Your logs stay yours
Meals, photos, reflections, and chat are for your account — to help you remember and compare your week. We do not sell personal information.
Trust
Your food story stays yours.
Fyll is built for private pattern tracking — your meals, your reflections, your history. Not ads. Not data resale. Not training on what you ate.
Not training on your meals
Fyll does not use your meal photos or personal data to train its own AI models. Your food story is not product fuel.
Health data is optional
Connect Apple Health or sleep summaries only if you want. The app works without them — no connection required to log or see patterns.
You stay in control
Edit meal estimates before saving. Update profile details anytime. Export where available, or delete your account from Settings.
Honest limits
What we will tell you straight.
Trust also means not overselling. Two things worth knowing up front — so you can use Fyll with clear eyes.
Estimates are starting points
Photos can miss portions and hidden ingredients. Fyll shows drafts you can fix — not ground truth you have to accept.
Patterns, not medicine
Fyll helps you spot repeats in what you logged. It does not diagnose, prescribe, or replace a clinician.
Phine's role
Warm, observant, grounded in what you logged.
Phine is the memory layer — she helps you notice repeats across your meal log, compare similar days, and ask better questions about your week. She works from what you entered: meals, edits, timing, and how you said you felt.
She is not a medical authority or a diet coach. She does not see hidden ingredients, read your mind, or speak for your body. She reads your log with you.
