Cell AI – Terms of Service
Effective date: 20 June 2025
These Terms of Service ("Terms") are a binding agreement between you ("Customer", "you") and Hack GmbH, Am Heumarkt 4, 1030 Vienna, Austria, doing business as "Cell AI" ("Cell AI", "we", "us"). By accessing or using the Cell AI website, Excel add-in, API or any associated services (collectively, the "Services") you accept these Terms. If you disagree with any part, do not use the Services.
1. Use of Services
Cell AI is an Excel copilot that can:
- explain spreadsheet formulas
- create or modify Excel workbooks, VBA/macros or Office-Scripts automation
- generate SQL queries, charts and data-analysis insights
- draft summaries and reports
All output is generated by artificial-intelligence models and is provided "as is" without guarantee of accuracy, completeness or fitness for your particular purpose.
2. Acceptable-Use Policy
You must not use the Services to:
- violate laws or regulations;
- generate malicious code, spam or harmful automations;
- circumvent usage limits, security or rate-limiting;
- interfere with the proper functioning of the Services;
- upload personal data without a lawful basis;
- engage in any unlawful, harassing or discriminatory activity.
We may suspend or terminate access for violations.
3. Data Usage Rights
You retain ownership of spreadsheets, prompts and outputs that you upload or generate ("Customer Data"). You grant Cell AI a non-exclusive, worldwide, royalty-free licence to process Customer Data for the purpose of providing, maintaining and improving the Services. For model-improvement we use only anonymised and aggregated information.
Further details are provided in our Data-Protection Declaration.
4. Intellectual Property
Except for Customer Data, all content, software and trademarks within the Services are the property of Hack GmbH or its licensors and are protected by copyright and other laws. We grant you a limited, revocable, non-exclusive, non-transferable licence to use the Services for your internal business purposes. You may not copy, modify, distribute or create derivative works from our content without prior written consent.
5. Disclaimers
The Services and all AI-generated output are provided "as is" and "as available". Cell AI disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that output will be error-free, reliable or suitable for any use case.
6. Limitation of Liability
To the maximum extent permitted by law, Hack GmbH shall not be liable for indirect, incidental, special, consequential or exemplary damages, including lost profits, lost data or business interruption. Hack GmbH's aggregate liability arising out of these Terms will not exceed the fees you paid to Cell AI in the twelve (12) months preceding the claim.
7. Indemnification
You will defend, indemnify and hold harmless Hack GmbH, its directors, employees and agents against all claims, losses and expenses arising out of (i) your use of the Services, (ii) Customer Data, or (iii) your breach of these Terms.
8. Dispute Resolution
Any dispute shall first be subject to good-faith negotiations for 30 days. Unresolved disputes will be finally settled by arbitration under the Vienna Rules (VIAC) by one arbitrator, seat Vienna, language English. Proceedings must be brought individually; class actions are waived. Either party may seek injunctive relief in competent courts.
9. Force Majeure
Neither party is liable for delay or failure caused by events beyond reasonable control (e.g. outages, natural disasters, governmental actions).
10. Termination
We may suspend or terminate the Services at any time for breach of these Terms or if required by law. Upon termination you must cease all use of the Services; sections that by nature should survive (e.g. Intellectual Property, Disclaimers, Liability) will remain in effect.
11. Refund Policy
Refund eligibility:
Subscription fees are normally non-refundable. If persistent technical issues (solely attributable to Cell AI) cannot be resolved, we may, at our discretion, refund the current billing period. No refunds are provided more than 7 days after first use.
Cancellation:
You may cancel at any time; access to paid features remains until the end of the billing cycle.
12. Governing Law
These Terms are governed by Austrian law, excluding conflict-of-law rules. Courts in Vienna have exclusive jurisdiction for matters not subject to arbitration.
13. Eligibility
The Services are intended for users aged 18 or older (or the age of majority in your jurisdiction). If you are younger, you must obtain consent from a parent or legal guardian.
14. Changes to Terms
We may update these Terms at any time. Material changes will be announced on the website or by e-mail. Continued use after changes become effective constitutes acceptance.
