Answers to common questions about FeuFitness, plus how to reach us directly if you need more help.
The fastest way to reach us is the Help / Send Feedback form inside the app: open FeuFitness, go to Settings, and choose Help / Send Feedback. Pick the option that best matches your issue (Technical Issue, Question, or General Feedback) and, if you'd like a reply, leave a contact email — it routes straight to us.
How do I cancel or manage my Premium subscription?
Premium is billed through your Apple ID via the App Store, so cancellations and billing changes are handled entirely by Apple, not us. On iPhone: open Settings → [your name] → Subscriptions, select FeuFitness, and choose Cancel Subscription. Changes take effect at the end of your current billing period.
How do I turn on Cloud Sync?
FeuFitness works fully without an account. If you'd like your data to follow you across devices, create an account from Settings — this turns on Cloud Sync. Without an account, your data stays only on your device.
I forgot my password — how do I get back in?
Go to Settings, and on the Cloud Sync sign-in form, tap Forgot password? and enter your account email. We'll send you a reset link. If you've never created an account (no Cloud Sync), there's no password involved — just open the app as usual.
I upgraded to Premium, but it's not showing on this device
This usually happens after reinstalling the app or switching devices. Open any "Go Premium" prompt (for example, the Premium card on the Home tab) and tap Restore Purchases near the bottom — this reconnects your existing subscription via your Apple ID, with nothing to pay again.
How do I delete my account and data?
Use the in-app Help / Send Feedback form and let us know you'd like your account deleted. We action deletion requests within 6-8 weeks. You can also delete individual weight, food, or water entries yourself at any time within the app.
My step count isn't showing — what's wrong?
Step tracking needs permission to read your phone's motion data. On iPhone, go to Settings → Privacy & Security → Motion & Fitness and make sure FeuFitness is turned on. On Android, check Settings → Apps → FeuFitness → Permissions → Physical Activity.
Can I switch between metric and imperial units?
Yes — height and weight each have their own unit toggle (metric/imperial), shown wherever you enter them, in onboarding, Settings, or the Weight tab. They're independent, so you can mix units if that's how you naturally think about your numbers.
How is my BMI and calorie target calculated?
BMI uses the standard WHO formula (weight ÷ height²), with ethnicity-adjusted category cut-offs where applicable. Calorie targets use the Mifflin-St Jeor equation based on your height, weight, age, and sex. Full sourcing and citations are on the Weight tab.
How accurate are the AI features (AI Meal Scan, Coach Lumi)?
They're general, AI-generated estimates meant to help with day-to-day tracking — not medical or professional nutrition advice, and they can occasionally be inaccurate or incomplete. Calorie figures throughout the app are typical estimates for guidance, not verified nutritional data. If something looks clearly wrong, you can always log it manually instead.
Is my data private?
Most of your data stays on your device by default and is never sent anywhere unless you turn on Cloud Sync. We don't sell your data, run ads, or use third-party analytics. Full details are in our Privacy Policy.
What languages does FeuFitness support?
English, Spanish, Arabic, Hindi, Māori, Russian, Samoan, Urdu, and Chinese — including right-to-left layout for Arabic and Urdu. Change it anytime in Settings → Language.
Open the app, go to Settings → Help / Send Feedback, and send us a message. If you'd like a reply, include a contact email — we read every submission.
