Privacy Policy

Last Updated: June 17, 2026

1. Client-Side Processing Guarantee

Playlist Master Studio is designed as a browser-first audio mastering utility. When you drag and drop audio files into the workspace, the files are decoded, analyzed, mastered, and rendered entirely inside your local computer's temporary memory (RAM) using client-side technologies (Web Audio API, Web Assembly, Canvas APIs). **No audio file is ever uploaded to Firebase Storage, external database servers, or third-party audio service APIs.**

Audio Processing vs. Advertising Data: Please note the distinction between your creative media assets and site utilities. Source audio files are processed locally in the browser and are not uploaded to Firebase Storage or external audio processing servers. However, if ads are displayed, Google AdSense and its partners may use cookies or similar technologies for ad delivery, measurement, fraud prevention, and personalization where applicable.

2. Data Collection & Accounts

We do not require account creation, registration, email sign-ups, or login details to use our core studio services. Consequently:

• We do not store, collect, or share personal identifying information (PII).
• We do not keep history records of what files you have uploaded or processed.
• We do not sell user processing history to third-party ad networks.

3. Hosting & Security

The static assets of the website (HTML, CSS, JavaScript, fonts, and images) are securely delivered to your browser via Firebase Hosting (Google CDN). While Firebase Hosting registers standard technical logs (such as IP addresses and browser headers) solely to deliver static files and monitor security incidents, Google does not access or process your local audio buffers.

4. Cookie Notice

This website may use cookies or similar technologies for advertising, ad measurement, fraud prevention, and basic website delivery. Users can manage cookies through their browser settings. Some advertising features may depend on user consent or regional privacy requirements. If Google AdSense privacy and messaging configurations are enabled in the future, these settings may adjust cookies policies accordingly.

5. Advertising and Cookies

Playlist Master Studio may display advertisements through Google AdSense. Third-party vendors, including Google, may use cookies, device identifiers, or similar technologies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables Google and its partners to serve ads to users based on visits to Playlist Master Studio and/or other sites on the internet.

Users may opt out of personalized advertising by visiting the Google Ads Settings. Users can also learn more about how Google uses information from sites and apps that use Google services by visiting the Google Privacy & Terms advertising resources page. If third-party ad networks or vendors serve ads on this site, they may also use cookies or similar technologies according to their own privacy policies.

6. Changes to This Policy

We reserve the right to modify this Privacy Policy as browser capabilities or website architecture updates. Any updates will be published directly on this page with an updated timestamp.
