Cookie Policy
Last updated: 26 July 2026
Most of what this site stores is not a cookie at all — it is local storage, which stays on your device and is never sent to us. The exception is advertising, which is served by Google and does set cookies. Everything is listed below.
What is stored
| Name | Type | Set by | Purpose | Lifetime |
|---|---|---|---|---|
| playlist_history | Local storage | This site | Keeps your 20 most recent analyses so you can revisit them without re-running. Never transmitted to us. | Until you clear site data |
| theme | Local storage | This site | Remembers whether you chose the light or dark appearance. | Until you clear site data |
| cookie-consent | Local storage | This site | Records whether you accepted or declined the banner, so it is not shown on every visit. | Until you clear site data |
| Vercel Analytics | Cookieless | Vercel | Counts page views in aggregate. Vercel Analytics does not set a cookie and does not build a cross-site profile. | n/a |
| Google AdSense | Cookies and device identifiers | Selects and measures advertising where ads are enabled. Google may use these to limit how often you see an ad and, depending on your Google account settings, to personalise it. | Set by Google; see its policy |
How to refuse or remove them
- • Everything this site stores can be erased by clearing site data for this domain in your browser settings. That also erases your analysis history, which is the only copy.
- • Advertising personalisation is controlled through Google's own settings at My Ad Center, which applies across every site that uses Google advertising, not just this one.
- • Blocking third-party cookies in your browser stops advertising cookies without affecting the analyzer, which does not depend on them.
- • The tool works with all of it disabled. Analysis, exports, and every calculation function normally; you simply lose the convenience of saved history and remembered appearance.
