CosmoQuit
CosmoQuit is a free quit smoking application designed to support smoking cessation through habit awareness, progress tracking, and behavioral support—without pressure, ads, or data exploitation.
Hi, I'm Sivabalan Thangadurai, founder of Cosmonika and the solo developer behind CosmoQuit. Based in Kanyakumari, Tamil Nadu, India, I built this app because I believe people trying to quit smoking deserve better than what's currently available.
I was frustrated by quit-smoking apps that exploited addiction for profit—filled with intrusive ads, aggressive pressure tactics, expensive subscriptions, and worst of all, selling user health data to third parties.
CosmoQuit is my answer: a simple, honest, free tool that respects your privacy and supports your journey without judgment.
Your data never leaves your device. No tracking, no analytics, no cloud storage.
We don't profit from addiction. No premium plans, no paywalls, ever.
No scare tactics, no guilt trips. Just calm, supportive guidance.
Your health journey is yours alone. We will never sell or share your data.
Cosmonika is an independent product studio focused on building privacy-first, user-respecting digital products. We believe technology should serve people, not exploit them.
Every product we build follows three core principles:
Data minimization and local-first architecture from day one.
No dark patterns, no manipulative design, no exploitation.
Building products that do good, not just make money.
Cosmonika started with a simple observation: too many apps in the health and wellness space were built to extract value from vulnerable users rather than genuinely help them.
Whether it's quit-smoking apps selling user data to insurance companies or meditation apps using psychological tricks to maximize subscriptions, the pattern was clear.
We decided to build differently. CosmoQuit is our first product—a proof that you can create helpful tools without compromising on ethics.
"Technology should empower people, not exploit their vulnerabilities."
