FeedForge Terms of Service

Last updated: July 30, 2026

1. The Service

FeedForge is a speeds & feeds calculation aid. Based on the material, tool diameter, flute count and similar values you enter, it calculates RPM, feed rate, chip load, tap drill diameters, bolt circle coordinates and power estimates. Results are conservative starting ranges based on an open dataset and are for reference only. The basic calculators and a subset of materials are available at no charge; the one-time unlock (cncfeeds_pro_lifetime) enables all materials, bolt circle, power estimates, unlimited saved jobs and CSV export.

2. Acceptable Use

Use the App as a personal calculation aid. Deciding actual cutting conditions and verifying safety is entirely your responsibility; always validate values against your own tool and machine before critical operations.

3. Purchases and Refunds

The Pro unlock is a one-time purchase (product ID cncfeeds_pro_lifetime) processed under the policies of the store where you bought it (Apple App Store or Google Play). Refunds follow the refund policy of that store.

4. Limitation of Liability

The App is provided "as is". Calculated values are reference starting points and must be verified by you before machining. The App is not liable for calculation errors, tool breakage, material loss or machining accidents.

5. Intellectual Property and Open Source

Design, code and content rights belong to the developer (hedvion). Unauthorized copying, distribution or decompilation is prohibited. Material data comes from the MIT-licensed CNC-ToolHub open dataset; the notice is shown in the in-app open source licenses screen.

6. Governing Law

These terms are governed by the laws of the Republic of Korea.
