Tickle v Giggle is an Australian law case regarding the legality of the trans-exclusionary membership policies used on an app platform.

[1][2] In 2020, Sall Grover founded Giggle for Girls, a mobile app designed as a social networking platform for cisgender women.

[3] The name, Giggle, is described as a collective noun for women,[4] with the app presented as catering only to cisgender women, offering a safe online space for them to connect and find support in various areas such as finding roommates, freelancing, emotional support, and activism.

[4][5] Grover has said she was driven to develop a digital platform for cisgender women by her desire to guard against the advances of predatory men, a view that was informed by her experience with misogyny and sexual violence.

[6] To verify users' birth sex, it relied on technology developed by Kairos, a company that offers facial recognition software.
