Version 2026-11-08

These terms cover the software in the package only. They do not cover the hosted service that we run (the API); the SaaS terms apply to that.

These terms apply to the package ocr-software-<version>-linux-amd64 (the "Package") that Helm & Nagel GmbH, Rosenweg 5, 35614 Aßlar, Germany ("we") offers for download on ocr-software.com. By unpacking or installing the Package, you ("you") accept these terms.

1. What you get

A simple, non-transferable, non-exclusive right to install and run the Package on your own servers, free of charge and without a time limit, but only for the uses in section 2, as long as you comply with these terms.

2. Permitted use: private and test

These terms permit exactly two kinds of use:

  1. Private use: you use the Package as a private person for purposes that are neither commercial nor self-employed professional (section 13 of the German Civil Code).
  2. Test: you are a business (section 14 of the German Civil Code) and run the Package in a test environment to find out whether it fits your purpose: test pages, measurements, comparisons, integration tests. A test environment processes no documents that your business runs on (customer documents, everyday invoices, operational files) and no third-party documents on behalf of others. It is not part of a process that you or others rely on in daily business.

Any other use is not permitted, in particular productive use in a company, an authority or any other organisation. We permit it in a contract with us; a request to info@ocr-software.com is enough to start one. A test does not turn into productive use by itself: once documents are processed that your business runs on, you need the contract.

Also not permitted:

  1. running the Package as a service for third parties (OCR as a service, API or product for customers, hosting for third parties);
  2. passing on, selling, renting, sublicensing or offering the Package or parts of it for download;
  3. building the Package into a product that you distribute;
  4. removing notices of authorship, licence or origin.

Reverse engineering and modification are allowed only where the law permits them in a way that cannot be waived (sections 69d, 69e of the German Copyright Act).

3. Support and maintenance

The Package comes without support, without maintenance and without any promise of updates. A claim to fixes, response times or availability arises only from a written contract with us. A request to info@ocr-software.com is enough to start one.

4. Third-party software, models

The Package contains Go libraries under their own licences (file NOTICE). You fetch the Python packages and the model weights yourself with ocr-fetch-models.sh; the command shows source, licence and size first. Their licences remain untouched and, for the component concerned, take precedence over these terms. You obtain the NVIDIA driver, CUDA parts and poppler yourself; they are not part of the Package.

5. Liability

Because the Package is provided free of charge, we are liable only for intent and gross negligence, for injury to life, body or health, and under the Product Liability Act; fraudulently concealed defects remain unaffected. We do not promise that results are error-free. You check results yourself before important decisions. You back up your own data.

6. Data

The Package is set up so that it makes no connection to the outside by itself; only the command ocr-fetch-models.sh downloads packages and models, at your request. We receive no documents and no usage data. You are the controller of your documents.

7. End

The right ends without notice if you breach these terms, including by a use that section 2 does not permit. We may end the licence for future versions with 3 months' notice; for versions already downloaded it remains as long as you comply with the terms. When it ends, you delete the Package.

8. Final provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods; towards consumers it applies only as far as mandatory consumer protection rules of their country of residence do not conflict with it. The place of jurisdiction is Wetzlar, as far as permitted. If a provision is invalid, the rest remains valid. These terms exist in German and English; if the two differ, the German version governs.
