Privacy Policy
Effective date: 22 October 2026
PrepLabel (“the extension”) is a Google Chrome extension that creates barcode and QR code labels from spreadsheet files you choose.
Data the extension processes
- Your spreadsheet. The contents of the file you upload (typically product SKUs or FNSKUs, product titles and quantities) are read inside your browser to draw the labels.
- Your settings. Label layout choices you make (Pro plan).
- Your license (Pro plan only). If you buy PrepLabel Pro and enter your license key, the extension sends the key and the product ID to Gumroad’s license service (api.gumroad.com) to confirm the purchase, when you activate it and about once every 7 days afterwards. Gumroad’s reply includes the purchaser email address and purchase status.
What stays on your computer
Your spreadsheet and product data are processed entirely in your browser. They are never uploaded, sent to a server, or shared with anyone, including the developer and Gumroad.
The extension stores, in Chrome’s local extension storage on your device only: the products and settings needed for your five most recent print jobs (older ones are deleted automatically), your layout settings, and, if you activated Pro, your license key, purchaser email and the dates of the last license check. Removing the extension deletes this data. It is not synced to your Google account.
What is not collected
No analytics, tracking, advertising identifiers, cookies, or browsing history. The extension does not read or change any website. Free users who never enter a license key make no network requests.
Payments
Purchases are handled by Gumroad, which processes payment and purchase details under its own privacy policy. The developer receives standard sale information from Gumroad, such as the buyer’s email address, as with any Gumroad sale.
Third-party code
The extension includes open-source libraries that run locally and make no network requests: SheetJS (reading spreadsheets), JsBarcode (Code 128 barcodes), qrcode-generator (QR codes) and the IBM Plex font.
Limitations
Anyone with access to your Chrome profile can access the extension’s local storage, as with other browser data. No software can be guaranteed free of defects.
Independence
PrepLabel is an independent tool. It is not affiliated with, endorsed or sponsored by Amazon. Amazon and FBA are trademarks of Amazon.com, Inc. or its affiliates.
