Browser Extension Privacy

Introduction

This policy explains how the Resell Reserve Sync browser extension handles your data. The extension connects your own logged-in Vinted account to your Resell Reserve CRM so your sales, purchases, listings and messages stay up to date without manual entry.

The key principle: our servers never log in to Vinted. All Vinted reads happen locally in your browser, on your own session. This policy covers the extension specifically — our general Privacy Policy covers the wider Service.

1. What the extension accesses

When you start a sync, the extension reads — using your existing browser session on Vinted — your own:

• Orders — items you have sold and bought - • Listings — your active and past listings - • Message threads — your Vinted conversations - • Account identity — your Vinted user ID and username, used only to confirm the extension is reading your own account

Permissions explained: The extension requests cookies access to read your existing Vinted login session locally, and storage to remember your last sync status. Host access to Vinted domains lets it fetch your own data from the regional marketplace you sell on.

2. How the data is used

The extension sends this data to your Resell Reserve account so the CRM can calculate net profit, track stock and organise your reselling activity. Data is sent over an encrypted connection (HTTPS/TLS) to your own account on app.resellreserve.co.uk.

The extension is single-purpose: it exists only to sync your own Vinted account data into your own CRM. It is not used for advertising, profiling, or any other purpose.

3. What we do NOT do

• We never receive or store your Vinted password. - • Our servers never log in to Vinted. All Vinted reads happen locally in your browser, on your own session. - • Your Vinted session cookies are never transmitted to our servers; they are used only locally to fetch your own data. - • We do not sell, rent, or share your data with third parties for their marketing. - • We do not use your data for advertising, creditworthiness or lending decisions.

4. Local storage

The extension stores the time and item counts of your last sync in your browser's local storage so the popup can show sync status. This information never leaves your device.

5. Data retention and deletion

Synced data lives in your Resell Reserve CRM account. You can delete it at any time from within the app (Settings → Clear synced data), or by deleting your account. Removing the extension stops all future syncing immediately.
