Signal Tools — Privacy Policy
Last updated: June 21, 2026

Signal Tools is a browser extension made by Enova Studio that helps you publish podcast episodes on the Signal Ghost theme. It turns a YouTube episode into a transcript, chapters, and show notes, and can add a guest to your own Ghost site. This policy explains exactly what the extension does with your data.

The short version: the extension stores your keys and content on your own device and sends them only to the services you choose to connect. We do not receive your data, and there is no analytics or tracking.

What the extension stores on your device
The following are saved in the browser's local extension storage, on your computer only. They are never synced to your other devices and are never sent to Enova Studio:

Your Google Gemini API key.
Your Ghost site URL and the credential you enter (a Staff Access Token or an Admin API key).
Your Signal Tools license key.
Your settings, the background job queue, and your generation history (transcripts, chapters, and show notes for episodes you have processed).
You can view, re-copy, export, or delete your history at any time from the History tab, and you can disconnect a license or remove your keys from Settings.

Where your data is sent, and to whom
The extension only contacts a service when you ask it to, and only sends what that service needs:

YouTube (youtube.com): when you import an episode, the extension reads the watch page you have open to obtain the video's title, description, existing chapters, and caption track. It reads this page; it does not send your personal data to YouTube.
Google Gemini (generativelanguage.googleapis.com): the episode's caption text is sent to Google's Gemini API, using your own API key, so the model can clean the transcript and write chapters and show notes. This is governed by Google's privacy policy and your agreement with Google. Timing always comes from YouTube, never the model.
Your own Ghost site: only if you choose to connect Ghost and click "Send to Ghost" or "Add guest." The extension sends the draft content and your Ghost credential directly to the site URL you entered. Nothing is published live; results arrive as drafts for you to review.
Lemon Squeezy (api.lemonsqueezy.com): your license key is sent to Lemon Squeezy to activate, validate, or deactivate your license. Only the license key and a device identifier are sent; no other data. This is governed by Lemon Squeezy's privacy policy.
Enova Studio does not operate a server in this flow and does not receive your keys, your transcripts, or your show content.

Analytics and error reporting
The extension contains no analytics and no tracking.

Optional error reporting is off by default. If you turn it on in Settings, the extension may send sanitized error messages to help us fix bugs. Before sending, it redacts API keys, email addresses, license keys, and transcript content. You can turn it off again at any time.

Data retention and deletion
Your keys, settings, and history remain on your device until you delete them or remove the extension. Removing the extension, or clearing the browser's extension storage, deletes everything the extension has stored locally. To free your license seat on this device, use "Deactivate" in Settings before removing the extension.

Data we do not collect
We do not sell or share your data. We do not build advertising or marketing profiles. We do not collect your browsing history. The extension reads only the active YouTube tab you are importing, and only when you act on it.

Children
Signal Tools is a tool for podcast publishers and is not directed to children under 13.

Changes to this policy
If this policy changes, we will update the "Last updated" date above and post the new version at this URL. Material changes will be noted in the extension's release notes.
