Opt out from the project


Having read the project description and the frequently asked questions, you might come to the conclusion that you don't want the data of your own devices to be collected. Although we informed you about the anonymity of the way we deal with your data, it is your right to say no and make the choice not to share your data. This is easy: fill in the MAC address of your phone or tablet below and it will be filtered out. Please fill it in, into the window, exactly like your phone supplies it to you, including the ' : ' signs.
