There are a lot of websites on which I login. Many websites offer sign up through fb, twitter, Github etc. I find it difficult to remember through which social account I signed up on a particular website. To solve this problem I developed an Android app on which we can save these details: Name of Account, Linked with (Social Account name), Email address associated to login and retrieve the details anytime. Along with these details I thought of adding the logo of the Social Media account in the app.
Will there be any legal issues I might face for using logos of the websites mentioned in the question.
