Privacy policy

Updated October 27, 2026

This policy covers the Sellsavo browser extension and the website sellsavo.com. Contact: privacy@sellsavo.com.

What the extension processes

• Page content of supported marketplace and supplier sites you open — price, title, category, size and weight, ratings, search results. It is read inside your browser to calculate fees and is not sent anywhere.
• What you enter — your costs, prices, package sizes, saved supplier costs and settings. Stored in the extension's local storage on your computer only.
• License key — if you buy Pro, the key you enter is sent to Gumroad (api.gumroad.com) to check that it is valid. Gumroad processes payments as the merchant platform; see Gumroad's privacy policy.

What we don't do

• No account, no tracking, no analytics, no advertising identifiers.
• No browsing history is collected; the extension runs only on the sites listed in its permissions and never on checkout, sign-in or seller-console pages.
• No selling or sharing of data. We have no server that receives your data.

The website

sellsavo.com is a static site hosted on Vercel. It sets no cookies and has no analytics. Vercel may keep standard server logs (IP address, user agent) for security and operations. The calculator runs entirely in your browser; it remembers your last selected marketplace in local storage.

Your rights

Removing the extension deletes everything it stored. Since we hold no personal data about you apart from emails you send us, requests about those emails (access, deletion) can be sent to privacy@sellsavo.com. If you are in the EU/EEA or the UK you also have the right to complain to your data protection authority.

Changes

We will update this page and its date if anything changes.
