Privacy Policy

Stepper Pro · Last updated: September 16, 2026 · Version 1.0

1. Who we are

Stepper Pro (hereinafter, "the App") is developed and operated by Ingeniería.dev, led by Chris Flores (hereinafter, "we", "the Developer").

• Contact: [email protected]
• Address: Av. Javier Barros Sierra 495, Santa Fe Lomas de Santa Fe Zedec Santa Fé, Álvaro Obregón 01219, Mexico City, CDMX, Mexico

2. What data we collect

None. "Collect" here means what it means on the App Store privacy label: data that leaves your device and reaches us or a third party. Nothing does. Stepper Pro was built with privacy by default. The App:

• Does not require registration or an account
• Does not ask for your email, name, phone number, or any personally identifiable information
• Does not access your contacts, camera, microphone, photos, calendar, or health data
• Uses your location only if you allow it, only while a walk is in progress, and only on your device — it is never sent to us or to anyone else (see Section 3.2)
• Does not read from or write to HealthKit
• Does not include any third-party SDKs for analytics, advertising, tracking, or crash reporting
• Does not send telemetry or usage metrics to any server — we do not operate one
• Does not make any network requests of its own (see Section 5 for how Apple's map is displayed)

3. Motion and location access

Stepper Pro uses two sensitive permissions: Motion & Fitness, which it needs in order to count steps, and Location, which is optional. Both are processed on your device and neither is transmitted anywhere.

3.1 Motion & Fitness

The App requests access to Motion & Fitness to count the steps you take while walking.

• Motion readings are captured and processed exclusively on your device using Apple's CoreMotion framework.
• The App reads the device's accelerometer and gyroscope fusion (deviceMotion) while a walk is running, to detect the rhythm of your stride.
• Raw sensor samples are never stored. They are processed in memory as they arrive and discarded immediately; only the resulting totals for a walk you choose to save are written to disk.
• Motion data is never transmitted, uploaded, or streamed to any server — ours or a third party's.
• Sensor reading stops when you pause or finish a walk, and when the App leaves the foreground.
• You can revoke this permission at any time in Settings → Privacy & Security → Motion & Fitness. The App will tell you that counting is unavailable instead of failing silently.

3.2 Location (optional)

The App asks for Location — While Using the App. It never asks for "Always" access and never reads your location in the background.

• It is optional. If you decline, Stepper Pro works exactly the same as a treadmill step counter. Only outdoor distance and the route map are unavailable.
• Location is read only while a walk is in progress and the App is in the foreground. It is not read when no walk is running, and it is not read when the App is in the background.
• It is used for two things. First, to tell automatically whether you are on a treadmill or outdoors: if you are taking steps but your position is not changing, you are on a treadmill; if your steps are moving you, you are outdoors. Second, when you are outdoors, to measure the distance you cover and to draw your route on a map inside the App.
• The route and the distance of a walk are saved only on your device, together with the rest of that walk, and only if you choose to save the walk. If you discard the walk, its route is discarded with it.
• Location data is never transmitted, uploaded, or shared — not with us and not with any third party. The App has no server to send it to.
• You can delete any saved walk, together with its route, from the History screen at any time.
• You can revoke this permission at any time in Settings → Privacy & Security → Location Services → Stepper Pro. The App keeps working as a step counter.

4. What is stored on your device

The App stores locally (using SwiftData) only what's needed to show your history and settings:

Data	Purpose	Location
Saved walks (start time, end time, step count, active duration, average cadence)	Display your walk history	Device (SwiftData)
Outdoor walks only, and only if you allowed Location: distance covered and the route (the sequence of positions recorded during that walk)	Show the distance and draw the route on a map in your walk history	Device (SwiftData)
App preferences (language, onboarding state)	Remember your settings between sessions	Device (UserDefaults)

That is the complete list. No identifier of you, your device, or your Apple Account is stored. This data is never sent to the Developer's servers. If you delete a walk from the history, it is removed permanently together with its route; if you delete the App, all of this information is removed with it.

5. External services

Stepper Pro does not use any external services of its own. The App's code makes no network requests. It has no backend, no cloud sync, no analytics provider, no advertising network, and no crash reporter. Step counting works fully offline, including in airplane mode.

5.1 Apple Maps (MapKit)

When you open a saved outdoor walk, the App draws its route on a map using Apple MapKit, a framework that is part of iOS. The map imagery is loaded by Apple's system from Apple's servers; to do that, the system necessarily asks for the area of the map being displayed. Those requests are made by iOS, not by the App's own code, and they are governed by Apple's Privacy Policy. The App never uploads your recorded route, your distance, or your walk history to Apple, to us, or to anyone else. Without an internet connection the route is still recorded and saved; only the map background may not load.

6. System permissions

Stepper Pro requests only the permissions it actually uses:

• Motion & Fitness — required. Used only to count your steps locally. Motion data never leaves the device.
• Location — While Using the App — optional. Used only while a walk is in progress and the App is in the foreground, to tell a treadmill from an outdoor walk and, outdoors, to measure distance and draw your route. Location data never leaves the device. The App works without it.

The App does not request access to: "Always" or background location, camera, microphone, contacts, calendar, reminders, photos, media library, Bluetooth, local network, notifications, health data, or HealthKit.

7. Marketing and advertising

The App displays no ads. We do not collect data for remarketing, profiling, segmentation, behavioral analysis, or any promotional purpose. We do not participate in ad networks, and we do not sell information to third parties. The App never requests App Tracking Transparency permission because it performs no tracking of any kind.

8. Minors

The App is rated 4+. Because the App requires no registration and collects no data, it complies with COPPA (US), LGPD Infantil (Brazil), and GDPR-K (EU) by design.

9. User rights (GDPR, CCPA, LFPDPPP, LGPD)

Even though we collect no data, the following rights are guaranteed by design:

• Right to access: All your saved walks live on your device and are visible in the App's history screen.
• Right to rectification: You can delete any walk and change any preference at any time.
• Right to erasure: Deleting a walk from the history removes it, and its route, permanently. Uninstalling the App deletes everything.
• Right to portability: Not applicable — no data exists on external servers.
• Right not to be subject to automated decisions: The App detects steps using on-device signal processing, but no decision affecting legal rights, employment, credit, or insurance is made based on this data.

For any questions about your rights, please email [email protected].

10. Fitness context

Stepper Pro is a consumer fitness app, not a medical device. Step counts, cadence, distance, and duration are estimates produced by on-device processing and are intended for your personal reference only. They are not clinical measurements and are not intended to diagnose, treat, cure, or prevent any disease. No data produced by Stepper Pro is transmitted to HealthKit, to any health provider, or to any third party.

11. Security

Local data is stored inside the iOS sandbox, protected by the operating system and by device-level disk encryption (Apple's Data Protection API). The App's database is inaccessible to other apps on the device.

12. International transfers

We do not perform international transfers of personal data because we do not store personal data on any server. Your walks and routes never leave your device.

13. Changes to this policy

We may update this Privacy Policy to reflect changes to the App or to applicable law. The current version will always be published at this URL, along with the date of the last update. Material changes will also be announced inside the App.

14. Governing law

This Policy is governed by the laws of the United Mexican States, in particular the Federal Law on Protection of Personal Data Held by Private Parties (LFPDPPP). Any dispute will be submitted to the competent courts of Mexico City.
