What this costs

Every map in the Free column is free, on your own files, with nothing stamped across the figures. Pro is one payment — no subscription, no renewal and no account, because there is no account to renew against.

Pro is on sale. Free stays free.

Pro licences are on sale below. Paying is one payment on Stripe’s checkout page; there is no account to make, and your files still never leave your browser.

The features in the Pro column are marked with a Pro chip where they appear in the app. A Pro licence is what pays for them, and for keeping the free maps free.

Anything in the Free column stays free forever. That is a promise about this list, not about a trial period.

We don’t charge per figure because we can’t see your figures.

What Pro costs

Pro

$129

one payment · 12 months

Twelve months of everything in the Pro column. After that it lapses and the free maps keep working.

Pro, for good

$249

one payment · never expires

The same, with no expiry — including maps not drawn yet.

Team

$599

one payment · lifetime, 5 seats

For a firm rather than a person. One payment, no expiry, five people licensed.

This licence covers 5 installations. Nothing counts them — a key works in any browser it is pasted into — so the number is what was bought rather than a limit we enforce.

What is in each

Feature	Free forever	Pro
Maps	Potentiometric surface Well location map Contour map Plume map Water-level change Hydraulic gradient	Stiff diagram map Trend map
Wells	No limit, and no count kept — your file is never sent anywhere to be counted.	The same. There is nothing to raise.
Export	PNG, SVG and print-to-PDF, at full resolution. DXF, GeoJSON and shapefile — the contours, the hull and the wells as geometry, in your own coordinates. A small “made with gridlad.com” credit in the bottom margin, outside the drawing.	The credit line removed. Every gauging round in one file, drawn and zipped in one go — not built yet.
Workflow	One active site, saved in this browser so closing the tab does not lose it.	Named site templates, with no limit — the same wells, every quarter, for years.

Questions

Can I use this for client work right now, for nothing?: Yes. Every map in the Free column draws from your own file, at full resolution, with no watermark across it and no account. The only mark on a free export is the credit line in the bottom margin, outside the drawing. The two Pro maps draw their example site for free, so you can see exactly what they do before you buy.
Is any of this a subscription?: No. The annual licence is one payment covering twelve months, after which it lapses and the free maps keep working. The other two are one payment and never lapse. Nothing renews by itself, because there is no account for it to renew against.
What is a seat, if nothing counts them?: A licence key is a string you paste in, and it works in any browser you paste it into — there is no device binding and nothing phones home. The five-seat licence is what a firm buys so that five people are properly licensed; it is an honest count rather than an enforced one, and we would rather say so than pretend otherwise.
What happens to my well data?: Nothing. It is read in your browser tab and never sent anywhere — there is no server to send it to. That is also why the price list has no per-figure or per-site line on it.
Where does my well file go?: Nowhere. The privacy page shows how to check that rather than asking you to take our word for it, and help@gridlad.com answers anything it does not.
