Terms of Use

Last updated: July 2026

These terms are short because the service is simple: SyncMySubs is a set of free subtitle tools that run entirely in your web browser. By using the site you agree to the terms below.

What the service is

SyncMySubs provides browser-based tools for converting, re-timing, repairing and editing subtitle, caption and lyric files. All processing happens locally on your device: your files are never uploaded to us, we operate no server that could receive them, and we never see their contents. The tools are free to use, with no account and no sign-up.

Your files and your responsibility

Your files remain entirely yours. Because they never leave your device, we claim no rights over them and take no copies. In return, you are responsible for what you process: use the tools only on subtitle and video files you created, licensed, or otherwise have the right to work with, and only for lawful purposes.

No warranty

The tools are provided as-is and as-available, without warranty of any kind. We work hard on correctness, and each tool tries to tell you honestly what a conversion keeps and what it drops — but subtitle formats are messy, real-world files are messier, and we cannot promise the output will always be complete, accurate, or fit for a particular purpose. Always keep your original file. Every tool here writes a new file rather than touching the one you loaded, so your original is safe unless you delete it yourself.

Limitation of liability

To the maximum extent permitted by law, SyncMySubs and its operator are not liable for any damages arising from your use of the site — including lost data, lost time, or problems caused by a converted file downstream. A free, local tool is offered in good faith; if that allocation of risk isn't acceptable, please don't use the site.

Acceptable use

Don't attack, overload, or attempt to disrupt the site, and don't scrape or republish its content wholesale. That's it — there is nothing else to abuse, because there are no accounts and no stored data.

Advertising

The site shows a single advertisement below each tool, served by Google AdSense, and accepts voluntary tips. Ads never receive or interact with your files. How advertising cookies are handled is covered in the privacy policy.

Changes

The tools may change: pages are occasionally improved, merged, or retired (with redirects, so links keep working). These terms may also be updated from time to time; the date at the top reflects the latest revision. Continued use of the site after a change means you accept the updated terms.
