Cookie Policy
What cookies and local storage are
Cookies are small text files a website can place in your browser, and local storage is a related browser feature that keeps small pieces of data on your device. Both let a site remember things between visits — like a preference you chose — without building a profile about you on a server.
What we set
Piano Online keeps things minimal. The only data we store in your browser is two preference entries in local storage:
| Name | Purpose | Type | Duration |
|---|---|---|---|
| po-skin | Remembers your color theme choice | Local storage | Until cleared |
| po-lang | Remembers your language choice | Local storage | Until cleared |
These entries never leave your device, are never sent to us, and contain nothing personal — just a theme name and a language code. Today, we set no cookies of our own; everything above is strictly necessary to make the site behave the way you asked it to.
Third-party cookies
When advertisements are shown on the site, our advertising partners may set their own cookies. In particular, Google AdSense and its partner vendors may use cookies to serve ads based on your prior visits to this website or other websites. These cookies enable personalized advertising — ads chosen for you rather than shown at random.
If you would rather not receive personalized ads, you can opt out in two places:
- Google Ads Settings — control the ads Google shows you
- www.aboutads.info — opt out of third-party vendor cookies for personalized advertising
Opting out does not remove ads; it just makes them less tailored to your browsing.
How to manage or clear cookies
- Chrome: Settings → Privacy and security → Third-party cookies, or site-specific data via the lock icon in the address bar
- Safari: Settings → Privacy → Manage Website Data
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data
- Edge: Settings → Cookies and site permissions → Manage and delete cookies
Clearing site data for pianoonline.org removes your theme and language preferences; the site simply falls back to its defaults the next time you visit.
