The add-in runs inside Excel on your own computer. The addresses you calculate go to one place, Google, using a key that belongs to you, and the only thing that ever reaches a server of ours is the license check. This page is the plain-words version.
The formal document is the Distance Calculator Privacy Policy.
What goes to Google #
When you run a calculation, the add-in reads the address or coordinate values from the columns you selected and sends each start and end pair to the Google Maps Platform to get the distance and the travel time. Those requests go directly from Excel to Google under your own Google Maps API key, so the usage runs on your Google account and the results are written straight back into your worksheet.
Google handles those addresses under the Google Privacy Policy. The add-in reads only the range you picked for the calculation; the rest of the workbook is never read and never transmitted.
What ever reaches us #
- The license check: your license key, an anonymous installation identifier (a random value generated on your device, not derived from your hardware) and the add-in version. Never addresses, results or workbook contents.
- Nothing else. There is no analytics, no advertising, no tracking and no automatic error reporting.
A record of the last successful check stays on your device so the add-in keeps working for a 7 day offline grace period when the license server cannot be reached.
What stays on your device #
Your license key, your Google Maps API key and your settings live only in your per-user Office add-in storage. Your Google Maps API key is never sent to us; it is used only to talk to Google. The worksheet formulas also keep a local cache of up to 1,000 recent inputs and results in that same storage, so recalculating a workbook does not re-query Google. That cache never leaves your device either.
Clear the keys in Settings, or remove the add-in, and all of it is gone.
If you send a support message #
Error messages are shown in the add-in only. You can copy a short diagnostic report (add-in version, Excel version, recent error messages, never your addresses or your keys) and include it yourself when you write in. Nothing is transmitted unless you send it.
