TATSU: Passive Digital Detox

Tired of saying "I'll quit tomorrow"?

"I just keep scrolling..."
"I set a timer, but I ignore it anyway..."
Isn't it time to stop relying on willpower for your digital detox?

TATSU is a new kind of "passive" digital detox app designed around the concept of "no willpower needed." You don't have to psych yourself up to put your phone away. Just let the system take over, and seamlessly reduce your screen time without the stress.

💡 Why TATSU Works

1. It's "Passive", So You'll Stick With It
Unlike "active" lock apps where you have to manually set timers, TATSU smartly and automatically interrupts your app usage based on your rules. The moment you mindlessly try to open a distracting app, TATSU acts as a buffer, stopping social media scrolling and video binges at the source. You don't have to do a thing.

2. Collect Adorable "Pixel Cats"
Your reward for a successful detox? Cute pixel art cats! Earn various Pixel Cats based on the time you spend away from your phone or by meeting specific conditions. Your cats are safely stored in your "Electronic Cat File." The joy of collecting will keep you motivated for the long haul. (*More cat breeds coming in future updates!)

3. Privacy By Design
All your data—settings, usage history, and your cat collection—is processed and stored entirely on-device as local data. Unlike some other apps, TATSU never transmits your data to external servers. Enjoy your digital detox with complete peace of mind.

4. Beautiful, Intuitive Analytics
Which apps did you limit, and by how much? How did you do this week? Your hard work is visualized on a modern, stylish UI. Seeing your daily progress turns "not using your phone" into a highly positive and rewarding experience.

✨ Perfect For You If:

・You can't stop doomscrolling before bed.
・You want to focus on work or study but keep reaching for your phone.
・You've downloaded screen time apps before, only to delete them days later.
・You love retro pixel art and collecting cute cats.

【⚠️ About Permissions & Privacy (Important)】
This app uses the AccessibilityService API and "Display over other apps" permission solely for the purpose of detecting the launch of user-specified restricted apps and displaying a forced block screen.
We do not use these powerful permissions to read your screen content, log your inputs, or collect/transmit any personal information externally. Please use the app with confidence.

Let today be the last day you rely on sheer willpower to control your screen time.
With TATSU, reclaim a richer, more meaningful life that's truly yours.
