Terms of Service

1. Acceptance of Terms

By accessing and using the Penumbra platform operated by Penumbra Systems, Inc. ("Penumbra," "we," "our," or "us"), you accept and agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use our platform.

2. Description of Service

Penumbra provides tools for organizing files, defining structured information with Shapes, working with knowledge graphs, and collaborating through projects, APIs, and connected assistants. AI features can extract, generate, and help organize information. AI output can be incomplete or incorrect; you are responsible for reviewing it before relying on it or applying it to your work.

3. User Accounts

• You must provide accurate and complete registration information
• You are responsible for maintaining the security of your account
• You must be at least 18 years old to use Penumbra
• One person or legal entity may maintain only one free account
• You are responsible for all activity under your account

4. Acceptable Use

You agree not to:

• Violate any laws or regulations
• Infringe on intellectual property rights
• Upload malicious code or viruses
• Attempt to gain unauthorized access to our systems
• Use the platform for illegal or harmful purposes
• Interfere with or disrupt the service
• Scrape or harvest data from the platform
• Resell or redistribute our services without permission

5. Content and Intellectual Property

Your Content: You retain all rights to content you create on Penumbra. By using our platform, you grant us a license to host, store, and process your content to provide our services.

Our Platform: Penumbra and its original content, features, and functionality are owned by us and protected by international copyright, trademark, and other intellectual property laws.

6. Payment Terms

• Any paid plan, price, billing interval, included usage, and applicable trial or discount will be shown before you purchase or agreed in a separate order. Creating a free account does not itself authorize a charge.
• Where you choose a recurring subscription, fees are billed in advance and renew at the disclosed interval until cancelled. Use the billing portal when available, or contact legal@pnbr.io for billing and cancellation requests.
• Metered features may require available credits and a project spending allowance. Applicable rates and limits govern use. Recorded model usage is not necessarily a charge: failed or cancelled AI runs release their reserved credits, and successful runs are settled under the applicable rate and reservation.
• Unless required by law or agreed otherwise, subscription fees are not refunded for partial periods or unused services. Ask us about disputed or incorrect charges.
• We reserve the right to change pricing with 30 days notice
• You are responsible for all taxes
• Failure to pay may result in service suspension

7. Service Availability

While we strive for high availability, we do not guarantee uninterrupted access. We may modify, suspend, or discontinue any part of the service at any time.

8. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. WE DISCLAIM ALL WARRANTIES INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, PENUMBRA SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES.

10. Termination

We may terminate or suspend your account for violation of these terms. You can request account deletion in Account settings or by emailing privacy@pnbr.io. Requests are verified and processed by our team; submitting a request does not immediately delete your account or data. Subscription cancellation and account deletion are separate requests. Organization content and records we need to retain are handled as described in our Privacy Policy and any applicable agreement.

11. Indemnification

You agree to indemnify, defend, and hold harmless Penumbra Systems, Inc. and its officers, directors, employees, and agents from any claims, damages, or expenses (including reasonable attorney fees) arising from your use of the platform or violation of these Terms.

12. API and Developer Terms

If you access Penumbra through our API, MCP (Model Context Protocol) integration, or developer tools, the following additional terms apply:

• API keys and OAuth tokens are confidential credentials. You are responsible for keeping them secure and must not share them publicly
• You must not exceed reasonable rate limits or use the API in a way that degrades service for other users
• Automated access must comply with these Terms and our API documentation
• We may revoke API access at any time for violation of these terms or abuse of the service
• Data accessed through the API is subject to the same privacy and security obligations as data accessed through the web interface

13. Data Processing

Our processing of personal data is governed by our Privacy Policy. For enterprise customers requiring a Data Processing Agreement (DPA), please contact us at legal@pnbr.io.

14. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of law provisions. Penumbra Systems, Inc. is a Delaware corporation.

15. Dispute Resolution

Any dispute arising from these Terms or your use of Penumbra shall be resolved through binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. Arbitration shall take place in Wilmington, Delaware.

Exceptions: Either party may seek injunctive or equitable relief in any court of competent jurisdiction to protect its intellectual property rights. Claims eligible for small claims court may be brought there instead.

Class action waiver: You agree to resolve disputes with us on an individual basis. You waive any right to participate in a class action lawsuit or class-wide arbitration.
