Effective Date: March 12, 2026
Last Updated: March 12, 2026

RadStorm Technologies LLC ("RadStorm Technologies," "Company," "we," "us," or "our") respects your privacy. This Privacy Policy explains how we handle information in connection with:

  1. the Block Guard Android app ("App"), and
  2. the Block Guard website and related web pages ("Website").

Because the App and the Website use data differently, this Privacy Policy is divided into separate sections. Part A applies to the Android app. Part B applies to the Website.

Part A - Block Guard Android App Privacy

1. Scope

This section applies only to the Block Guard Android app.

2. Information the App May Access or Use

Depending on your device, Android version, granted permissions, enabled features, and how you use the App, Block Guard may access or use the following categories of information:

  • phone numbers associated with incoming, outgoing, missed, blocked, or reported calls;
  • call metadata such as date, time, duration, type, and related call-log details;
  • user-created block lists, allow lists, preferences, schedules, and settings;
  • spam labels, block/report actions, and other in-app user actions;
  • notification-related data needed to display or manage call and message alerts;
  • limited diagnostic or technical information needed to maintain app functionality, stability, and security.

3. Contact Names

Block Guard is designed so that contact names are not required for AI training or spam-model improvement. If names are shown anywhere in the App through Android-provided call or contact interfaces, they are not used for model training unless this Privacy Policy is updated to state otherwise.

4. How the App Uses Data

We may use App-related data to:

  • provide spam blocking, call protection, and related phone features;
  • identify, label, block, silence, or warn about unwanted calls;
  • allow you to review and manage your call-protection settings and history;
  • improve spam-detection performance and related App functionality;
  • maintain app security, prevent abuse, troubleshoot issues, and support users;
  • comply with applicable law and enforce our terms.

5. On-Device Processing

Block Guard is designed to perform as much processing as possible locally on your device. Depending on the feature, call-related data may be processed in memory or stored locally on your device to provide App functionality, including spam detection, call management, settings, and user-controlled learning features.

If a feature operates entirely on-device, the relevant data may never be transmitted to our servers.

6. AI / Model Improvement

Block Guard may use limited call-related information, including phone-number-derived data, call metadata, user-applied spam labels, and related feature data, to improve spam-detection performance.

Current intended design

  • We intend for AI and model-improvement features to operate primarily or entirely on-device where possible.
  • We do not use contact names for AI training.
  • We aim to minimize duplication of sensitive data and avoid storing unnecessary data.

Important note

If we later introduce any feature that transmits training-related or model-improvement data off-device, we will update this Privacy Policy and any required in-app disclosures before doing so.

7. Data Storage and Retention

We retain data only for as long as reasonably necessary to:

  • provide App features you use;
  • maintain settings and protections you enable;
  • support local spam-detection or learning functionality;
  • maintain security and prevent abuse;
  • comply with legal obligations;
  • resolve disputes and enforce our agreements.

Retention may depend on whether the relevant data is:

  • stored only on your device;
  • deleted by you through the App or Android settings;
  • removed when you uninstall the App;
  • cleared through any in-app reset or delete feature we provide.

8. User Controls and Deletion

You may be able to control or delete certain App-related data through:

  • Android system settings and permission controls;
  • Block Guard settings and feature toggles;
  • in-app reset, clear, or delete options, where available;
  • uninstalling the App.

If the App provides a Delete Learned Data, Reset AI Data, Clear Local Training Data, or similar feature, using that feature is intended to remove the corresponding locally stored training-related data maintained by the App on your device.

If you contact us with a privacy request, we will review it in accordance with applicable law and the actual data we control.

9. Data Sharing

On-device processing

For features that operate entirely on-device, the underlying call-related data used only for local processing is not shared with third parties merely because it is processed on your device.

Service providers

We may use service providers to support the operation of our business and services, such as website hosting, customer support, email, analytics, diagnostics, or security services. These providers may receive limited information as necessary to perform services on our behalf.

Legal and business transfers

We may disclose information if required by law, to protect rights or safety, to investigate misuse, or in connection with a merger, acquisition, financing, asset sale, or similar transaction.

We do not sell phone-number-related App data for third-party advertising purposes.

10. Permissions

Block Guard may request Android permissions only as needed to provide its features. Depending on the device and enabled features, this may include permissions related to phone, call logs, notifications, contacts, SMS, or related telecom functionality.

If you deny or revoke certain permissions, some features may not function correctly.

11. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information handled by the App. However, no method of storage, transmission, or security is completely secure, and we cannot guarantee absolute security.

12. Children

Block Guard is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through the App.

13. International Use

If you use the App from outside the United States, you understand that your information may be processed in the United States or other jurisdictions where our providers operate, subject to applicable law.

14. Changes to This App Privacy Section

We may update this App Privacy section from time to time. When we do, we will revise the "Last Updated" date above and may provide additional notice when required.

Part B - Website Privacy

15. Scope

This section applies only to the Block Guard website and related web pages, including marketing pages, contact pages, support pages, and any related forms or content.

16. Information We May Collect Through the Website

Depending on how you use the Website, we may collect:

  • information you provide directly, such as your name, email address, company name, or message contents if you contact us;
  • technical and usage data, such as IP address, approximate location, browser type, device type, pages visited, referral source, and interactions with Website content;

18. Analytics and Tag Management

The Website currently uses Google Tag Manager and may use measurement, functionality, or similar tags configured through that service to understand traffic and visitor behavior.

These technologies may collect information such as:

  • pages viewed;
  • time spent on pages;
  • device and browser information;
  • approximate geographic region;
  • referral source;
  • interactions with Website content.

Tags deployed through Google Tag Manager may use cookies or similar technologies to support measurement, functionality, security, or performance.

19. Cookies and Similar Technologies

The Website may use cookies and similar technologies for:

  • basic functionality;
  • analytics and performance measurement;
  • remembering settings or preferences;
  • security and fraud prevention.

You may be able to manage cookies through your browser settings. Disabling cookies may affect some Website functionality.

20. Third-Party Services and Links

The Website may include links to third-party websites, services, or platforms. We are not responsible for the privacy practices of third parties. Your use of third-party services is governed by their own terms and privacy policies.

21. Website Data Retention

We retain Website-related information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

22. Website Privacy Choices

Depending on the tools we use and your location, you may be able to:

  • manage cookies through your browser settings;
  • contact us to request deletion of messages you submitted through the Website;
  • use available controls offered by analytics or advertising providers.
