Mahram Check is a simple web app that allows you to check who is and isn't your mahram. In short, if you are a mahram to someone, it means that it is permissible to have a physical contact with the person. Please note that this explanation is not extensive, and so you should consult your ustadh/ah (Islamic teachers) if you wish to understand more about the term mahram.
Please also note that as of now, the list of relationships in this site is limited to your direct blood relatives only. More complicated relationships might be added to the list in the future, if there is sufficient demand.
