Privacy policy.
marker is a run tracker that keeps your runs on your phone. We do not have accounts, we do not have a server that stores your runs, and we cannot see where you ran or what you wrote in your journal.
We do collect a small, fixed set of anonymous usage events so we can tell which parts of the app people actually use. Those events never include your location, your route, or anything you typed.
What stays on your device
Everything that makes up a run is stored locally on your iPhone:
GPS coordinates recorded while a run is in progress, and the route trace built from them
Distance, duration, date, and time of day
Neighborhood and place names resolved for the route
Weather conditions recorded at the time of the run
Notes you write on a run
Shoes you set up and their mileage
Your settings and preferences
None of this is transmitted to Strictly Business Group, LLC, and none of it is stored on any server we operate. We operate no server.
If you delete the app, this data is deleted with it.
Permissions the app asks for, and what it does with them
Location (while using the app)
Required to measure a run. The app records position fixes during an active run and uses them to compute distance and draw your route. Location is not collected when a run is not in progress, apart from one coarse fix used to show local weather on the home screen. See Third-party services for the limited cases where coordinates leave the device.
Motion & fitness
The gyroscope is used to tilt the water level inside each circle so it reads as level with the world. This is processed live on the device and is never recorded or transmitted.
Apple Health (optional, off by default)
If you turn it on, marker writes each completed run to Apple Health as a Workout, including distance, elevation, and the route. That data goes to Apple Health on your device under Apple's privacy controls — it does not come to us. You can revoke this at any time in the iOS Health app.
Calendar (optional, off by default)
If you turn it on, marker adds a short entry for each run to your calendar. It requests write-only access and never reads your existing events.
iCloud sync (optional, off by default)
If you turn it on, your runs sync between your own devices through your personal iCloud account using Apple's CloudKit private database. That data lives in your iCloud account, governed by Apple's privacy policy. Strictly Business Group, LLC has no access to it.
Third-party services
Three services receive data from the app.
Open-Meteo (weather)
To show conditions for a run, the app sends a latitude and longitude to open-meteo.com and receives back a temperature and a weather code. No identifier, account, or device information is attached to the request. See Open-Meteo's terms and privacy policy.
OpenStreetMap / Overpass API (neighborhood names)
To label the places you run through, the app downloads a coarse map tile covering roughly a 22-kilometer region and caches it on your device. It requests one tile per region, once, and matches your route against it locally — individual route points are never sent. Requests go to public Overpass API mirrors.
Apple's geocoder
As a fallback when a neighborhood cannot be resolved from the cached map data, the app asks Apple's reverse-geocoding service for a place name near a sampled point. This is handled by iOS under Apple's privacy policy.
Mixpanel (usage analytics)
Described in full in the next section.
Analytics
We use Mixpanel to understand how the app is used in aggregate — which screens people reach, whether onboarding gets finished, whether a run gets saved or discarded. There is no advertising SDK in this app, no IDFA, and no cross-app or cross-site tracking.
What we send:
A fixed list of events: app opened; onboarding steps and completion; permission results; run started, completed, saved, discarded, or deleted; screens viewed; notes added; shoe setup actions; share-sheet actions; settings changed.
Properties attached to those events: total distance and duration of a completed run, the number of circles, the counting mode and cadence, the number of neighborhoods resolved, and which setting changed to which value.
Your current setup as it stands: counting mode, cadence, whether chimes are on, whether Health, iCloud, and calendar are enabled, share defaults, location permission status, total runs saved, and whether a shoe is active.
Standard information the Mixpanel SDK collects automatically: a randomly generated identifier for the installation, device model, operating system version, app version, and the IP address of the request, from which Mixpanel may derive an approximate city or region. We do not use that identifier to look you up and it is not linked to your name, email, or any account.
What we never send: GPS coordinates, routes, neighborhood or place names, journal notes, shoe names, photos, contacts, or the contents of anything you share.
The current version of the app does not include an in-app analytics opt-out. If you would prefer not to send usage data, you can block the app's network access to Mixpanel at the network level, or write to us at the address below and we will delete the data associated with your installation if you can identify it.
Mixpanel processes this data on our behalf as a service provider. See Mixpanel's privacy policy.
Sharing a run
When you share a run image, the app renders it on your device and hands it to the iOS share sheet. Where it goes from there is up to you and is governed by whatever app or service you send it to. We are not in that path and do not receive a copy.
How long data is kept
Run data stays on your device until you delete a run or delete the app. If iCloud sync is on, deleting a run removes it from your other devices too.
Analytics events are retained by Mixpanel under our account's retention settings, currently up to 5 years, and are stored in the United States.
Your choices and rights
Location: revoke in iOS Settings → Privacy & Security → Location Services. The app cannot measure runs without it.
Health and Calendar: revoke in iOS Settings, or turn them off inside marker.
iCloud sync: turn off inside marker; you can also manage app data in iOS Settings → your name → iCloud.
Delete your data: delete individual runs in the app, or delete the app to remove all of it.
Depending on where you live — including the EU/UK under GDPR, and California under the CCPA/CPRA — you may have the right to request access to, correction of, or deletion of personal information we hold, and to object to certain processing. Because we hold no account data and cannot connect an installation to a person, the practical scope of this is the analytics data described above. Write to us and we will do what we can to honor the request.
We do not sell or share personal information, and we do not use it for targeted advertising.
Children
marker is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us information, contact us and we will delete it.
Changes to this policy
If we change how the app handles data, we will update this page and move the "Last updated" date. Material changes will also be noted in the app's release notes.
