To provide the service, you grant us a non-exclusive, worldwide, royalty-free license, limited strictly to what is necessary for service operation, to:

• Store, index, and vectorize your User Content

• Retrieve and return relevant content when you actively query

• Generate personal derivatives visible only to you (such as Soul Profile and growth reports)

We will not use your User Content to train general-purpose AI models, not share it with other users, and not use it for advertising. When you close your account, your User Content will be permanently deleted.

All intellectual property rights in the KnowMine service itself (including software, interface design, trademarks, and documentation) belong to KnowMine and are protected by applicable law.

This Agreement does not grant you any ownership of, or license to, KnowMine's intellectual property beyond what is necessary to use the service. Without written authorization, you may not copy, modify, distribute, or create derivative works of any part of KnowMine.

KnowMine integrates with or depends on the following third-party services, each subject to its own terms:

• Neon: managed PostgreSQL database and pgvector storage

• Vercel: application hosting

• DashScope / OpenAI-compatible services: AI generation and embeddings depending on the specific feature and configuration

• Tencent Cloud / DashScope: voice transcription when configured

• Object-storage providers: storage for voice and document files you choose to upload

• Resend: transactional email delivery

• Creem: subscription and payment processing

We select third-party providers carefully but cannot guarantee their availability or performance.

The service is provided "as is". To the maximum extent permitted by law, we disclaim all express or implied warranties, including warranties of merchantability, fitness for a particular purpose, non-infringement, uninterrupted availability, and error-free operation.

In particular:

• AI-generated Soul Profiles and insight reports are for reference only and do not constitute advice of any kind

• Accuracy of semantic search results depends on many factors; do not rely on them as a sole basis for decisions

• We do not guarantee that the service will be uninterrupted or bug-free, but we will make reasonable efforts to maintain quality

To the maximum extent permitted by law, KnowMine shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, goodwill, or business interruption.

If KnowMine is found liable despite the foregoing, cumulative liability shall not exceed the total fees you paid to KnowMine in the preceding 12 months or USD $100, whichever is lower.

You may cancel your subscription or delete your account at any time via the web interface. Upon deletion, all your User Content will be permanently removed within 30 days.

We may suspend or terminate your account if:

• You violate these Terms

• Your account has been inactive for more than 24 months with outstanding fees

• Required by law or a lawful government request

• The service is discontinued entirely

Termination does not relieve you of payment obligations already incurred.

We may amend these Terms from time to time. Material changes will be announced by email or website notice at least 14 days in advance. Continued use after the notice period constitutes acceptance of the revised Terms. If you disagree, please stop using the service and close your account.

This Agreement is governed by the laws of the jurisdiction in which the service provider is located. Any dispute arising from this Agreement or the service shall first be resolved through good-faith negotiation. If negotiation fails, disputes shall be submitted to a competent court or arbitration body in the service provider's jurisdiction.
