The App offers the following subscription tiers providing access to premium features: Weekly, Monthly, Annual, and Lifetime. All subscriptions are purchased as in-app purchases through the Apple App Store or Google Play Store.

5.2 Free Trials

Where available, free trials automatically convert to a paid subscription at the end of the trial period unless cancelled at least 24 hours before the trial expires. Free trial eligibility and duration are determined by the relevant app store.

5.3 Billing and Renewal

Weekly, Monthly, and Annual subscriptions automatically renew at the end of each billing period unless cancelled at least 24 hours before the renewal date. Subscription pricing may vary by region and currency. We do not directly process payments -- all billing is handled by the Apple App Store or Google Play Store.

No partial or full refunds will be issued for Lifetime subscriptions in the event of App discontinuation.

5.5 Cancellation

You may cancel your subscription at any time through your device's subscription settings in the Apple App Store or Google Play Store. Cancellation takes effect at the end of the current billing period -- you will retain access to premium features until that date. Deleting the App from your device does not cancel your subscription.

All refund requests are handled exclusively by the Apple App Store or Google Play Store in accordance with their respective refund policies. We do not process refunds directly. Please contact Apple or Google support for refund enquiries.

5.7 Price Changes

We may change subscription pricing at any time. Existing subscribers will be notified of price changes in advance, in accordance with the requirements of the relevant app store. Price changes will not affect the current billing period.
