Milepost — Privacy Policy

Last updated: September 27, 2026

Milepost ("the app") is an iOS and Apple Watch app that records your runs, walks and bike rides: time, distance, pace, mile or kilometre splits, and the route you took. Recording needs no account. An optional friends feature lets you share the stats of your activities, and if you choose, the streets you covered, with people you accept. There are no ads and no analytics.

What stays on your phone

• Your activities — the start time, duration, distance, pace, splits, the GPS points that make up your route, and the title you give each one. These are saved in a database on your phone.
• Your settings — miles or kilometres, voice cues, whether you share with friends, and your Apple Health choices.

Routes, GPS points and splits never leave your phone, whether or not you use friends. The one exception is the optional Share streets with friends switch described below, which is off unless you turn it on.

Apple Watch

If you record an activity on your Apple Watch, the watch measures your heart rate and the calories you burn as well as your location, and sends the finished activity to your iPhone over Apple’s own encrypted link between your two devices. Nothing recorded on the watch is sent anywhere else. While a workout is running on the watch, your iPhone can show it and pause or end it; that also travels only between your devices.

Apple Health

Milepost can add your activities to Apple Health. This is off until you turn it on in You → Apple Health, and iOS asks your permission separately before anything is written.

• What is written — each activity as a workout: sport, start and end time, how long you were moving, distance, your splits as laps, and an estimate of the calories you burned. On Apple Watch, the heart rate and calories the watch measured are written too.
• Your route — a separate switch, and it is off by default. Turn it on and the GPS points of each activity are written to Health as well, so Health can draw your route.
• What is read — heart rate, calories, steps and running or cycling metrics recorded during your activities, so the app can show them, and your weight, so it can estimate calories more accurately. You can refuse any of these in Health and the app carries on without them.

Apple Health is a database on your own device. Everything Milepost writes to it or reads from it stays on your device. Health data is never sent to our server, never shared with your friends, and never used for advertising or analytics. Deleting an activity in Milepost also deletes the workout Milepost wrote for it.

Location

The app asks for location access when you press Start, and only then. While an activity is being recorded it reads your GPS position, including with the screen off, to measure distance and pace and to draw the route. Recording stops when you press Finish, and the app stops tracking your location. Once you have given permission, the map on the Record screen also shows your current position (the blue dot) while the app is open on that screen, even when nothing is being recorded; that dot is drawn by iOS on your phone and is not saved or sent to our server. Your location is never sent off the device by Milepost unless you turn on Share streets with friends.

Maps. The maps in the app are Apple Maps. To draw them, your phone downloads map tiles from Apple for the area on screen, which is usually around where you are. Apple handles those requests under its own privacy policy (apple.com/legal/privacy); Milepost does not send Apple your routes or activities.

The Record screen draws your past activities on the map from the routes saved on your phone: orange for streets you covered, darker each time you cover them again. That drawing is made on your phone.

Friends (optional)

If you choose Sign in with Apple to use friends, the following is stored on our server (Supabase, hosted in the United States) and linked to your account:

• Your account — the identifier Sign in with Apple gives the app. The app does not ask Apple for your email address, so no email address is stored.
• Your profile — the username you pick and an optional display name. Apple offers your name the first time you sign in; it is only used to suggest a display name and is not stored unless you keep it.
• Your friends — who you are friends with, requests sent and received, and people you have blocked.
• Shared activities — for each activity you save while sharing is on: sport, title, start time, distance and moving time. No route, map, GPS point or split.
• Shared streets — only if you turn on Share streets with friends (off by default): for each of your 500 most recent activities, the streets it covered, as the 15-metre squares of a map grid the route passed through, in order, plus its start date. The first and last 200 metres of every activity are removed on your phone before anything is sent, so where you start and finish (usually home) is not shared. No times, speeds, altitude or exact GPS points are sent. Friends see these streets in blue on their map, and in green where they covered the same street.
• Reports — if you report someone, who you reported and the reason you picked.

Who can see it

People you have accepted as friends see your username, display name, shared activities and any streets you share. Anyone signed in can find you by searching for your username, and sees only your username and display name. Blocking someone ends the friendship and hides you from them. We can see the stored data to run the service and to review reports; it is never sold, never used for advertising, and never shared with anyone else.

Deleting your data

• Delete any activity from the Block tab; if it was shared, it is deleted from the server too.
• Turn off Share streets with friends on the You tab to delete every street you have shared.
• Turn off Share activities with friends on the You tab to delete every activity and street you have shared.
• Delete account on the You tab deletes your account, profile, friendships, shared activities and shared streets from the server immediately. Activities on your phone stay until you delete them or the app.

Your rights

Wherever you live, you can ask to see a copy of the information our server holds about you, have it corrected, or have it deleted, and you can delete it yourself at any time from the You tab. We will answer within 30 days and will not treat you differently for asking.

• California (CCPA/CPRA) — you have the right to know, access, correct, and delete your personal information, and to opt out of its sale or sharing. We do not sell or share personal information for cross-context behavioral advertising.
• EEA and UK (GDPR / UK GDPR) — the friends feature processes your data to provide the service you signed up for (performance of a contract), and shared streets only with your consent, which you withdraw by turning the switch off. You also have the rights to data portability, to restrict or object to processing, and to complain to your local data-protection authority. Our server is in the United States.

To make a request, email the address below and include your Milepost username.

Children

Milepost is not directed at children under 13 and does not knowingly collect personal information from them.
