Common Questions
How do I delete my account?
Open the App, go to the You tab, then Settings > Delete Account. This permanently removes your account and all associated data. This action cannot be undone. You can also email us at support@lyph.app to request deletion.
What data does Lyph track?
Lyph tracks nutrition (meals and macros), workouts, mood and daily check-ins, habits, goals, and guided reflections. You can capture entries by typing, snapping a meal photo, or speaking. If you connect Apple Health, it can also include steps, sleep, activity, and more. Everything combines into a daily score to help you see your progress.
How do I connect Apple Health?
Go to the You tab > Integrations > Apple Health. You choose which categories to authorize — enable as few or as many as you like (for example steps, active energy, workouts, sleep, heart rate, height, and weight). You can change these permissions anytime in your device's Settings > Privacy & Security > Health.
Is my data safe?
Yes. Your data is encrypted and stored with row-level security, meaning no one else can access it. We don't sell your data, use it for advertising, or share it with data brokers. To power the AI coach, relevant context — and, if you connect Apple Health, summarized health metrics — is sent to OpenAI to generate responses; meal photos and voice recordings are analyzed by OpenAI but not stored by Lyph. See our
Privacy Policy for full details.
How does the AI coach work?
The AI coach uses your tracked data (nutrition, workouts, mood, check-ins, goals, and — if connected — Apple Health metrics) to provide personalized insights and suggestions. It's powered by OpenAI, accessed through a secure proxy, and can analyze meal photos and transcribe voice logs. Your data is not used to train AI models. Reasonable daily usage limits apply. AI advice is for informational purposes only and is not a substitute for professional guidance.
Does Lyph use my camera and microphone?
Only when you choose to. Lyph uses the camera and photo library when you capture a meal by photo or barcode, and the microphone when you log by voice. These photos and recordings are sent to OpenAI for analysis (for example, to estimate nutrition or transcribe your words) and are not stored by Lyph — only the resulting entry is saved.
Is Lyph free?
Yes. Lyph is currently free to download and use, with no in-app purchases or subscriptions.
What iOS version do I need?
Lyph requires iOS 16.0 or later.
I found a bug. How do I report it?
Email us at support@lyph.app with a screenshot and description of what happened. Include your device model and iOS version. You can also submit a bug report from within the App (You tab > Support). We fix issues quickly.
Can I use Lyph offline?
Yes. Lyph caches your data locally so you can log workouts, meals, moods, and habits offline. Your data syncs automatically when you reconnect.
