UpInbox by UpGPT

Privacy Policy

Effective date: March 20, 2026  ·  Version 1.0

This Privacy Policy describes how GALAXZ HOLDINGS INC, doing business as UpGPT (“we”, “us”, or “our”), handles your information when you install and use the UpInbox Chrome Extension (“UpInbox” or the “Extension”).

We built UpInbox on a local-first, minimal-data principle: the vast majority of processing happens on your device, and we only touch our servers when strictly necessary to deliver the service.

1. What UpInbox Does

UpInbox is a free Gmail productivity extension. It reads your email metadata (sender, subject, date) to classify messages into categories such as newsletters, promotions, and receipts. It then lets you bulk-archive, apply Gmail labels, or set up auto-filter rules — all from a sidebar panel inside Gmail.

2. Data We Collect

2a. What UpInbox accesses from Gmail

UpInbox uses the Gmail API under your explicit OAuth 2.0 authorization to:

2b. What is NOT collected

The following data is never transmitted to UpGPT servers under any circumstances:

2c. What we store server-side

We only store the following on our servers (Supabase, hosted in the US):

3. What Stays Local on Your Device

The following data is stored exclusively in your browser’s IndexedDB and chrome.storage. It never leaves your device:

4. AI Processing

4a. How email classification works

UpInbox uses a three-tier AI processing model:

4b. Auto-Draft feature

If you use the Auto-Draft feature (Plus/Pro), draft generation requires reading the email thread to generate a contextual reply. Thread content is sent to the UpGPT AI proxy for this purpose only and is immediately discarded after generating the draft. Drafts are stored in your Gmail only — not on our servers.

5. Third-Party Services

6. Google API Limited Use Disclosure

UpInbox’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically:

7. Data Retention and Deletion

8. Your Rights Under GDPR and CCPA

8a. GDPR (European Economic Area and UK residents)

If you are in the EEA or UK, you have the following rights under the General Data Protection Regulation:

Our legal basis for processing your data is performance of a contract (to provide the Extension service) and legitimate interests (anonymous usage analytics to improve the product). We do not rely on consent as the basis for processing required to operate the service.

To exercise any GDPR right, email privacy@upgpt.ai. We will respond within 30 days. You also have the right to lodge a complaint with your local supervisory authority.

8b. CCPA (California residents)

Under the California Consumer Privacy Act, California residents have the right to:

To make a CCPA request, email privacy@upgpt.ai. We will verify your identity and respond within 45 days.

9. Security

UpInbox uses Chrome’s built-in identity system (chrome.identity) for OAuth. Your Gmail access token is managed by Chrome — UpInbox never stores it. All connections to UpGPT servers use HTTPS/TLS 1.2+. BYOK API keys are stored in chrome.storage.local which is sandboxed to the Extension and inaccessible to other extensions or websites.

10. Children’s Privacy

UpInbox is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has provided us with personal information, contact us at privacy@upgpt.ai and we will delete it promptly.

11. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be communicated by updating the effective date above and, where possible, via the Extension’s update release notes. Continued use after the effective date constitutes acceptance of the updated policy.
