Privacy

Cuelatch is a static website with no server-side component. There is no database, no account system, and no analytics. The short version is that your files never leave your device, and the site has nothing to collect them with.

The rest of this page is the long version, written so the claims can be checked rather than taken on trust.

Your files

Subtitle files, video files and audio files that you open are read by your browser and held in memory on your own machine. They are never transmitted anywhere. Corrected files are generated locally and saved by your browser directly to your device.

Automatic detection, which reads a video or audio track to work out the offset, also runs entirely in the browser. The audio is decoded locally, reduced to a speech-energy envelope, and discarded.

None of this is a policy commitment that could quietly change — it is how the tool is built. There is no endpoint to send a file to.

What is stored on your device

One value, in localStorage:

• theme — whether you chose the light or dark appearance, so the choice survives a reload. Set only if you press the theme control.

There are no cookies. Nothing is written to sessionStorage or IndexedDB. Clearing site data removes the single value above and nothing else of yours exists to remove.

A service worker also caches the site's own pages and assets so the tool works offline. That cache holds this website's files, never yours.

Third parties

There are none. The site loads no external scripts, no web fonts, no tracking pixels, no embedded media and no content delivery network. Typefaces are the ones already installed on your system. If you open your browser's network inspector while using the tool, every request you see will be to this domain, and there will be no requests at all once the page has loaded.

Server logs

The pages themselves have to be served from somewhere, and that hosting is provided by Cloudflare Pages. Like any web server, it records requests for pages and assets, which typically includes your IP address, the time of the request, the page requested and your browser's user agent. Those records are a byproduct of delivering the page. They contain no information about the files you open, because that information never reaches any server.

Children

The site collects no personal data from anyone, of any age.

Your rights

Rights such as access, correction, erasure and portability apply to personal data held about you. Cuelatch Ltd holds none through this site, so there is nothing to access or erase. Any request concerning hosting logs can be sent to the address below.

Changes

If this policy changes, the date at the top of the page changes with it. A change that widened what is collected would require the site to gain a backend, which would be a visible change to how it works and would be stated plainly here.
