RailCall Studio — Build programs, automate workflows & run AI agents, locally

1. Agreement to Terms

By accessing or using RailCall (the "Service"), you agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree, do not use the Service.

2. Description of Service

RailCall is a local-first AI automation platform that enables:

Governed execution: Dry-run previews, human approval gates, and cryptographic receipts for all irreversible actions
BYOK architecture: Your API keys stored locally, never transmitted to AiTrade
Connected-service actions (v1): Direct flows from your machine to providers you choose (Slack, Stripe, GitHub, etc.) without RailCall as intermediary
MCP integration: Local connections to AI assistants like Claude Desktop
Cryptographic verification: Ed25519-signed receipts for offline audit

3. License & Restrictions

Grant

Subject to these Terms, AiTrade grants you a limited, non-exclusive, non-transferable license to use RailCall for your internal business or personal purposes.

Restrictions

You may not:

Reverse engineer, decompile, or disassemble the Service (except where prohibited by law)
Remove or modify proprietary notices
Use the Service to violate laws or infringe third-party rights
Resell, sublicense, or transfer your account without written consent
Use the Service to build a competing product

4. Accounts & Security

You are responsible for:

Maintaining the confidentiality of your account credentials
All activity under your account
Notifying us immediately of unauthorized access
Securing your local key vault (0600 permissions recommended)

AiTrade is not liable for losses due to compromised credentials.

5. BYOK & Connected Services (v1 Architecture)

Your Responsibility

When you provide API keys for connected services (Slack, Stripe, GitHub, etc.):

You retain ownership and control of those keys
Keys are stored locally and never transmitted to AiTrade
You are responsible for key security, rotation, and compliance with each provider's terms
RailCall v1 sends approved actions directly from your machine to the provider — AiTrade is not a party to that transaction

Data Controller Role

For connected-service action content: You are the data controller. The provider (Slack, Stripe, etc.) is your processor or independent controller per your arrangement. AiTrade is neither — that data never reaches us.

Third-Party Terms

Each connected service is governed by its own terms and privacy policy. You agree to comply with those terms. AiTrade makes no warranties about third-party services.

6. MCP Integration

RailCall v1 enables local MCP (Model Context Protocol) connections to AI assistants like Claude Desktop:

All MCP sessions are loopback/stdio — no network egress to AiTrade
The MCP host (e.g., Claude Desktop) sees what you type into it, per its own terms
RailCall governs the execution with dry-run, approval, and receipts
You are responsible for compliance with the MCP host's terms and privacy policy

7. Payment & Billing

Pricing

RailCall offers free and paid plans. Current pricing is available at railcall.ai/pricing. Paid plans are billed per seat on a recurring monthly subscription ($20 per seat / month). Local execution is not metered.

Seat Validation

Paid seats periodically validate the active seat via a blind ping — only SHA-256(key) + nonce is transmitted, never an action name. No per-action counts or business data are transmitted, and validation is decoupled from any individual run. Billing is per seat, not per run. The free single-seat tier sends no validation ping.

Refunds

Refunds are issued at AiTrade's discretion. Contact support with your request.

Late Payment & Suspension

Failure to pay may result in account suspension or termination. You remain liable for unpaid fees.

8. Acceptable Use

You agree not to use RailCall for:

Illegal activities or fraud
Spam, phishing, or malicious code distribution
Harassment, hate speech, or violating others' rights
Unauthorized access to systems or data
Activities prohibited by connected-service providers

See our Acceptable Use Policy for details. Violation may result in immediate termination.

9. Intellectual Property

AiTrade IP: RailCall software, documentation, trademarks, and related IP are owned by AiTrade LLC. These Terms do not transfer ownership.

Your IP: You retain ownership of your code, data, and content. RailCall's local-first architecture means your content stays on your machine unless you explicitly transmit it (e.g., via hosted compose).

Feedback: If you provide feedback or suggestions, AiTrade may use them without obligation or compensation.

10. Disclaimers

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND. AiTrade disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

RailCall does not guarantee: (a) uninterrupted or error-free operation, (b) that the Service will meet your requirements, (c) results obtained from use, or (d) third-party service availability.

No regulatory exemption claim. RailCall's local-first architecture reduces data transmission surface, but does not declare you SOC2, HIPAA, or GDPR compliant. Your regulatory posture remains yours to determine.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

AiTrade and its affiliates, officers, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits, data loss, or business interruption, arising from your use or inability to use the Service.

TOTAL LIABILITY CAP: AiTrade's total liability for any claim shall not exceed the fees you paid in the 12 months preceding the claim (or $100 if no fees were paid).

Connected-service actions: AiTrade is not liable for damages arising from actions you approve to connected services (Slack, Stripe, etc.). You direct those flows; the provider is your counterparty.

Some jurisdictions do not allow liability exclusions. If yours does not, these limitations may not apply.

12. Indemnification

You agree to indemnify and hold harmless AiTrade from claims, damages, and expenses (including legal fees) arising from: (a) your use of the Service, (b) your violation of these Terms, (c) your violation of third-party rights, or (d) content you transmit via RailCall.

13. Termination

By You: You may terminate your account at any time via settings or by contacting support.

By AiTrade: We may suspend or terminate your account immediately for: (a) breach of these Terms, (b) non-payment, (c) illegal activity, or (d) risk to the Service or other users.

Effect: Upon termination, your license ends, and you must cease using the Service. AiTrade may delete your account data per our retention policy. Local data (keys, receipts) on your machine is unaffected.

14. Modifications

AiTrade may modify these Terms or the Service at any time. Material changes will be announced via email or in-product notice at least 30 days in advance. Continued use after changes constitutes acceptance. If you disagree, terminate your account before the effective date.

15. Governing Law & Dispute Resolution

Governing Law: These Terms are governed by the laws of the State of Florida, USA, without regard to conflict-of-law principles.

Arbitration: Any dispute shall be resolved by binding arbitration under the American Arbitration Association (AAA) rules, conducted in Florida. You waive the right to a jury trial or class action.

Exceptions: Either party may seek injunctive relief in court for IP infringement or breach of confidentiality.

16. General

• Entire Agreement: These Terms, Privacy Policy, and Acceptable Use Policy constitute the entire agreement.
• Severability: If any provision is unenforceable, the rest remains in effect.
• No Waiver: Failure to enforce a right does not waive it.
• Assignment: You may not assign these Terms without consent. AiTrade may assign freely.
• Force Majeure: AiTrade is not liable for delays due to events beyond reasonable control.
