Terms of Service

Effective date: March 24, 2026 · Last updated: March 24, 2026

These Terms of Service (“Terms”) govern your access to and use of the services provided by LOCALIZE AI LLC (“l6e,” “l6e ai,” “we,” “us,” or “our”), including the l6e website at l6e.ai, the l6e dashboard at app.l6e.ai, the l6e API at api.l6e.ai, the l6e documentation at docs.l6e.ai, and the l6e MCP server software (collectively, the “Service”).

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Description of the Service

l6e provides budget enforcement for AI coding agents. The Service enables developers to set per-session spend limits when using AI coding assistants such as Cursor, Claude Code, and Windsurf. l6e operates as an MCP (Model Context Protocol) server that checkpoints agent operations against a budget you set, providing gate decisions (allow, reroute, or halt) based on estimated token costs.

The Service includes:

• l6e MCP Server — an open-source (MIT) locally-installed MCP server that enforces budget gates during AI coding sessions.
• l6e Cloud — optional cloud features including session history, usage dashboards, calibration from billing imports, and reconciliation of estimated costs against actual provider billing.
• l6e API — a hosted API that supports cloud sync, calibration factor retrieval, and session report storage.

1.1 Estimate-Based Enforcement

l6e budget enforcement is based on token estimates, not exact costs. The AI coding agent provides token count estimates at each checkpoint, and l6e uses these estimates — along with your personal calibration factor, if available — to approximate spend. Budget limits, remaining balance, and cost figures displayed in the Service are approximations. Actual costs from your LLM provider may differ from l6e’s estimates. l6e does not guarantee that your actual LLM spend will match the budgets you set.

Calibration improves accuracy over time as you import billing data, but calibrated estimates are still approximations.

1.2 No Proxy in Standard Mode

In standard mode, l6e does not proxy, intercept, or route your LLM API calls. The MCP server only receives the metadata that your AI coding agent passes to it at each checkpoint: token count estimates, model identifiers, tool names, and gate parameters. l6e never receives, stores, or has access to your prompts, completions, or source code in standard mode.

2. Accounts

2.1 Account Creation

To access l6e Cloud features, you must create an account by authenticating via GitHub OAuth through our identity provider (Supabase Auth). You agree to provide accurate information and to keep your account secure. You are responsible for all activity under your account.

2.2 API Keys

l6e issues API keys (prefixed sk-l6e-) that authenticate your MCP server’s communication with l6e Cloud. You are solely responsible for keeping your API keys confidential. l6e stores only a cryptographic hash of your API key — we cannot recover your key if lost. Treat API keys as secrets: do not commit them to version control, share them publicly, or embed them in client-side code.

You must notify us immediately at hello@l6e.ai if you believe your API key has been compromised. You may revoke API keys at any time from the dashboard.

2.3 Account Deletion

You may delete your account at any time from Settings in the dashboard. Account deletion permanently removes your profile, API keys, run history, billing import data, reconciliation records, and all associated data. This action is irreversible.

3. Service Tiers and Usage Limits

l6e offers multiple service tiers with different rate limits and monthly usage caps:

Your effective tier is determined by the highest-tier API key associated with your account. Tier definitions, limits, and pricing are subject to change. We will provide reasonable notice before making changes that materially reduce the capabilities available at your current tier.

4. Acceptable Use

You agree not to:

• Use the Service in violation of any applicable law or regulation.
• Attempt to gain unauthorized access to the Service, other users’ accounts, or l6e infrastructure.
• Reverse engineer, decompile, or disassemble any non-open-source portion of the Service.
• Use the Service to develop a competing product or service by systematically extracting data, calibration factors, or algorithms.
• Circumvent rate limits, usage caps, or other technical restrictions.
• Interfere with or disrupt the integrity or performance of the Service.
• Use the Service to process, store, or transmit content that infringes any third party’s intellectual property rights.
• Misrepresent your identity or affiliation when using the Service.

We reserve the right to suspend or terminate your access if we reasonably believe you have violated these Terms.

5. Community Calibration

l6e offers an optional community calibration program. When you opt in (via Settings in the dashboard), l6e contributes anonymized calibration factors — aggregate model cost multipliers — to improve calibration accuracy for all users.

Community calibration shares only aggregate multipliers. It does not share session content, cost data, task summaries, or any personally identifiable information. You may opt out at any time, and opting out takes effect immediately.

6. Billing and Payment

Certain features of the Service may require payment. If you subscribe to a paid tier:

• Billing cycle. Subscriptions are billed monthly or annually as selected at the time of purchase.
• Payment method. You authorize us to charge your designated payment method for recurring fees.
• Price changes. We may change subscription pricing with at least 30 days’ notice. Price changes take effect at the start of your next billing cycle after the notice period.
• Cancellation. You may cancel your subscription at any time. Cancellation takes effect at the end of the current billing period. No prorated refunds are provided for partial billing periods.
• Taxes. You are responsible for any applicable taxes.

Free-tier accounts are not charged and do not require a payment method.

7. Open-Source Components

The l6e MCP server (l6e-mcp) and core library (l6e) are open-source software licensed under the MIT License. Your use of these open-source components is governed by the MIT license, not these Terms, except to the extent that you use them in connection with l6e Cloud services.

These Terms govern your use of l6e Cloud, the l6e API, the dashboard at app.l6e.ai, and any other hosted services operated by LOCALIZE AI LLC.

8. Intellectual Property

8.1 l6e’s IP

The Service (excluding open-source components licensed under Apache 2.0), including its design, features, documentation, and branding, is owned by LOCALIZE AI LLC and protected by intellectual property laws. These Terms do not grant you any right to use l6e’s trademarks, logos, or branding without prior written consent.

8.2 Your Data

You retain all rights to the data you provide to the Service, including billing CSV files you upload for reconciliation and any task summaries you choose to sync. We claim no ownership over your data. Our use of your data is governed by our Privacy Policy.

9. Third-Party Services

The Service integrates with third-party services including:

• GitHub — for authentication via OAuth.
• Supabase — as our identity and database provider.
• LLM providers (e.g., Anthropic, OpenAI, Google) — l6e does not interact with your LLM provider directly; your AI coding agent handles all LLM API calls independently.

Your use of third-party services is subject to their respective terms and policies. l6e is not responsible for the availability, accuracy, or practices of any third-party service.

10. Service Availability

We strive to maintain high availability of l6e Cloud, but we do not guarantee uninterrupted or error-free operation. The Service is provided on an “as available” basis.

Local-first resilience. The l6e MCP server is designed to operate locally. If l6e Cloud is unavailable, the MCP server continues to enforce budgets using local data and cached calibration factors. Cloud sync queues reports locally and drains them when connectivity returns.

11. Disclaimer of Warranties

Without limiting the foregoing, we do not warrant that:

• Budget estimates will match your actual LLM provider costs.
• Calibration factors will be accurate for all models, providers, or usage patterns.
• The Service will prevent overspending on LLM API calls.
• The Service will be uninterrupted, timely, secure, or error-free.

You acknowledge that l6e provides cost estimates and budget enforcement as a convenience tool, and that you remain solely responsible for managing your actual LLM API spend with your providers.

12. Limitation of Liability

13. Indemnification

You agree to indemnify, defend, and hold harmless LOCALIZE AI LLC and its founders, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or related to your use of the Service, your violation of these Terms, or your violation of any applicable law or the rights of any third party.

14. Modifications to These Terms

We may modify these Terms at any time by posting the revised version on this page and updating the “Last updated” date. It is your responsibility to review the Terms periodically. Your continued use of the Service after any modifications constitutes acceptance of the updated Terms. If you do not agree to the modified Terms, your sole remedy is to stop using the Service and delete your account.

15. Termination

15.1 By You

You may stop using the Service at any time. You may delete your account as described in Section 2.3.

15.2 By l6e

We may suspend or terminate your access to the Service at any time, with or without cause, with or without notice. We are under no obligation to provide a reason for termination or to allow continued access during any notice period.

15.3 Effect of Termination

Upon termination, your right to access l6e Cloud ceases immediately. Sections 8, 11, 12, 13, 14, and 16 survive termination.

16. General

16.1 Governing Law

These Terms are governed by the laws of the State of Michigan, United States, without regard to its conflict of laws provisions.

16.2 Dispute Resolution

Any dispute arising out of or relating to these Terms or the Service shall be resolved by binding arbitration under the rules of the American Arbitration Association. The arbitration shall take place in the State of Michigan, or remotely, at l6e’s sole discretion. The arbitrator’s decision shall be final and binding.

If for any reason a claim proceeds in court rather than arbitration, you irrevocably consent to the exclusive jurisdiction and venue of the state and federal courts located in Michigan, and you waive any objection to such jurisdiction or venue.

16.3 Class Action Waiver

YOU AND l6e AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. Unless both you and l6e agree otherwise in writing, the arbitrator may not consolidate more than one person’s claims and may not preside over any form of a representative or class proceeding.

16.4 Entire Agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and LOCALIZE AI LLC regarding the Service.

16.5 Severability

If any provision of these Terms is held unenforceable, the remaining provisions continue in full force and effect.

16.6 No Waiver

Our failure to enforce any right or provision of these Terms does not constitute a waiver of that right or provision.

16.7 Assignment

You may not assign or transfer these Terms without our prior written consent. We may assign these Terms without restriction.
