Terms of use

The terms for using the website chalkaholics-climbing.com and the Chalkaholics web app.

Last updated: 26 July 2026

1. Scope

These terms govern the use of the website chalkaholics-climbing.com and of the web application reachable through it at app.chalkaholics-climbing.com (together “Chalkaholics”).

The provider is Christian Karner, 1230 Vienna, Austria (the “provider”). The full details are given in the legal notice.

By using Chalkaholics you agree to these terms. Conflicting terms do not become part of the agreement.

2. Description of the service

Chalkaholics is a digital climbing diary. Registered users can in particular:

  • log ascents of routes and boulder problems in various grading scales, optionally with a photo
  • call up analyses by week, month and year, with flash ascents shown separately
  • view a grade pyramid and the course of their own development
  • link up with friends via a unique identifier, share routes, compare progress and view a ranking within their own friends list
  • export all logged routes as a CSV file

Use is currently free of charge. There is no entitlement to it remaining free permanently; any change would be announced in good time beforehand and would never apply retroactively.

3. No entitlement to availability

Chalkaholics is run as a spare-time project without any intent to make a profit. No particular level of availability is promised.

The service may be temporarily unreachable due to maintenance, technical faults or circumstances outside the provider's control. The provider reserves the right to discontinue operation. In that case this will be announced with reasonable notice so that you can secure your data using the CSV export.

Please do not treat Chalkaholics as the only place your training data is stored. The export function is open to you at any time — use it regularly.

4. User account

An account is required for the web application. The following applies:

  • The details given on registration must be accurate.
  • Login credentials must be kept secret and must not be passed on.
  • The provider must be notified if unauthorised use is suspected.
  • An account may only be used by a single person.
  • Use is permitted from the age of 14. Younger people need the consent of a parent or guardian.

You can delete your account at any time. Doing so also removes the associated route data.

5. User content

You retain all rights to the content you post — in particular to photos you upload. You merely grant the provider the non-exclusive, geographically unlimited right to store this content and display it within the service, that is to you yourself and to the friends you have linked up with. No use beyond that, in particular for advertising purposes, takes place.

You warrant that you hold the necessary rights to the content you post. In particular, content is not permitted that

  • infringes third-party rights, such as copyright or personality rights
  • violates applicable law
  • is insulting, threatening or discriminatory
  • contains advertising or plainly bears no relation to climbing

Photos of other people may only be uploaded with their consent.

6. Prohibited use

The following in particular are not permitted:

  • automated extraction of content, unless expressly allowed
  • attempts to gain access to other people's accounts or to data not intended for you
  • acts that impair the availability of the service, such as mass automated requests
  • circumventing security measures
  • using the service to distribute malware

In the event of serious or repeated breaches, the provider may suspend or delete the account concerned. Before a suspension, an opportunity to comment will be given where reasonable in the circumstances.

7. Sport, training and health

The content in the knowledge section and the calculators provided serve as general information.

They replace neither individual training advice nor a medical or physiotherapeutic assessment. This applies especially to articles on finger strength training, injuries and nutrition.

Climbing and bouldering carry an inherent risk of injury. All decisions about training and practising the sport are yours to make on your own responsibility. In case of complaints, pain or after an injury, expert advice must be sought before training is resumed.

Conversions between grading scales are approximations. There is no exact correspondence between the systems, and published comparison tables differ from one another.

8. Liability

The provider is liable without limitation for intent and gross negligence, and for injury to life, body or health.

In the case of slight negligence the provider is liable only for the breach of material contractual obligations, that is obligations whose fulfilment makes proper use possible in the first place and on whose observance you may rely. In that case liability is limited to the foreseeable damage typical of this kind of contract.

For loss of data the provider is liable only to the extent that would have arisen had you made proper and regular backups. The CSV export is available for this at any time.

Mandatory statutory provisions, in particular under the Austrian Consumer Protection Act and the Product Liability Act, remain unaffected.

9. References to external websites

Chalkaholics contains references to external websites. The respective provider is solely responsible for their content. Ongoing checks without specific grounds do not take place.

10. The provider's rights

All content on this website — text, design, source code, calculators and graphics — is protected by copyright unless it originates from users. Any use beyond the limits permitted by law requires prior written consent.

11. Changes to these terms

These terms may be adjusted, for example when new functions are added or the legal position changes. You will be informed in advance and in an appropriate form about material changes. If you do not object within the stated period and continue to use the service, the amended terms are deemed accepted. You will be separately alerted to this effect in the notification.

12. Applicable law and place of jurisdiction

Austrian law applies, excluding the referral rules of private international law and the UN Convention on Contracts for the International Sale of Goods.

If you are a consumer with your habitual residence in the European Union, the mandatory protective provisions of your country of residence remain unaffected. For claims against you, the general place of jurisdiction at your domicile is decisive.

13. Final provisions

Should any provision of these terms be or become invalid, the validity of the remaining provisions is unaffected.

The German-language version of these terms is the authoritative one. Translations serve solely to aid understanding.
