Terms of Use
Effective April 29, 2026
These terms apply to your use of the parallelogram.dev website and the open-source parallelogram CLI. By using either, you agree to what follows.
The software is open source
The CLI is licensed under the Apache License, Version 2.0. The license text is the authoritative document governing your rights to use, modify, and redistribute the software. These terms do not override or expand on the license — they exist alongside it. You can read the full license in the repository at github.com/Thatayotlhe04/Parallelogram.
No warranty
Parallelogram is provided "as is", without warranty of any kind, express or implied. We make every effort to make the validator correct, but no validator can guarantee that any particular dataset will produce a successful training run, or that any model trained on parallelogram-validated data will perform as you hope. The promise on the home page — "if it exits 0, your run won't fail because of data" — refers specifically to the failure modes the v0.1 rule set covers (schema, role sequence, empty content, context window, exact duplicates, encoding artifacts), as documented. It is not a warranty against all possible training failures, only the specific ones the validator checks for.
No liability
To the maximum extent permitted by law, the authors and contributors of Parallelogram are not liable for any damages, including lost training runs, corrupted models, wasted compute, lost revenue, or any other direct, indirect, incidental, or consequential damages arising from your use of the software or this website.
Acceptable use of the website
Don't try to break parallelogram.dev. Don't scrape it abusively, attempt to attack the hosting infrastructure, or use it to distribute malware. The site is a static page; there is very little to abuse, but please don't try.
Third-party trademarks
The names and marks of other projects mentioned on this site — including Axolotl, Unsloth, TRL, Hugging Face, OpenAI, and GitHub Actions — belong to their respective owners. Their appearance on this page is a factual statement of format compatibility under nominative fair use, not an endorsement, partnership, or affiliation. If a rightsholder objects to a particular mention, we will remove or modify it on request.
Changes
We may update these terms over time. Material changes will be reflected by an updated effective date at the top of this page. Continued use after a change means you accept the new terms.
Governing law
These terms are governed by the laws of South Africa, without regard to its conflict-of-laws principles. Any dispute that cannot be resolved informally will be brought in the courts of South Africa.
