Account & Data Deletion

Hudson Watch is engineered with strict data minimization and user sovereignty. You have the unconditional right to immediately and permanently delete your account, saved watch zones, push tokens, and preferences.

Package: com.hudsonwatch.app • Developer: Hudson Watch Team

Data Associated with Your Account

We collect only the bare technical minimum required to authenticate you and dispatch push notifications when vessels cross your user-defined geofences:

Account Email & Authentication Stored

The Google account email address you use to sign in. Stored to authenticate API calls and securely bind your custom watch zones and preferences to your profile.

Custom Watch Zones Stored

Fixed geographic circle coordinates (latitude, longitude, radius in meters) and zone labels you explicitly configure. Used strictly by our server-side engine to match against live AIS vessel positions.

Alert & Filter Preferences Stored

Your configured alert filters (e.g., minimum vessel speed, selective vessel types such as cargo, tanker, tug, passenger, or pleasure craft) and anti-chatter cooldown timers.

FCM Device Push Token Stored

Firebase Cloud Messaging token generated by Google Play Services on your Android device. Required solely to deliver native vessel entry and exit push alerts.

Data We Never Collect or Store

Our core architecture is intentionally designed without tracking infrastructure:

Zero Background Personal Location Tracking

Hudson Watch never requests, monitors, or logs your physical movements or background location. Geofences are fixed geographic coordinates evaluated entirely on our backend against public AIS maritime transponders—your personal location is never required to monitor vessels.

Zero Advertising Identifiers (Google Play AD_ID Removed)

Hudson Watch contains zero advertisements, zero marketing tracking SDKs, and has completely purged the com.google.android.gms.permission.AD_ID permission. We do not track you across apps or build commercial profiles.

Zero Third-Party Broker Tracking or Data Monetization

We do not sell, rent, monetize, or redistribute any user data, search queries, or watch zones to advertisers, data brokers, or third parties.

Zero Historical Movement Storage

Vessel AIS positions are held in transient RAM memory only to compute geofence transitions. We do not maintain historical movement tracks of ships, yachts, or your interactions.

How to Delete Your Account and Data

You can execute a complete and permanent erasure of your account through either of two direct mechanisms:

In-App Deletion Immediate In-App Deletion (Recommended)

If you currently have the Hudson Watch Android app installed, you can trigger immediate and irreversible account erasure with zero waiting period:

1

Open Settings

Launch Hudson Watch on your Android device and tap the Settings gear icon in the bottom navigation bar.

2

Select Delete Account

Scroll to the Account & Data Security section and tap Delete Account.

3

Confirm Irreversible Purge

Review the confirmation dialog. Tapping Confirm Permanent Deletion immediately purges all watch zones, preferences, push tokens, and revokes your authentication credentials. Your session is terminated immediately.

Web & Email Request Direct Deletion Request via Email

Per Google Play and GDPR standards, if you have uninstalled the app or cannot access your Android device, you can request complete erasure directly via email. For security and privacy reasons, requests must be sent directly from the email address registered with your account (we can only delete the account matching the sender's address). Timeline: In-app deletions take effect immediately. Web and email requests are permanently executed within 30 days of verification.

Retention & Purge Timelines

We do not retain dormant personal data. Timeline: In-app deletions take effect immediately. Web and email requests are permanently executed within 30 days of verification.

Data Category Normal Retention In-App Deletion SLA Web / Email SLA Purge Result

Irreversible Erasure Guarantee
