Each time PageDiff visits a monitored page to look for changes. Your plan's monthly check allowance is shared across all your monitors and resets each billing month.
Yes — upgrade or downgrade anytime from your dashboard. Changes apply immediately and are prorated (you're charged or credited the difference); no new checkout.
At your monitor cap, you'll be prompted to upgrade to add more. If you use up your monthly checks, checking pauses until your next billing month (or upgrade for a higher allowance). To move to a smaller plan, first get within its monitor limit.
Billing is handled by Lemon Squeezy (our merchant of record); refund requests follow their policy — just contact us.
Prices are in USD; any applicable VAT/sales tax is calculated at checkout by Lemon Squeezy.
