eBay Research

Privacy policy

Effective 24 October 2026. This policy covers the eBay Research Chrome extension and the cloud copy service behind it (together, "eBay Research").

In short

What is stored on your computer

The extension saves, in your browser's own storage, the runs you make: the eBay listings and shops it read (titles, prices, sold counts, seller names, links), the AliExpress products it found for them, your settings, the Watchlist you choose, and an activity log of what the run did. This stays on your computer. Removing the extension erases it.

What is copied to the cloud (only if cloud copy is on)

The cloud copy is on by default in the builds we give to users. It sends to our server, which runs on Cloudflare:

It never sends your eBay or AliExpress logins, cookies, payment details or your browsing history.

Linking your Google account

You can link the Google account your Chrome is signed in to, with one button. Google shows its own consent box and we ask for one permission only: to see your email address. We receive and store:

We use them for one purpose: when you reinstall the extension or use another computer, Google tells our server which account you are, so your saved data can be attached to the new installation. We also show the email to the person who runs the service so they can tell users apart when giving support. We do not use it to send marketing, and we do not read anything else from your Google account.

eBay Research's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Who can see your data

How long we keep it, and deleting it

Saved data is kept until you delete it. When you delete a run in the dashboard, it is deleted in the cloud copy as well. To have everything we hold about you deleted, including your Google email, write to support@nichlist.com from the email address you linked. We delete it within 30 days. Data on your own computer is deleted by removing the extension.

Security

Data travels over HTTPS. The server accepts a request only with your key, and only for your own data. A new installation can reach your data only by proving, through Google, that it belongs to the same Google account you linked. Google's sign-in tokens are checked with Google and are not stored.

Children

eBay Research is a business tool and is not meant for children.

Changes

If this policy changes, the date at the top changes with it. We will tell users about any material change.
