Terms of Use

Effective November 11, 2026

These terms apply when you use this website or buy and use a Modicum Explorer audio tour. Modicum Explorer is a brand of Modicum International LLC, a California company based in Napa ("we", "us"). By buying or using a tour, you agree to these terms.

1. What you're buying

Each tour is a self-guided audio tour, delivered digitally. After you pay, the tour opens on your device and we email you a link to it. The tour plays in your phone's web browser; no app is needed. One purchase covers one tour, for your personal use. Your link keeps working for as long as we offer that tour.

2. Prices and payment

Prices are shown in US dollars (USD) and include everything you pay us. Payments are processed securely by Stripe.

3. All sales are final

Because tours are delivered instantly, all sales are final and we don't offer refunds. Please play the free preview before you buy. See our Refund Policy.

4. Your use of the tours

Tours are for your own personal, non-commercial use. Please don't copy, record, share, resell or publicly play the tours or your link. All audio, text and images belong to Modicum International LLC or its licensors.

5. Stay safe

You're responsible for your own safety while using a tour. Stay aware of your surroundings, traffic, cyclists and weather; keep the volume low enough to hear what's around you; and follow all posted rules and the instructions of staff and officials. Never handle your phone while driving: on driving tours, set the tour up before you leave or let a passenger run it.

6. Site entry

Buying a tour doesn't include entry, tickets or access to any site. Please follow the opening hours and rules of each place you visit.

7. Tour content

Our tours share history and stories for general interest and enjoyment. We work to keep them accurate, but historical accounts differ and details can change, so we don't guarantee that every statement is complete or correct.

8. Availability

You need a compatible phone and an internet connection to buy and download a tour. We provide the service "as is" and can't promise it will always be uninterrupted or error-free. We may update tours to improve them.

9. Limit of liability

To the fullest extent the law allows, we aren't liable for indirect or consequential losses, and our total liability to you for any claim about a tour is limited to the amount you paid for it. Nothing in these terms limits liability that can't be limited by law.

10. Changes to these terms

We may update these terms. The version on this page when you buy applies to your purchase.

11. Governing law

These terms are governed by the laws of the State of California.
