Every install starts with a 14-day trial of Pro. No card, no account. Prices in US dollars; local tax is added at checkout where it applies.
Five or more users: email support@tidyfieldapps.com for a volume price and a single invoice. Keys can be deactivated and moved between people at any time.
Email support@tidyfieldapps.com within 14 days of a purchase or renewal for a full refund. Payments and refunds are handled by Lemon Squeezy, our reseller and merchant of record.
After purchase you receive a licence key by email. If you have not added the add-in to Excel yet, follow the install steps first (about a minute). Then open Tidyfield Compare in Excel, click License, paste the key, and Pro is on. The add-in checks the key once a week and keeps working offline for 30 days. The check sends the key and a device name; it never sends workbook data.
