THE SHORT VERSION

The extension has no server, no account and no analytics. Nothing about you is
collected, stored remotely or sold. No data ever reaches Nocturne Voss, because
there is nothing on our side to reach. The only network requests the extension
makes are the ones needed to read the transcript of the video you are already
watching, plus an optional call to a model provider that you configure
yourself.


WHAT THE EXTENSION READS

When you click the toolbar icon on a YouTube video, the extension reads:

- the video's ID, title, channel, length, publication date and description
- the caption track for that video
- the video's chapter markers

It reads these from the YouTube page already open in your tab, using YouTube's
own endpoints. Those requests are made from inside the page and carry your
existing YouTube session cookies, exactly as they would if you opened the
transcript panel yourself. The extension never reads, copies or transmits those
cookies.

It reads nothing until you click the icon, and it reads nothing from any other
tab or site. There is no content script running in the background: the
extraction code is injected into the one tab you are on, at the moment you
click, under the activeTab permission, and it stops when it is done.


WHAT IS STORED, AND WHERE

Stored on your own machine using chrome.storage.local:

- your settings (output mode, language preference, cleaning options)
- a count of AI-Ready runs on this machine, used only to decide whether the
  one-time "rate it" link has already been offered
- any model API key you chose to save
- the support link, if you replaced the default one

Stored temporarily in chrome.storage.session, which the browser clears when you
close it:

- the most recent extracted transcript, so reopening the popup is instant

None of this leaves your machine. There is no sync, no backup and no remote
copy. Uninstalling the extension deletes all of it.


THE OPTIONAL MODEL CALL

If, and only if, you configure a model provider in Settings and press "Run
model", the extension sends the cleaned transcript and the video's title,
channel and chapter list directly from your browser to that provider:

- Anthropic (api.anthropic.com)
- OpenAI (api.openai.com)
- Google Gemini (generativelanguage.googleapis.com)
- OpenRouter (openrouter.ai)

There is a fifth option, "Nocturne Cloud", which is a licence-key path built
into the code for a possible future hosted plan. It has no default address: it
does nothing at all unless you select it and paste in an endpoint URL yourself,
and if you do, the transcript is sent to that address instead of to a provider
above. No such service is running today, so in practice this option is inert.

The request goes from your browser to whichever destination you chose. It does
not pass through any Nocturne Voss server, because there is none. What the
provider does with the data is governed by that provider's own privacy policy
and the terms of your account with them.

The extension asks for permission to reach a provider's domain only at the
moment you select that provider, and you can revoke it in your browser's
extension settings.

AI-Ready itself does not require any of this. With no provider connected it is
generated locally, in your browser, and nothing leaves your machine at all.


YOUR API KEYS

A key you paste into Settings is stored locally and used only as the
authorization header on requests to the provider it belongs to. It is never
transmitted anywhere else, never logged, and never included in any other
request. Deleting it from Settings, or removing the extension, removes it.


LINKS OUT OF THE EXTENSION

The popup contains ordinary links: the studio wordmark, the support link, and
the provider sign-up links on the Settings page. Clicking one opens a normal
browser tab in the usual way. The extension attaches nothing to those requests,
sends no identifier with them, and is not told whether you followed one. Sites
you land on have their own privacy policies.


WHAT THE EXTENSION DOES NOT DO

- No analytics, telemetry, crash reporting or usage tracking
- No advertising and no advertising identifiers
- No selling or sharing of data with third parties
- No reading of browsing history, bookmarks, cookies or other tabs
- No content script running in the background on YouTube or anywhere else
- No account, no sign-up, no email address collected
- No third-party libraries bundled in the package, so no third-party code runs


PERMISSIONS, AND WHY EACH ONE EXISTS

activeTab
  To read the transcript from the YouTube tab you are on, only at the moment
  you click the icon.

scripting
  To inject the extraction script into that tab at that moment. It is not a
  persistent content script.

storage
  To save your settings and the daily count on your machine.

Provider domains (optional host permissions)
  Only granted when you connect a model provider, only for that provider's
  domain, and revocable at any time in your browser's extension settings.


CHILDREN

The extension is a developer and study tool and is not directed at children
under 13. It collects no personal data from anyone, of any age.


YOUR RIGHTS

Data protection law gives you rights of access, correction, deletion,
portability and objection over personal data held about you. We hold none:
there is no server, no database and no account, and nothing about you is ever
transmitted to us. Everything the extension stores is on your own machine,
under your own control, and you can read it, change it or delete it at any time
through the Settings page or by removing the extension.


CHANGES

Any change to this policy is published with a new version of the extension and
a new date above. Any change to what leaves your machine changes this policy in
the same release.
