Account and plans

What the free and Pro plans include and what happens at a limit, API keys for reading your feeds from other software, and the account settings.

Everything about the account itself: the plan's limits, the keys that let other software read your reader, the password, and deleting the account.

Plans and limits
Free and Pro side by side, feeds, refresh interval, history, the crawler, manual refreshes and API keys, what happens at a limit, and how to move to Pro.
API keys
A key lets other software read and change your reader through the REST API: feeds, counters, entries, OPML. Keys are made in Settings and sent as a header.
Account settings
Settings → Account shows the address, the plan and the date you joined, changes the password, and deletes the account together with everything it holds.
