FAQ
What happens if I downgrade from Pro to Free?
Nothing is deleted. If you have more watched APIs than the Free plan's limit, the oldest one stays active and the rest are paused (their data and history stay, monitoring just stops) until you upgrade again or remove some.
What payment methods are accepted?
Billing is handled by Polar, which supports major cards and handles tax automatically as Merchant of Record.
Can I cancel any time?
Yes — Pro access continues until the end of your current billing period, then your account moves to Free (with the pause behavior above, not deletion).
