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

1. Description of service

The Site provides free, browser-based calculators for gear ratios, automotive transmission and differential speed estimates, and bicycle gearing figures, along with related reference charts and educational content. The Service is provided for informational and estimation purposes only.

2. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any applicable local, state, national, or international law;
• Attempt to interfere with, disrupt, or gain unauthorized access to the Site, its servers, or any connected network;

• Use automated means (bots, scripts) to place an abnormal load on the Site's infrastructure;
• Misrepresent your identity or affiliation when contacting us.

3. No warranty; accuracy disclaimer

The calculators on this Site are provided for reference and estimation only. While we make reasonable efforts to implement standard, correct gear ratio, RPM-to-speed, and gear-inch formulas, we make no warranty, express or implied, as to the accuracy, completeness, or reliability of any result produced by the Service. Real-world figures can be affected by factors the calculators do not model, including tire wear and load, wheel slip, drivetrain friction, measurement tolerances, and manufacturer variance.

You should independently verify any figure produced by this Site — especially before making automotive modifications (gearing, differential, or tire changes), performance or racing decisions, or any engineering, mechanical, or safety-critical decision. Do not rely on this Service as a substitute for professional mechanical, engineering, or automotive advice. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
