Privacy Policy

Hence - Vehicle Management App

Last Updated: 3 October 2026

Effective Date: March 31, 2026

1. Introduction

Hence ("we", "our", "the App") is committed to protecting your privacy. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your personal information.

2. Data We Collect

2.1. Account Information

2.2. Vehicle Data

2.3. Transaction Records

2.4. Location Data

2.5. Device and Usage Data

2.6. Purchases and Subscription Status

3. How We Use your Data

We use the collected data solely to:

We do not use your data for advertising, profiling, or selling to third parties.

4. Data Storage

4.1. On-Device Storage

Your data is stored locally on your device using Apple's SwiftData framework. This data remains on your device and is protected by your device's built-in security (passcode, Face ID, Touch ID).

4.2. Cloud Storage

Firebase Firestore stores account-linked vehicle records for backup and sync. Firebase Storage stores uploaded maintenance and expense receipt images, document images, and parking photos. Saved locations and favorite stations are not currently included in Firebase backup. Image transfers can fail independently of record sync; keep original attachments.

The App does not use iCloud/CloudKit sync in this version. Builds before 1.3.5 offered an optional iCloud Sync setting; data previously synced that way remains in your own Apple iCloud account until you remove it in iOS Settings > [your name] > iCloud > Manage Account Storage.

Cloud communications use HTTPS/TLS. Firebase records are organized under your account identifier.

4.3. Credentials

Authentication credentials are managed by Firebase and the sign-in providers. AI and map requests use Hence's backend-managed service credentials; you do not supply an OpenAI API key. Credentials used by the app are kept in platform credential storage where applicable, not in exported vehicle records.

5. Third-Party Data Sharing

5.1. Data We Do NOT Share

5.2. Data Shared with Service Providers

We share limited data with the following service providers solely to operate the App:

Service Provider Data Shared Purpose
Firebase (Google) Account info, synced app data, images Authentication, cloud storage, sync, and image hosting
Google Sign-In OAuth token Account authentication
Apple Sign-In OAuth token Account authentication
Google Maps Platform (via our backend proxy) GPS coordinates, search queries, route origin/destination Nearby fuel station/EV charger search, route planning, road snapping for trip tracking
OpenAI (via Hence's backend) Compressed receipt, document, RC card, fuel dispenser, and odometer images AI-powered extraction from scanned images
mypetrolprice.com City name used for the lookup City-level fuel price estimates; the city may be resolved from location or selected by you
Apple App Store and Hence's backend Product and transaction identifiers, signed transaction data, expiration and subscription status linked to your account Purchase verification, entitlement restoration, and usage limits

5.3. AI-Powered Scanning

When you use AI-powered scanning, images are compressed and sent through Hence's backend to OpenAI for extraction. The app does not require a user-supplied OpenAI API key. AI scanning is optional and uses the AI processing consent setting.

If you decline AI scanning, documents remain available for local attachment and manual entry; document scanning does not provide on-device OCR. Receipt and RC-card scanners support on-device OCR where available. Guests can capture or attach document images locally, while AI document extraction requires an account.

Images may contain personal information such as registration numbers and owner details. They are sent for extraction, not advertising. Images you attach to records remain in your local data and may be backed up when sync is used. Backend and OpenAI operational retention depends on the service configuration and provider policies; we do not promise immediate deletion or zero retention by those services.

6. Data Retention

For incomplete deletion or questions about provider retention, contact the privacy address below. Export records and original attachments you want to keep before deletion.

7. your Rights

7.3. Deletion

7.4. Data Portability

You can export all your data before deleting your account using the App's export feature.

7.5. Consent Management

You can manage your data processing consents at any time via Profile > Privacy & Data. Available consent controls include:

Consent settings control optional features; device permissions are managed separately in iOS Settings. Previously collected data is not erased by changing a consent or disabling sync.

8. Children's Privacy

Hence is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children. If we become aware that we have collected data from a child under 18, we will take steps to delete it promptly.
