Litancy Privacy Policy

Last updated: 11 September 2026

Litancy is a browser extension that shows bilingual subtitles on video pages. It is built and maintained by an individual developer and has no company, account system, or analytics behind it.

What Litancy does with data

Caption text. To produce the translated line, Litancy sends the text of the caption currently on screen (and the next few captions) to the translation service you select in its settings. When you click a word, that word is sent the same way. The available services are:

Google Translate public endpoints (clients5.google.com,

translate.googleapis.com)

Lingva (lingva.ml), a public mirror of Google Translate
MyMemory (api.mymemory.translated.net)
A LibreTranslate server whose address you enter yourself

These services receive only the caption text, the source and target language codes, and, for MyMemory, an email address only if you choose to enter one. Their handling of that text is governed by their own privacy policies. Litancy sends nothing else: no page URL, no video identifier, no account information.

Settings. Your language, engine, and display preferences are stored with chrome.storage.sync, which Chrome may synchronise across your own signed-in browsers. Litancy cannot read this data outside the browser.

Translation cache. Translated captions are cached locally in chrome.storage.local, keyed by site and video path, so repeat viewing does not re-translate. The cache never leaves your browser.

Video streams. On sites that deliver captions inside a video stream (for example the Mux player used by DailyWire), Litancy reads the caption files that the page's own player already fetches, using the same signed address the page uses. That address is kept in memory only and is never stored or transmitted anywhere except to the site's own content servers.

What Litancy does not do

No analytics, telemetry, crash reporting, or advertising.
No accounts, sign-in, or identifiers of any kind.
No collection of browsing history, page contents beyond captions, or

personal information.

No remote code: all code ships inside the extension package.

Permissions

storage — save settings and the local translation cache.
Host access to the translation services listed above — perform

translations from the background service worker.

Optional host access (https://*/*) — requested only when you configure a

LibreTranslate server, and only for that server's origin.

Content scripts on youtube.com and dailywire.com — find the video,

read its captions, and draw the subtitle overlay.
