What stays on your computer

Your settings, saved words and flashcard progress are stored in your browser (Chrome storage). Captilex reads the subtitles or captions that are already shown on YouTube, Netflix, Google Meet and Microsoft Teams so it can display and translate them. It never records audio or video and never stores meeting links.

Translation

By default, translation uses Chrome's built-in on-device translator, so subtitle text does not leave your computer. YouTube translations come from YouTube itself. When Chrome's translator isn't available for a language, the line or word being translated is sent to our server, which translates it with Cloudflare Workers AI and does not store it.

Payments and licenses

Payments are handled by Dodo Payments (our merchant of record) on its own checkout page; we never see your card or bank details. Our license server stores your license key, your plan and its status, the subscription and customer IDs from the payment provider, the email address the provider shares with us, and random IDs for up to three browsers using the license. We use this only to turn Pro on and to answer support requests.

What we don't do

We don't sell or share personal data, don't show ads and don't use your data for anything other than running Captilex.

Deleting your data

Uninstalling the extension removes everything stored in your browser. To delete your license record, email ashutoshsmartcool@gmail.com.
