uzznat@gmail.comHow accurate is the AI calorie estimation?
Photos give a rough estimate (~80% accurate for clear single dishes). For best results, mention what's in the dish or estimate the portion size. You always have the choice whether to log the AI's estimate or not.
Does FitAI work offline?
Most features need internet (the AI Coach especially). Logging meals/workouts you've already saved as Quick Log items works offline.
How is my data stored?
All your tracking data lives on your device. Your profile syncs to Firebase (Google's secure cloud) so you can sign in on multiple devices. Progress photos NEVER leave your phone unless you tap "Get AI Check".
Can I cancel my streak protection?
Streak shields auto-protect you once per shield. They don't auto-renew. You can earn more by completing weekly challenges.
How do I delete my account?
Go to Settings → Profile → "Delete Account". This permanently removes your profile + all synced data. Cannot be undone.
I'm under 18 — can I use FitAI?
Users under 18 should consult a parent and a doctor before using any fitness tracking app. FitAI is not designed for medical use.

The AI Coach feature is powered by Anthropic's Claude API. Before any data is sent for the first time, we ask for your explicit consent inside the app. If you accept, the following information is sent to Anthropic over HTTPS each time you message the coach:
What is NOT sent to Anthropic: your email, your password, your progress photos, your full daily history, or any data from other users.
How Anthropic uses this data: per Anthropic's API terms, the data you send is used solely to generate the coach's reply. Anthropic does not train its models on your data. See Anthropic's privacy policy.
You can use FitAI without enabling the AI Coach. If you decline the consent prompt, no message data ever leaves the app.
FitAI is not intended for children under 13. We do not knowingly collect data from children under 13. Users under 18 should have parental approval.
We may update this policy. The "Last updated" date at the top will reflect changes. Material changes will be notified in-app.

FitAI provides AI-generated fitness, workout, and nutrition suggestions for informational purposes only. It is not a substitute for advice from a licensed medical doctor, certified personal trainer, or registered dietitian. Always consult a qualified professional before starting any new exercise program, changing your diet, or taking supplements.
All workout plans, food estimates, calorie counts, photo analysis, and coaching messages are produced by artificial intelligence (Claude by Anthropic). AI can make mistakes — values may be inaccurate, exercises may be unsuitable for your body or skill level, and analysis may misread a photo. You are responsible for evaluating every recommendation before acting on it.
You use FitAI entirely at your own risk. The creator of FitAI is not liable for any injury, illness, allergic reaction, weight gain or loss, mental distress, equipment damage, financial loss, or any other harm — physical, psychological or financial — resulting from your use of the app or from following any AI-generated suggestion.
You must be at least 13 years old to use FitAI. Users under 18 must have parental approval. Do not use this app if you have a heart condition, diabetes, eating disorder, are pregnant or breastfeeding, recovering from injury, or any other medical condition without consulting a doctor first.
You are responsible for the accuracy of the information you provide and for safeguarding your account credentials.
We may suspend or terminate access for users who violate these terms. You can delete your account at any time from Settings.
