Privacy

LabelStack is a static web app. Barcode values, product names, SKUs, FNSKUs, uploaded CSVs, logos, and exported PDFs are processed with JavaScript in your browser. They are not sent to our servers because there is no upload endpoint for them. That is a product decision, not a slogan: open the network inspector while you export.

On this device

Template and theme preferences may be stored in localStorage on this device so the next visit opens the same Avery size. That store does not include your inventory rows. Closing the tab drops the working table from memory unless you downloaded a PDF or ZIP yourself.

Analytics and ads

Google Analytics (measurement ID G-G9PEDMQ1BC) records page views and named tool events such as “export PDF.” It is configured not to receive barcode text, file names, or CSV contents. Advertisements may be served by Google AdSense (publisher ca-pub-9456541586301398) after the site is accepted into the publisher network. Google may set cookies and collect typical analytics and ad-request data (page URL, IP, user agent, coarse location). This app does not pass barcode values, CSVs, or inventory to Google.

You can block ads and analytics in the browser; generation and export still work. Ads never appear on an exported PDF and never cover the download control.

Some product recommendations use Amazon Associate links. If you buy through those links, LabelStack may earn a commission. The click goes to Amazon; we do not attach barcode values, CSVs, or inventory to it.

Email

If you write to contact@labelstack.app, we receive whatever you put in the message. Do not attach catalogs. We keep mail long enough to answer and to correct a guide; we do not add addresses to a marketing list because there is not one.
