Intersafe exists to protect your browsing. That's all we do. We have no interest in your personal data, browsing habits, or online activity beyond keeping you safe. We believe a security tool that doesn't respect your privacy isn't worth using.
Intersafe is a browser extension focused entirely on web browsing protection. It guards against a wide range of online threats:
If you create an account, we store your email address and account plan. Your email is the minimum we need for login and password recovery. We do not use it for marketing or share it with anyone. Passwords are never stored in plain text. They are hashed using industry-standard encryption (bcrypt), meaning no one, including us, can see your password.
If you sign in with Google, we receive your email address from Google but do not access any other Google account data.
If you're on a Family plan, the plan owner can see the email addresses of the members they invite and how many browsers each member has connected, as needed to manage the shared plan. Members cannot see other members' details, and no browsing data, saved domains, or activity is ever shared between family members.
All threat detection happens locally in your browser. Intersafe does not send your browsing history, clipboard contents, or page content to our servers.
The extension stores the following data locally on your device:
If you create an account, your allowed domains list is synced to our server so it carries across browsers. Every domain is encrypted with AES-256-GCM using a key unique to your account before it leaves your browser. We store only the encrypted data. We cannot read, identify, or associate the saved domains with any recognizable content.
When the extension blocks a threat, it sends a single anonymous increment to a counter on our server. This request contains no user identity, no device or browser information, no URL, and no timestamp. It exists solely so we can verify that the core protection is working. We cannot trace any count back to a specific user or session.
Intersafe requests a set of browser permissions through the standard Chromium extension system. These permissions are required for Intersafe to protect you and are used solely for that purpose:
These are standard capabilities provided by Chromium-based browsers (Chrome, Edge, Opera, Brave, and others) to all extensions. Intersafe uses them strictly as a protective tool. All processing happens locally in your browser. Nothing is sent to our servers, and we have no access to your browsing data.
Intersafe uses Google's Safe Browsing Update API to check sites for malware and phishing. The URLs you visit never leave your browser. Instead, Intersafe downloads a local database of threat signatures from Google and checks URLs against it entirely on your device. Only if a partial match is found does Intersafe send a short, anonymous hash prefix to Google to confirm the threat. This prefix cannot be used to reconstruct the URL you visited. Google's use of this data is governed by Google's Privacy Policy.
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. This applies to both the Safe Browsing API above and Google OAuth sign-in described earlier in this policy.
Intersafe periodically downloads updated threat detection patterns from our server. This request does not include any personal data or browsing information.
We will update this list when we add or change service providers. Account holders will be notified of material changes at least 30 days in advance.
Local extension data stays on your device and is cleared when you uninstall the extension. Account data is retained until you delete your account. You can delete your account at any time from your Account Settings. When you delete your account, all associated data (profile, synced allowlist, browser registrations, and family membership) is permanently removed.
Intersafe is not directed at children under 16. We do not knowingly collect data from children.
Under GDPR and similar regulations, we process data on the following bases:
Depending on your location, you may have the following rights regarding your personal data:
To exercise any of these rights, email us at support@intersafe.app. We will respond within 30 days.
Given our small scale and the fact that all browsing data is processed locally on your device, we are not required to appoint a Data Protection Officer. For any privacy-related inquiries, contact us at support@intersafe.app.
We may update this policy from time to time. For material changes, we will notify account holders by email at least 30 days before the changes take effect. If you do not agree, you may delete your account before the effective date. Changes will also be posted on this page with an updated date.
