Zetlis (“we”, “us”, “our”) operates zetlis.com and provides an AI-powered eBay listing automation service. This policy explains how we collect, use, and protect your information.
To operate the service, process photos with AI, publish to eBay on your behalf, authenticate you, send service updates, and comply with legal obligations.
Photos are sent to Anthropic's API solely to generate listing content. We do not use your data to train AI models. We keep our copy of your photos only so your saved listings stay complete — see Data Retention below.
This section describes the Zetlis Photo Collector browser extension only. It is separate from how the zetlis.com website and the signed-in Zetlis app behave, which the rest of this policy covers. Photo Collector does not require a Zetlis account, and you can use it without having one.
The extension sends nothing to Zetlis
Photo Collector does not send the images you collect, the pages you visit, your browsing history, or any usage or analytics data to Zetlis or to any other service. It contains no analytics, no tracking, and no remote code. The images you select are saved by your own browser directly to your device.
What is stored, and where
The extension stores a small amount of data locally in your browser, using Chrome's extension storage: the product names and image addresses you have collected but not yet downloaded, your output preference (Original or JPG) and image-quality setting, and a record that you accepted the first-use notice. This never leaves your device. Removing the extension, or clearing your browser's extension data, deletes it.
Access to web pages
The extension has no standing access to any website. It reads a page only when you click its toolbar icon on that page, and only that tab — this is Chrome's “activeTab” model. It requests no host permissions and does not run in the background on the sites you browse. Its permissions are limited to acting on the tab you invoked it on, saving files you have chosen to download, and storing the local settings described above.
Network requests
When you download or convert an image, your browser fetches that image from the website hosting it, exactly as it would if you saved the picture yourself. Those requests go to that website, never to Zetlis. Visiting zetlis.com from a link in the extension is a normal visit to our website and is covered by the rest of this policy.
We do not sell your data. We share only with the service providers above, strictly to operate the service.
EU / GDPR
Access, correct, delete, restrict, or export your data. Withdraw consent. File a complaint with your local data protection authority.
US / CCPA
Know what we collect, delete your data, and opt out of data sale (we do not sell data).
To exercise any right, contact support@zetlis.com.
We use five HttpOnly cookies — ebay_token, ebay_refresh, ebay_oauth_state, ebay_username, and ebay_uid — required for eBay integration only. They are cleared when you disconnect eBay or delete your account. We do not use advertising or tracking cookies.
We use HTTPS, HttpOnly cookies, Supabase Row Level Security (RLS) to keep each account's data separate, and automatic clean-up of uploaded files that are no longer attached to any of your listings. Your stored eBay authorization credential is encrypted with AES-256-GCM before it is written, and its encryption key is kept outside the database in our hosting provider's environment configuration. No system can be guaranteed completely secure, but this means database access on its own does not reveal the credential.
Service is operated from the United States. EU data may be transferred to the US under standard contractual clauses with our service providers.
Service is not directed to users under 16. Contact support@zetlis.com if concerned.
We may update this policy from time to time. Continued use of the Service constitutes acceptance of the updated policy.
