Your content is available based on what the LaterPay Merchant specified.
The availability of your purchased content depends on the content you buy and the Merchant that you purchased it from. If the content has an expiration date, the Merchant will alert you to its availability. For example, the Merchant could say, “buy access to this video for six months.” If there is no expiration stated, presumedly your access is unlimited.
If you have purchased content that you expected to be unlimited and it’s now unavailable, you might want to read “What will happen if a content provider doesn't offer previously purchased content?”
