Frequently asked questions

Can I try it before I buy?

Yes. The free demo is the real app, not a video or a mockup. It's capped to 2 growing spaces and 3 bags, and nothing you enter is saved: closing the tab clears it. Calendar downloads, backups and printing are in the full version. Buy to remove the cap and keep what you build.

Is this a subscription?

$19.00, once. No account is created, so there is nothing to cancel, and no recurring charge, ever.

What exactly do I get?

Two things from the same purchase: a single HTML file you download and own, and an installable copy of the same app for your phone's home screen. Either one works fully offline after the first load. The download link is on the page you land on after paying, and in your receipt email.

Does it work without internet?

Yes, after the first load. Everything works with no connection: there's nothing on the other end for it to talk to.

Where does my data go?

Nowhere. It stays on your device, in the browser you use the app in. HarvestMath doesn't run a server that sees it. To move to another phone or computer, save a backup file from the More tab and restore it there.

What about HarvestMath Garden?

HarvestMath Garden plans your whole garden in one place, with this app's engine inside it, plus 5 more apps. Pick it above the payment buttons to buy it instead, for $49. Already bought this app? What you paid counts toward it: the Garden costs you $30 (never less than $30), and your receipt email has an upgrade link with your order filled in.

Is there a refund?

No refunds for a change of mind: the free demo is the real app (just capped, and it doesn't save), so you can see exactly how it works before you pay. If something is broken, or you were charged by mistake, email hello@harvestmath.com and we'll make it right.
