos does not require an account and does not use a Custos-operated backend server. Product URLs, names, prices, variants, tracking settings, target prices, and price history are stored locally in your browser.

To check prices, Custos may connect directly from your browser to product pages that you have chosen to track.

Custos does not sell your information, use advertising trackers, or transmit your browsing history to a Custos server.
