Privacy Policy
In short: MileBack uses your location and motion data to detect and record your drives. Your trip history is stored on your iPhone. We don't sell your location data, we don't require an account, and you can delete your data at any time.
1. Who we are
MileBack ("MileBack", "we", "us") is operated by Balanced Answers Unipessoal LDA, Portugal. We are the controller of the personal data described in this policy. You can reach us about privacy at info@mileback.app.
2. What we collect
MileBack does not ask you to create an account, and we do not ask for your name, email or phone number to use the app.
| Data | Why | Where it's kept |
|---|---|---|
| Precise location, including in the background, while a drive is being recorded | To detect drives and measure the route and distance | Processed and stored on your iPhone |
| Motion & Fitness activity (e.g. "driving", "walking") | To tell when you start and stop driving and to leave out non-driving trips | Processed on your iPhone; not stored as history |
| Trip records: start and end time, start and end coordinates, route, distance, addresses, purpose (business/personal), notes | To build your mileage log and reports | Stored on your iPhone |
| Start and end coordinates of each trip | Sent to Apple's mapping service to turn them into street addresses | Processed by Apple under its privacy policy |
| Settings you enter: working hours, labelled places, vehicle make, model, year, license plate and nickname | To classify trips and label your reports | Stored on your iPhone |
| Subscription data: an anonymous app user ID, product purchased, trial and renewal status, country | To manage your subscription and unlock features | Apple and RevenueCat |
| Device and usage data: device model, iOS version, app version, app events (e.g. onboarding completed, report exported), crash data, and an app-specific device identifier | To measure and improve the app, fix bugs, and measure advertising | Our analytics and attribution providers |
| Advertising identifier (IDFA) | To measure our ad campaigns — only if you allow tracking | Our attribution and advertising partners |
| Support messages you send us | To answer you | Our email provider |
We do not collect your payment card details — Apple handles all payments. We do not upload your trip history or routes to our own servers.
3. How we use your data
- To detect, record, classify and display your drives, and to generate mileage reports you choose to export.
- To calculate estimated deduction values using the IRS standard mileage rate.
- To provide, manage and verify your subscription and free trial.
- To understand how the app is used, diagnose problems and improve features.
- To measure the effectiveness of our advertising (with your permission where required).
- To respond to support requests and to comply with legal obligations.
We do not use your trip history or location to target ads to you, and we do not build a profile of where you go.
4. Legal bases (EEA and UK users)
- Contract — to provide the app features and subscription you asked for.
- Consent — for location and Motion & Fitness access (given through your iPhone's permission prompts) and for tracking through Apple's App Tracking Transparency. You can withdraw consent at any time in your iPhone Settings.
- Legitimate interests — for app analytics, crash reporting, security and fraud prevention, balanced against your rights.
- Legal obligation — where we must keep or disclose records by law.
5. Who we share data with
We share personal data only with service providers that help us run MileBack, under contracts that limit how they may use it:
- Apple — App Store purchases, subscriptions, and address lookup (geocoding).
- RevenueCat — subscription management.
- Analytics and attribution providers (such as AppsFlyer) — app usage measurement and ad attribution.
- Advertising platforms (such as Meta) — measuring the results of our ads, only where you have allowed tracking.
- Email and hosting providers — to handle support email and host this website.
We may also disclose data if required by law, to protect our rights or users' safety, or as part of a merger, acquisition or sale of assets (in which case this policy will continue to apply). We never sell your location data or trip history.
6. Tracking and advertising
MileBack asks for permission through Apple's App Tracking Transparency before accessing your device's advertising identifier. If you tap "Ask App Not to Track", we do not access it. You can change this at any time in Settings → Privacy & Security → Tracking.
7. How long we keep data
- Trip history and settings stay on your iPhone until you delete them in the app or delete the app. Deleting the app removes them permanently — export a report first if you need your records.
- Analytics and attribution data is kept for as long as needed to operate and improve the app, and no longer than 24 months.
- Subscription records are kept for as long as you have a subscription and afterwards as required by tax and accounting laws.
- Support emails are kept for up to 24 months after the conversation ends.
Keep your own copies of your mileage reports. Tax authorities may ask you to produce records for several years, and because your trip history is stored on your device, we cannot recover it for you.
8. Your rights
Depending on where you live, you may have the right to access, correct, delete or port your personal data, to object to or restrict certain processing, and to withdraw consent. Because MileBack has no accounts, most of your data is already under your control on your iPhone.
To make a request, email info@mileback.app. See Delete my data for step-by-step instructions. We respond within one month. If you are in the EEA or UK, you can also complain to your local data protection authority — in Portugal, the Comissão Nacional de Proteção de Dados (CNPD); in the UK, the Information Commissioner's Office (ICO).
9. U.S. state privacy rights
If you live in California or another U.S. state with a comprehensive privacy law, you have the right to know what personal information we collect, to delete it, to correct it, and to opt out of the "sale" or "sharing" of personal information for cross-context behavioral advertising. We do not sell personal information for money. Where you allow tracking, sending device identifiers to advertising partners to measure ads may be considered "sharing" — you can opt out by denying or turning off tracking as described in section 6, or by emailing us. Precise location is used only to provide the app's core features. We will not discriminate against you for exercising your rights.
10. International transfers
We are based in the European Union and some of our providers are in the United States. Where data is transferred outside the EEA or UK, we rely on adequacy decisions (including the EU–U.S. Data Privacy Framework where the provider is certified) or the European Commission's Standard Contractual Clauses.
11. Security
Trip data is protected by your iPhone's built-in security and encryption. Data held by our providers is protected with industry-standard safeguards. No system is perfectly secure, so please keep your device protected with a passcode.
12. Children
MileBack is intended for adults who drive for work. It is not directed to anyone under 18, and we do not knowingly collect data from children. If you believe a child has used the app, contact us and we will delete any related data we hold.
13. This website
mileback.app does not use advertising cookies or trackers. Our hosting provider keeps standard server logs (such as IP address and browser type) for security. Fonts are loaded from Google Fonts, which receives your IP address when the page loads.
14. Changes and contact
We may update this policy. If changes are significant, we'll let you know in the app or on this page before they take effect. The date at the top shows when it was last updated.
