8. Cancellation by Customer ("3 clicks")
You can cancel anytime via the dedicated feature in the app (Settings › Subscription), which redirects to the Stripe Customer Portal to manage your subscription (cancellation, payment method update, etc.). <strong>Monthly plan:</strong> cancellation effective at end of current monthly period. <strong>Annual plan:</strong> cancellation effective at end of current annual period. <strong>Lifetime plan:</strong> no cancellation needed — your license is perpetual with no recurring charge.

No clause limits our liability for gross negligence, fraud, harm to life/physical integrity, or mandatory legal warranties.
14. Force Majeure
Neither party is liable for failure due to an external, irresistible and unforeseeable event (e.g., general network failure, disasters, administrative decisions, conflicts, etc.).
