Privacy, plainly.
Trailmix is a group backpacking planner. To plan a trip we hold some information about you and your crew — this page explains what, why, and what we never do with it. Last updated July 6, 2026.
What we collect
Trip organisers create an account with an email address. That's the only account on a trip.
Everyone else joins from an invite link — no account. When you join you add a display name, a tent-mate choice, the gear you're bringing, and a few figures used to work out a fair carry limit (things like body weight, pack experience, and any physical limitations you choose to note).
Invite emails — to bring someone onto a trip, an organiser gives us their email address so we can send them the invite link. We use it only to deliver that invite.
Trip details — the route, dates, camps, rides and shuttle, permits, the shared gear list, and food and water sized to the miles.
Gear photos and messages, if you use them. When you scan your kit with your phone, each photo is used only to identify the gear in it and estimate its weight, then deleted right after — we don't keep the photos. When you ask the trail assistant a question, we keep that conversation so you can pick it back up.
We also collect basic technical data (like your browser type and approximate region) that any website receives when a page loads.
Your body stats stay private
The figures behind your carry limit are used only to calculate how much weight is fair for you to carry. They are never shown to the rest of the crew. Your crew sees the weight you're carrying — for example “Sam carries 31.4 lb” — never the numbers behind it.
How we use it
To build and run your trip page: draw the route, size food and water, split the shared load fairly, and keep the plan in sync as the crew joins and changes. We use your email to send trip-related messages (invites and important updates). We do not sell your information, and we don't use it for advertising.
Where AI comes in
A few features lean on AI: reading your gear photos to identify items, suggesting a trail-specific packing list, and answering questions in the trail assistant. To do that we send the relevant content — a gear photo, a trail name, or the question you asked — to a third-party AI provider, which may run a web search to ground its answer. We never send your private body-stat figures to it. It processes what we send only to return the result to us.
Who we share it with
Only your crew sees your trip, and only the parts described above. Behind the scenes we rely on a small number of service providers to host the app and its database, to deliver email, and to power the AI features above; they process data only on our behalf and only to provide those services. Some are based outside your country, so your information may be handled elsewhere. We may disclose information if the law requires it.
Cookies
We use only the cookies and local storage needed to keep you signed in and remember your preferences. On this marketing site we also use Google Analytics to understand which pages and buttons visitors use, so we can improve the site — it's not used for advertising or ad targeting, and we don't sell or share this data with third parties for their own purposes. You can opt out with Google'sbrowser add-on.
Keeping it safe
We protect your information with encryption in transit, access controls, and reputable hosting providers. Your body-stat figures live in a separate, restricted store that never reaches the app's screens, logs, or API responses. No service is perfectly secure, but we take reasonable steps to guard what you entrust to us.
Keeping it, and deleting it
We keep trip information for as long as the trip is active so your crew can use it. You can ask us to see the data we hold about you, correct it, or delete your account or your data at any time — and we'll remove it unless we're required to keep it. Just email us using the address below.
Children
Trailmix isn't directed at children under 13, and we don't knowingly collect their information.
Changes
We're in beta and still building, so this policy may change. When it does we'll update the date at the top of this page.
