## What is CellaLonga?

Fasting isn't a diet. It's your longevity lever — measured honestly, owned for life.

CellaLonga follows your body through the real metabolic journey of a fast: fed, glycogen, the metabolic switch, fat-burning, ketosis, autophagy, and deep autophagy — rendered as a living ring, not a countdown timer.

THREE LAWS OF HONESTY
Most fasting apps blur the line between what's known and what's guessed. CellaLonga never does:
• Estimated, refined, and measured are always labelled — never confused.
• Autophagy is always shown as an estimate. No consumer device can measure it directly, no matter what other apps claim.
• Ketosis is the only stage that can become "measured" — and only if you log a real ketone reading. Every source is cited, with its caveats.

YOUR OWN MIRROR
See honest, non-causal correlations between your fasting windows and how you actually feel, sleep, and recover — never a single statistic without the data behind it, never a claim before there's enough of it.

LONG FASTS, DONE RESPONSIBLY
24 to 72-hour fasts come with a real safety brief — hydration, warning signs, how to break a long fast gently — not just a longer timer.

OWN IT, DON'T RENT IT
One purchase unlocks full sources, measured mode, long fasts, your complete mirror, and unlimited history. No subscription. No guilt quizzes. No countdown pressure.

PRIVATE BY DESIGN
CellaLonga has no backend, no account, and collects nothing. Apple Health connection is entirely optional and only enriches what already works from a simple daily log.

CellaLonga is informational only and is not medical advice. Consult a clinician before attempting extended fasts, especially if you take medication or have a medical condition.
