Unlocking…

What just happened

• The unlock is stored in this browser, on this machine. No account was created and nothing about you is held here.
• New computer, or cleared your browsing data? Email from the address you paid with and we will put it back — usually the same day.
• Every pane in the job gets a label now, not the first twelve.
• The rack holds 400 offcuts instead of 25, and stays searchable.
• Every job you save is kept, and your own line replaces ours on the labels and the documents.
• There is nothing to renew and nothing to cancel. One payment, and the unlock stays. If you were charged but Pro did not unlock, one email sorts it out or refunds you in full.

Something not right? The unlock can be switched off again here.

Keep this purchase in your account

You are signed in to a SyntaxFlow account that does not have this Pro yet. Type the email you paid with and the last four digits of the card: we check them with Stripe and keep the purchase in your account, so Pro is there on every device you sign in on.

Why you are seeing this

This page unlocks Pro when Stripe sends you back to it after a payment. You arrived without that, which normally means one of three harmless things:

• You have not bought it yet. The pricing page has the button, and explains exactly what the €29 unlock does and does not cover.
• You bought it and lost the unlock — new machine, cleared browsing data, a different browser. Email from the address you paid with and we will restore it.
• You paid just now and something went wrong on the way back. Same address, same answer, and we will check the payment at our end.

Nothing you need is behind this page: every calculator, every formula and every standard on this site is free and always was. Carry on using them.

Type the email you paid with and the last four digits of the card. We check them with Stripe and nothing else: your details are not stored, and the answer is the same whether the email or the digits are wrong.
