Privacy Policy

What Sphere is

Sphere is a food and calorie tracking app made by Upstory. This policy explains what data the app collects, why, and what happens to it. The short version: your data is used to run the app for you, and we don't sell it to anyone.

Data you give us

• Account details — your email address and name when you create an account (via email, Apple, or Google sign-in).
• Food logs — the meals, portions, and water you record, including photos you choose to analyze.
• Body and goal data — height, weight, weight history, age, biological sex (optional), activity level, and nutrition goals you enter during onboarding or in settings. This is used solely to compute your calorie and macro plan.

How food photos are processed

When you snap a photo of a meal, the image is sent to our servers and processed with OpenAI's API to estimate its nutrition. Photos are used only to produce your food log entry. They are not used to train AI models.

Apple Health

Connecting Apple Health is optional. If you enable it, Sphere writes your logged nutrition to Apple Health and reads weight and activity data to keep your plan in sync. Health data stays between your device, your iCloud, and your Sphere account — we never share it with third parties, and we never use it for advertising.

Analytics

We track a small set of product events (such as account creation and whether logging streaks form) using PostHog, tied to your account, so we can tell whether the app is actually helping people build a habit. We do not track your food choices for advertising, and we do not use third-party ad networks.

Where your data lives

Your account and logs are stored with Supabase (our database provider). Payments and subscriptions are handled entirely by Apple through the App Store — we never see your payment details.

What we don't do

• We don't sell your personal data.
• We don't show ads or share data with ad networks.
• We don't use your photos or health data to train AI models.

Deleting your data

You can delete your account and all associated data by contacting us at support@getsphere.io. Deletion is permanent and covers your account, food logs, weight history, and photos.

Children

Sphere is not directed at children under 13, and we do not knowingly collect data from them.

Changes to this policy

If we make material changes, we'll update this page and the date above. Questions? Email support@getsphere.io.
