Frequently Asked Questions
The Delta score is your overall impact number — a composite of the Planet, Health, and Money scores. A positive delta means your choice is trending better than your 7-day average. A negative delta means it's below your baseline. Think of it as a net score that rewards improvement over time, not perfection in isolation.
Each score is generated by an AI model that analyzes the image you submit and scores it on a scale of 0–100 across three dimensions:
- 🌍 Planet — environmental impact: estimated carbon footprint, packaging waste, production methods, and sourcing
- 💚 Health — nutritional quality: whole ingredients, processing level, nutrient density, and dietary balance
- 💰 Money — cost efficiency: value relative to nutritional content and portion size
These are AI estimates based on visual analysis, not lab tests. They're designed to give directional guidance, not exact measurements.
No. Daily Delta scores are AI-generated estimates for informational purposes only. They are not a substitute for medical, nutritional, or dietary advice from a qualified professional. Results may vary depending on the image quality, lighting, and content of your submission.
AI analysis depends heavily on image clarity and what's visible in the frame. Blurry photos, cluttered backgrounds, or partially visible items may produce less accurate results. For best results, take a clear photo in good lighting with the item centered in the frame. You can retake the scan at any time.
Yes. Your scan history, scores, and account data are stored in the cloud, not on your device. As long as you sign in with the same email and password, everything will be there when you log back in.
You can delete your account directly in the app by going to Settings → Delete account & data. This will permanently remove your account and all associated data. Alternatively, email [email protected] and we will process the deletion within 30 days.
We collect your email address, the images you submit for analysis, and the scores generated from those images. We do not collect your location, contacts, or any sensitive device data. See our full Privacy Policy for details.
Your images are sent to OpenAI's API for analysis and stored in our cloud infrastructure (Supabase). We do not sell your images, share them with advertisers, or use them to train AI models. Images are retained for up to 90 days and then deleted automatically.
Free accounts get 3 scans per day. Your scan count resets at midnight. Pro subscribers get unlimited scans with no daily cap.
Daily Delta is designed to analyze:
- Plated meals and home-cooked food
- Grocery items and packaged food products
- Restaurant receipts and food purchases
- Grocery receipts
The AI will do its best with whatever you submit, but results are most accurate with clear food-related images.
You've reached your daily scan limit for the free tier (3 scans/day). The button will become active again the next day when your count resets. Upgrading to Pro removes this limit entirely.

Not yet. Daily Delta is currently Android-only. iOS support is on the roadmap but does not have a confirmed release date.
First, try closing and reopening the app. If the issue persists, try signing out and back in. If you're still having trouble, email [email protected] with a description of the issue and your device model. Screenshots are always helpful.
Daily Delta needs camera access to take photos directly, and photo library access to let you choose existing images for analysis. We only access photos you explicitly select — we do not scan or access your full photo library in the background.
