In short: KeyFlips runs entirely in your browser. It does not send your data to us, we do not run any servers that receive it, and we never sell or share it. The only outside services KeyFlips talks to are Gumroad (to check your license), Keepa (with your own API key, if you add one), and Amazon Seller Central (with your own login, for the gating check).
What KeyFlips is
KeyFlips is a Chrome extension that adds estimated profit, ROI, maximum buy price, sales and listing-eligibility (gating) information to the Keepa Deals page at keepa.com.
Information KeyFlips handles
| Information | Why | Where it goes |
|---|---|---|
| Your settings (profit and ROI targets, fees, FBA/FBM choice, selected columns) | To calculate and display the badges the way you set them | Stored in your browser only (Chrome storage) |
| Your KeyFlips license key | To confirm you have an active subscription | Sent to Gumroad's license verification service; stored in your browser |
| License status returned by Gumroad (active, cancelled or ended, plan, and the email on the purchase) | To unlock or lock features | Stored in your browser only |
| Your Keepa API key (optional) | To get exact fees, prices and sales data | Sent only to Keepa's API; stored in your browser |
| Product identifiers (ASINs) and prices shown on the Keepa Deals page | To calculate profit and look up fees and gating for those products | Read in your browser; ASINs are sent to Keepa's API (if you added a key) and to Amazon Seller Central (for the gating check) |
| Gating results from Seller Central | To show ✅ / 🔒 / ⛔ on each product | Stored in your browser for up to 6 hours |
KeyFlips does not collect your name, address, payment details, browsing history, location, keystrokes, or the contents of any page other than the Keepa Deals table.
Amazon Seller Central
If the gating check is turned on, KeyFlips asks Seller Central whether your seller account can sell each profitable product. It does this from your own browser using the Seller Central login you are already signed in with. KeyFlips never sees, stores or transmits your Amazon password, and it does not read any other part of your Seller Central account.
Payments
Subscriptions are sold and processed by Gumroad. KeyFlips never receives or stores your card or payment information. Gumroad's handling of your purchase is covered by Gumroad's privacy policy.
