Terms

Effective 19 October 2026. Operator: Costwell Tools. Contact: support@plainwarestudio.com.

Free calculators

The calculators are free to use for your own business. They work from the numbers you enter and the method described on each page. You set your own prices.

Workbooks

• Each workbook is a digital download: one zip with an .xlsx file and a quick-start PDF. Nothing is shipped.
• Prices are in Australian dollars and shown GST included where applicable. Purchases on this site are processed by Polar, which acts as merchant of record and handles payment, tax and receipts. Purchases on Etsy follow Etsy's terms.
• Your licence covers use in your own business. Don't resell, share or republish the files.
• Refunds: if a file doesn't work as described, email support@plainwarestudio.com within 14 days of purchase and we fix it or refund you in full. This 14-day promise is in addition to your rights under the Australian Consumer Law, which include a refund or replacement for a major failure.

Liability

To the extent the law allows, our total liability is limited to what you paid us. Nothing in these terms excludes, restricts or modifies rights you have under the Australian Consumer Law or other law that can't be excluded.

Complaints and contact

Email support@plainwarestudio.com. We acknowledge within 7 days and resolve or answer in writing within 30 days. See About & contact.
