Privacy Policy

Last Updated: 12/11/2025

1. Our Privacy Commitment

BPMKeyFinder is built on a privacy-first philosophy. Unlike most web services, we don't collect, store, or process your audio files or personal data. This policy explains exactly what happens when you use our service.

2. What We DON'T Collect

Because all audio processing happens locally in your browser, we never see or store:

  • Your audio files—they never leave your device
  • File names, metadata, or analysis results
  • Personal information like names, emails, or account data (we don't have user accounts)
  • Tracking data, analytics, or behavioral information about how you use the tool

3. What We DO Collect

To keep the service running, we collect minimal technical data:

  • Anonymous server logs (IP addresses, timestamps) that are automatically deleted after 7 days
  • Basic error logs to fix bugs and improve service stability
  • Aggregate usage statistics (e.g., total number of analyses per day) without any personally identifiable information

4. Cookies & Local Storage

BPMKeyFinder uses minimal browser storage to remember your language preference and theme settings. No tracking cookies are used. No third-party analytics or advertising cookies are present. You can clear these preferences anytime through your browser settings.

5. Data Sharing

We don't share, sell, or transfer any data to third parties. Period. Your audio files are processed entirely in your browser using WebAssembly. We don't use third-party analytics, advertising networks, or tracking services.

6. Your Rights

Because we don't collect personal data, there's no data to access, modify, or delete. You have complete control:

  • All audio processing happens on your device—you control what files are analyzed
  • No data is sent to our servers, so there's nothing to request or delete
  • You can clear browser storage (language/theme preferences) anytime
  • You can use BPMKeyFinder completely anonymously

7. Security

Your audio files are processed locally using your browser's Web Audio API and WebAssembly. Files never leave your device's memory. The website is served over HTTPS to ensure secure communication. No file uploads means zero risk of server breaches or data leaks.

8. Changes to This Policy

We may update this Privacy Policy occasionally to reflect service improvements or legal requirements. Any changes will be posted on this page with an updated date. Continued use of BPMKeyFinder after changes constitutes acceptance.
