Your data is 100% yours. Files are read in your browser and never uploaded or stored.

We only read three things: who gave, when, and how much. Never names or contact details leave your device.

Nothing to read yet

Add a .xlsx, .xls, or .csv export of your donor gift history to see your number.

How This Works

We look only at loyal repeat donors (two or more gifts in different periods) who gave before your chosen window but not since. We total their lifetime giving to your organization. The math runs on anonymized totals, never on names or emails.
