Last updated: September 2026
1. What HertzKit is
HertzKit is a set of free web tools for musicians and audio creators. No registration is required, and every tool runs directly in your browser.
2. Permitted use
You may use the tools for personal, educational or professional purposes, free of charge. You may not attempt to interfere with the site's operation, deliberately overload it, or copy the code for resale.
3. No warranties
The tools are provided "as is". We do not guarantee absolute accuracy in measurements (e.g. pitch or tempo detection), uninterrupted availability, or that the site is free of errors. Do not rely solely on HertzKit for uses where an error would have serious consequences.
4. Third-party content
The site displays advertising served by third-party networks (such as Google AdSense), which may use their own cookies. See the cookie policy.
5. Ownership
HertzKit's code, design and text belong to its creators, except for third-party libraries used under their own licenses.
