How upgrading works

  1. Pick a plan and pay

    Whoever pays makes a quick account first, so the plan, the code and billing stay in one place.

  2. Get your code

    It's on the page right after you pay, and saved in My account.

  3. Your theoremEd picks it up

    Chrome: by itself, while that page is open. Mac: the … menu → Enter or change code. Phone: open the link on that page.

Questions about upgrading

Do I have to reinstall anything?

No. You keep using the same app. The plan's questions start the moment your code goes in.

Does one plan cover all my devices?

Yes. Use the same code on Chrome, a Mac and a phone.

Can I switch plans or cancel?

Any time, from My account, on Stripe's secure page.

Already paid and lost your code?

Sign in to My account. Your code is there.
