Seacove is for crew aged 18 and older, no exceptions. We calculate your age from the date of birth you enter at sign-up, not a checkbox, and we block account creation if it comes out under 18.
On iOS, we also check Apple’s own age signal for your account. If either check finds you’re under 18, sign-up is blocked.
If you believe your account was blocked in error, contact support@seacoveapp.com.
