Cookie Policy

Last reviewed on April 23, 2026

What this page covers

This Cookie Policy explains the cookies and similar browser storage technologies used on harmonoise.com. It is a companion to the Privacy Policy, which describes the broader handling of information. The goal here is to be specific: which cookies, from whom, for what, and how to opt out.

What cookies are

A cookie is a small text file stored by your browser when a website asks it to. Cookies can be set by the site you are visiting ("first-party cookies") or by other services embedded on the page ("third-party cookies"). Sites also use related technologies such as Local Storage and Session Storage, which behave similarly but stay entirely inside the browser. This policy covers all of these.

Cookie categories used on Harmonoise

1. Strictly necessary

Harmonoise does not currently set any first-party cookies of its own for login, sessions, or security. The site is a static site with no user accounts. "Strictly necessary" therefore covers only what the hosting provider sets by default (if anything) for security or request routing.

2. Preferences (Local Storage)

The tools use your browser's Local Storage — not traditional cookies — to remember small pieces of UI state across visits:

  • Theme preference (dark or light) — key name similar to harmonoise-theme.
  • Last-used tool settings such as metronome BPM or tool volume — small numeric or string values under keys prefixed with harmonoise-.

Local Storage stays on your device and is not transmitted to any server. You can clear it at any time from your browser's site-data settings.

3. Analytics (Google Analytics)

The site loads Google Analytics 4 (measurement ID G-9L6JR4H0K1). Typical cookies set by GA4 include:

  • _ga — distinguishes unique browsers; typical lifetime about 2 years.
  • _ga_<container-id> — session state for the specific GA4 property; typical lifetime about 2 years.

These are used to understand which pages are visited, whether anything is broken, and rough traffic volume. They do not contain personal information such as your name or email. Analytics data is not shared with advertisers.

4. Advertising (Google AdSense and its partners)

The site uses Google AdSense to display ads. Google and other third-party vendors may set cookies on your browser to measure and serve ads. Typical advertising cookies and identifiers include:

  • __gads and __gpi — used by Google to measure ad performance and limit how often the same ad is shown.
  • IDE, DSID, NID, ANID and similar cookies under doubleclick.net and google.com — used for advertising measurement and, where permitted, ad personalization.
  • Cookies set by other advertising partners that Google works with, if your region permits personalized advertising.

The exact set of cookies depends on your region, your browser settings, and whether personalized advertising is allowed where you are. Harmonoise does not receive the personal data that Google uses to target ads.

How to opt out or change preferences

You have several options, which you can combine:

  • Google Ad Settings: turn off personalized advertising from Google at google.com/settings/ads. Ads will still be shown, but will be non-personalized.
  • YourOnlineChoices (EEA/UK): opt out of personalized advertising from participating vendors at youronlinechoices.com.
  • Digital Advertising Alliance (US): opt out at aboutads.info or, for mobile apps, via the AppChoices app.
  • Google Analytics opt-out: install the Google Analytics opt-out browser add-on to stop Analytics tracking across sites that use it.
  • Your browser's cookie controls: every major browser lets you block third-party cookies, clear cookies for a specific site, or clear all browsing data. Doing so will remove Harmonoise's Local Storage preferences as well.
  • Global Privacy Control (GPC): if your browser sends a GPC signal, Harmonoise treats it as an opt-out of sale/sharing for personalized advertising in jurisdictions where that mechanism applies.
  • Tracker blockers: content-blocker extensions can prevent most analytics and advertising scripts from loading at all.

Consent in the EEA, UK, and comparable regions

Where applicable law requires consent for non-essential cookies, Harmonoise aims to honor consent signals passed by the browser or displayed by a consent prompt served by Google's own tooling. If consent has not been given or has been withdrawn, Google AdSense is instructed to serve non-personalized ads where that option is available. You can also opt out through the external tools linked above at any time.

Do Not Track

Browsers send a variety of privacy signals (Do Not Track, Global Privacy Control). Harmonoise forwards applicable signals to Google's services, but support and behavior depend on the third party. The opt-out options above give you direct control regardless of browser signal support.

Third-party links

Pages on Harmonoise include links to third-party sites — for example, Google's Ad Settings, Google's Privacy Policy, and the regional opt-out tools mentioned above. Those sites have their own cookie and privacy practices, which are not controlled by Harmonoise.

Changes to this Cookie Policy

Cookies and advertising practices change over time. When material changes are made, the "Last reviewed on" date at the top of this page is updated. You can check this page periodically for the current state.
