FAQ
Common questions.
What is CBT-I?
CBT-I stands for Cognitive Behavioral Therapy for Insomnia — a structured, evidence-based approach that addresses sleep-related behaviors and thoughts. Simple CBT-I uses its principles in brief daily check-ins. It is not a clinical CBT-I program.
How does AI Daily Insight work?
Each morning, AI reviews your recent sleep entries, weekly trends, and CBT-I check-in answers. It generates a short insight with one practical action to keep in mind. It is not medical advice or a diagnosis.
Does this app replace medical care?
No. Simple CBT-I is a self-help sleep journal. It does not diagnose, treat, or cure any condition. If you have concerns about your sleep, consult a qualified healthcare professional.
What data does AI Daily Insight use?
It uses your sleep record (bedtime, wake time, sleep duration, etc.), recent trends, and daily CBT-I check-in answers. Personal memos are not sent to the AI.
Is an account required?
No. Your sleep data is stored on your device. You can back it up to a file and import it on another device without creating an account.
