Block GuardAndroid protection suite

Terms of Use

Last Updated: March 16, 2026

These Terms of Use (“Terms”) govern your use of the Block Guard Android application (“App”) and the Block Guard website at blockguard.app (“Website”), both owned and operated by RadStorm Technologies LLC (“RadStorm Technologies,” “Company,” “we,” “us,” or “our”).

By downloading, installing, or using the App, or by accessing the Website, you agree to be bound by these Terms. If you do not agree, do not use the App or Website.

We may update these Terms from time to time. When we do, we will revise the “Last Updated” date above and may provide additional notice where appropriate. Your continued use of the App or Website after changes take effect constitutes acceptance of the revised Terms.

1. License to Use

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable, limited license to:

  • download and use the Block Guard Android app on devices you own or control; and
  • access and use the Block Guard website for personal, non-commercial purposes.

This license does not transfer any ownership of intellectual property to you.

2. Intellectual Property

All content, design, code, trademarks, logos, and other intellectual property associated with the App and Website are the property of RadStorm Technologies LLC or its licensors. You may not reproduce, modify, distribute, sell, or create derivative works based on our intellectual property without our prior written consent.

3. Acceptable Use

You agree to use the App and Website only for lawful purposes and in accordance with these Terms. You may not:

  • use the App or Website for any unlawful purpose, including but not limited to harassment, fraud, or abuse;
  • use the App to send unsolicited bulk messages (spam), conduct robocalling, or engage in any abusive telecommunications activity;
  • attempt to reverse engineer, decompile, or disassemble the App beyond what applicable law expressly permits;
  • scrape, crawl, or use automated tools to extract content from the Website;
  • interfere with or disrupt the operation of the App, Website, or any related infrastructure;
  • impersonate another person or entity when using the App or Website;
  • circumvent or misuse any blocking, filtering, or spam-protection features in the App.

You remain solely responsible for all communications you send using the App, including compliance with applicable telecommunications laws and regulations.

4. Feature Availability and Limitations

The availability and behavior of App features may depend on factors outside our control, including:

  • your Android version and device manufacturer (OEM) behavior;
  • your wireless carrier’s support for call screening, SMS, and MMS;
  • Android permissions you grant or deny;
  • whether you set Block Guard as your default Phone app, default SMS app, or both;
  • network availability for features that download reference data.

Spam and scam detection, phishing warnings, caller identification, and call or message blocking are helpful tools designed to assist you, but they are not guarantees. No blocking or filtering system is perfect, and some unwanted communications may not be caught while some legitimate communications may be incorrectly flagged.

5. On-Device Processing and Privacy

The App processes your data locally on your device. Call screening, message handling, spam detection, phishing warnings, contact display, and blocking rules all operate on-device. The App does not transmit your calls, messages, contacts, call history, or blocking activity to Block Guard servers. For full details, see our Privacy Policy.

The App periodically downloads read-only reference data (such as known spam numbers and phishing domains) from blockguard.app over HTTPS. These downloads do not include any of your personal data.

6. User Content and Feedback

If you contact us through the Website, email, or other channels, any feedback, suggestions, or ideas you provide may be used by us without obligation to you. We do not collect personally identifiable information through the App itself; however, if you contact us directly, you may provide information such as your name and email address, which is subject to our Privacy Policy.

7. Purchases and Subscriptions

If the App offers paid features or subscriptions, purchases are processed through Google Play. Billing, refunds, and cancellation for Google Play purchases are governed by Google Play’s terms and policies. You can manage or cancel subscriptions through your Google Play account settings.

8. Third-Party Content and Links

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

9. Disclaimers

THE APP AND WEBSITE ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

WE DO NOT WARRANT THAT THE APP OR WEBSITE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS. WE DO NOT GUARANTEE THAT SPAM BLOCKING, SCAM DETECTION, PHISHING WARNINGS, OR ANY OTHER PROTECTIVE FEATURE WILL IDENTIFY ALL UNWANTED OR DANGEROUS COMMUNICATIONS.

YOU ASSUME TOTAL RESPONSIBILITY FOR YOUR USE OF THE APP AND WEBSITE.

10. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, RADSTORM TECHNOLOGIES LLC, ITS OFFICERS, DIRECTORS, AFFILIATES, AND LICENSORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, REVENUE, OR PROFITS, ARISING FROM OR RELATED TO YOUR USE OF THE APP OR WEBSITE, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), OR ANY OTHER LEGAL THEORY.

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the maximum extent permitted by law.

11. Indemnification

You agree to defend, indemnify, and hold harmless RadStorm Technologies LLC and its officers, directors, employees, and agents from and against any claims, losses, damages, liabilities, and expenses (including reasonable attorneys’ fees) arising from: (i) your use of the App or Website, (ii) your violation of these Terms, or (iii) your violation of any applicable law or third-party rights.

12. User Responsibilities

You are responsible for configuring and using the App appropriately. Some features require designation as the default Phone app or default SMS app, which may affect how other apps on your device handle calls or messages. You bear responsibility for understanding the impact of these settings.

You are responsible for maintaining your backup encryption password. We do not store your password and cannot recover encrypted backup data if your password is lost. Backup files are stored on your device or a storage location you choose; we do not store backup data on our servers.

13. Children and Age Suitability

The App and Website are not directed to children under 13. We do not knowingly collect personal information from children under 13. The App is intended for users ages 18 and older, consistent with its target audience on Google Play. If you are under 13, do not use the App or Website.

14. Termination and Suspension

We reserve the right to suspend or terminate your access to the App or Website if we reasonably determine that you have:

  • violated these Terms;
  • engaged in misuse, abuse, fraud, or harassment;
  • used the App in a manner that may expose us or others to legal liability; or
  • engaged in conduct that we determine, in our sole discretion, is harmful to other users, us, or third parties.

Provisions of these Terms that by their nature should survive termination (including disclaimers, limitation of liability, and indemnification) will survive.

16. Governing Law and Venue

These Terms are governed by the laws of the State of Wyoming, without regard to its conflict-of-laws provisions. Any dispute arising from these Terms or your use of the App or Website shall be subject to the exclusive jurisdiction of the state and federal courts located in Wyoming. If you access the App or Website from outside the United States, you are responsible for compliance with the laws of your jurisdiction.

18. Miscellaneous

Our failure to enforce any provision of these Terms does not constitute a waiver of that provision. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect. We may assign our rights and obligations under these Terms without your consent. You may not assign your rights or obligations without our prior written consent. These Terms, together with our Privacy Policy, constitute the entire agreement between you and RadStorm Technologies LLC regarding the App and Website.
