Ambient Spanish is a browser extension that helps you passively learn English or Spanish vocabulary while you browse. This page explains what data the extension touches and, just as importantly, what it does not do.
Ambient Spanish does not collect, transmit, sell, or share any of your data. It has no backend server. Everything it stores stays inside your own browser.
chrome.storage.sync API. This data is stored locally and, if you have Chrome Sync turned on, is synced across your own signed-in browsers by Google — the same mechanism Chrome uses for your bookmarks or browser settings. The developer of this extension has no access to this data.chrome.storage.local, kept only on your own device.chrome.storage.session, which is cleared automatically when you close your browser.To power the "word swap" feature, the extension's content script reads the visible text of pages you browse, entirely inside your own browser, to find matching words to swap for their translation. This text is never transmitted anywhere, logged, or sent to any server — the extension has no server to send it to.
The "pronounce this word" feature uses your browser's built-in Web Speech API. Depending on your browser and operating system settings, some voices are processed entirely offline while others may be provided by your browser or OS vendor's own speech service (for example, some Chrome voices are served by Google). This is a function of your browser/OS configuration, not something Ambient Spanish controls, transmits data to, or has any relationship with beyond calling the standard browser API.
The "Export to file" / "Import from file" feature in Settings reads and writes a plain JSON file directly on your own computer. This file is never uploaded anywhere by the extension — it only goes wherever you choose to save or share it yourself.
Settings includes an optional "Donate via PayPal" button. Clicking it opens PayPal's website in a new tab. Ambient Spanish does not share any information with PayPal — PayPal's own privacy policy applies to anything you do on their site.
Ambient Spanish does not require sign-in, does not use cookies, does not include any analytics or advertising SDKs, and does not make any network requests of its own.
Ambient Spanish is not directed at children and does not knowingly collect any information from anyone, of any age — see above: it doesn't collect information at all.
If this policy ever changes, the updated version will be posted at this same page with a new "Last updated" date.
