Privacy Policy

My Personal DJ ("the app", "we", "our") is a Windows desktop application that works entirely with music files stored on your own device. We are committed to protecting your privacy. This policy explains what information is collected, how it is used, and what choices you have.

The app does not upload, transmit, or share your music files with any server. All audio analysis and playback processing happens locally on your computer.

We collect the minimum amount of information necessary to operate the app and process purchases.

License and activation data. When you purchase a Plus or Lifetime plan and activate your license, your license key and a device identifier are sent to LemonSqueezy (our payments and license provider) to validate your activation. This allows you to use the app across allowed devices and recover your license if needed.

Purchase data. Payments are processed by LemonSqueezy. When you make a purchase, LemonSqueezy collects your payment and billing information. We receive a confirmation of the transaction and your license key. We do not store payment card details.

Support communications. If you contact us at support@mypersonaldj.com, we receive your email address and the content of your message. This information is used only to respond to your inquiry.

Anonymous usage analytics. To understand how the app is used and where it can be improved, the app sends a small number of anonymous events to our own analytics endpoint: when the app is launched, when a playback session starts and how long it lasts, and when a genre-mode trial is started or reaches its limit. This helps us see how many people actually use the app and whether the free trials are useful. It is enabled by default, you are shown a notice the first time the app runs, and you can turn it off at any time from the settings row in the app.

What we do not collect. We do not collect any personal data through analytics. There are no IP addresses (our endpoint never records them), no names or email, and no music library, file names, track titles, or listening history. A random identifier that is not linked to you or your device is used only to count returning installs. We never sell or share this data, and it is never used to identify you.

License data is used to validate that your copy of the app is properly licensed and to allow you to activate the app on permitted devices.

Purchase records are used to fulfill your order and provide customer support related to billing.

Support emails are used solely to respond to your request and resolve issues you report.

We do not sell, rent, or share your personal information with third parties for marketing purposes.

LemonSqueezy (lemonsqueezy.com) processes all payments and manages license key generation and validation. When you make a purchase and activate a license, your payment details, license key, and a machine identifier are handled by LemonSqueezy. The app is configured to allow 30 days of offline use after a successful online validation. Your payment and billing details are governed by LemonSqueezy's privacy policy and terms. We recommend reviewing them before completing a purchase.

LemonSqueezy is only used for its specific purpose (payments and licensing) and is not given access to your music library or usage data.

License activation state is stored locally on your device in a file managed by the app. Your email address used for purchase is stored by LemonSqueezy according to their own policies.

We take reasonable technical precautions to protect the data we handle, but no system is completely secure. We encourage you to use a strong password for your email account to protect your purchase confirmation.

If you are located in the European Union or another region with privacy rights legislation, you may have the right to access, correct, or delete personal information we hold about you.

To exercise these rights, please contact us at support@mypersonaldj.com. We will respond within 30 days. In most cases, the personal information we hold is limited to your support correspondence and the activation record managed by LemonSqueezy, which you can also request to be removed directly through them.

My Personal DJ is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

We may update this Privacy Policy from time to time. When we make material changes, we will update the date at the bottom of this page. Continued use of the app after changes are posted constitutes your acceptance of the updated policy.

If you have any questions about this Privacy Policy or how your data is handled, please contact us at support@mypersonaldj.com.
