Privacy policy — ttgen

Last updated: 5 September 2026

ttgen is a Chrome extension that explains text you highlight on a web page. It is made by wondersnwhispers.

The developers do not run a ttgen server or user accounts. We do not receive your API keys, lookups, browsing history, or settings.

What stays on your device

API keys you add, your settings, and cached explanations stay in this browser. They are not uploaded to us. Uninstalling the extension removes them.

What is sent when you look something up

Nothing is sent until you look something up. Then the text you looked up may go to the service that provides the explanation:

If you turn on surrounding context, a short nearby sentence may be included. A follow-up may include the previous explanation.

Your API key is sent only to that provider. If you never add a key and never use AI, nothing is sent to Google or OpenAI.

What we do not do

Opening a result in Gemini or ChatGPT

If you open an AI result on Gemini or ChatGPT’s website, that visit is between you and Google or OpenAI.

Permissions

Chrome asks for storage, so keys and settings can stay on this device, and for permission to run on web pages, so the explanation can appear next to what you highlighted.

Children

ttgen is not directed at children under 13.

Changes

We will update this page when our data practices change. The date at the top is the latest revision.
