Please, try this program before buy it.
I need your device serial number to generate the license key for you.
To get it you should:
After purchase of the first license you can get the second license key for free. E.g. you've purchased the Android-version. You can get a license key for another Android or Windows or Linux etc.
Please submit the registration form for the second license key (see notes below).Note. Specify the payment details (date, time, transaction number, etc) of you payment for the first license.
This method works only for Android version of pbchess, installed from Google Play. Just click the "Buy" button in the program to register it!
Complete the registration process.
Contact me if any questions.
We accept bitcoins (BTC) and altcoins (LTC, ETH, DASH, etc). Price is 5$. But as soon as exchange rate is not fixed please first email me me what currency will you use for payment. And I will provide my wallet address and amount to pay.
Sometimes after re-installing your OS (Windows, Linux, OSX) or re-flashing your gadget (Android) your license key is not working any more. There is absolutely nothing to worry about.
All you need is to submit new registration form using THIS LINK.
You need to enter YOUR NEW serial number. In the remark field please specify your old license key to confirm your previous purchase.
I assume that people re-install their OS and re-flash their gadgets not very frequently.
