Yigcore Excel Add-in — License Terms
This document is provided in English only.
These License Terms govern the Yigcore Excel Add-in software — both the 30-day partnership trial and the free Partnership license provided during the public beta. They are separate from the site Terms of Use. The licensor's legal identity and the governing-law clause are being finalised as an EU entity is registered; see the Legal Notice.
1. Parties and definitions
"Licensor", "we", "us" means the operator of Yigcore identified in the Legal Notice. "Software" means the Yigcore Excel Add-in (Office task pane and =YIGAI functions), version 1.x. "You" means the individual or organisation that registers a trial or receives a Partnership license. "BYOK" means "bring your own key" — the LLM provider API keys you supply.
2. License grant
- Partnership license (free during the public beta): a worldwide, non-exclusive, non-transferable, non-sublicensable license to install and use the Software, version 1.x, for one named user, for the duration of the beta access period granted to you and renewable by sharing feedback.
- Trial license (30 days): a time-limited, non-exclusive, non-transferable license to evaluate the Software for the feature scope described on the plans page. The trial license expires automatically at the end of the trial period.
- The license is keyed to the Software's version 1.x major series. A future major version may require a separate license. Bug-fix and minor (1.x) updates are included.
3. Bring your own key (BYOK) and your responsibilities
The Software operates with LLM provider API keys that you supply (OpenAI, Anthropic, Gemini, Mistral, DeepSeek, a local Ollama model, and compatible endpoints). You are solely responsible for:
- Your agreement with, and all fees charged by, your LLM provider(s);
- Compliance with your provider's terms and acceptable-use policies for any content you send;
- The lawfulness of the workbook content you process and any consent required from third parties whose data it contains.
We are not a party to your relationship with any LLM provider and are not liable for provider availability, output, or charges.
4. Data handling
By default, your workbook contents and your provider API keys stay inside the Office task pane session on your device and are not transmitted to Yigcore. Registration sends only account and consent metadata (see the Privacy Policy and security documentation).
5. Restrictions
You may not, except to the extent applicable law overrides this restriction:
- Resell, rent, lease, sublicense, or redistribute the Software or your license key;
- Share a single-user license across multiple users, or circumvent license enforcement;
- Reverse-engineer, decompile, or disassemble the Software;
- Remove or alter proprietary notices.
6. Fees, taxes, and fulfilment
During the public beta the Partnership license is provided free of charge — there is no fee, no payment, and no card. License keys are delivered automatically by email when you start a trial; to extend access you share feedback as described on the plans page. Contact support if a key does not arrive within a few minutes. If paid licensing is introduced after the beta, pricing and any applicable taxes will be published here and will not apply retroactively to keys already issued.
7. No purchase during the public beta
Because the Partnership license is provided free of charge during the public beta, there is no purchase, payment, or associated statutory right of withdrawal, and no charge to refund. You may stop using the Software at any time and request deletion of your account data under the Privacy Policy. If paid licensing is introduced later, the applicable consumer-withdrawal terms will be published here before any purchase.
8. Warranty disclaimer
The Software is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement. The Software assists with finance and data work but does not replace professional judgement; you remain responsible for reviewing its output before relying on it. Mandatory statutory warranties owed to consumers under applicable law (including the legal guarantee of conformity) are not excluded.
9. Limitation of liability
To the maximum extent permitted by applicable law, our aggregate liability arising out of or relating to the Software and these License Terms is limited to the greater of the fees you paid for the license in the 12 months before the event giving rise to the claim or EUR 100. We are not liable for indirect, incidental, special, or consequential damages, or for loss of data, profit, or business.
Carve-outs. Nothing here limits liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, or for any liability that cannot be excluded under mandatory rules of the law applicable to you (including consumer-protection law).
10. Term and termination
The Partnership license is granted for the beta access period and may be renewed by sharing feedback; it is not perpetual. We may terminate the license if you materially breach these terms and do not cure the breach within 30 days of notice. On termination for breach you must stop using the Software. The trial license ends automatically at the end of the trial period.
11. Governing law and disputes
Pending registration of the Yigcore EU entity, the governing-law clause will be finalised on incorporation and published here. If you are a consumer habitually resident in the EU, this does not deprive you of the protection of the mandatory rules of the law of your habitual residence (Rome I Regulation art. 6). EU consumers may also use the European Commission's online dispute resolution platform: ec.europa.eu/consumers/odr/.
12. Changes and contact
We may update these License Terms; we will post the revised version with a new version identifier and effective date, and material changes affecting an active license will be notified by email. Your accepted version is recorded at registration. License questions: [email protected].
