Privacy Policy
Last updated: 17 August 2026
Without an account
You can use the app without signing in, and in that case we hold no account for you — only the short-lived server logs described below. Your video list, saved words, and settings live in your browser's own storage, on your device — clearing site data removes them. Captions and translations are cached on our server per video, not per person: the same cached subtitles are served to everyone who opens that video.
With a Google account
Signing in uses Google Sign-In. We receive and store three things from Google: your email address, your name, and Google's stable account identifier. We use them for exactly one purpose — knowing which plan your account is on. Signing in sets one cookie (le_sess) that keeps you signed in for up to 180 days; it identifies your account and nothing else. We never see your Google password.
Server logs
Like most websites, our server records each request it answers: the IP address it came from, the time, the page or file requested, and the browser's self-description. We keep these for 30 days and then they are deleted automatically. They exist to keep the service secure and working — spotting abuse, investigating whether something was accessed, and diagnosing errors. We do not use them to build a profile of you, and we do not share them.
Analytics
We use Google Analytics to understand which features are used, configured without advertising features. We show no ads, and we do not sell or share personal data with anyone.
Third parties
Videos play in YouTube's own embedded player, which is governed by Google's privacy policy. To produce translations, we send video caption text to a machine-translation provider — the text of the video, never anything about you.
Deleting your data
Sign out at any time from Settings. To delete your account record entirely, email us and we will remove it.
