- Birth year. This is not part of the profile because usually your friends know your age. It's a way to internally know which demography is using the app more. It's the only part of the app that is Ferris focuses instead of user focused. I debated if I just simply add a yyyy-mm-dd input and give the user the benefit of remembering their friends birthdays (as plenty of apps), but the day of birth is way more personal than the year, so I scrapped that part. I maybe need to add a tooltip explaining why I'm asking this. 1950 is just a number I don't think 99% of my users will have.

- Ferristag: it's a secret identifier. If you go to Friends > Add Friend, you can see your Ferristag. You copy and send it.

- Notifications: I went with the option of making the explicit choices, but I if you have no notifications activated you will see a reminder, once that you add a friend. It looks premature to ask for notifications permission before this could be useful. But yes, notification handling is maybe something I could make better.

- Email invites: I thought about this, but finally rejected because it loses the personal touch and it looks spammy most of the time, or that my friend is getting a commission lol. I could rethink this based on feedback.

Thanks!
