Terms of Service


My Android apps requires system version 4.1 or higher. My iOS apps requires version 8.0 or higher. I don’t work with other operative systems at this moment.

At this moment all my apps are FREE, with advertisement. However you can buy NoAds versions (without advertisement) for a minimum price. For European people, Google Play will already include VAT in al the prices.

If your country laws disallow the usage of any of our apps then you are not allowed to use that app. Please let me know in that case and I will ban your country for that app. No problem.


Refunds are not allowed by default, unless you tell me that there is a special local law that forces me to do it, or unless you contact me and you tell me a good reason for it.


Please only use email to contact me. This is the contact email: daniel@blackdevelopers.net
