Security Extension

Privacy Policy

Last updated September 21, 2026

This Privacy Policy explains how Security Extension ("we", "us" or "our") collects, uses, and protects information when you use the Security Extension browser extension and the website securityextension.com (together, the "Service"). By installing the extension or using the site, you agree to the practices described here.

1. Who we are

The Service is a cybersecurity browser extension that helps protect you while you browse, for example by blocking pop-ups, warning you about scam and phishing sites, and reducing intrusive ads and trackers. We operate the Service and are responsible for the information handled as described in this policy. For any privacy question, contact us at privacy@securityextension.com.

2. Information we collect

Information you provide

If you create an account, contact support, or subscribe to updates, you may give us information such as your name, email address, and any message you send us.

Information collected automatically

When you use the Service, we may collect limited technical information such as extension version, browser type and version, operating system, language, a randomly generated device or installation identifier, and basic usage events (for example, that a threat was blocked). This helps us keep the extension working and improve it.

Information the extension processes to protect you

To detect scams, phishing pages, malicious sites, and unwanted content, the extension needs to evaluate the web addresses (URLs) and certain page signals of the sites you visit. Wherever possible this checking is performed on your device, or through privacy-preserving lookups (for example, using shortened or hashed identifiers) so that we do not need to receive your full browsing history. We do not build advertising profiles from your browsing, and we do not sell your browsing data.

3. Browser permissions

Browser extensions must request permissions to function. We request only the permissions needed for the features you use, and we use them only for the purposes described below.

PermissionWhy we use it
Read and change data on the sites you visitTo detect and block scam, phishing, and malicious pages, pop-ups, ads, and trackers as pages load.
StorageTo save your settings and preferences on your device.
Tabs / active tabTo apply protection to the page you are currently viewing.
NotificationsTo warn you when a threat is blocked (if you enable alerts).

We never use these permissions to collect content you type (such as passwords or messages) for advertising, and we do not sell data obtained through them. Remove the extension at any time to revoke all permissions.

4. How we use information

  • To provide, maintain, and secure the Service and its protection features.
  • To detect, prevent, and respond to scams, fraud, malware, and abuse.
  • To fix bugs, measure performance, and improve our features.
  • To respond to your requests and provide support.
  • To send you service messages, and, with your consent, product updates.
  • To comply with legal obligations and enforce our terms.

5. How we share information

We do not sell your personal information. We share information only in these limited cases:

  • Service providers. Vendors who host our infrastructure, provide analytics, or deliver support on our behalf, under contracts that limit their use of the data.
  • Threat intelligence. We may share anonymized or aggregated indicators of malicious sites to help detect threats, in a form that does not identify you.
  • Legal reasons. When required by law, regulation, or valid legal process, or to protect the rights, safety, and security of our users and the public.
  • Business transfers. In connection with a merger, acquisition, or sale of assets, subject to this policy.

6. Data retention

We keep information only for as long as needed for the purposes described here, or as required by law. Settings live on your device until you remove the extension. Diagnostic and usage data are kept for a limited period and then deleted or anonymized. You can ask us to delete your account data as described below.

7. Data security

We use technical and organizational measures such as encryption in transit, access controls, and data minimization to protect information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security, but we work to protect your information and to respond quickly if an issue arises.

8. Your rights and choices

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal information, to object to or restrict certain processing, and to withdraw consent. If you are in the EEA or UK, these rights arise under the GDPR. If you are in California, you have rights under the CCPA and CPRA, including the right not to be discriminated against for exercising them, and we confirm that we do not sell or share personal information as those terms are defined there.

To exercise any right, email privacy@securityextension.com. You can also uninstall the extension at any time, which stops all further data processing by it.

9. International transfers

We may process and store information in countries other than where you live. Where we transfer personal information across borders, we use appropriate safeguards, such as standard contractual clauses, as required by applicable law.

10. Cookies and similar technologies

Our website securityextension.com may use cookies and similar technologies to remember your preferences and understand site usage. You can control cookies through your browser settings. The extension itself uses local storage on your device to save settings, not advertising cookies.

11. Children's privacy

The Service is not directed to children under the age of 13 (or the minimum age required in your country), and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.

12. Third-party sites

The Service may show warnings about, or link to, third-party websites. We are not responsible for the privacy practices of those sites. We encourage you to read their privacy policies.

13. Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the date above and, where appropriate, provide a more prominent notice. Your continued use of the Service after changes take effect means you accept the updated policy.
