Before you pay

# Three things, then Stripe.

Two pounds, once, and it adds every other phone in the house. Here is what happens next, so that none of it is a surprise.

1. **Do this on the phone that has your log.** Stripe brings you back to it and your entries are exactly where you left them. A laptop works too, but then you'll be typing the code onto your phone afterwards.
2. **You'll be shown a sync code, once.** Let your phone save it to your passwords when it offers. It's the key your entries are encrypted with, it never reaches me, and it's the one thing I can't send you again.
3. **Put that code on the other phone.** That's the whole of what the £2 buys, and it takes about a minute.

Stripe takes the card and emails the receipt. I never see either. Changed your mind? [Back to your log](https://app.usebabybrain.app/), and nothing about it changes.
