Cookies & storage

Updated 18 October 2026

No advertising cookies or cross-site tracking. RoTune uses local browser storage for the tuner’s settings and offline files.

Website cookies and local storage

The tuner does not set advertising or analytics cookies. It uses browser local storage to remember your settings, language and whether you have seen the tuning tip. These values are not sent to us. Fonts and artwork are served from our own website, without third-party font or media embeds.

A service worker can store website files in your browser’s cache so the tuner can reopen offline. These files are the app’s code, fonts and images, not recordings or a history of your tuning. Local preferences have no automatic expiry; cached files are replaced when the app updates and may also be removed by your browser.

In Settings, turn off Save settings and offline files to remove RoTune’s saved website preferences and offline cache and stop saving them on future visits in that browser. The page reloads and tuning remains available online. One local opt-out value is retained solely to remember this choice. You can also clear all site data in your browser; doing so removes the opt-out too. Microphone permission is controlled separately by your browser.

Website hosting and security

Cloudflare hosts and protects rotune.app. Visiting the website sends ordinary connection information, such as your IP address, requested URL, request time and browser headers, to Cloudflare so it can deliver the site, detect abuse and diagnose failures. This is separate from microphone audio and local tuning settings, which are not uploaded.

Cloudflare also enables browser Network Error Logging for failed connections. Participating browsers may send network-failure details to Cloudflare, such as the requested URL, error type and timing. This is operational diagnostics, not advertising tracking. Cloudflare states that it does not log client IP addresses in that reporting pipeline. Its hosting and security services can process connection information separately.

No cookie was set in our normal-page check on 18 October 2026. If a Cloudflare security challenge is needed, it may use security cookies such as cf_clearance or __cf_bm to validate requests and prevent abuse. These are not used by RoTune for advertising. Security-cookie lifetimes and infrastructure-log retention depend on the Cloudflare service and configuration; see its published cookie and privacy information. We do not keep a separate copy of website visitor logs in a RoTune database.

These local values have no automatic expiry. Clear site data to remove all of them. Turning off storage in tuner Settings retains only the opt-out value. The iPhone app has separate local storage described in our privacy policy.

Open the tuner, then Settings → Save settings and offline files.
