Privacy policy
1. Product CSV processing
Shopify CSV/XLSX validation, two-file Compare, Shopify price preparation, BigCommerce precheck, Wix legacy CSV precheck/Compare and WooCommerce or supplier CSV draft conversion read selected files in this browser tab and Web Workers. Source files, generated copies, mappings and previews stay local. Catalog files are not uploaded to a Catalog Precheck server or sent to a store API.
2. Your controls
Clear a file or clear both files to remove the relevant working copies and results from this tab; refreshing also clears the session. Catalog data is not saved in browser persistent storage. Downloaded reports remain wherever you save them, and your original files are not changed.
3. Website operations
Local validation, limited Compare and price preparation need no account or payment. The website may process access logs needed for secure operation. When Google Analytics is configured, Catalog Precheck sends only fixed event names for task start, preview/check completion, failure, Compare limits, price-copy generation and opening Compare; no custom parameters. Analytics/ad storage, Google signals, ad personalization and automatic page views are disabled. CSV content, filenames, Handle, SKU, prices and field values are not sent.
4. Optional account and payment data
When paid Compare is enabled, Google and Supabase handle sign-in; Catalog Precheck stores your user ID, email, order status, credit balance and usage time. PayPal handles checkout and provides order, capture, refund and dispute identifiers. CSV content, filenames and report values are not sent with these records.
