Lopewheel — Privacy Policy

Product: Lopewheel: Video Speed Controller, a browser extension for Firefox and Opera.
Publisher: Zydeno. Contact: [email protected]
Effective date: 19 October 2026.

In short

Lopewheel works entirely inside your browser. The extension stores data only in your browser (storage.local); nothing is sent to Zydeno or anyone else; no analytics, no telemetry, no advertising, no accounts and no remote code. It changes the playback speed of video and audio players and never records, copies or transmits what you watch or listen to.

What is stored, and where

In the browser's extension storage (storage.local) Lopewheel keeps: your settings (how a new page starts, step sizes, favourite speed, preset buttons, whether voices keep their pitch, when the speed tag shows, the badge, your page keys, theme and interface language); the last speed you used (for the "last speed" start mode); for each site where you saved something, the site's host name (for example lectures.example) with its start speed, whether the speed tag shows there, where you dragged the tag, and the time of the last change; and your list of sites where Lopewheel never runs.

While the browser is open, session storage (storage.session) holds, for each open tab, its current speed, the host name of the site open in it and how many players each frame of the tab has. It is cleared when the browser closes.

Lopewheel does not store page addresses, page titles, video titles, browsing history or anything you type. Titles of players are read only to show them in the open popup and are not kept. Uninstalling the extension removes all stored data; you can remove single sites at any time on the settings page.

What happens on a page

On a page where Lopewheel runs, it looks for <video> and <audio> players, sets their playback speed and pitch setting when you ask for a speed other than 1×, and draws a small speed tag next to the player. It reads key presses only to recognise its own page keys, and ignores them while you type in a field. It does not read page text, forms, passwords or cookies, and it changes nothing on a page that has no player.

Permissions

storage — saves the settings described above in your browser.
activeTab — when you click the Lopewheel button or press one of its browser shortcuts, lets the extension work on the current tab only, until you leave that page.
scripting — places the small Lopewheel script into that tab, and into the sites you allowed, so saved speeds apply when a page opens.
Access to sites (optional) — asked only when you choose "Always run on this site", add a site in Settings → Access, or choose "Everywhere". It lets Lopewheel find the players on those pages. You can remove this access in Settings or in the browser at any time.

Export and import

Export saves your settings, saved sites and the never-run list to a JSON file on your computer. You decide where the file goes and who sees it; it contains the host names of sites you saved. Import reads a file you choose and checks it completely before anything is replaced; right after an import or a reset, Undo brings the previous settings back.

Network

Lopewheel makes no network requests of its own. Fonts, icons and translations are inside the extension. The optional "Rate this extension" link opens the store page only if you click it; that site's own privacy policy then applies.

Children

Lopewheel collects no personal data from anyone, including children.

Changes

If this policy changes, the new version is published at this address with a new effective date. Questions: [email protected].
