Someone mentioned the SafeUP app to me so I decided to check it out. (Haven't downloaded it yet though.) It's supposed to create a community of on-call women "guardians" who are available to stay on a phone call with women users who are walking alone at night, etc. I found the answers to two of their FAQ's interesting:
How does SafeUP make sure that men can’t enter the network and abuse the app?
Male allies are encouraged to share SafeUP with their loved ones; however, in order to preserve the feeling of safety and comfort for all our users we do not allow males into our network. We believe that men are an essential part of the creation of a safer world. In the future we plan to explore ways for men to contribute to SafeUP (with the express permission and consent of our users). Stay tuned and share SafeUP with any and all women you know!
Can members of the the non-binary and genderqueer community join SafeUP?
Our community includes members of the LGBTQ+ community and our verification process is equal for all users. When reviewing a new member we at SafeUP explore whether or not their membership will contribute to the safety of the other members of the community. All new accounts may be verified or not verified for numerous and complex reasons. Each case is evaluated on its own merits.
I wonder if transwomen (male) would be allowed on a case-by-case basis, despite their stating "we do not allow males into our network". Note that their answer to the first question how do they ensure men can't enter doesn't actually answer the question! But at least they don't parrot TWAW or explicitly say that "all women including ciswomen and transwomen are welcome" or some bollocks like that.
