Subscription handling

• In-app subscriptions purchased through the App Store / Google Play are processed by Apple / Google; they manage billing, receipts, refunds and the subscription renewal UI. To manage or cancel these subscriptions, users must use their Apple ID / Google Play account subscription settings.
• We do not store full payment card numbers on our servers; payment processors store and process card details.
• We may use subscription management services (e.g., RevenueCat) to manage entitlement and subscription state across platforms.

Auto-renewal & cancellation

• Auto-renewable subscriptions will automatically renew at the end of each subscription period unless you turn off auto-renewal at least 24 hours before the end of the current period. Charges for renewal will occur within 24 hours prior to the end of the current period.

You can cancel your subscription directly from within the app:

5. From there you can Cancel Subscription (or update your plan).
6. Your subscription will remain active until the end of the current billing period. After that, you will not be charged further.

Invoices & receipts

• After each purchase we provide a receipt or invoice. For in-app purchases, Apple/Google issue the official receipt; for website purchases, we email an invoice and store a record in your account.
