1About this app

Let's Talk Macros is a food and workout tracking app built and operated by Peach Haze Studio LLC, an independent developer. This policy explains what information the app collects when you use it, why, and what happens to it. It applies to the Let's Talk Macros mobile app and its backend service.

2Information you provide

Using the app means logging things about yourself, by design. That includes:

• Food logs: what you ate, how much, when, and the calorie/nutrient breakdown, whether typed, tapped in manually, spoken, scanned from a barcode, or looked up by name from an external nutrition database (see Section 8).
• Custom foods and recipes you create, including their nutrition information.
• Daily and per-nutrient goals you set (calories, protein, or any other tracked nutrient).
• Body weight entries, whether typed in directly or imported from Apple Health (see Section 7). Both are treated the same way once logged.
• Optional body profile details: age, biological sex, height, activity level, and a target weight/pace. These are used only to estimate a calorie target. This is entirely optional, and the app works without it.
• Exercise and workout logs, including sets, reps, weight, duration, and distance.
• Shopping list items you add.
• The text of conversations you have with the app's conversational logging feature ("Let's Talk"), whether typed or spoken.

3Account & sign-in

You need to sign in to use Let's Talk Macros, using either Sign in with Apple or Sign in with Google. We use Clerk, a third-party authentication provider, to handle this. We never see or store a password, and we don't offer our own email/password sign-in.

Depending on which method you choose, Clerk may receive your name and email address from Apple or Google to set up your session. On our side, we store only the account identifier Clerk gives us, and every piece of data described in Section 2 is tied to that identifier. This is what keeps your logs, foods, weight, and conversations separate from every other person using the app. Governed by Clerk's privacy policy.

4Information collected automatically

We don't use analytics, advertising, or tracking services of any kind. Our hosting provider (Railway) automatically logs standard technical information common to any web service, such as IP address, request timestamps, and error logs, as part of running the server. This is used only to operate and troubleshoot the service, never to build a profile of you.

5Voice recordings

There are two separate places you can speak to the app, and they work differently:

• "Let's Talk," the main voice feature, and the "Let's Talk" wake word use your device's own built-in speech recognition. Your speech is turned into text on the phone. No audio is ever saved to a file, sent to our servers, or sent to any other company. Only the resulting text goes on to be understood as a logging request (Section 8).
• The small microphone on the manual Log Food / Log Recipe screens is the one used to fill in an amount like "two cups." It does record a short clip and send it to OpenAI's speech-to-text service. That audio is held only in memory for the length of the request. Our server never writes it to disk or saves it in any database, and it's discarded as soon as the text comes back.

6Camera & barcode scanning

The app's barcode scanner uses your device's camera to read a barcode on your device. No photo, video, or camera image is ever captured, stored, or transmitted. The app only reads the barcode number itself, which is then looked up against our food database and, if needed, the public Open Food Facts database (see Section 8).

7Apple Health

If you turn on the optional Apple Health connection (Settings → Apple Health), the app can read your step count, floors climbed, walking and running distance, active energy burned, heart rate, and body weight from Apple's Health app on your device, and can write your logged body weight back to Health. A dedicated screen explains exactly what's read and written before iOS's own permission prompt ever appears, and you can turn access off at any time in iOS Settings → Privacy & Security → Health.

Steps, floors climbed, distance, active energy, and heart rate are read live from your device each time the app shows them. They are never sent to or stored on our servers. Body weight works differently. If you choose to import a weight you already have in Health (for example, from a smart scale), it's saved to our backend the same way as any weight you type in yourself (Section 2). Any weight you log in the app is, in turn, written to your device's Health app. Weight is the only Health data type this app ever writes.

8Third-party services

To provide its features, the app sends specific, limited information to these services:

We don't share your information with anyone else, and we don't sell it to anyone, ever.

9How we use your information

• To store and show you your own logs, totals, trends, and history.
• To power conversational and voice logging, as described above.
• To compute things you've asked for, like an estimated calorie target, a weekly report, or a strength milestone's progress.
• To operate, maintain, and troubleshoot the service.

We do not use your information for advertising, and we do not build any profile of you beyond what the app itself shows you.

10Data storage & security

Your data is stored in a database on our hosting provider's infrastructure (Railway) and transmitted using HTTPS encryption in transit. Every request to our backend must come from a signed-in account (Section 3), and every query is scoped to that account. Another person using this app cannot see your logs, foods, weight, or conversations, and you cannot see theirs.

11Retention & deletion

We keep your data for as long as your use of the app is active. Deleting a food, log entry, or recipe within the app removes it permanently. Logged history is never silently altered when you edit the underlying food later (that's how the app's snapshot accuracy works). To request deletion of your account and data entirely, contact us at the email below and we'll remove it.

12Children's privacy

Let's Talk Macros is not directed at children, and we do not knowingly collect information from anyone under 13. If you believe a child has provided us information, contact us and we'll delete it.

13Your choices

• Voice logging and barcode scanning are both entirely optional. You can log everything by typing or tapping instead.
• The Apple Health connection is entirely optional, and can be turned off at any time in iOS Settings → Privacy & Security → Health.
• The body-profile fields used for the calorie estimator are optional and can be left blank.
• You can delete individual logs, foods, or recipes at any time within the app.
• You can request a copy or full deletion of your account and data by contacting us.

14Changes to this policy

If this policy changes in a meaningful way, we'll update the effective date above. We'd encourage checking back here occasionally, especially while the app is in active early development.
