Terms of Service — Double Fathom

Last updated: October 23, 2026

Welcome to Double Fathom. These terms cover doublefathom.com and the planning services we offer there. We've written them in plain language — the short version is: be honest with us, and we'll be honest with you.

The free Mission Briefing

Our free Mission Briefing is a single, fixed sample itinerary — the Raja Ampat example you can browse without signing up. It shows how we structure a snorkeling trip plan, with real booking links. It is a sample, not custom planning: it isn't tailored to your dates, budget, or fitness, and we don't build a personal plan for you at this tier.

The Concierge tier

The Concierge tier is a one-time purchase of $29 per trip, paid securely through Stripe (we never see your card details). For that you get a personalized snorkeling itinerary built around your trip, the ability to re-plan it as much as you like while we're building it, chat support, a packing list, our operator picks, and an offline PDF to take with you. It's a one-time purchase — nothing recurring, and we don't store your card.

Refunds

If a Concierge purchase isn't what you hoped for, email us within 14 days of buying and we'll refund it in full — no questions asked. Just write to [email protected] and we'll handle it.

Affiliate links

Some links on the site — to tours, flights, hotels, and gear — are affiliate links. If you book or buy through one, Double Fathom may earn a commission. It costs you nothing extra: the price is the same as if you'd gone there directly. We only link to things we'd put in our own trip plan.

Our itineraries are AI-assisted

Itineraries and plans on Double Fathom are generated by software and curated by humans. That means they're a strong starting point, not a guarantee: seasons shift, operators close, rules change. Please verify the critical details yourself — visas, health requirements, safety conditions, and opening times — with official sources (government sites, your operator, your airline) before you book or travel.

Intellectual property & acceptable use

The content on this site — itineraries, guides, images, and text — belongs to Double Fathom. You're welcome to use it for planning your own travels. Please don't republish, resell, or scrape it, and don't use the site or the Concierge portal in a way that breaks the law or degrades the service for others. If you share a link to a page, thank you — that's always allowed.

Limitation of liability

Everything on Double Fathom is provided in good faith, as-is. Travel is inherently unpredictable: weather, operators, borders, and reefs change without warning. To the fullest extent permitted by law, Double Fathom isn't liable for losses, costs, or damages arising from your use of the site, the free sample, or a Concierge itinerary — including anything that happens on your trip. Always confirm critical details with official sources before you travel.
