OpenCoach License Agreement
Version 1.0
Copyright (c) 2026 OpenCoach / Level Ten

Applies to:
- OpenCoach MatchDay
- OpenCoach SquadTrack

========================================================
1. PREAMBLE
========================================================

OpenCoach is a free and open source software project created to support
football clubs, trainers, volunteers, organizers and youth sports.

This software may be used, modified and distributed under the conditions
defined in this license agreement.

The intention of this license is:
- to allow free use and further development,
- to keep the project accessible for small clubs,
- to preserve attribution to the original project and contributors,
- and to protect the identity and visibility of OpenCoach.

Because apparently humans cannot resist deleting credits after receiving
hundreds of hours of free work.

========================================================
2. PERMITTED USE
========================================================

You are allowed to:

- use the software privately or commercially,
- host the software on your own server,
- modify the source code,
- extend the functionality,
- adapt the design and layout,
- redistribute modified or unmodified copies,
- contribute improvements back to the project.

No subscription fees or royalties are required.

========================================================
3. MANDATORY ATTRIBUTION
========================================================

The following footer attribution MUST remain permanently visible
inside the software interface, administration area, exports and
all public pages where originally included:

"OpenCoach"
and
"Spfr. Haßmersheim"

including all associated hyperlinks and redirects.

The attribution/footer may:
- be visually extended,
- be repositioned reasonably,
- receive additional project or club names,
- receive styling changes.

The attribution/footer may NOT:
- be removed,
- hidden,
- visually obscured,
- replaced,
- disabled,
- disconnected from its original link target,
- manipulated through CSS, JavaScript or overlays,
- be made unreadable by color, opacity or sizing tricks.

This applies to:
- source code,
- generated PDFs,
- exports,
- screen modes,
- embedded views,
- mobile views,
- kiosk/screen displays,
- modified forks.

========================================================
4. FORBIDDEN ACTIONS
========================================================

You are NOT allowed to:

- claim the software as your original work,
- remove or alter copyright notices,
- remove mandatory attribution,
- sell the software as a closed-source proprietary product,
- sublicense the software under a more restrictive license,
- use the OpenCoach name or branding deceptively,
- redistribute versions that intentionally bypass attribution protection.

========================================================
5. DISTRIBUTION OF MODIFIED VERSIONS
========================================================

Modified versions may be distributed only if:

- this license file remains included,
- original copyright notices remain intact,
- mandatory attribution remains functional and visible,
- modifications are clearly identifiable.

Recommended example:

"Based on OpenCoach MatchDay"
or
"Modified version of OpenCoach SquadTrack"

========================================================
6. WARRANTY DISCLAIMER
========================================================

THIS SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO:

- MERCHANTABILITY,
- FITNESS FOR A PARTICULAR PURPOSE,
- SECURITY,
- AVAILABILITY,
- DATA INTEGRITY,
- OR NON-INFRINGEMENT.

The authors are not liable for:
- damages,
- data loss,
- tournament chaos,
- angry parents,
- broken schedules,
- missing attendance statistics,
- or volunteers screaming into folding tables at 22:30
  because somebody entered the wrong result.

Use at your own risk.

========================================================
7. TERMINATION
========================================================

Any violation of this license automatically terminates the rights
granted under this agreement.

Especially:
- removal of attribution,
- removal of footer links,
- hiding OpenCoach or Spfr. Haßmersheim references.

Upon violation, all usage and distribution rights immediately expire.

========================================================
8. OPEN SOURCE SPIRIT
========================================================

OpenCoach is built with the intention of helping grassroots football.

If you improve the software, consider contributing back to the project
so other clubs can benefit as well.

Turns out collaboration works better than every club suffering alone
inside twenty different Excel sheets from 2009.
