JUCEY extension privacy practices

Last updated: October 3, 2026

1. Share what I read (off until you turn it on)

If you turn this on, then when a LinkedIn or X post stays at least half visible on your screen for about 0.8 seconds, the extension records:

• The platform (LINKEDIN or TWITTER).
• The author’s public handle.
• Any hashtags visible on the post.
• How many milliseconds the post was on screen.
• Whether you clicked Like, Repost, or Comment on it (yes / no).

It does not send the post text, the post URL or id, or the author’s display name. These records are stored with your Jucey account so we can point our trend research at the creators and topics you read, and rank creators you read closely higher in your own feed. Raw records are deleted automatically after 7 days.

Trend pool (extra opt-in, off by default)

While “Share what I read” is on, you can also turn on “Also add public post metadata to the JUCEY trend pool” in Options. The extension then also sends these public fields of posts you scroll past:

• Post URL and id.
• Author handle and display name as shown on the post.
• Hashtags and media types (image / video / poll / article).
• Public engagement counts (likes / comments / reposts / views).

We never store the body of the post in the pool, and the pooled record is not tied to your account— we only increment a counter of how many Jucey users have seen each post. Pooled rows expire after 28 days. You can email dpo@jucey.app to request earlier deletion.

2. Learn from my posts and comments (off until you turn it on)

If you turn this on, then when you like, repost, bookmark, or comment on a LinkedIn or X post, the extension sends that action together with the post text, the post URL, the author, hashtags, and — for comments — the text you wrote. We use it only for your own voice and interest profile:

• Phrases from comments you write are added to your preferredPhrases list with a weighted-decay model (frequent phrases stick, stale ones fade).
• Hashtags and keywords from posts you like, repost, or bookmark feed your recurringThemes.
• Up to 12 recent snippets (about 300 characters each) are kept in your voiceProfile as context the AI can cite.

This data is per-user only. It is scoped to your account, never pooled, and never shared with other Jucey users. Raw engagement records are deleted automatically after 90 days, and deleting your account deletes them immediately.

3. How to turn them on or off

• Open the extension’s Options page (right-click the Jucey icon → Options) and go to “What the extension sends in the background”. Switch “Share what I read” or “Learn from my posts and comments” on or off.
• Turning a stream off stops it in your browser immediately. The extension also updates your Jucey account so our servers refuse that data; once both are off, uploads from any version of the extension are refused.
• Turning a stream off does not erase what was already learned. Phrases and themes already in your voice profile stay (you would notice if the AI suddenly forgot how you write). Email dpo@jucey.app for a full reset of preferredPhrases / recurringThemes / engagement records.
• Earlier versions of the extension had these streams on by default. After updating, they are off until you choose again. Removing the extension stops everything.

4. Things you do on purpose

These send data only when you click, and work whether or not the background streams are on:

• Save to Jucey sends the post text, author, link, visible engagement counts, your juiciness rating, and any note you add to your private Jucey library. Saved posts are visible only to you.
• Research a creator and chat send the selected post and your question to Jucey to answer it.
• Snap (Alt+Shift+S, or “Ask Jucey about this screen”) takes a screenshot of the tab you are on, only when you trigger it, and sends it with your question to Jucey to answer it. It never captures any other tab.
• Watch creator adds that creator’s public handle to your watchlist.

5. Usage diagnostics (on by default, can be turned off)

When you are connected, the extension sends event names like popup_opened or clip_saved, the extension version, and a few small details such as your plan tier or which shortcut you used, with your Jucey sign-in. It never sends post content, authors, or URLs here. Our server currently checks these events and does not store them. Turn this off in Options → Privacy → “Share usage diagnostics”.

6. Public-content-only boundary

The extension does not request Chrome’s cookies permission, read LinkedIn or X session cookies, or send social-network credentials to Jucey or its processors.

Because LinkedIn does not expose private author-only impression analytics publicly, Jucey does not claim those numbers unless they come from a separate, explicit user-provided source. Public likes, comments, reposts, and visible view counts may still be used as labeled reach signals.

7. Permissions

• storage — saves your Jucey API token, your settings, and your consent choices locally in chrome.storage.local.
• scripting — adds the Jucey cup to supported tabs that are already open at install time, and refreshes your Jucey sign-in on a jucey.app tab. Limited to the host permissions below.
• alarms — runs an hourly refresh of the scoped Jucey API token.
• contextMenus — right-click → Save to JUCEY / Watch this author, only on the supported sites.
• sidePanel — shows creator research and chat in Chrome’s side panel.
• Host permissions: linkedin.com, x.com, twitter.com (legacy redirect to x.com), youtube.com, substack.com, and jucey.app. Nothing else.

8. Your rights

You can revoke the extension’s access at any time (Options → Reset extension data, or remove the extension entirely). For data deletion, account export, or any other GDPR / CCPA request, email dpo@jucey.app.
