What "yours forever" means

Once you buy, the app is installed on your computer and keeps working — with or without us, with or without internet. No server can switch it off.

Buying for a co-op or classroom?

We're happy to sort out multi-computer licensing for homeschool groups, tutors, and classrooms. Get in touch →


Questions before you buy?

Is this really one-time, with no subscription?

Yes. You pay $19.99 once and the app is yours. There is no recurring charge, no "pro" upsell, and no expiry.

Does it need the internet?

Only for the one-time download. After that it runs fully offline, forever.

How many computers can I install it on?

It's licensed for your family's personal computers. If you need it on several machines for a co-op or classroom, just contact us.

What if it's not right for us?

Email us within 60 days and we'll refund you, no questions asked.
