1. Create your account
Sign up with your email and a password. One adult account holds the whole family, so a parent or guardian signs up, not the student.

Getting started
How subscribing works.
Four steps from signing up to a working subscription, and what to do afterwards when you want to change plan, update a card or stop. If you have just created an account, step 2 is where you are now.
The four steps
2. Verify your email
We send you a link. Open it to confirm the address is yours. Nothing else is needed from you at this point.
3. We approve your account
Every new account is checked by a person before it can sign in, so this step is not instant. We email you as soon as it is done, and there is nothing you need to do while you wait.
4. Choose your plan
Sign in, open your Account page, pick a billing period and choose a plan. You are taken to Stripe to pay, and your access opens up as soon as the payment confirms.
You can pick a plan on the pricing page before you sign up, but nothing is charged until step 4, and you can change your mind about which plan you want at any point before then.
What each plan unlocks
- FreeThe first chapter of every course, plus chapter diagnostics on every chapter. Free forever, no card.
- ProEvery course end to end, Foundation to Year 12, with the full practice bank of 400 questions per unit. One learner.
- PremiumEverything above, plus Mathematics by Topic masterclasses, senior practice exams, revision sheets, up to 5 children on the one plan, priority support and 10% off tutoring.
Prices are on the pricing page, in Australian dollars. Monthly, quarterly and yearly billing are all available, and you can move between them later.
Paying
Choosing a plan sends you to Stripe, our payment provider, on their own secure page. We never see or store your card number. If you have a promotion code, enter it there before you confirm.
Once the payment confirms you are returned to your Account page and the rest of the platform unlocks. That last step is automatic, though it can take a few seconds to catch up. If something still looks locked after a minute, refresh the page.
Changing, pausing or cancelling
Everything after your first payment happens in one place: the Manage billing button on your Account page. It opens the Stripe customer portal, where you can switch between Pro and Premium, change your billing period, update or replace your card, download past invoices, and cancel.
Cancelling takes effect at the end of the period you have already paid for, so you keep full access until then and are not charged again. Switching plan mid-period is pro-rated automatically. The details, including how billing errors are handled, are in the Refund & Cancellation Policy.
Common questions
Why do I have to wait for approval?
PiGrids accounts are for adults, and we check each one by hand before it opens. It is a small step that keeps the platform safe for the children learning on it. You are emailed as soon as your account is approved.
I was approved. Where do I actually pay?
Sign in, then open your Account page from the menu. The Subscription section at the top has a billing period selector and a button for each plan. Choosing one takes you to Stripe.
Do you store my card details?
No. Payment happens on Stripe's own hosted page and your card never touches our servers. If you have a promotion code, you enter it there too.
Can I try it before paying?
Yes. If your account has never had a plan, your Account page offers a 14-day free trial with full Premium access and no card required. It is one trial per account.
How do I cancel?
Open your Account page and choose Manage billing. That opens the Stripe portal, where you can cancel in a couple of clicks. You keep access until the end of the period you have already paid for.
