When paid access becomes active
The application applies subscription and plan changes when it receives and processes the corresponding verified Paddle webhook. Completing checkout and seeing the return page does not itself prove activation. The code does not establish a general rule that all upgrades wait until the next billing cycle.
Cancellation and plan changes
Cancellation is requested for the next billing period through Paddle. Check your account and checkout details for actual plan-change timing and charges. If a change is not reflected after payment, contact support.
Taxes and checkout
Paddle processes checkout. Review the currency, taxes and final total shown there before paying; the public plan price alone does not establish a tax-inclusive amount.
