Terms

These terms cover getstemwise.com, its free tools, the live demo and the Founding Grower offer. Stemwise is a small business run by Wren Calloway; you can reach us at hello@getstemwise.com. See also our privacy policy.

The free tools and guides

The calculators, the demo and the guides are free to use, with no account. Their figures are planning estimates built from the numbers you enter and from published typical yields. Weather, varieties, pests and your own growing conditions change real results, so treat every figure as a starting point for your own judgement, not a guarantee of what a bed will produce or what a share will earn.

The Founding Grower offer

Fair use

Please don’t try to break, overload or scrape the site, and don’t use shared estimate links to send anything unlawful or misleading.

No warranty

The site and tools are provided as they are, and we can’t promise they will always be available or free of errors. To the extent the law allows, our total liability to you is limited to what you paid us. Nothing here limits any right you have under consumer protection law that cannot be excluded.

Changes

If these terms change, the date at the top changes too. A change never takes away a refund or lifetime access you have already paid for.
