Reading progress

The site can remember which articles you have read. They are then marked with ✓ on the timeline, and each year shows how much of it you have already covered.

How it works

• An article counts as read when you reach the end of its text. Below the text you can also mark it by hand, or undo the mark.
• Your progress is stored only in this browser, on this device. It is never sent anywhere: there are no user accounts and no analytics that read it.
• An article read in English counts as read in the Polish edition too, and the other way round.
• Clearing the browser's data, or private browsing, removes it.
