Privacy by Design in LiFi

Privacy in LiFi isn’t a secondary feature. It is a foundational design principle that shapes every part of the extension — from how data is collected, to where it’s stored, to how you interact with it.

This page explains how LiFi protects your privacy through thoughtful architecture, local-first data handling, and full transparency.

Local-Only Data Storage

LiFi stores 100% of user data locally using Chrome's built-in Storage API. This means:

  • No third-party servers receive your data

  • No external sync unless you explicitly export it yourself

  • No cloud dependence for analytics or tracking

All browsing activity, interaction records, and AI-generated summaries are stored within the browser’s secure local storage. You can view, export, or delete this data at any time from the dashboard.

Why this matters:

Benefit
Explanation

Data stays on device

No risk of data leaks or breaches from cloud infrastructure

No account required

Users don’t need to log in or create profiles

Works offline

Analytics features continue functioning even without internet


LiFi integrates with AI models (e.g., Google Gemini) to provide intelligent summaries. However:

  • No data is ever sent without your explicit permission

  • You must manually trigger AI-powered insights

  • Prompts are generated locally, and only relevant summary data is transmitted

This opt-in model ensures that you remain fully in control over when — and if — your data leaves your browser.


No Sensitive Personal Data Collection

LiFi does not collect any of the following:

  • Passwords

  • Payment information

  • Personally Identifiable Information (PII) such as names, emails, phone numbers

By design, the extension avoids input fields where sensitive data is typically entered. Additionally, smart filters are used to ignore common sensitive form fields.


Sandboxing and Security Architecture

LiFi uses content script sandboxing to ensure that data collection is safe and isolated. Each content script runs in a separate execution environment that:

  • Cannot modify webpage behavior

  • Cannot read or interfere with other scripts on the page

  • Only extracts high-level behavioral data (like page titles, interaction events)

Combined with Chrome’s Content Security Policy (CSP), this architecture prevents malicious access and enforces strict boundaries between LiFi and the websites you visit.


LiFi actively monitors cookies from all visited sites to help you stay aware of invisible tracking mechanisms.

Feature
Function

Cookie change tracking

Detects when new cookies are added or old ones are removed

Third-party cookie detection

Highlights cookies that originate from non-visited domains

Cookie metadata analysis

Flags insecure or privacy-invasive cookie configurations

Privacy scoring engine

Assigns a privacy score to each session or domain

This gives users the tools to understand how websites handle their privacy — even if the site itself doesn’t explain it.


Compliance-Ready Privacy Controls

LiFi includes features that align with modern privacy regulations (like GDPR and CCPA), including:

Control Feature
User Right Supported

Full Data Export

Right to access

Complete Data Deletion

Right to be forgotten

Manual Tracking Toggle

Right to opt out of processing

Transparent Logs

Right to be informed

There is no hidden data collection and no hidden logs. Users can audit their own data at any time via the dashboard or exported JSON files.

Summary

LiFi demonstrates that powerful analytics can coexist with complete user privacy. Its privacy-first design ensures:

  • You never lose control over your data

  • You can see exactly what’s being tracked — and why

  • You can enjoy AI-powered insights without sacrificing security

Privacy isn’t a feature in LiFi. It’s the foundation of the entire system.
