Privacy Policy

MacroJar · Effective 1 November 2026

Who we are

MacroJar is made by Dollarsom (“we”, “us”). This policy explains what information MacroJar uses, where it goes and the choices you have. If you have any questions, email us at dollarsom2@gmail.com.

The short version

•
Your food diary, goals and body details stay on your phone. We don’t receive them.
•
An account is optional. If you sign in with Google or Apple, we keep your name, email and a count of your daily photo estimates.
•
Meal photos you choose to scan are sent to Google’s Gemini service for an estimate and are not saved by us.
•
If you subscribe to Premium, Apple or Google take the payment and RevenueCat manages the subscription. We never see your card details.
•
We don’t sell your information, show ads or use analytics or tracking tools.
•
You can delete your account at any time in Settings.

Information that stays on your phone

When you use MacroJar, it saves the following in the app’s own storage on your phone:
•
your answers during setup (sex, age, height, weight, activity level and goal) and your display name
•
your daily calorie and nutrient goals
•
the meals and foods you log or save
•
small copies of meal photos you log, so they appear in your diary
This information is not sent to us. It stays on your phone until you use Settings → Erase data on this phone, or uninstall the app. Your phone’s own backup (such as iCloud or Google backup) may include it, depending on your phone’s settings.

Your account (optional)

You can use MacroJar without an account. Photo estimates need one. If you sign in with Google or Apple, we receive your name, email address, profile picture link (Google only) and an account ID. If you sign in with Apple and choose to hide your email, we receive a private relay address from Apple instead.
We also keep a count of how many photo estimates you’ve used each day, to apply the daily limit.
If you subscribe to MacroJar Premium, your subscription (which plan, when it started and when it renews or ends) is linked to your account ID through RevenueCat, so Premium works on every phone you sign in on. Payment is handled by Apple or Google; we never receive your card details.
We use this information only to sign you in, provide photo estimates and Premium, and keep the service fair for everyone. Accounts are stored with our account provider, Supabase.

Meal photo estimates

When you take or choose a meal photo for an estimate, the app makes a smaller copy and sends it over an encrypted connection to our server. Our server sends it to Google’s Gemini service, which returns an estimate of the food, the portion and its nutrition.
Our server doesn’t save your photo. We ask Google not to store the request, and under Google’s terms for paid Gemini services, Google doesn’t use it to improve its products. Please don’t include people or personal documents in your food photos.

Food search and barcodes

•
When you search for a food, your search words are sent through our server to USDA FoodData Central, the U.S. government’s food database.
•
When you scan a barcode, the barcode number is looked up directly at Open Food Facts, a free, community-run food database.
As with any internet request, these services can see your device’s IP address. We don’t send them your name, email or diary.

Camera and photos

MacroJar uses your camera only while the scanner is open, to read barcodes and take meal photos, and your photo library only when you choose a photo. It doesn’t use your microphone, location or contacts.

What we don’t do

•
We don’t sell or rent your information.
•
We don’t show ads.
•
We don’t use third-party analytics, advertising or tracking tools.
•
We don’t share your information for marketing.

Service providers

These companies process information on our behalf, only to provide their part of MacroJar:
•
Supabase — stores accounts and daily photo-estimate counts
•
Expo (EAS Hosting) — runs our server
•
RevenueCat — manages Premium subscriptions
•
Google — Gemini photo estimates, Sign in with Google, and Google Play payments
•
Apple — Sign in with Apple, and App Store payments
•
USDA FoodData Central — food search
•

Their servers may be in other countries than yours, including the United States. They have their own privacy policies.

How long we keep information

•
Account and daily photo-estimate counts: until you delete your account.
•
Subscription records: kept by RevenueCat, Apple and Google as long as needed for accounting and the law.
•
Information on your phone: until you erase it or uninstall the app.
•
Meal photos: not kept by us.
Our hosting and account providers may keep short-lived technical logs, such as IP addresses and request times, for security and reliability.

Legal bases (EU and UK)

Where EU or UK data protection law applies, we use your information to provide the features you ask for (contract), to keep the service secure and fair, such as the daily limit (legitimate interests), and with your permission for camera and photo access (consent), which you can withdraw in your phone’s settings.

Your choices and rights

•
Delete your account: Settings → Delete account. This permanently deletes your account and photo-estimate counts from our servers.
•
Erase your diary: Settings → Erase data on this phone.
•
Signing out keeps your diary on your phone.
Depending on where you live (for example in the EU, UK or California), you may have the right to access, correct, delete or export your information, to object to some uses, and to complain to your data protection authority. To make a request, email dollarsom2@gmail.com. We’ll reply within 30 days.

Children

MacroJar is not meant for children under 13 (or the minimum age for digital services where you live), and we don’t knowingly collect information from them. If you believe a child has created an account, email us and we’ll delete it.

Security

Information is sent over encrypted (HTTPS) connections, our service keys are kept on our server and never in the app, and account data is protected by our provider’s access rules. No system is completely secure, but we work to protect your information.

Changes to this policy

If we change this policy, we’ll update this page and the date at the top. For important changes, we’ll also let you know in the app.
