Privacy Policy — Structune

Last updated: May 2026

Structune does not collect, transmit, or share any personal data with any third party. The only external network request the extension makes is the Gemini API call you explicitly initiate by clicking Generate. All other data processing occurs locally on your device.

Data Handling

Data	Where it stays	Sent externally?
Gemini API key	Device only (`chrome.storage.local`)	Sent only to Google's Gemini API endpoint when you click Generate or Verify
Builder input & generated result (draft)	Device only (`chrome.storage.local`)	The input text is sent to Google's Gemini API when you click Generate — no other transmission
Saved prompts (Library)	Device only (`chrome.storage.local`)	No
Settings (language, sort order, daily limit)	Device only (`chrome.storage.local`)	No

What the Extension Does

Sends your builder input to the Google Gemini API using the API key you provide, when you click Generate.
Displays the structured spec result locally in the popup.
Stores your saved prompts, settings, and draft locally in your browser.
All processing happens on your device. Structune does not operate any backend server.

Google Gemini API

When you click Generate, the text you entered in the builder is sent to Google's Gemini API (generativelanguage.googleapis.com) using your own API key. This request is made directly from your browser to Google's servers — no intermediate server is involved.

Google's privacy policy governs how your data is handled by the Gemini API: https://policies.google.com/privacy
