End User License Agreement

1. Parties & Definitions

"StackSeek", "we", "us" or "our" refers to the operator of the StackSeek service available at stackseek.ai (the "Service"). "You" or "User" means the individual or legal entity accessing the Service. The Service is a buyer-facing AI research platform for enterprise software selection.

2. License Grant

Subject to your compliance with this Agreement, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your internal business or personal evaluation purposes. You may not resell, sublicense, scrape at scale, reverse engineer, or use the Service to train a competing AI system.

3. Accounts & Acceptable Use

You are responsible for activity under your account and for keeping credentials secure. You agree not to use the Service unlawfully, to upload harmful content, to attempt unauthorized access, or to interfere with other users.

4. AI-Generated Content & Accuracy Disclaimer

The Service uses large language models and automated research pipelines to produce vendor information, comparisons, dossiers, and recommendations. AI output can be incomplete, out of date, biased, or simply wrong ("hallucinated").

We do not guarantee that any data, answer, vendor description, capability claim, pricing, comparison, or recommendation presented by the Service is accurate, complete, current, or fit for any particular purpose. All output is provided "as is" and "as available" for informational purposes only and does not constitute professional, legal, financial, or procurement advice. You are solely responsible for independently verifying any information before relying on it for a purchasing decision or other action.

5. EU AI Act Disclosures

StackSeek is an AI-enabled service within the meaning of Regulation (EU) 2024/1689 (the "EU AI Act"). In line with the Act's transparency obligations:

• You are interacting with an AI system. Answers, dossiers, and shortlists are generated or substantially assisted by AI models.
• Intended purpose. The Service supports human buyers researching enterprise software. It is not a high-risk AI system as defined in Annex III and is not intended for use in employment decisions, credit scoring, law enforcement, critical infrastructure, or any other regulated high-risk context.
• Human oversight. The Service is designed for human-in-the-loop use. Final selection, procurement, and contracting decisions must be made by a human and not delegated to the Service.
• Known limitations. Outputs may contain factual errors, omissions, outdated pricing or product information, and unintended bias toward more frequently-cited vendors. Source coverage varies by domain.
• Synthetic content. AI-generated text is labeled or contextually identifiable as such within the product.
• Prohibited uses. You may not use the Service for any purpose prohibited under Article 5 of the EU AI Act, including social scoring, untargeted scraping of facial images, or manipulative techniques that cause harm.

6. Data Protection & GDPR

We process personal data in accordance with Regulation (EU) 2016/679 ("GDPR") and applicable national implementations. For personal data you submit or that we collect about you, StackSeek acts as the data controller, unless we have agreed otherwise in writing (e.g. an enterprise data processing agreement).

6.1 Categories of data & purposes

• Account data (email, name) — to provide and secure the Service. Legal basis: contract performance (Art. 6(1)(b)).
• Usage and prompt data (questions you ask, saved answers, stack context you provide) — to deliver, improve, and personalize the Service. Legal basis: contract performance and our legitimate interest in improving the product (Art. 6(1)(b) and 6(1)(f)).
• Technical logs (IP address, device, error data) — for security, abuse prevention, and debugging. Legal basis: legitimate interest (Art. 6(1)(f)).
• Billing data (for paid tiers) — to process payments and meet tax obligations. Legal basis: contract and legal obligation (Art. 6(1)(b) and (c)).

6.2 Your rights

Under the GDPR you have the right to access, rectify, erase, restrict, port, and object to processing of your personal data, and to withdraw consent where processing is based on consent. You also have the right to lodge a complaint with your national supervisory authority. To exercise any of these rights, contact us at privacy@stackseek.ai. We will respond within one month.

6.3 Retention

We retain personal data only as long as necessary for the purposes above, after which it is deleted or anonymized. Account data is retained for the lifetime of your account plus a limited period for legal and accounting requirements.

6.4 International transfers

Where personal data is transferred outside the European Economic Area, we rely on adequacy decisions or the European Commission's Standard Contractual Clauses, with supplementary measures where appropriate.

6.5 Automated decision-making

The Service produces AI-assisted recommendations but does not make decisions that produce legal or similarly significant effects about you within the meaning of Art. 22 GDPR. Recommendations are advisory and require human review.

6.6 Use of your inputs for model training

We do not use your private subscriber context (e.g. your stack, constraints, or private notes) to train third-party foundation models. Aggregated and de-identified usage data may be used to improve our own ranking, retrieval, and evaluation systems.

6.7 Bookmarks & aggregate audience signals

When you bookmark or highlight a vendor, offering, category, or dossier section, we store that bookmark against your account so you can find it again in your highlights workspace. Your individual bookmarks are private to you and visible only via your authenticated session.

We may share aggregated, anonymized bookmark counts with vendors and domain partners (e.g. "X buyers saved this strength"). Such aggregates are only published when the underlying data covers at least three (3) distinct buyers for the same segment, so that no individual user can be re-identified. We never share your identity, email, employer, IP address, or the full set of items you have bookmarked with any vendor or third party. You can remove a bookmark at any time from your highlights page; removal is reflected in future aggregates.

7. Vendor & Third-Party Content

The Service surfaces information about third-party vendors gathered from public sources, vendor-supplied claims, and AI synthesis. Mention of a vendor is not an endorsement. Trademarks and product names belong to their respective owners.

8. Intellectual Property

The Service, including its software, design, taxonomies, and original written content, is owned by StackSeek and protected by intellectual property laws. You retain ownership of content you submit and grant us a worldwide, non-exclusive license to host and process it for the purpose of providing the Service to you.

9. Fees

Free tier features are provided at no cost. Paid tiers are billed per the pricing page. Fees are non-refundable except where required by law.

10. Warranty Disclaimer

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY OF AI-GENERATED OUTPUT. NOTHING IN THIS SECTION LIMITS RIGHTS THAT CANNOT BE EXCLUDED UNDER MANDATORY LAW (INCLUDING EU CONSUMER LAW).

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, STACKSEEK SHALL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR PROCUREMENT DECISIONS MADE IN RELIANCE ON THE SERVICE. OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNTS YOU PAID TO US IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR EUR 100 IF YOU USE ONLY THE FREE TIER. NOTHING IN THIS AGREEMENT LIMITS LIABILITY FOR FRAUD, GROSS NEGLIGENCE, OR ANY LIABILITY THAT CANNOT BE EXCLUDED UNDER MANDATORY LAW.

12. Termination

You may stop using the Service at any time. We may suspend or terminate access for breach of this Agreement or to comply with law. Sections that by their nature should survive (IP, disclaimers, liability, governing law) survive termination.

13. Changes to this Agreement

We may update this Agreement to reflect product or legal changes. We will post the new version with an updated effective date and, where the change is material, notify you in-product or by email before it takes effect.

14. Governing Law

This Agreement is governed by the laws of the European Union member state in which StackSeek is established, without regard to conflict-of-laws principles. Mandatory consumer protections of your country of residence still apply.
