Privacy policy: https://athena.org.tr/en/privacy (section "Browser extension"). The extension sends the text or image you ask it to translate or answer, and your chat messages, only to tilvar.athena.org.tr and nowhere else, and only when you use it. It contains no ads or analytics, does not read your browsing history and sends nothing unless you use it. Your API key, chat history and settings are stored only in your browser; the key goes to the server as a header with each request. On the server, whole-page translations made through the extension, chat messages and images are not stored; single-text translations are written to your translation history under the same rules as other translations.
