Just a small correction, the math is wrong. If I understood the terms of the license correctly, if your product costs €1, Nokia's cut is 50%+. You're getting (near) 70% only in the best case scenario (fine print, eh ?).
4.3. Nokia shall pay You seventy percent (70%) of the Net Revenue attributable to purchases of Your Content by end users.
4.3.1. For purchases made by credit card, “Net Revenue” shall mean the purchase price paid for Your Content by the end user, net of returns, refunds and bad debt, less all applicable taxes levied on sales, consumption, or based on revenue, regardless of what that tax is called.
4.3.2. For purchases made via operator billing, “Net Revenue” shall mean the purchase price actually received by Nokia for Your Content from the end user, net of returns, refunds and bad debt, less all applicable taxes levied on sales, consumption, or based on revenue, regardless of what that tax is called, and fixed aggregate billing charges.
4.4 [...] if the total amount payable to You is less than five hundred Euros (€ 500), Nokia shall have the right to withhold payment until the next regularly scheduled
quarterly payment date on which the amount payable to You equals or exceeds five hundred Euros (€ 500).
