4.12 The Oropen Browser Extension

Our browser extension for Google Chrome and Mozilla Firefox (the "Extension") shows interactive subtitles on YouTube and Netflix, offers a dictionary for the text of the web pages you read, and saves words for your flashcards. Looking words up and saving them requires you to be signed in to it with your Oropen account. This section describes the data it handles; the rest of this Policy applies to it as well.

What the Extension reads, and where:
- On YouTube: the subtitles that YouTube's own player downloads for the video you are watching, together with the video's identifier, title and channel; to show the subtitles in the language you are learning, the Extension may ask the player to switch its subtitle track. The Extension makes no requests to YouTube of its own, and it never downloads, records or uploads video or sound.
- On Netflix: the subtitles that Netflix's own player downloads for the title you are watching, together with the title's identifier and name; to show the subtitles in the language you are learning, the Extension may ask the player to switch its subtitle track. The Extension makes no requests to Netflix of its own, and it never downloads, records or uploads video or sound.
- On other websites — only if you switch on "Dictionary on web pages" in the Extension, which asks your browser for access to all sites: the text around a word, or the text you selected, and only at the moment you look it up with the gesture you chose (for example, a double-click). It reads the surrounding paragraph on your device to find the word's sentence and its language (the language is recognised by your browser itself); otherwise it does not read the pages you visit.
- On oropen.com: while you are signed in there with the same account, the page and the Extension exchange your learning settings (languages, level and interface language) and the words you saved, so that you can add them to a deck.

What the Extension sends to us:
- When you look up a word on YouTube or Netflix: the subtitle line it is in, with the word marked, your two languages and your level; when you translate a line there, or select three words or more of it: that text and your two languages. When you save a word there: the word marked in its line, your two languages and your level, so that an example sentence can be written for your flashcard.
- When you look up a word on a web page: the sentence it is in (at most 400 characters) with the word — or the two words you selected — marked, your two languages and your level. When you select three words or more there and look them up: the text you selected (at most 2,000 characters) and your two languages, to translate it.
- To sign you in, keep you signed in and sign you out: the one-time code that oropen.com gives it when you sign in, and the tokens of its session. It also asks our servers for your name, email address and remaining AI units, to show your account in the Extension.
- Only when you click "Report a problem": the error code, your browser and the Extension's version. In Firefox this is "technical and interaction data", which you allow or refuse when you install the Extension and can change later in its add-on settings; while it is refused, no report is sent.

All of this is sent only to our own servers, with the Extension's access token for your account, and is processed as described in Section 4.3 (AI Processing), including the AI request cache. A look-up is charged to your AI units like the same request in the app, and each video or page appears as one "Browser extension" entry in your billing history. The Extension never sends us the addresses or titles of the pages you visit or the videos you watch, nor your browsing or viewing history, and it contains no analytics, advertising or tracking code.

What the Extension stores, and where:
- In your browser, in the Extension's own storage: the tokens of its session, your name and email address, your learning settings, your preferences (for example the look-up gesture and, for each YouTube channel where you moved the subtitles, their height) and the words you saved.
- A saved word keeps the word, its dictionary form, its meaning and an example, the sentence or subtitle line you met it in, and where you met it: the video (its address, its title and the moment of the line) or the web page (its address and its title).
- When you add saved words to a deck on oropen.com, they are removed from the Extension and become flashcards like any other User Content in the app on your device (and in your Google Drive if you use cloud synchronization, see Section 4.4). Our servers do not keep your saved words.
- On our servers, the Extension's sign-in is kept as one of your account's sessions, like that of a mobile app.

Your choices:
- Switch "Dictionary on web pages" off in the Extension to give back its access to all sites; switch YouTube or Netflix off to stop the subtitles there.
- Sign out in the Extension to delete its tokens and the saved words that were not added to a deck yet (it asks you first).
- "Logout From All Devices" under Settings › Account also ends the Extension's session.
- Removing the Extension from your browser deletes everything it stored there.

We use the data the Extension handles only to provide its features to you. We do not sell it, use it for advertising or to assess creditworthiness, or transfer it to third parties — except to our AI service providers (Section 4.3) to provide those features, where the law requires it, or as part of a business transfer (Section 6.5). Our staff do not read it unless you ask us to (for example in a support request), or where security or the law requires it.

Contract performance (Art. 6(1)(b) GDPR) — to provide the features of the Extension that you use. What the Extension stores in and reads from your browser is strictly necessary for those features, which you request yourself (§ 25(2) no. 2 TDDDG).
