Some episodes are free. Others need either an active VIP membership or a temporary ad unlock, which you earn by choosing to watch a rewarded advertisement and which expires after the period shown in the app.
VIP is sold as a subscription through Google Play. Google takes the payment; we never see your card details. We only receive confirmation of the purchase so that we can switch the membership on for your account. Unless you cancel, a subscription renews automatically at the end of each period at the price shown in Google Play.
You can cancel at any time in the Google Play app under Payments & subscriptions → Subscriptions. Cancelling stops the next renewal; membership continues until the end of the period already paid for. Refunds are handled by Google Play under its refund policy. If a purchase does not show up in the app, use Profile → Restore purchases.
VIP removes the wait on locked episodes. It is not a promise about the catalogue: because the video is hosted by third parties, a title can become unavailable while your membership is active.
