Don't panic! We have of course considered this situation. Here is the solution: Every time someone scans your sticker or via your partner link is forwarded to our website, our intelligent system registers the visitor using many complicated indicators under your partner account. This person's data is stored in our system for a full 90 days each time, and even if the purchase is made after 89 days, you will still receive the commission. The 90-day period starts all over again for each visit from the person. This is how we ensure that you can get the most out of your work.
