The web application guess from your name is for fun, not for infringement of privacy. To protect people’s privacy, I have taken the following measures.
The age given is not an accurate age, but an age range. There is 50% of chance that the person in question is within this age range. When the age range is less than 7 years, I increase it to 7 years, so that you can never accurately know that person’s age.
The birth place given is not an accurate one, but a big city to which the person in question is closest. For instance, if the person was born in Ile-de-France, the application will simply give Paris.
Last but not least, do not use this web application with malicious intent.
