Terms of Service

By using BPM Key Finder you agree to the following terms. They are intentionally short on formalities and clear on the points that matter: what the service is, what you may do with it, how accurate it is, and where responsibility begins and ends.

1. The service

BPM Key Finder provides free browser-based tools for music analysis and tempo arithmetic: a combined BPM and key finder, dedicated BPM, key and tempo detector pages, a tap tempo tool, an online metronome and a BPM calculator. All tools run in your browser; there is no upload, no processing on our servers and no account system. The service may be used without registration and is offered worldwide, subject to the language versions available.

2. Acceptable use

The tools are provided for lawful personal and professional use. You agree not to:

• attempt to disrupt, overload or reverse the service infrastructure;
• circumvent technical protections or access controls;
• scrape or mirror the site in a way that degrades it for other visitors;
• use the tools in violation of any law applicable to you.

We may restrict access that violates these terms. Because the tools are stateless and anonymous, there are no user accounts to suspend — restrictions, if ever needed, apply at the technical level.

3. Accuracy of results

BPM detection, key detection and tempo classification are automated signal-analysis estimates. They are typically accurate for music with a steady beat and clear tonality, but they can be wrong — especially on live recordings, heavily processed material, sparse intros, atonal pieces or spoken word. Confidence indicators and alternative readings (half-time, double-time) are shown precisely so you can judge each result.

The results are informational. Before relying on a value in a commercial release, a broadcast, a performance or any high-stakes setting, verify it independently — for example by counting beats against a stopwatch with the BPM calculator, or by checking the key on an instrument. The tools assist trained ears; they do not replace them.

4. Your content

You retain all rights to the audio you analyze. Files are processed on your device only, and neither the audio nor the analysis results reach us. Analyzing a file with these tools does not grant us any license to it, and it does not alter your rights or the rights of third parties in the underlying work. You are responsible for having the right to use the files you analyze.

5. Intellectual property of the site

The site itself — its code, texts, translations, design and brand assets — remains the property of their respective owners. You may link to the tools freely and quote short passages with attribution. Republishing entire pages, the translations or the iconography as your own product requires separate permission.

6. Availability and changes

The service is offered as-is and as-available. Pages may be updated, extended, reorganized or removed at any time; formats, detection behavior and results presentation may evolve. There is no commitment to uninterrupted availability, and there are no paid tiers that promise more.

7. Disclaimer of warranties

To the maximum extent permitted by law, the tools are provided without warranties of any kind, express or implied, including fitness for a particular purpose, uninterrupted availability or error-free detection. Browser capabilities vary; if your browser cannot decode a particular audio format, the tools will say so rather than guess.

8. Limitation of liability

To the maximum extent permitted by law, BPM Key Finder is not liable for any damages arising from the use of the tools or from reliance on their results — including lost profits, lost time, corrupted sessions or publishing decisions based on a detected value. Nothing in these terms excludes liability where such exclusion would be unlawful.

9. Third-party content

The site may contain links to its own pages only in the ordinary course of navigation. If external references ever appear, they are informational; we are not responsible for third-party content or policies.

10. Governing conduct and changes to these terms

These terms may be updated; the date above reflects the current version. Continued use after a change constitutes acceptance of the revised terms. If any provision of these terms is held invalid, the remaining provisions stay in force.

11. Final note

The practical summary: use the tools freely, verify what matters, and treat every number on screen as a well-founded estimate rather than an oracle. That is how the tools are built, and that is how they are best used.

Definitions

In these terms, "the service" means all pages and tools offered under the BPM Key Finder name; "tools" means the individual BPM, key, tempo, tapping, metronome and calculator functions; "results" means any value, label or classification displayed by a tool; and "you" means the person using the service in a browser. Since the service has no registration, the notion of a "user account" deliberately does not appear anywhere in these terms.

Feedback and suggestions

If you send feedback — bug reports, ideas for new tools, corrections to translations — you grant us a non-exclusive, royalty-free right to use and implement it. You remain free to use your ideas elsewhere as well; this clause only prevents suggestions from becoming legal obstacles once they are built into the public site. Feedback is voluntary, and no tool requires it.

Termination

You may stop using the service at any moment by closing the tab — nothing binds you, because nothing was ever registered. On our side, access to the service can be offered, changed or discontinued as described in section 6. Since no data is stored, "termination" leaves no residue: closing your browser ends every session completely.

Entire agreement

These terms, together with the Privacy Policy, form the entire agreement between you and the service regarding its use. They replace any earlier versions shown on this site. If a translation of these terms and the English text differ in meaning, both are intended to say the same thing — and where a court finds they do not, the more user-friendly reading prevails for the provision in question.
