Privacy policy
LatLong Fill, a Google Sheets add-on by DullFix. Last updated: November 14, 2026.
What LatLong Fill accesses
- Only the spreadsheet you open it in. It uses Google's "current spreadsheet only" permission and cannot see your other files.
- It reads the address columns you tick, and writes Latitude, Longitude, Accuracy, Matched address and a hidden LatLong Fill key column into that sheet.
Where your addresses are sent
- Addresses that look like US addresses are sent to the US Census Bureau geocoder.
- Other addresses, and US addresses the Census can't match, are sent to Google's geocoding service through Google Apps Script.
- Each service handles the address under its own privacy terms. LatLong Fill sends nothing else from your sheet.
What we store
- A daily counter (today's date and how many addresses were found) in your own Google Apps Script user storage, to apply the free daily limit.
- We run no servers, use no analytics or tracking, and keep no copy of your addresses or results.
- We do not sell, rent or share any data, and we do not use it for advertising.
Google user data
LatLong Fill's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
Deleting your data
Delete the columns LatLong Fill added to remove its results. Uninstall the add-on from Extensions > Add-ons > Manage add-ons to stop all access. The daily counter is overwritten every day.
