Synopedia – Synonyms & Antonyms Privacy Policy

Last updated October 13, 2026. Published by BIGBANG MEDIA, Laval (France).

The Synopedia – Synonyms & Antonyms extension (Chrome, Edge, Firefox) does not collect, store on any server or transmit any personal data or usage data.

Works offline. The synonym and antonym lists are bundled with the extension. It sends no request to any server, ours or anyone else’s. There is no account, no cookie, no advertising, no analytics and no tracking.

Page access. Only when you choose “Synonyms for…” in the right-click menu does the extension read the page language and the selected word, to show the result and, if you click a synonym, replace that word in the text box. Nothing it reads is kept or sent anywhere.

Local preferences. Your chosen language and your last searched word are kept in your browser’s storage, on your device only. They are deleted when you remove the extension.

Links to the website. The “See all synonyms on Synopedia” link opens synopedia.com in a new tab, only when you click it. The address includes a tag showing that the visit comes from the extension. The website’s own legal notice then applies.
