Privacy policy

This policy covers onlinetuner.app, run by Appcellent Yazılım Hizmetleri Anonim Şirketi (“Appcellent”, “we”). Short version: your audio never leaves your device, and there are no accounts and no ads.

Microphone

When you press Start, your browser asks for microphone permission. The sound is analysed in the page, on your device, to find its pitch. It is not recorded, stored or sent to us or anyone else. You can withdraw the permission at any time in your browser’s site settings.

What we collect

• Server logs. Our host, Cloudflare, processes your IP address and request details to deliver the site and protect it from abuse.
• Preferences. Your reference pitch (A4), last instrument and tuning, tuning fork frequency and the visit counter mentioned below are saved in your browser’s local storage. Only the coarse visit count is ever sent, as part of the anonymous usage counts.

Anonymous usage counts. To learn whether the tools work, the page sends short, anonymous events to our own server — for example “tuner started”, “microphone allowed or blocked”, “a string reached in tune”. Each event carries only the page, the instrument and tuning, a coarse device type (phone, tablet or computer), the operating system and browser family, where the visit came from (search engine, AI assistant, direct or other link), the visitor’s country as reported by Cloudflare, a rough count of visits kept in your own browser (for example “2nd visit”) and a random number made for the current page visit, which is not stored and not linked to you. There is no user ID, no cookie, no fingerprinting, and your IP address is not stored with the events. The counts are kept in Cloudflare Analytics Engine.

The website uses no cookies and no third-party analytics or advertising scripts.

What we do not do

We do not sell data, show ads or record audio.
