How is transfer quota calculated?

Transfer quota is calculated as follows:

1. Basic Transfer Quota resets at the end of each calendar month and does not roll over. A new Basic Transfer Quota becomes available at the start of the next month.
2. Extra Transfer Quota is usually valid for one year from the purchase date. Any unused quota expires at the end of its validity period.
3. PikPak uses Basic Transfer Quota first. After it is exhausted, PikPak begins using any available Extra Transfer Quota.

You can purchase Extra Transfer Quota when needed.
