At Nixxer, privacy isn’t an afterthought—it’s our foundation. We built Nixxer specifically to protect your privacy by blocking web tracking, and we apply these same principles to how we handle your data. This policy explains our privacy practices for both the Nixxer browser extension and our supporting website.

The Bottom Line: We currently collect no personal data, transmit no information to our servers, and store everything locally on your device under your complete control.
What This Policy Covers

This privacy policy applies to:

The Nixxer browser extension
The Nixxer website hosted at www.nixxer.io via GitHub Pages
Any future services we may offer (with separate consent required)


Information We Collect
Current Data Collection: None

Browser Extension:

We do not collect, store, or transmit any personal information
We do not track your browsing activity
We do not send any data to external servers
All tracking detection and blocking happens entirely on your device


Website:

We do not use analytics packages
We do not set tracking cookies
We do not collect visitor information
We do not store any data about your visits


Local Data Storage (Browser Extension Only)

The Nixxer extension stores the following information locally in your browser’s storage:

Tracking Domain Database:

List of detected tracking domains encountered during your browsing
Frequency counters for blocked tracking attempts
Timestamp information for when domains were first detected


User Preferences:

Extension settings and configuration options
Blocklist format preferences
Display preferences for statistics


Important Notes About Local Storage:

All data remains on your device and never leaves your browser
You have complete control over this data
You can clear this data at any time through your browser settings
No other applications or services can access this data without your explicit permission


How We Use Information

Since we don’t collect external data, there’s no traditional “data use” to describe. However, here’s how the extension works:

Local Processing:

The extension analyzes web requests locally to identify tracking attempts
Statistics are calculated and stored locally for your reference
Blocklists are generated locally based on your browsing patterns


Export Functionality:

When you choose to export data, the extension packages your locally stored information
Exports are generated on your device and saved to your chosen location
We never see or receive copies of your exported data


Data Sharing and Disclosure

Current Practice: We share no data because we collect no data.

Third-Party Services:

GitHub Pages: Our website is hosted on GitHub Pages, which may collect basic server logs as part of their service
Browser APIs: The extension uses standard browser APIs but only for local processing


Legal Disclosure:

Since we don’t collect data, there’s nothing to disclose
We will update our privacy page if our privacy practices ever change


Your Data Rights and Control

Complete Control:

You own all data generated by the extension
You can export your data in multiple formats (Pi-hole, NextDNS, hosts file, AdGuard)
You can delete all extension data by removing the extension or clearing browser storage


No Account Required:

No registration or account creation needed
No password or personal information required
You remain anonymous while using our services


Third-Party Services

GitHub Pages:

Our website is hosted on GitHub Pages, a service provided by GitHub, Inc.
GitHub may collect basic server logs as part of their hosting service
We recommend reviewing GitHub’s privacy policy for their data practices
We chose GitHub Pages specifically because it’s a static hosting service with minimal data collection


Browser Storage:

The extension uses your browser’s local storage APIs
This data is subject to your browser’s privacy controls
Different browsers have different policies for local storage


Cookies and Tracking

Our Practices:

We do not use cookies on our website
We do not use any tracking technologies
We do not participate in cross-site tracking


Third-Party Cookies:

GitHub Pages may use minimal cookies for their hosting service
Your browser extension blocks tracking from other websites as designed

Future Services and Changes

Premium Services:

We may offer optional premium services in the future, such as curated blocklist distribution
Any premium service would require explicit opt-in and separate consent
We would never change our privacy practices for existing free services without clear notice


Data Collection Changes:

Any future data collection would be clearly disclosed in advance
We would require explicit user consent before implementing any data collection
Users would have the option to continue using existing services without new data collection


Policy Updates:

We will provide 30 days’ notice before any material changes to this policy
Notice will be provided through the extension interface and our website
Continued use after notice period constitutes acceptance of changes


Data Security

Local Security:

Data stored locally is subject to your device’s security measures
We recommend keeping your browser and operating system updated
Consider using browser profiles or private browsing for additional privacy


No Server Security Issues:

Since we don’t store data on servers, there’s no risk of server-side data breaches
Your data cannot be compromised through our systems because it never reaches our systems


International Users

Data Location:

All data processing happens locally on your device
No data crosses international borders through our services
GitHub Pages may have international server locations for website hosting


Legal Compliance:

We are committed to respecting privacy laws in all jurisdictions
Since we don’t collect data, most privacy regulations don’t apply to our current practices
We will comply with applicable laws if we ever change our data practices
