What counts as a chart?
Every distinct chart name in any of your projects. Data points beyond the per-chart limit roll off the oldest first, but daily summaries are kept forever.
What happens if I cancel Pro?
You keep Pro until the end of the period you paid for, then drop to the Free limits. Nothing is deleted; charts over the limit stop accepting new values until you're under it.
Can I get my data out?
Yes. Every project can be exported as CSV (raw points or daily summaries) from its settings page.
Do I need a card for Free?
No.
