Your numbers, subscriptions, and credits are tied to the email you sign in with. As long as you sign in with the same email you used when you purchased, everything will be there.
If you started in guest mode (“Continue without login”) and later signed in, your purchases are designed to move over to your signed-in account automatically.
If you've signed in with the correct email and something is still missing, contact support and let us know the email you're using — we'll help track it down.
