Privacy
Policy

Introduction

Welcome to Octilum. This Privacy Policy explains how Octilum ("we," "our," or "the App") handles information in connection with your use of our iOS application.

Octilum is designed with a privacy-first architecture. Your personal health and wellness data is stored locally on your device by default and is only synced to your personal iCloud account if you explicitly choose to enable iCloud Sync.

Data We Do Not Collect

Octilum does not collect, store, or transmit any of the following:

Data Stored Locally on Your Device

All health and wellness data you enter into Octilum is stored exclusively on your device using Apple's Core Data framework. This includes:

• Running logs and GPS route data (stored locally via MapKit — never transmitted)
• Sleep session records and sleep quality ratings
• Breathing and meditation session records
• Hydration (water intake) logs
• Nutrition logs and calorie tracking
• Workout logs including exercises, sets, reps, and weight
• Bodyweight records

This data is protected by iOS device encryption and your device passcode or Face ID authentication.

Apple HealthKit Integration

Octilum integrates with Apple HealthKit to optionally import health data recorded by your Apple Watch or iPhone.

Data Read from HealthKit

• Running distance (walking/running distance recorded by Apple Watch)
• Sleep duration and sleep analysis data

How HealthKit Data Is Used

• HealthKit data is accessed only upon your explicit confirmation
• Used solely to pre-populate your activity logs within Octilum
• Never shared with third parties or used for advertising
• Never stored on external servers

iCloud Sync (Optional)

Octilum offers an optional iCloud Sync feature that allows your data to be synchronized across your Apple devices using Apple's CloudKit infrastructure.

• iCloud Sync is disabled by default
• You must explicitly enable it in Settings → Data & Security
• When enabled, your data is encrypted and stored in your personal iCloud account
• Governed by Apple's iCloud Privacy Policy — not accessible to us
• Can be disabled at any time from within the app

We do not have access to your iCloud data. Data stored in iCloud is managed by Apple under your Apple ID, governed exclusively by Apple's iCloud Privacy Policy.

Firebase Services

Octilum uses Google Firebase exclusively for app content delivery — not for user data collection.

Device Authentication

Octilum uses Apple's Face ID and device passcode authentication (LocalAuthentication framework) to protect access to the app. This authentication is processed entirely on your device by iOS.

Octilum never receives, stores, or transmits your biometric data.

Subscriptions and Payments

Octilum offers premium access through auto-renewing subscriptions processed entirely by Apple's App Store. We do not collect or store any payment or financial information.

• Monthly and annual subscriptions processed exclusively by Apple
• 14-day free trial managed in accordance with App Store policies

For billing inquiries, refunds, or subscription management, visit your Apple ID account settings or contact Apple Support directly.

Children's Privacy

Octilum is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the app, please contact us at privacy@octilum.com.

Data Retention and Deletion

Since all personal health data is stored locally on your device, you have full control at all times.

• Delete individual entries from within the app at any time
• Deleting the Octilum app removes all locally stored data
• If iCloud Sync is enabled, existing iCloud data can be deleted via iOS Settings → Apple ID → iCloud → Manage Account Storage

Your Privacy Rights

Because Octilum does not collect personal data on external servers, there is no personal profile associated with you that we hold. You retain full ownership and control of your data at all times.

For any privacy-related questions or concerns, contact us at privacy@octilum.com.

Data Security

We implement appropriate technical measures to protect your data, including reliance on Apple's secure frameworks and device-level encryption. All health data stored locally on your device is protected by iOS encryption, accessible only through your device passcode or Face ID.

We do not create user profiles or track user behavior across apps or services. Octilum has no visibility into how you use the app beyond what you explicitly log.

Third-Party Services

Octilum integrates with the following third-party services. Their respective privacy policies govern how these services handle data:

• Apple HealthKit — apple.com/legal/privacy
• Apple iCloud / CloudKit — apple.com/legal/privacy
• Apple App Store (payments) — apple.com/legal/privacy
• Google Firebase Storage & Firestore — firebase.google.com/support/privacy

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date at the top of this document. Your continued use of Octilum after any changes constitutes your acceptance of the updated policy.
