Privacy Policy

Effective Date: March 16, 2026
Last Updated: March 16, 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:

the Block Guard Android app ("App"), and
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 locally on your device:

phone numbers associated with incoming, outgoing, missed, blocked, or reported calls;
call metadata such as date, time, duration, type, and related call-log details;
SMS and MMS message content, sender and recipient information, and timestamps, for the purpose of displaying conversations, filtering spam, and detecting suspicious messages;
contact names and phone numbers from your device contacts, used solely for display purposes such as showing caller or sender names in the App;
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.

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

The App uses data locally on your device to:

provide call blocking, call screening, spam detection, and related phone-protection features;
send, receive, and display SMS and MMS messages as a default messaging app;
identify, label, block, silence, or warn about unwanted calls and suspicious messages;
detect potential phishing or scam content in messages using on-device pattern matching;
display contact names alongside calls and messages for identification;
allow you to review and manage your blocking settings, call history, and message conversations;
improve on-device spam-detection accuracy based on your local blocking actions and labels;
comply with applicable law and enforce our terms.

5. On-Device Processing

Block Guard is designed to process all user data locally on your device. Call screening, call blocking, SMS and MMS message handling, spam detection, phishing and suspicious-message warnings, contact-name display, blocking rules, and user settings are all processed and stored on your device. None of this data is transmitted to Block Guard servers.

The App periodically downloads read-only reference data from blockguard.app over HTTPS, including a list of known spam phone numbers and a list of known phishing domains. These downloads do not transmit any of your personal data, messages, call history, contacts, or device information to our servers.

When you make or receive calls, or send or receive SMS and MMS messages, those communications travel through your wireless carrier and reach their intended recipients as part of normal telecommunications delivery. Block Guard does not route, relay, or transmit your calls or messages through its own servers.

6. AI / Model Improvement

Block Guard may use your blocking actions, spam labels, and related in-app actions to improve on-device spam-detection accuracy. This processing happens entirely on your device.

Spam-detection learning operates on-device only. No training data, model data, call data, message content, or contact information is sent to Block Guard servers for model improvement.
Contact names are not used for spam-detection training.

If we introduce any feature that transmits training-related data off-device in the future, 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

App data

The App does not collect or share your personal data, call history, message content, contacts, or blocking activity with Block Guard servers or with third parties. All App data remains on your device.

Legal obligations

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. Because the App does not transmit your data to our servers, this provision applies primarily to information you provide to us directly (for example, through support emails or the Website).

We do not sell App user data for advertising or any other purpose.

10. Permissions

Block Guard requests Android permissions only as needed to provide its features. Depending on the device, Android version, and enabled features, this may include permissions related to:

Phone and call log access, for call screening and blocking;
SMS and MMS, for sending, receiving, and displaying messages;
Contacts, for displaying caller and sender names;
Notifications, for alerting you about calls and messages;
Internet access, used only for downloading read-only spam and phishing reference lists from blockguard.app and for carrier-managed MMS retrieval.

Some features require default-handler status (for example, default Phone app or default SMS app). If you deny or revoke certain permissions, or do not grant default-handler status, 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 and Age Suitability

Block Guard is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through the App. The App is intended for users ages 18 and older, consistent with its target audience on Google Play.

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. The data practices described in Part B, including analytics, cookies, and tag management, apply exclusively to the Website and do not apply to the Block Guard Android app.

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;
cookie or similar-technology data used for analytics, functionality, security, and measurement.

17. How We Use Website Data

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 set cookies or use similar technologies to support analytics, functionality, or performance measurement. This analytics activity applies only to the Website and is entirely separate from the Block Guard Android app, which does not include any analytics or tracking SDKs.

19. Cookies and Similar Technologies

The Website uses cookies and similar technologies for:

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

You can manage or disable 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.
