to the first sales, so the Author does not have to enter that money in advance.

However, this minimum amount may be replaced by the one indicated below, when it is higher: 10% of the total amount of sales made by the Author the previous month.

[If you have three Complements for sale for 30 euros each, the minimum to retain will be 60 euros. If the previous month the Author has sold forty Complements for 30 euros, the total sales will be 1200 euros, and therefore 10% is higher and 120 euros will be retained]

The minimum €60 of the commission clause is computed once the guarantee deposit has already been paid.

[If the deposit is €60, commissions will be paid once the balance exceeds €120]

Estimated unit cost.

As an alternative to the guarantee deposit, the withholding of the sales balance is contemplated, as indicated below.

After the third notice, King of App will assume maintenance for all users who have purchased the Plugin or who purchase it later.

King of App, if it deems it appropriate, will cover the costs of this maintenance option by retaining the existing balance and the amounts that accrue from sales, until the actual cost of the hours dedicated is covered.

to maintenance, at which time the Plugin will be terminated.

If the Author decides to assume the maintenance again before this withdrawal occurs, he must pay the cost of the hours that the balance of the sales has not yet covered. The maintenance cost is calculated as €100

(one hundred euros) per hour per man. This balance of hours will be notified to the Author in the user panel.
