The extension has no server of ours and no analytics. It talks to Costco to read your own receipts, to Google Drive only if you connect it, and to Lemon Squeezy only to check a Premium license. Price adjustments are suggestions; Costco decides. Buck Fifty is independent software. It is not affiliated with, endorsed by or sponsored by Costco Wholesale Corporation.
