Privacy policy — ttgen
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:
- Google Gemini or OpenAI, if you use AI and have added that provider’s key
- Wikipedia or Wiktionary, for encyclopedia or dictionary results
- Datamuse, for related words on a dictionary result
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
- No analytics, advertising, or crash reporting
- No sale of personal information
- No mailing list or developer-operated database
- No collection of the full page, cookies, or passwords
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.
