redline marks up chart screenshots. This page covers the website and the redline browser extension.

What we receive

Only the image you choose to mark: a file you drop or paste on the website, or the area of a tab you select after clicking the extension. The extension captures the visible tab only at that moment, after your click or shortcut, and sends only the selected area.

What happens to it

The image is sent to our server and passed to Anthropic’s Claude API, which returns the positions of the lines and labels. We don’t store the image or the result after the response is sent, and we don’t use them to train anything. Anthropic processes the request under its own commercial terms.

What we don’t collect

No account, no wallet, no browsing history, no page content beyond the selected image, no analytics cookies. The extension stores one setting in your browser and nothing else.

Limits and logs

To keep the service usable we count requests per IP address in memory for one hour to apply rate limits. Server error logs may hold an IP address and a timestamp for up to 14 days.

Not advice

Markups describe structure visible in an image. They are not financial advice and say nothing about future prices.
