This Privacy Policy explains what information the QuickLingo Chrome extension ("QuickLingo," "the Extension," "we," "us") collects, how it is used, and the choices you have. QuickLingo is built to work with as little data as possible — there are no user accounts, and text you translate is never stored on our own servers.
QuickLingo lets you highlight text on any webpage and instantly translate it or get a plain-language explanation. Results can appear either in a floating widget on the page, or — in page mode — as small cards placed next to the text you selected.
a) Text you choose to translate or explain. When you use the Translate feature, the selected or typed text is sent directly to Google's public translation service to produce the translation. If that service is unavailable or temporarily rate-limited, the same text is sent to MyMemory (translated.net) instead, as a fallback. When you use the Explain feature, the text is sent to our backend server (a Cloudflare Worker), which forwards it to a third-party AI provider (Groq) to generate the explanation. We do not store the content of your translations or explanations on our own servers — it passes through only to generate a response.
b) Auto-explain (optional, off by default). Page mode includes an "Auto-explain" setting. While it is switched on, each new card's text is sent for an explanation automatically, without a separate click. It sends the same kind of text to the same provider described above — only the timing differs — and you can switch it off at any time from the page-mode bar.
c) An anonymous installation ID. When you install QuickLingo, the Extension generates a random identifier (not linked to your name, email, or any personal account) and stores it on your device. This ID is sent to our backend solely to enforce free-tier usage limits and check Pro license status. It cannot identify you personally.
d) Information stored locally on your device (via chrome.storage.local, never transmitted to us except where noted):
You can clear this data at any time by uninstalling the Extension or clearing your browser's extension storage.
e) Payment information (Pro subscribers only). Payment is handled entirely by LemonSqueezy, our third-party payment processor. QuickLingo never receives or stores your payment card details. See LemonSqueezy's Privacy Policy for details.

QuickLingo is not directed at children under 13, and we do not knowingly collect personal information from children.
You can clear your local history and saved words at any time from within the Extension, or uninstall it entirely to remove all locally stored data. Since QuickLingo does not maintain user accounts, most data requests can be fulfilled by clearing local storage. For questions about data sent to our backend, contact us below.
We may update this Privacy Policy from time to time — for example, if we add a new AI provider for the Explain feature. Changes will be posted on this page with an updated "Last updated" date.
