Customer Database
Add your customers, search and sort the list, and download it as a CSV whenever you want. It all stays in this browser: nothing is uploaded anywhere.

Where this list actually lives
Every contact you add is saved only in this browser’s local storage, on this device: nothing is sent to a server, because this tool doesn’t have one. That also means the list lives in this browser on this device only. If you switch browsers or computers, it won’t follow you unless you bring it yourself. Download the CSV as a backup whenever the list matters, and if you ever want the data gone, clearing this site’s data from your browser removes it for good.
What the two downloads are for
“Download contacts” exports everyone currently in your list as a CSV file, with a Name, Company, Email, Phone, and Notes column, ready to open in Excel or Google Sheets. “Download empty template” skips the tool entirely and gives you just that header row, for when you’d rather type contacts straight into a spreadsheet from the start.
A list, not a CRM
This tool keeps names, contact details, and a notes field: nothing tracks deals, pipelines, or communication history. If that’s what you actually need, this is a place to start collecting who your customers are, not the place to run the relationship from.

Take it further, in a spreadsheet
This list stays a list: names, contact details, and notes, nothing more. The Small Business Finance Kit links the same kind of contact to every invoice you send them, so you can see what one client has actually paid you over time.
