MileageSync Privacy Policy

Overview

MileageSync (“the app”) is an automatic mileage tracker operated by DeviceBytes LLC (“we,” “us”). It records your drives, calculates distance and duration, and builds mileage and tax-deduction reports.

The short version:

• There is no account. You never sign up or sign in, and we do not run servers that receive your trips.
• Your trip history stays on your device. Trips, routes, vehicles, clients, odometer readings, tolls, parking, and reports are stored in a database on your phone.
• Two outside services receive limited data: Mapbox, to snap recorded routes to roads and look up addresses, and Google AdMob, to show ads (unless you buy Remove Ads).
• We do not sell your data.

Information the app uses

Location (including background location). With your permission, MileageSync reads your device’s precise location, including while the app is closed, to detect when a drive starts and ends and to record the route in between. Location points, trip start and end points, and addresses are saved on your device. Background location is used only for trip tracking, never for advertising. You can pause or turn off automatic tracking in the app, or revoke location permission in your device settings at any time.

Motion and activity data. With your permission, the app reads your device’s motion or activity-recognition signals (for example, whether the phone appears to be in a vehicle, walking, or still). This helps tell driving apart from other movement and decide when a trip has ended. The data is processed on your device and is not stored or sent anywhere.

Information you enter. Trip categories, purposes, notes, clients, vehicles, license plates, odometer readings, tolls, parking amounts, and mileage rates are stored on your device only.

Diagnostics. The app keeps a short local log of tracking events (for example, when a trip started or a background task ran) so problems can be diagnosed. This log never leaves your device unless you choose Report a bug, which opens an email to us that already includes your app version, device platform, and recent log entries. You can review or edit that email before sending it.

Notifications. Trip and tracking notifications are generated on your device. MileageSync does not use a push notification service and does not collect a push token.

Purchases. The optional Remove Ads purchase is processed entirely by Apple (App Store) or Google (Google Play). We never see your payment details; the app stores only whether the purchase has been made.

Services that receive data

Service	Purpose	Data involved
Mapbox	Snapping recorded routes to roads (map matching), detecting toll roads, and looking up street addresses (reverse geocoding)	Location coordinates and timestamps from your trips, sent without any name, account, or contact details
Google AdMob	Showing banner ads and an occasional ad before exporting a report	Device advertising identifier (only if you allow tracking; see below), IP address, device and app information, and ad interaction data

Mapbox processes this data under the Mapbox Privacy Policy. Google processes ad data under Google’s Privacy Policy and How Google uses information from sites or apps that use its services.

Advertising and tracking

The free version of MileageSync shows ads from Google AdMob.

• iPhone: the app asks for permission (App Tracking Transparency) before your device’s advertising identifier (IDFA) can be used. If you decline, AdMob shows non-personalized ads and does not receive the IDFA. You can change this later in Settings → Privacy & Security → Tracking.
• Android: you can reset or delete your advertising ID, or opt out of ad personalization, in your device’s Google settings.
• Remove Ads: buying Remove Ads stops the app from loading ads, so no data is sent to AdMob.

Your trip locations and trip history are never shared with advertisers.

Exports and backups

When you export a report (CSV or PDF) or create a backup file, the file is created on your device and handed to the share sheet. It goes only where you send it, such as email, a cloud drive, or another app, and that destination’s own privacy policy then applies. Restoring a backup reads the file you choose and does not contact our servers.

What we do not do

• We do not sell your personal information.
• We do not require an account or collect your name, email address, or phone number (unless you email us).
• We do not upload your trip history to our own servers.
• We do not use analytics or crash-reporting services that send data off your device.

Data retention and deletion

Because your data lives on your device, you control how long it is kept:

• Delete individual trips in the app.
• Delete everything at once with Settings → Data privacy → Delete local data.
• Uninstalling the app removes its database from your device.

Emails you send us, including bug reports, are kept only as long as needed to respond and to keep reasonable support records. Data processed by Mapbox and Google is retained under their policies.

Security

Trip data is stored in the app’s private storage on your device, protected by your operating system’s app sandboxing and your device lock. Requests to Mapbox and AdMob are sent over encrypted HTTPS connections. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.

Children’s privacy

MileageSync is a tool for drivers and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, contact us and we will delete it.

Your rights

Depending on where you live (for example, California or the EEA/UK), you may have rights to access, correct, or delete personal information, or to object to certain processing. Most MileageSync data never reaches us, so you can use those rights directly in the app with the tools above. For anything we do hold, such as support emails, contact us. For advertising data, you can also use the controls described under Advertising and tracking. Where EEA/UK law applies, our legal bases are your consent (location, motion, and ad tracking permissions) and our legitimate interest in operating and supporting the app.

Changes to this policy

We may update this policy as the app changes. Updates will be posted on this page with a new “Last updated” date. If a change materially affects how your data is handled, we will also mention it in the app’s release notes.
