No ability to cancel your subscription or delete your account from the app after the free trial (it sucked so I wasn't going to continue using it.) The spelling errors alone made me decide against it, as something meant to protect my privacy and accounts should be run by people who can, at the very least, proofread three sentences. The design is hard to use, the whole app doesn't make much sense, the "button" to access your account in settings doesn't work; it's just poorly made. Use Google.

this app used to work but I nearly lost an account entirely, it just stopped showing codes when i needed one to log in on my computer. Not only that, I couldn't click on a single thing anymore without it forcing ads and promotion for its new subscription service in my face. I was scared there was literally nothing I could do to get into my account. I was very lucky one of my devices happened to still be logged in so I could turn off 2FA and save my account.
