Plain-English summary: Lux Handoff injects a prompt into your active Claude session to generate a structured handover summary. Your Claude conversations, chat history, and session content stay entirely on your device — we never see them. We contact our licence server (Supabase) only at three specific moments to manage your licence. See Section 2 for details.
This privacy policy covers Lux Handoff, the Chrome extension published by Lux Wealth Group (ABN 94 281 418 234). It describes exactly what data the extension collects, what it sends to our servers, and what it does not.
1. What stays on your device
The following data is generated, stored, and used only on your device. None of it is transmitted to Lux Wealth Group, Supabase, or any third party.
- Your Claude prompts, replies, and chat history on claude.ai
- The session summary generated by Claude during a handover
- Exported PDF, TXT, and Markdown files (saved to your Downloads folder)
- Your Resume Context (stored in browser local storage for clipboard copy)
- The trial start timestamp if you are on the 7-day free trial
- The "welcome screen seen" flag
2. What we send to our licence server
To enforce licence validity and device limits, the extension contacts our backend hosted on Supabase (fqnsmqzznmouzcotpjxs.supabase.co) in three specific situations only:
| When | What we send | Why |
|---|---|---|
| You activate a key | Licence key, email address, a random device ID generated locally on first install | To verify the key is valid, the email matches the one used at checkout, and the device limit has not been reached |
| Every 24 hours (background heartbeat) | Licence key, random device ID | To confirm your key has not been revoked and your device slot is still bound |
| You click "Remove key" | Licence key, email, random device ID | To free a slot so you can activate on another device |
Your IP address is incidentally visible to our Supabase server during these requests, as with any HTTP connection. We do not log or store your IP address beyond what Supabase retains in its infrastructure logs (typically 7 days — see Supabase's privacy policy).
3. What we do NOT do
- We do not read, log, or transmit your Claude prompts, replies, or conversation content
- We do not use analytics or telemetry of any kind
- We do not track which sites you visit (the extension only runs on
claude.ai) - We do not sell your data to third parties
- We do not use cookies, localStorage on the open web, or browser fingerprinting beyond the single random UUID described in Section 4
- We do not send any portion of your Claude conversations to our servers under any circumstances
4. The device ID we generate
On first install, Lux Handoff generates a random UUID (e.g. 3f8c4e2a-...-9d1b) using your browser's built-in crypto.randomUUID() function. This UUID is stored in your browser's local extension storage and sent to our licence server during activation, heartbeat, and deactivation.
This UUID is not derived from any of your device's properties, identifiers, hardware, network, or personal information. It exists only to distinguish "device A" from "device B" for the device-limit feature. If you uninstall and reinstall the extension, a new UUID is generated.
5. Email address
The email you provide at activation is matched against the email you used to purchase the licence (via Stripe). It is stored in our Supabase database alongside your licence key and device ID. We use it only to verify you own the licence at activation and to send licence-related support emails. We do not add you to any marketing list. We do not share your email with third parties.
6. Payments
Payments are processed by Stripe. Lux Wealth Group does not see, store, or transmit your credit card details. Stripe shares your payment email and a transaction ID with us, which we use to issue your licence key.
7. Data retention and deletion
Your licence record (key, email, device ID) is retained while your licence is active. If you wish to permanently delete your data, email support@luxwealthgroup.com.au and we will delete your record within 30 days. Note that this revokes your licence — you will lose access to the extension's paid features.
8. Children's privacy
Lux Handoff is not directed at children under 13 and we do not knowingly collect data from children.
9. Changes to this policy
If we change this policy in a way that materially expands our data collection, we will update the "Last updated" date at the top of this page and notify existing licence holders by email at least 14 days before the change takes effect.
