Terms & Conditions

The rules for using Don Marketer and buying the PDF guides. Short, with nothing buried.

The short version

  • The calculator and glossary are free and informational.
  • Guides are a one-time purchase: no subscription, no auto-renewal.
  • EU consumers get a 14-day withdrawal right unless they asked for instant delivery.

Who runs this

Don Marketer is operated by Michal Krčmář, business ID 87736926, based in the Czech Republic. Contact: dm@donmarketer.com.

What the site offers

Free tools (the marketing calculator, glossary, articles) and paid PDF guides. Calculator output is an automatically generated estimate based on common market ratios, not a guarantee of results. The budget decision stays yours.

Buying a guide

  • A one-time purchase of a single file. No subscription and no automatic renewal.
  • Prices shown at the time of order apply; taxes are shown where required.
  • You get the file to download or by email right after payment.
  • The file is for you and your company: don't republish or resell it.

Refunds and withdrawal

EU and Czech consumers may withdraw within 14 days without giving a reason; for digital content delivered immediately that right ends once you have expressly agreed to instant delivery and acknowledged the loss of the withdrawal right: a separate, never pre-ticked checkbox at checkout. If a file doesn't work or isn't what was described, email me and I will fix it or refund you.

Liability

The content is field-tested know-how, not a promise of specific business results. I am not liable for decisions you make based on it.

Your data

How I handle personal information is described in the Privacy Policy.

SMS Terms

Don Marketer offers optional SMS updates about your purchase, download links and occasional marketing messages. Opt-in is voluntary and is never required to complete a purchase.

By checking the SMS consent box, you agree to receive text messages from Don Marketer. Message frequency varies. Message and data rates may apply.

Reply HELP for help or STOP to cancel at any time.

A sensible starting point, not legal advice. Have a lawyer review these terms before selling into the US.
