The short version
The calculators on CalcSunny run entirely in your browser. The values you enter are not sent to us or stored on our servers. The music tools work the same way: audio files you open are decoded and processed by your own browser and are never uploaded.
Information we collect
We don't ask for your name, email or any account. Like most websites, our hosting provider may keep standard server logs (such as IP address, browser type and pages requested) for security and to keep the site running.
Advertising and cookies
We plan to show ads to keep the site free. Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies lets it and its partners serve ads based on your visits. You can opt out of personalized advertising in Google Ads Settings, or visit aboutads.info to opt out of some third-party vendors' cookies. Where required by law, we'll ask for your consent before personalized ads are shown.
