02 Data We Collect

We only collect the data necessary to operate our services.

Web application (my.offbet.app)

  • Account data: email address, display name, country of residence.
  • Technical data: IP address, User Agent, usage logs.
  • App usage data: chosen settings, blocking preferences.
  • Subscription data: Stripe customer ID and subscription status. No credit card numbers are stored on our servers — Stripe handles all payment data.

Android application

  • Anonymous device identifier: a random UUID generated locally on first launch. This identifier has no link to your IMEI, Android ID, or any hardware identifier.
  • Device model and Android version: used to adapt the app behavior to your phone (Pixel, Samsung, Xiaomi, etc.).
  • Protection status: whether OFFBET protection is active or not, transmitted every 5 to 15 minutes to the OFFBET server for companion monitoring.
  • Blocked attempts: the list of gambling domains and applications blocked by the app, with attempt counts. This information is used to generate companion reports.
  • Installed applications list: only accessed when you open the “Block a custom app” screen. This list is never transmitted to the OFFBET server — it remains on your device.
  • PIN code hash: if you have set a PIN, its bcrypt hash (irreversible) is synchronized between your devices via the OFFBET server. The PIN itself is never transmitted.

What we do NOT collect

We do not collect browsing history, DNS queries, GPS location, contacts, photos, messages, or any sensitive personal data. No financial data is stored on our servers.


03 How We Use Your Data

Your data is used exclusively to:

  • Block access to gambling websites and apps via local DNS filtering on your device.
  • Ensure the PIN-protected uninstall prevention works correctly.
  • Monitor protection status and notify your companion in case of bypass attempts.
  • Synchronize your settings and blocklist between your devices.
  • Improve the stability and performance of OFFBET services.

We never sell your data to third parties.



05 Your Rights

You have the following rights over your personal data:

  • Access: obtain a copy of the data we hold about you.
  • Rectification: correct any inaccurate information.
  • Deletion: request complete deletion of your data.
  • Restriction: temporarily limit certain processing activities.
  • Objection: refuse certain uses, such as automatic renewal.
  • Portability: transfer your data to another provider.
  • Withdrawal of consent: revoke any specific authorization at any time.

06 Technical Operations & Security

DNS filtering (100% local)

On Android, OFFBET uses the Android VpnService API to create a local VPN connection on your device. This VPN does not route your traffic to any external server.

Instead, it intercepts DNS queries locally on your phone, blocks gambling-related domains by returning an empty response, and forwards all other queries to Google Public DNS (8.8.8.8).

No DNS query ever leaves your device to reach an OFFBET server. This is the same approach used by well-known apps such as AdGuard, Blokada, and Freedom.to.

Data transmission security

All communication between the OFFBET app and the OFFBET server (my.offbet.app) is encrypted using HTTPS/TLS 1.3.

The heartbeat signal sent every 5 to 15 minutes contains only your anonymous device ID, protection status, and blocked attempt counts — never your browsing history or DNS queries.

App blocking (UsageStatsManager)

OFFBET uses the UsageStatsManager API to detect when a blocked gambling application is launched and bring the user back to the home screen.

This data is processed locally on your device and is not transmitted to the OFFBET server.

AccessibilityService API (optional)

If enabled by the user, OFFBET uses the AccessibilityService API exclusively to:

  • Detect attempts to activate a third-party VPN that would bypass the gambling protection.
  • Detect changes to the device Private DNS settings.

This service is never used to read, interact with, or collect data from any other application. It is optional and can be skipped during setup.

Device Administrator (optional)

If enabled by the user, OFFBET registers as a Device Administrator to prevent accidental or impulsive uninstallation of the app.

The user can always disable this protection by entering their PIN code. This feature is voluntary and can be skipped during setup.

PIN code protection

When you enable PIN protection:

  • Disabling the protection or uninstalling the app requires entering the PIN code.
  • The PIN is hashed using bcrypt (irreversible) and verified locally — no network connection is needed.
  • If the “hidden PIN” option is chosen, only a trusted person knows the code. The user can request recovery via email after a configurable delay (12h, 24h, 48h, or never).
  • After 3 failed PIN attempts, the app locks and notifies the companion.

07 Android Permissions Explained

The OFFBET Android app requests the following permissions. Each permission is explained below with its purpose.

Permission Purpose
Internet Communicate with the OFFBET server (heartbeat, blocklist updates, account sync).
VpnService Create a local VPN connection to filter gambling DNS queries on your device. No traffic is sent to an OFFBET server.
Foreground Service Keep the DNS filtering and app blocking services running reliably in the background.
Boot Completed Automatically restart protection after your phone reboots.
Notifications Show a persistent notification confirming that protection is active.
Usage Stats Access Detect when a blocked gambling app is launched and redirect you to the home screen.
Query All Packages Allow you to select custom apps to block in OFFBET settings.
Ignore Battery Optimizations Prevent Android from killing the protection service to save battery.
Draw Over Other Apps optional Display the PIN entry screen on top of other apps when a bypass attempt is detected.
Device Administrator optional Prevent uninstallation of the app without entering the PIN code.
Accessibility Service optional Detect and prevent activation of third-party VPNs that would bypass the gambling protection.

All optional permissions can be skipped during setup. The app will remind you of missing permissions with a banner, but will never force you to enable them.

GDPR note: OFFBET never sees your DNS queries. Since filtering is 100% local, no browsing data is collected, stored, or transmitted. This eliminates the privacy risks associated with server-side DNS filtering.


08 Data Retention

Technical data (logs, IP, GUID) is retained for a maximum of 12 months, unless required by law or in case of a dispute.

Account-related data is deleted immediately upon your deletion request.

No data is retained beyond what is necessary for the service.


09 International Transfers

Our servers may be hosted by providers located outside the European Union (e.g., AWS).

In such cases, we ensure that appropriate safeguards (European Commission standard contractual clauses) are in place to protect your data.


10 Policy Changes

We may update this privacy policy to reflect changes in our services or applicable regulations.

Any updated version will be published on our website with a new effective date.
