Your data

Your logbook is yours.

A plain summary of what Crux captures and what it never does. The full detail is in the privacy policy.

What Crux captures
  • What you log. Climbs, workouts, food, weight and photos.
  • What the watch measures. Attempts, height, rest and heart rate during a session.
  • Apple Health, if you connect it. Steps, sleep, heart rate and workouts.
  • Location, if you allow it. Only when you log, to match your gym.
  • How the app is used. Which screens open. You can switch this off.
  • Crash reports. So faults can be fixed.
What Crux never does
  • Sell your data.
  • Show adverts or share data with advertisers.
  • Let your data train AI models.
  • Put training or health figures in analytics.
  • Track your location in the background.
  • Show your logbook to anyone unless you share it.

Questions

Does Crux sell my data?

No. Crux does not sell data and does not show adverts.

Is my data used to train AI models?

No. Coach requests go to Anthropic under terms for API customers, which do not allow training on that data.

What does the coach see?

Only what a feature needs for that one request, such as recent sessions, effort ratings, goals and recovery figures. Your email address and password are never sent.

Can other people see my climbs?

Not unless you share them. You choose each time you share a session to a crew, accept a tag or switch on a public profile.

Can my gym see what I do?

No. Gyms see anonymous totals, and only from climbers who opted in. Totals are hidden until at least five climbers are included.

Does Crux track my location?

No. With your permission, Crux checks your location when you log, to match the session to your gym. It does not track you in the background.

Does this website use cookies?

No. This site sets no cookies and runs no analytics or advertising scripts.

How do I delete everything?

Open Settings in the app and choose Delete account. It is immediate and cannot be undone. Your analytics profile is deleted at the same time.

How do I get a copy of my data?
