Terms of Service

To access paid features, you must create an account on our Website by providing a valid email address and creating a password. You agree to provide accurate, current, and complete information during registration and to update such information to keep it accurate and current.

You are responsible for maintaining the confidentiality of your account credentials, including your password and license file. You agree to notify us immediately of any unauthorized use of your account or any other breach of security. We are not liable for any loss or damage arising from your failure to protect your account credentials.

Each individual or entity may maintain one account. Creating multiple accounts to circumvent free-tier limits, trial restrictions, or other usage limitations is a violation of these Terms and grounds for immediate termination.

Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the Application on a single Windows computer for your personal or internal business purposes, in accordance with your subscription tier.

Your license is bound to a single computer identified by its Machine ID (Windows Machine GUID). The License File issued to you is valid only on the machine for which it was generated. You may not transfer your License File to another machine without first requesting a license transfer through your account dashboard or by contacting support.

The Application validates your License File locally using ECDSA digital signature verification. The Application checks the signature integrity, machine binding, and expiration date each time it is launched. Tampering with, forging, or modifying a License File is a material breach of these Terms.

Your license permits use by a single individual or, for business licenses, by employees of a single business location. Each technician workstation requires its own license. Volume licensing arrangements may be available upon request.

The Application is distributed in two editions:

Feature availability is determined by your active subscription tier. The specific features included in each tier are described on our Pricing page. We reserve the right to modify the features included in each tier with reasonable notice. Changes will not reduce functionality during an active Subscription Period.

The Free tier provides limited access to the Application at no cost. Free-tier usage is subject to the following limits, which may be adjusted at our discretion:

• Up to 2 vehicle makes
• Up to 2 vehicle models
• Up to 5 Special Function executions

Free-tier limits are tracked locally on your device. Circumventing these limits through any means (including but not limited to modifying configuration files, reinstalling the Application, or manipulating system settings) constitutes a breach of these Terms.

If a Developer-tier license is activated on the Standard Edition, it will be automatically clamped to the Professional tier. To access Developer-tier features, you must use the Developer Edition.

Paid subscriptions are billed at the rates displayed on our Pricing page at the time of purchase. All prices are in US Dollars (USD) unless otherwise stated. Applicable taxes may be added to the displayed price based on your location.

All payments are processed by Razorpay Software Private Limited, a PCI DSS Level 1 certified payment processor. We accept major credit and debit cards (Visa, Mastercard, American Express), UPI, net banking, and popular wallets. We do not store or have access to your full payment card details.

Subscriptions are billed annually. Your subscription automatically renews at the end of each Subscription Period unless you cancel before the renewal date. We will send a reminder email before renewal.

You may cancel your subscription at any time through your account dashboard or your account dashboard. Upon cancellation:

• Your access continues at your current tier until the end of the current Subscription Period.
• No further charges will be made after the current period ends.
• After the Subscription Period expires, the Application reverts to Free-tier functionality.
• Your locally stored data (sessions, vehicle profiles, configurations) remains intact and accessible regardless of subscription status.

All subscription fees are non-refundable except where required by applicable law. If you experience a technical issue that prevents you from using the Services, contact us within 14 days of your purchase and we will work to resolve the issue or, at our discretion, issue a refund.

We may change subscription prices with at least 30 days' written notice. Price changes take effect at the start of your next Subscription Period. If you do not agree with a price change, you may cancel your subscription before the new price takes effect.

• Copy, modify, adapt, translate, reverse engineer, decompile, disassemble, or create derivative works based on the Application or any part thereof.
• Remove, alter, or obscure any copyright, trademark, or other proprietary notices from the Application.
• Distribute, sublicense, lease, rent, loan, or otherwise transfer the Application or your License File to any third party.
• Use the Application on more machines than your license permits.
• Attempt to bypass, disable, or circumvent any license validation, machine binding, feature gating, trial period enforcement, or usage limit mechanism.
• Forge, tamper with, or fabricate License Files or any authentication credentials.
• Extract, capture, log, or record the proprietary diagnostic command sequences delivered through the carpm API and executed via the protected command runner. These commands are our trade secrets and intellectual property.

• Access or use the carpm API outside of the Application or in any manner not expressly authorized by these Terms.
• Scrape, crawl, or use automated means to access the Website or carpm API beyond the Application's normal functionality.
• Interfere with, disrupt, or place an unreasonable load on the Services or the servers and networks connected to the Services.
• Use the Services to develop a competing product or service.
• Resell, redistribute, or commercially exploit access to the carpm API or any data obtained through it without our prior written consent.

• Use the Application to diagnose or modify vehicles you do not own or do not have explicit authorization to service.
• Use the Application to tamper with emissions control systems, odometer readings, safety systems, or any vehicle component in violation of applicable law.
• Use diagnostic data obtained through the Application for fraudulent purposes, including but not limited to misrepresenting vehicle condition in sales transactions.
• Execute diagnostic procedures (Special Functions, code clearing, module resets) on vehicles while they are in motion or in conditions that could endanger persons or property.

The Application, Website, carpm API, and all related content including but not limited to software code, algorithms, user interfaces, designs, graphics, logos, trademarks, diagnostic databases, DTC descriptions, PID definitions, manufacturer-specific command sequences, special function procedures, and documentation are owned by CaRPM or our licensors and are protected by copyright, trademark, trade secret, and other intellectual property laws.

The manufacturer-specific diagnostic commands, special function procedures, and proprietary PID definitions delivered through the carpm API constitute our trade secrets and confidential information. These are executed through a protected command runner that intentionally prevents display of raw hex commands in the Application's terminal or logs. You acknowledge that these sequences are proprietary and agree not to attempt to intercept, capture, reconstruct, or derive them by any means, including but not limited to memory inspection, network traffic analysis, serial port monitoring, or modification of the Application.

You retain ownership of all content you create using the Application, including but not limited to custom PID definitions, diagnostic scripts, technician notes, vehicle profiles, customer data, and exported reports. We claim no ownership rights over your content.

If you provide us with feedback, suggestions, or ideas regarding the Services, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use, modify, and incorporate such feedback into the Services without any obligation to you.

Certain features of the Application require connectivity to our carpm API servers, including but not limited to: enriched DTC descriptions with causes, symptoms, and solutions; manufacturer-specific diagnostic commands; Mode 21/22 proprietary PID definitions; Special Functions procedures; and vehicle registration for model-specific features.

When you use API-dependent features, the Application automatically transmits vehicle diagnostic data to our servers as described in our Privacy Policy. By using these features, you consent to this data transmission. Core features (connection, terminal, command sets, DTC reading, graphing, and data logging) operate entirely offline.

We strive to maintain high availability of the carpm API but do not guarantee uninterrupted access. API-dependent features may be temporarily unavailable due to maintenance, updates, network issues, or other factors. The Application caches API responses locally and queues failed requests for automatic retry to minimize disruption.

We may implement rate limiting on API requests to ensure fair usage and service stability. The Application is designed to operate within these limits under normal use. Excessive or abusive API usage may result in temporary or permanent access restrictions.

You retain ownership of Vehicle Data that you collect using the Application. You grant us a non-exclusive, worldwide, royalty-free license to use, process, store, and transmit your Vehicle Data solely for the purpose of providing the Services to you, including delivering enriched diagnostic information, manufacturer-specific features, and improving our diagnostic database.

We may aggregate and de-identify Vehicle Data collected through the Services to create statistical datasets that do not identify you or any specific vehicle. We own all rights to such aggregated, de-identified data and may use it for any lawful purpose, including improving our products, conducting research, and creating industry reports.

Customer and vehicle profile data (names, phone numbers, service notes) that you enter into the Application is stored locally on your computer and is your sole responsibility. We do not access, collect, or process this data. You are responsible for complying with all applicable data protection and privacy laws regarding the personal information of your customers that you store in the Application.

The Application requires Windows 10 or Windows 11 (64-bit). An ELM327-compatible OBD-II scanner (Bluetooth, USB, or WiFi) is required for vehicle connectivity. An internet connection is required for API-dependent features, account management, and license activation.

While we strive for broad compatibility, we do not guarantee that the Application will work with every ELM327-compatible scanner, every vehicle, or every Windows configuration. Vehicle support for specific diagnostic features depends on the vehicle's OBD-II implementation, which varies by manufacturer, model, year, and market.

We may perform scheduled or emergency maintenance on the Website and carpm API that may temporarily affect availability. We will endeavor to provide advance notice of planned maintenance when possible.

We may release updates to the Application that include bug fixes, performance improvements, new features, or security patches. Updates may be required to continue using certain Services. We recommend always using the latest version of the Application.

We reserve the right to modify, suspend, or discontinue any part of the Services at any time, with or without notice. We will provide reasonable notice before discontinuing a material feature that is part of your paid subscription. If we discontinue a material feature during your active Subscription Period and no reasonable substitute is provided, you may be eligible for a prorated refund for the remaining period.

We continuously update our diagnostic databases, DTC descriptions, manufacturer-specific commands, and special function procedures through the carpm API. These updates are delivered automatically and do not require an Application update. The availability and accuracy of manufacturer-specific features depend on our ongoing database development and may change over time.

You may stop using the Services and cancel your subscription at any time. To delete your account, contact us at the email address listed in Section 25.

We may suspend or terminate your access to the Services, in whole or in part, immediately and without prior notice if:

• You breach any provision of these Terms.
• You engage in fraudulent, abusive, or illegal activity in connection with the Services.
• You attempt to circumvent license validation, trial enforcement, feature gating, or usage limits.
• You attempt to extract, capture, or reverse-engineer protected diagnostic command sequences.
• Your payment fails and is not resolved within a reasonable grace period.
• Continued provision of the Services to you would violate applicable law.

Upon termination:

• Your license to use the Application is revoked, and your License File becomes invalid.
• You must cease all use of the Application and delete all copies from your computer.
• Your access to the carpm API and API-dependent features is immediately terminated.
• Locally stored data (sessions, profiles, exports) remains on your computer and is yours to keep or delete.
• Sections of these Terms that by their nature should survive termination (including but not limited to Intellectual Property, Disclaimers, Limitation of Liability, and Indemnification) shall continue in effect.

These Terms shall be governed by and construed in accordance with the laws of India, without regard to its conflict of law provisions.

Any dispute arising out of or in connection with these Terms or the Services shall first be attempted to be resolved through good-faith negotiation. If the dispute cannot be resolved through negotiation within 30 days, either party may pursue resolution through the courts of competent jurisdiction.

To the maximum extent permitted by applicable law, you agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action.
