Tinder wants to help you support the cause that you care about!
All you have to do is tweet @Tinder and mention a cause of your choice.
It can be the name of a specific charity that supports women or girls or anything of your choice. You have to include the hashtag #FundHerCause. Then you get a code that directs you to a $100 donation to the female-friendly charity you picked on Tinder.fund.
