Privacy Policy for Daylog Health
Effective date: September 8, 2026
Intro paragraph
(Use a Text block)
Hinners IT & Software Consulting ("we," "us," "our"), doing business as Hinners Software, operates the Daylog Health mobile application (the "App"). This Privacy Policy explains what information we collect through the App, how we use it, and the choices you have.
1. Information We Collect
Profile & body metrics
Age and biological sex
Height, weight, and your Imperial/Metric unit preference
Blood glucose, blood pressure, oxygen saturation, body temperature, and water intake, when you enter them or sync them from a connected source
Your calorie and carbohydrate targets and daily logs
Meal photos
When you photograph a meal for carb/calorie analysis, that image is sent to Google's Gemini API for processing and returns the nutritional estimate shown in the App.
Connected health data sources
If you choose to connect them, we access data made available through:
Google Health Connect — weight, height, blood glucose, and other body metrics synced from apps or devices you've authorized on your device
Dexcom — glucose readings, when you connect a Dexcom account directly
MedM Health — glucose device data synced through Health Connect
You control these connections in your device's Health Connect permissions at any time.
Subscription & payment information
Daylog Health's premium features (AI meal scanning, glucose sync) are sold via subscription through Google Play Billing. Google processes your payment; we receive confirmation of your subscription status but not your full payment card details.
Diagnostic & app information
We use Firebase Remote Config to manage which AI model version the App uses, and the App displays its version number on the About screen.
2. How We Use Your Information
To analyze meal photos and estimate carbohydrate and calorie content
To calculate your daily calorie/carb targets and show progress on the Today's Summary and Daily Target & Strategy cards
To display your logged and synced health metrics back to you
To send in-app warnings when you're near or over your daily calorie target
To process and manage your subscription
To maintain, secure, and improve the App
3. How We Share Your Information
We share information only as needed to provide the App's features:
Google Gemini API — meal photos and related prompts, to generate nutrition analysis
Google Health Connect / Dexcom / MedM Health — to read the health data you've authorized
Google Play Billing — to process subscription payments
We do not sell your personal or health information. We do not share it with advertisers.
4. Data Retention
We retain your logged data for as long as your account is active, so you can track trends over time. You can delete your data or your account at any time from within the App's settings, or by contacting us using the details below.
5. Data Security
We use reasonable administrative and technical safeguards to protect your information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
6. Your Choices & Rights
You can disconnect Health Connect, Dexcom, or MedM Health at any time in your device settings
You can request access to, correction of, or deletion of your data by contacting us
Depending on where you live, you may have additional rights under laws such as the GDPR or applicable U.S. state privacy laws
7. Medical Disclaimer
Daylog Health is not a substitute for professional medical advice, diagnosis, or treatment, as acknowledged during onboarding. Always consult a qualified healthcare provider regarding your diabetes management or any medical condition.
8. Children's Privacy
Daylog Health is not directed at children, and we do not knowingly collect personal information from children under 13 (or the relevant age of digital consent in your region). If you believe a child has provided us with personal information, please contact us so we can delete it.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We'll update the effective date above when we do, and, for material changes, we'll provide additional notice in the App.
