Real questions, straight answers. If it's not here, a human is one click away — no bot, no runaround.

Getting started — the basics

So what’s a Stack, exactly?

A short course made of Bricks — ten-minute lessons. Finish the Bricks, finish the Stack. No filler, no 90-minute video you secretly watch at 1.5×.

How long will it take me?

Most Stacks run under two hours total, in ten-minute Bricks you do on your phone between everything else. Stop and start whenever — we hold your place.

Do I need anything special?

A phone or a laptop. That’s the whole kit. No textbook, no download, no “please install our app”.

Pricing & billing — the honest bit

Is the free plan actually free?

Yes. One full Stack, forever, no credit card. We’d rather you try it than trust a brochure.

Can I cancel anytime?

Anytime, in two clicks. No phone call, no “are you sure?” maze, no surprise discount to guilt you into staying.

What does yearly actually save me?

Two months — yearly is the price of ten. Flip the toggle on the pricing page and watch the number drop.

Certificates — but do they count?

Are the certificates worth anything?

They’re built so an employer can tell exactly what you can do — four levels, from sound understanding to expert judgement. Not a “you watched a video” badge.

How do I actually get one?

Finish a Stack and it’s issued automatically. It lives in Your Courses — download the PDF whenever you need it.

Teams & schools — the bulk stuff

Can I put my team or class on this?

Yes — volume pricing, an admin dashboard, single sign-on and shared progress. Message us and we’ll sort a quote.

Do you build custom Stacks?

On the Team plan, yes. Tell us what your people need to learn and we’ll scope it with you.

That's the lot — what else you got?
