Content Sources & Accuracy

Last updated: November 8, 2026

The short version: HWTUTU is an independent reference site, not a professional adviser. Our pages are compiled from publicly available information and AI-assisted drafting, then checked by a human editor. We cannot guarantee that everything is accurate, complete or current. Before you rely on a number, a recommendation or a safety claim, confirm it with the official source or a qualified professional.

How our content is created

Most pages start as a question — how long will this hike take, what does this sleeping-bag rating mean, what belongs in a first-aid kit. We gather public reference material, manufacturer documentation, land-agency guidance and published formulas, then use AI-assisted tools to draft and structure the explanation. A human editor reviews the result for clarity, internal consistency and obvious errors before publishing.

We do not claim first-hand testing of every product, route or technique mentioned on the site. Where a formula is used, it is a published approximation; where a number is shown, it is an estimate from the inputs you provide. The full process is documented in the Editorial Policy and Testing & Methodology.

What we do not promise

  • That every fact, figure, link or product specification is accurate.
  • That the content is complete for your specific trip, body or situation.
  • That regulations, prices, gear models or trail conditions are still current.
  • That a calculator result will match what happens outdoors.

Verify before you rely on it

For anything that matters, go to a primary source:

  • Trails, parks and permits — the official land agency, park authority or local tourism office.
  • Gear — the manufacturer's current specification sheet, manual and safety notices.
  • Weather and conditions — your national weather service and local avalanche or flood warnings.
  • Health and fitness — a doctor, registered dietitian or other qualified healthcare professional.
  • Emergencies — your local emergency number, not a web page.

Health and medical content

BMI, body-fat, hydration, calorie and heart-rate tools are general educational screens. They do not diagnose, treat or rule out any condition, and they are not a substitute for individual medical advice. Never change medication, diet or training because of a number on this site. See our Safety & Medical Disclaimer for the full statement.

Gear and product information

HWTUTU does not sell gear, does not accept payment for product placement and does not currently use affiliate links. Product categories or brand names are used for identification only. See our Affiliate Disclosure. Specifications and availability change constantly, so always check the manufacturer or retailer.

AI disclosure

AI tools are used to draft, outline, translate, summarise and check content. They can produce plausible but wrong statements. We treat AI output as a first draft, not a source of truth, and we correct errors when they are reported. If you spot something that looks wrong, please tell us — see the contact section below.

Copyright and corrections

We aim to write original explanations and to link to sources rather than copy them. If you believe content on this site reproduces your copyrighted work, or is otherwise inaccurate or misleading, email us with the page URL and a short description. We will review the report and correct or remove the material where appropriate.
