Melody Jam Metronome – Practice with Precision

At Melody Jam Metronome ("we", "us", "our"), we respect your privacy and are committed to protecting your personal data. This Privacy Policy explains what information we collect, how we use it, and what rights you have under the GDPR and other applicable laws.

1. Information We Collect

Local Storage Data. Practice statistics, settings, and preferences are stored locally in your browser. We do not collect or transmit this data unless you opt in to an experimental sync feature.

Analytics Data. We use Google Analytics to collect anonymized usage data, including page views, session duration, referral source, device type, and anonymized IP address. Google may use additional cookies (_ga, _gid, _gat) to distinguish users and sessions.

Server Logs. While we currently do not host user-specific data on our servers, our hosting provider may generate logs containing your IP address, browser type, and interaction timestamps for performance monitoring.

2. Cookies and Similar Technologies

We use cookies and local storage exclusively to support Google Analytics and basic site functionality. You can disable cookies in your browser settings if you prefer not to be tracked.

_ga: Persists for 2 years; distinguishes users.
_gid: Persists for 24 hours; distinguishes users.
_gat: Persists for 1 minute; throttles request rate.

3. How We Use Your Data

We process your data for the following purposes:

To provide and maintain the Site’s core functionality (local storage);

5. Data Security

We implement reasonable technical and organizational measures to protect data in transit (HTTPS) and, where applicable, at rest. However, LocalStorage security depends on your browser’s settings.
