SellerPulse Privacy Policy

Last updated November 8, 2026

SellerPulse is a browser extension for Amazon. This policy explains what it reads, what it keeps and what leaves your device.

What SellerPulse reads

The Amazon.com product page you have open: product title, ASIN, price, and any rating, Best Sellers Rank, category and weight the page shows. It reads these only on the pages it runs on, to do its job.

What SellerPulse keeps

Your calculation drafts and the costs you enter, your buy criteria and cost presets, scenarios you save to the Deal Sheet, daily usage counts, your plan status and, if you have Pro, your license key and what Polar last said about it. All of this stays in your browser's local extension storage on your device. The developer has no access to it.

What leaves your device

SellerPulse sends nothing to its developer. There are no accounts, analytics or trackers. All calculations run on your device.

The one exception is Pro: if you have it, your license key goes to Polar, as described under Payments below.

Payments

Pro is sold through Polar (polar.sh), our reseller and Merchant of Record: Polar runs the checkout, takes the payment and handles sales tax and VAT. SellerPulse never sees your card or bank details. Polar handles your purchase data under its own privacy policy.

After you buy, Polar gives you a license key. When you paste it into SellerPulse, the key is stored in your browser and sent to Polar's license API (api.polar.sh) to activate it for this browser, with a label such as "SellerPulse · Chrome · date", and then every few hours to check that your subscription is still active. Polar answers with the key's status, the end date of the plan and the email address of the purchase; SellerPulse keeps that answer on your device to show which account Pro belongs to. If Polar can't be reached, Pro keeps working for up to 72 hours. Removing the key in SellerPulse frees this browser's activation. Billing, invoices and cancellation are in your Polar account.

What SellerPulse never does

• It doesn't sell or share your data.
• It doesn't use your data for advertising, credit decisions or anything unrelated to its purpose.
• It doesn't run remote code.
• SellerPulse never buys, lists or changes anything on Amazon.

Your control

You can export or delete your saved records in the SellerPulse workspace. Removing the extension deletes everything it stored in your browser.

Changes and contact

If this policy changes, the date above will change too. Questions: a@pr.tools
