MileDial privacy

Last updated October 14, 2026. See what all my apps have in common.

MileDial hasn't been released yet. This page describes how it's being built and will be finalized before release.

MileDial builds your routes on your phone. Your location is used on your device and isn't sent to me.

What it stores

Your settings, such as your preferred distance and units, the runs you've finished, and map data for the regions you download.

Location

MileDial asks for your location only while you're using it. It uses it to start a route where you're standing, follow your progress, and tell you when you reach each mile or your turnaround. During a run it keeps tracking with the screen off; that still counts as using the app. It never asks for location "all the time".

Routes are worked out on your phone from OpenStreetMap data stored on the phone, so planning a route doesn't send your location anywhere.

Maps and search

The map you see is drawn by your phone's own map service: Apple Maps on iPhone and Google Maps on Android. To show it, your phone asks Apple or Google for map images of the area on screen, under their own privacy policies.

If you search for a place to start from, the search goes to Apple on iPhone or Google on Android in the same way. Using your current location or dropping a pin doesn't search.

The only other thing MileDial downloads is map data for the regions you choose. Those downloads don't include your location.

Notifications

Mile and turnaround alerts are local notifications created on your phone. Nothing is sent through a server.

Saving to Health

A future version will be able to save finished runs to Apple Health or Health Connect, if you turn it on. MileDial will only write to Health and won't read anything from it.

Where it's kept

On your phone: your settings and the history of your runs. MileDial doesn't sync between devices and isn't included in phone backups on Android. Deleting the app deletes its data.
