Terms of use

1. Scope

Use is free and voluntary. By signing in with Google or submitting a result you accept these terms. Calculator, planner and methodology can be used without an account; only sections 7 to 10 apply there.

2. What the site does

10kburn.com calculates estimated calorie expenditure from your inputs and offers a planner, a live companion, a leaderboard and a shareable certificate. All figures are estimates based on a disclosed method – not measurements and not medical advice.

3. Account

You need a Google account and must be at least 18 years old. Your display name must not infringe third-party rights, be offensive or impersonate another person. You can delete your account with all data yourself at any time under “Account”.

I may suspend or delete accounts that violate these rules, for example for faked results or abusive names.

4. Leaderboard

An entry is a self-declaration: your total energy for one challenge day as shown by your tracking app, one entry per account and day. Entries must be truthful. Publicly visible are display name, category, level, calorie value, date, split by sport and verification status.

There is no entitlement to be listed or to remain listed. I may remove entries or mark them unverified if they are implausible, the proof does not match or there are signs of manipulation.

5. Proof and verification

Proof is a screenshot of the day's total energy from Apple Health, Samsung Health, Garmin Connect, Google Fit/Fitbit or Polar Flow. The screenshot is checked once automatically (see privacy policy) and not stored. The result is an assessment; edited screenshots, someone else's data or mismatching values lead to rejection. Unclear cases I review by hand, without a deadline and without a claim to a particular decision.

6. Certificate

The certificate is created in your browser and shows your entries. It is not an official document and no confirmation of a measured performance; “Verified” only means your screenshot passed the automatic check. You may share it privately and on social networks, but not alter it so that different content results.

7. Health and personal responsibility

High calorie expenditure in one day puts heavy strain on the body. You take part at your own risk. The site does not replace medical advice; if you have pre-existing conditions, take medication or are unsure, talk to a doctor first and follow the safety notes on the methodology page. Stop immediately at warning signs.

8. Availability and liability

The site is run privately without any guarantee of availability; features may change or be removed. For free use I am liable only for intent and gross negligence and for injury to life, body or health; statutory liability remains unaffected. I give no warranty for the accuracy of the estimates.

9. Changes

I may adapt these terms when the site or the legal situation changes. The current version is published here with its date; I announce material changes at your next sign-in.

10. Applicable law

German law applies. Mandatory consumer protection rules of your country of residence remain unaffected. I am neither obliged nor willing to take part in dispute resolution before a consumer arbitration board.
