Terms of Service

1. Agreement to Terms

By accessing or using Kertas ("Service", "Platform"), you agree to be bound by these Terms of Service ("Terms"). If you disagree with any part of these terms, you may not access the Service.

Kertas is an agent execution platform operated by Kertas ("Company", "we", "us", or "our").

2. Description of Service

Kertas provides the following services:

• Skill Distillation: Capture organizational know-how into standard SKILL.md packages and deploy them to agent workspaces
• Agent Execution Runtime: Governed ReAct loop with namespaced tools (fs, knowledge, agent, control, git, shell, mcp) per workspace
• Approval Per Action: Operators review, edit, or reject every non-safe tool call before execution
• Decision Trace Learning: Every cycle and human edit is captured so the underlying skill compounds with use
• Wiki-Pattern Workspaces: Per-execution virtual filesystem with raw inputs, knowledge, and artifacts isolated by organization
• Sandboxed Tooling: @cloudflare/sandbox-backed `git.*` and `shell.exec` for code-aware skills

3. Account Registration & Responsibilities

3.1 Account Creation

• You must provide accurate, current, and complete information
• You must be at least 18 years old (or 16 in the EU with parental consent)
• You are responsible for maintaining account security
• One person or legal entity per account
• You must not share account credentials

3.2 Organization Accounts

Organization accounts allow multiple users to collaborate. The organization owner is responsible for managing members, permissions, and ensuring compliance with these Terms.

3.3 Account Termination

We reserve the right to suspend or terminate accounts that violate these Terms, engage in fraudulent activity, or abuse the Service.

4. Credit System & Billing

4.1 Credit-Based Pricing

Kertas operates on a credit-based system. Credits are consumed when using AI features:

• Agent Cycle: Variable based on the model + token consumption of each ReAct cycle
• Skill Upload + Tier Loading: Charged on first deployment when reference material is parsed and embedded
• Sandbox Container: Per-second runtime cost while the @cloudflare/sandbox container is warm for `git.*` / `shell.exec` tools

4.2 Credit Packages

Credits are purchased in packages ranging from 100 credits ($8) to 10,000 credits ($500). Volume discounts apply. Custom enterprise pricing available.

4.3 No Refunds

Credits are non-refundable once purchased. Credits do not expire but may be forfeited if your account is terminated for violations.

4.4 Payment Processing

Payments are processed securely through Stripe. You agree to provide accurate payment information and authorize us to charge your payment method.

4.5 Price Changes

We reserve the right to modify credit costs and pricing with 30 days' notice. Changes do not affect previously purchased credits.

5. Acceptable Use Policy

You agree NOT to:

• Upload malicious content, viruses, or malware
• Process illegal, defamatory, or infringing content
• Attempt to circumvent credit systems or abuse free trials
• Reverse engineer, decompile, or extract models/algorithms
• Resell or redistribute the Service without authorization
• Use the Service for automated scraping or data mining beyond intended use
• Impersonate others or provide false information

6. Intellectual Property Rights

6.1 Your Content

You retain all ownership rights to documents, data, and content you upload ("Your Content"). You grant us a limited license to process Your Content solely to provide the Service.

6.2 Platform Rights

The Service, including software, algorithms, UI/UX, branding, and documentation, is owned by Kertas and protected by copyright, trademark, and other intellectual property laws.

6.3 AI-Generated Content

Content generated by an agent execution (artifacts, knowledge entries, summaries) is provided "as-is". You are responsible for reviewing each proposed tool call via the approval flow and for verifying the final artifacts before use.

7. AI Processing & Limitations

7.1 AI Accuracy

AI models may produce inaccurate, incomplete, or biased outputs. We do not guarantee the accuracy of AI-generated content. You should independently verify critical information.

7.2 Decision-Trace Learning

Every approval, rejection, and inline edit you make is recorded as part of the execution trace and may be used to improve the underlying skill within your organization. We do not use your workspace data to train shared models without explicit opt-in consent.

7.3 Third-Party AI Services

We use third-party AI providers (OpenRouter, Tavily). These providers have their own terms and privacy policies. We are not responsible for their actions or errors.

8. Data Usage & Training

Important: We do not use Your Content to train AI models or improve third-party AI services without explicit opt-in consent. Your documents and conversations remain private.

We may use aggregated, anonymized usage statistics to improve the Platform (e.g., performance metrics, feature adoption rates).
