About

In a world full of digital distractions, have you ever lost your focus amidst countless open tabs?
Breathing Browser Enhanced is the advanced evolution of the Standard version. We combine the science of "Rhythmic Entrainment" with the classic "Pomodoro Technique", perfectly merging time management with mind-body regulation.

[Core Principle]
This is not just a timer; it is a "visual biological clock."
Once activated, a gentle halo pulses at the edge of your screen. It acts as both your breathing coach and your work pacer.
During "Work Time," it guides you to maintain an alert, focused rhythm; during "Rest Time," it automatically switches to a relaxation rhythm, helping your brain recharge quickly.

[Key Benefits]
✨ Structured Focus: Built-in Pomodoro timer automatically manages the 25-min work / 5-min rest cycle.
🧠 Mental Endurance: Regulates brain oxygenation through breathing, reducing fatigue during long work sessions.
🌬️ Passive Guidance: operates in the background without taking up desktop space or making distracting sounds.
🌿 Auto-Regulation: Boosts energy during work and enforces relaxation during breaks, making "rest" truly effective.

--------------------------------------------------------------------------------------------------------------------------
👁️ Feature Breakdown:
This extension includes the following advanced features:

1. Pomodoro Breath Pacer

Description: Automatically cycles between "Work" and "Rest" modes, paired with corresponding breathing frequencies.
Work Mode: 25-minute countdown. The halo pulses at a balanced 5s inhale / 5s exhale rhythm.
Rest Mode: 5-minute countdown. The halo automatically switches to a relaxing 4s inhale / 8s exhale rhythm.
2. Visual Breathing Pacer

Description: Overlays a transparent Canvas layer on top of the current webpage to display a rhythmic glowing halo.
How it works: The halo brightens to cue "inhale" and dims to cue "exhale." It operates silently without interrupting your thoughts.
3. Smart Background Detection

Description: Ensures the halo is clearly visible and comfortable on any website.
How it works: The system instantly identifies the brightness of the webpage background and automatically switches between a light or dark halo.

⚠️ Technical & Permission Transparency:
To ensure transparency and your peace of mind, we explain exactly why specific permissions are needed:

Q: Why is the "Read and change all your data on the websites you visit" permission required?

This is a standard browser warning. In reality, we only perform the following two operations:

1. Drawing the Overlay:
We need to insert a transparent <div> or <canvas> element over the webpage you are viewing to display the breathing halo. To do this, the extension must have permission to inject code into the current page (Content Script).

We do NOT read any text, passwords, or form data on the page.
2. Detecting Background Color:
To implement "Smart Background Detection," we need to read the backgroundColor style property of the webpage's <body> tag. This is solely to determine if the page is dark or light, so we can display a white or black halo accordingly.

We only read the style (CSS), NOT the content.

--------------------------------------------------------------------------------------------------------------------------
🔒 Privacy Commitment:

All operations (Pomodoro timing, halo rendering, color detection) are performed locally within your browser.
No data is ever transmitted to external servers.
