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.
- 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.
- 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.
- 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, and nothing about it changes.
