Privacy Policy

Last updated: September 19, 2026

This Privacy Policy explains how MyMacrosFast ("MyMacrosFast," "we," "us," or "our") collects, uses, and shares information when you use the MyMacrosFast mobile application (the "App"). MyMacrosFast is operated by Hadi Ramlaoui, an individual based in California, USA.

This policy describes our data practices. It does not replace any separate permission required before collecting or sharing your information.

1. Information We Collect

Information you provide directly

Meal photos and descriptions. When you log a meal, you may take or upload a photo of your food, or type a text description of it. We use this to estimate the food items, portion sizes, and macronutrient/calorie content of your meal.
Maccy conversations. We process messages you send, recent conversation context, and relevant draft or logged meal details to respond to your requests. Avoid including personal details that are not needed for your request.
Account information. If you choose to sign in with Google or Apple, we receive basic identity information from that provider (such as your name and email address, as permitted by your privacy settings with that provider) to create and secure your account. When you sign in with Apple, we also keep the sign-in token Apple issues to us, solely so that we can revoke your Sign in with Apple authorization with Apple if you later delete your account (Apple requires this). You can also use the App without signing in — in that case, your data is tied to a randomly assigned anonymous account in Supabase. Session credentials are kept on your device, but logged meals, uploaded photos, and saved goals are stored on our servers, not only on your device. Losing access to that session may prevent recovery of anonymous data.
Body and goal details. If you use the Daily Goal feature, you can enter your sex, age, height, weight, activity level, and goal (for example, lose or maintain weight). We use these only to calculate your suggested daily calorie and macronutrient targets. They are stored with your account so your targets follow you across devices. You can change them at any time from the Account screen, and they are removed with everything else when you delete your account or data.

Information generated by the App

Logged entries. The meals you log, including estimated macros (protein, fat, carbs, calories), food names, portion weights, and timestamps.
Barcode scans and food searches. When you scan a product barcode or search the food database, the barcode number or your search term is used to look up that product and its nutrition information from external food-data providers (see "How We Share Information" below).
Subscription status. If you subscribe to MyMacrosFast Premium, we record whether your subscription is active so the App can unlock Premium features. We receive this from Apple through RevenueCat (see below); we never see your payment card details.
Technical/diagnostic data. When enabled, Sentry collects error, crash, and sampled performance information, such as device type, OS version, timing, and the part of the App that failed. Reports may include request or error context. We do not deliberately attach your name or email to reports, and we remove authorization headers before sending error events. Our backend and infrastructure providers also process network and operational information to run and secure the service.

We do not currently use behavioral analytics or advertising tracking of any kind.

2. How We Use Information

We use the information described above to:

Analyze meal photos/descriptions and estimate their macronutrient and calorie content
Look up product and nutrition information for barcodes you scan and foods you search for
Store your logged meals so you can review your history
Sync your data across devices when you're signed in
Maintain, secure, and improve the App
Diagnose and fix technical problems

3. How We Share Information

We do not sell your personal information. We share information only as necessary to provide the App:

Anthropic (the maker of the Claude AI models): meal photos and text descriptions you submit, and the messages you send to the Maccy assistant (together with recent conversation context and relevant draft or logged meal details), are sent to Anthropic's API solely to identify food items, estimate macros, and answer your request. Anthropic processes this data as our service provider under their commercial API terms and does not use API inputs or outputs to train its models by default. See Anthropic's commercial data-use policy. Anthropic generally deletes API inputs and outputs within 30 days, with exceptions such as safety enforcement and legal obligations, as described in its retention policy.
Supabase: our backend infrastructure provider. Supabase hosts our database, file storage, and authentication systems, and stores your account data, logged entries, and meal photos on our behalf.
Food-data providers (Open Food Facts and USDA FoodData Central): to identify a scanned or searched food and its nutrition, we query public food databases. When you scan a barcode, your device contacts Open Food Facts directly, so that provider may receive the barcode number and standard network information (such as your IP address and a general app identifier). Food searches — and barcodes not found in Open Food Facts — are sent through our backend to USDA FoodData Central, which receives the search term or barcode but not your device's IP address. We do not send your account information, meal history, or any personal identifiers to these providers.
Google / Apple: if you sign in with Google or Apple, those providers share basic identity information with us as part of the sign-in process, subject to their own privacy policies.
Apple and RevenueCat: if you purchase a subscription, that transaction is handled by Apple's In-App Purchase system. We use RevenueCat to manage subscription status: it receives your App Store transaction details and a random app user identifier (your account's internal ID, not your name or email) so that your subscription can be matched to your account and restored on a new device. We do not see or store your payment card details — Apple handles billing directly.
Sentry: our crash-reporting provider (see "Technical/diagnostic data" above). It processes error, crash, and performance information, which may include request or error context.
Legal requirements: we may disclose information if required by law, or to protect the rights, property, or safety of MyMacrosFast, our users, or others.

4. Data Retention & Deletion

We retain your saved meals, photos, goals, and account information to provide your account and history until you delete them or request deletion. Stopping use of the App or uninstalling it does not by itself delete data stored on our servers.

Moving anonymous data to an account. If you start using the App without signing in and later sign in with Google or Apple, the App asks whether to bring the meals from your anonymous session over to your account. If you choose to, that data (meals, photos, pinned meals, and — only if your account has none yet — your goal and body details) is reassigned to your signed-in account. If you choose not to, it stays under the anonymous session and is not linked to your account.

You can permanently delete your data at any time from the Account screen in the App:

If you're signed in, "Delete My Account and Data" permanently deletes your account, every meal you've logged, any photos you've uploaded, your goal and body details, and — if you signed in with Apple — revokes your Sign in with Apple authorization and removes the token described above.
If you're using the App anonymously, "Delete My Data" does the same for your anonymous session's data.

This deletion is permanent and cannot be undone. Data is removed from the live account, meal, and photo systems when deletion completes. Backup copies may remain until the applicable backup retention period expires. Limited operational, security, audit, or transaction records may remain where needed for security, legal obligations, or billing. In-app deletion does not automatically erase records held separately by Apple, RevenueCat, or other providers under their retention policies. Deleting your account does not cancel an active subscription — Apple manages billing, so cancel it in your Apple ID subscription settings (the App links you there before deletion).

5. Children's Privacy

The App is not directed at children under 13, and we do not knowingly collect information from anyone under 13. If you believe a child under 13 has provided us with information, contact us at the email below and we will delete it.

6. Your Choices & Rights

Regardless of where you live, you can contact us at any time to:

Request a copy of the information we hold about you
Request correction of inaccurate information
Request deletion of your information (or use the in-app deletion feature described above)

7. Data Security

We use reasonable technical and organizational measures to protect your information, including row-level database security to restrict access between users. Authorized backend services and providers also process data as described in this policy. However, no method of transmission or storage is 100% secure, and we can't guarantee absolute security.

8. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we'll update the "Last updated" date above. We will provide additional notice or obtain consent where required by applicable law.
