HALDE Source-Available Licence 1.0
Copyright (c) 2026 J. Philipp de Graaff, www.playsheep.de

1. Definitions
   "HALDE" means this software and its documentation, in source or binary form.
   "Derivative" means any work based on HALDE or containing a substantial part
   of it.
   "You" means the person or organisation exercising the permissions below.

2. Permission to use
   You may use HALDE for any purpose, without charge. This expressly includes
   use inside a company, an authority or any other organisation, and it
   expressly includes using HALDE as a tool while performing paid work for a
   third party, such as data recovery for a customer.

3. Permission to copy, modify and redistribute
   You may copy HALDE, modify it and redistribute the original or a Derivative,
   free of charge, provided that:
   a) this licence and the copyright and authorship notices are retained in
      full and remain visible in the source;
   b) modified files are marked as modified, stating who changed them and when;
   c) a Derivative is not presented as the original HALDE, and the name HALDE
      is not used in a way that suggests the copyright holder endorses it.

4. Restriction on sale and commercial distribution
   Without prior written permission from the copyright holder, you may not:
   a) sell HALDE or a Derivative, or licence it for a fee;
   b) distribute HALDE or a Derivative as, or as part of, a product or service
      that is offered for payment, where HALDE provides a substantial part of
      that product's or service's function or value;
   c) offer third parties paid access to HALDE or a Derivative itself as hosted,
      software-as-a-service, or managed software.

   Section 2 is not limited by this section. For the avoidance of doubt, a
   person or organisation may charge for data recovery or other professional
   services performed using HALDE, provided the customer is paying for the
   professional service or its result and not for access to HALDE itself.

   If you would like to do something this section does not allow, please ask.
   Separate commercial licences may be available by written agreement.

5. Name and marks
   This licence does not grant any right to use HALDE or any HALDE logo as a
   trademark, except for truthful identification of the original software and
   for the attribution required by this licence.

6. No warranty
   HALDE is provided "as is", without warranty of any kind, express or implied,
   including but not limited to warranties of merchantability, fitness for a
   particular purpose and non-infringement. Data recovery is inherently
   uncertain. HALDE may fail to recover data, may present incomplete results,
   and may report a file as recoverable when it is not.

7. Limitation of liability
   To the fullest extent permitted by applicable law, the copyright holder
   shall not be liable for loss of data, loss of profit, business interruption
   or other direct, indirect, incidental, special or consequential damages
   arising from the use of or inability to use HALDE.

   Nothing in this licence excludes or limits liability to the extent that such
   exclusion or limitation is prohibited by mandatory applicable law,
   including, where applicable, liability for intent, gross negligence, or
   injury to life, body or health.

8. Termination
   Your rights under this licence end automatically if you breach it. They are
   reinstated if you cure the breach within 30 days of becoming aware of it.

9. Severability and language
   If any provision is held unenforceable, the remaining provisions stay in
   force. The English text is the binding version. Any translation is provided
   for convenience only.
