Privacy Policy

Last updated: October 24, 2026

Introduction

Welcome to FluidMacros ("App", "Service", "we", "us", or "our").

This Privacy Policy explains what information we collect when you use our mobile application, website, and related services, how we use and share it, and the choices you have — including how to delete your data.

We do not sell your personal information, we do not use it for advertising, and we do not track you across other companies’ apps or websites.

Information We Collect

Account Information

When you create an account, we collect:

• Email address and password (passwords are stored only in hashed form by our authentication provider)
• Name, if you choose to provide one
• Your profile settings: macro targets, meal plan, diet styles, and allergens you select
• If you use the target estimator: your sex, age, height, weight, activity level, and goal, saved so you can update them later
• Your focus and training answers (for example "less sodium" or "mostly lifting") and which nutrients you track, with any limits you set

Food, Nutrition, and Health-Related Information

To provide the Service we store the nutrition-related information you enter, which may be considered consumer health data under some laws:

• Your food log: foods you log, amounts, dates and times, and their calorie, macronutrient, sugar, sodium, fiber, and saturated fat values
• Recipes you paste, import, optimize, or save, and notes you add to them
• Snacks you save and dining-out orders you log
• Your grocery list: the items, amounts, and which recipes they came from
• Meal photos you choose to attach to food log entries
• If you pair a smart scale: the name you give it, a one-way hash of its pairing token, the weights it sends while you weigh food, and — if it has a camera — the photos it takes of your plate as you add food, used to identify what you added. Scale photos are stored privately and visible only to you

We use this information only to provide and improve the Service for you. We do not share it with third parties for advertising or marketing, and we do not sell it.

Camera and Photos

If you allow camera access, the camera is used only while you are scanning a barcode or taking a meal photo. Barcode scanning happens on your device. When you pick a photo from your library, the system photo picker gives us only the photo you choose — not access to your library. Meal photos are stored privately in your account and are visible only to you.

Location Information

If you allow location access, we use your device’s location while you use the App to find restaurants near you. Your coordinates are sent to our servers to look up nearby restaurant locations (and, if our database has nothing nearby, to OpenStreetMap’s public map servers); we do not store your location history. Location is optional — the App works without it, and you can type a city or ZIP code instead.

Information You Send Us

• Bug reports you submit, which include your description plus the app screen, app version, device model, operating-system version, and your account identifier
• Reports that a restaurant menu item is out of date
• If you submit a restaurant’s menu: your name, role, and contact email (used only to review the submission and contact you about it), plus the restaurant information you submit, which we may publish
• Emails and other support communications
• Your email address, if you join our waitlist on our website (with a one-way hash of your IP address, used only to block spam sign-ups)

Information We Do Not Collect

We do not currently use third-party analytics, advertising, or tracking tools in the App, and we do not access your contacts, microphone, or health data from Apple Health.

Features We’re Testing

When you tap a feature we’re still building — such as “Order groceries” on your grocery list — we record the tap, your device type, and, for grocery orders, the items on your list and the recipes they came from. We use this ourselves to decide what to build and to plan future grocery ordering, which may later work with shopping or delivery partners. We do not sell this information or share it with anyone; if a future grocery feature would send your list to a partner, it will ask you first.

How We Use Information

• Provide the Service: your profile, food log, recipes, and nutrition estimates
• Estimate nutrition for foods you type, scan, or import (see "Services That Process Your Data")
• Show restaurants and menu options near you
• Keep your data in sync across your devices
• Respond to bug reports, menu reports, and support requests
• Protect the Service against fraud, abuse, and unauthorized access
• Comply with legal obligations

Services That Process Your Data

We use the following service providers to operate the Service. They process data only on our behalf and only as needed to provide their service:

• Supabase (database, authentication, file storage, and server functions; data is hosted in the United States)
• Cloudflare (website hosting and security)
• Google (bug reports are stored in a Google Sheet that only our team can access)
• Anthropic (if your smart scale has a camera, our servers send its plate photos, the weight change, and the foods already on that plate to Anthropic’s Claude AI to identify what you added; your name and email are not sent)

We also send limited, non-identifying requests to public nutrition databases:

• Food names you type are looked up by our servers in USDA FoodData Central — the request contains only the food name, not your identity
• Barcodes you scan are looked up directly from your device in Open Food Facts — the request contains only the barcode number
• If you type a city or ZIP code instead of sharing your location, our servers look it up in the Open-Meteo geocoding service — the request contains only what you typed
• Recipe links you import are fetched from the recipe website by your device or our servers

Photo analysis: the App does not currently send meal photos to any AI service. If we add automatic photo estimates in the future, we will tell you which service processes your photos and ask for your permission before any photo is sent.

Legal Requirements and Business Transfers

We may disclose information when required by law, or when we reasonably believe it is necessary to protect our rights, our users, or the public, or to investigate fraud or security issues. Information may be transferred as part of a merger, acquisition, or sale of assets, in which case this Policy will continue to apply.

Data Retention and Deletion

We keep your account information, profile and body stats, food log, recipes, photos, and smart-scale readings and photos for as long as your account is active. You can delete individual food log entries, recipes, and photos at any time.

Restaurant submissions are kept while we review them and, once approved, for as long as the listing is in the Service; the submitter’s contact details are deleted with their account. Bug reports and support emails are kept for up to two years. Abuse-prevention counters are deleted within a day.

You can delete your account in the App under You → Settings → Delete account. This permanently deletes your account, profile, food log, saved recipes, and meal photos right away. Menu-item reports you sent are kept to fix restaurant data but are no longer linked to you. Backups held by our hosting provider are overwritten within their standard backup cycle.

If you can’t access the App, email hello@fluidmacros.com from your account’s email address and we will delete your account for you.

Data Security

Data is encrypted in transit and at rest by our hosting provider. Access to your data is restricted to your account by database access rules, and meal photos are stored in private storage. To prevent abuse we keep short-lived request counters keyed to your account or a one-way hash of your IP address; they are deleted within a day. No system is perfectly secure, and we cannot guarantee absolute security.

Your Rights and Choices

Depending on where you live, you may have the right to:

• Access the personal information we hold about you and get a copy of it
• Correct inaccurate information (most of it you can edit directly in the App)
• Delete your information (in the App, or by contacting us)
• Withdraw consent, for example by turning off camera or location access in your device settings
• Not be discriminated against for exercising these rights

To make a request, email hello@fluidmacros.com. We will verify the request comes from the account holder and respond within the time required by law (for most states, 45 days). You can appeal a decision by replying to our response. You may use an authorized agent to make a request; we may ask the agent for proof of your permission and ask you to confirm your identity with us directly.

Do Not Track and Global Privacy Control: we do not track you across other apps or websites and do not sell or share personal information, so there is nothing for these signals to opt you out of. We honor them anyway — if your browser or device sends a Global Privacy Control signal, we treat it as a request to opt out of any sale or sharing.

California Privacy Rights

If you live in California, the California Consumer Privacy Act (as amended by the CPRA) gives you the rights listed above — to know, access, correct, and delete your personal information, and not to be discriminated against for using them. In the past 12 months we have collected the following categories of personal information, from you and your device, for the purposes described in this policy:

• Identifiers: email address, name, account ID
• Commercial information: subscription status (billing itself is handled by Apple), your grocery list, and taps on features we’re testing such as grocery ordering
• Internet or device activity: app version, device model, and screen, sent with bug reports
• Approximate location: a city or ZIP code you type
• Audio/visual information: meal photos you attach
• Sensitive personal information: account login (email and password), health-related information (your food log, diet, allergens, body stats, and focus and training answers), and precise location while you search for nearby restaurants (not stored)
• Professional information: role and contact details, if you submit a restaurant’s menu

We disclose these categories only to the service providers listed above, for business purposes. We have not sold or shared (for cross-context behavioral advertising) personal information in the past 12 months, and we have no actual knowledge of selling or sharing information about anyone under 16. We use sensitive personal information only to provide the Service you request, so the right to limit its use does not apply. We do not disclose personal information to third parties for their direct marketing (California “Shine the Light” law).

Consumer Health Data Privacy Policy

This section applies to “consumer health data” under the Washington My Health My Data Act, Nevada SB 370, Connecticut law, and similar state laws. It describes:

• What we collect: your food log, recipes, saved snacks and dining orders, meal photos, smart-scale weights and plate photos, diet styles, allergens, body stats (sex, age, height, weight, activity level, and goal), any nutrient limits you set (sugar, sodium, fiber, saturated fat), and your focus and training answers (for example "less sodium" or "mostly lifting")
• Where it comes from: you, when you enter it, and your smart scale, if you pair one
• Why we collect it: only to provide the features you ask for — estimating targets, logging food, tailoring recipes and restaurant suggestions to your diet and allergens — and to keep the Service working and secure
• Who receives it: only the service providers listed above, which process it on our behalf. We do not sell it, use it for advertising, or share it with any other third party or affiliate
• We do not use geofencing around health care locations or any other places

You have the right to confirm whether we collect your consumer health data, to access it (including a list of every third party and affiliate that has received it), to delete it, and to withdraw consent. Most of it you can view and delete in the App; for anything else email hello@fluidmacros.com. If we deny your request you can appeal by replying to our response, and if the appeal is denied, Washington residents may contact the Washington State Attorney General at atg.wa.gov.

Children's and Teens' Privacy

The Service is intended only for adults ages 18 and older. It is not directed to children or teens, and we do not knowingly collect personal information from anyone under 18. If we learn that we have, we will delete that account and its data. If you believe a minor has created an account, contact us at hello@fluidmacros.com.

International Users

Our servers are located in the United States. If you use the Service from outside the United States, your information will be transferred to and processed in the United States.

Changes to This Policy

We may update this Privacy Policy from time to time. We will update the "Last updated" date, and for material changes we will let you know in the App or by email.
