Effective Date: September 4, 2026
At Healthness, your privacy is a priority. This Privacy Policy outlines how we collect, use, share, and protect your personal information when you use our app. Please take a moment to read and understand our practices regarding your personal data. By using Healthness you agree to the practices described here.
Healthness is an app designed to help users track their calorie, macronutrient, and micronutrient intake, log water and exercise, record gym workouts, track intermittent fasts and rate their energy after each fast, follow their sleep, monitor progress toward fitness goals (such as losing or gaining weight), log meals via photo (analyzed by AI), by scanning a product barcode, or by photographing a nutrition or supplement label, maintain a daily supplement stack, ask questions of an AI nutrition assistant ("Coach"), and optionally share that progress with friends and family who also use the app. Healthness can optionally read from Apple Health so that your sleep and the energy you actually burn drive the app instead of an estimate. The app collects personal and health-related data to provide personalized fitness goals and the features described below.
When you create a regular account we collect:
You may also continue anonymously without an email or password. In that case Healthness creates a device-only anonymous user ID via Firebase Authentication. No personally identifiable information is collected for anonymous accounts beyond the data you choose to enter (age, weight, etc.).
Sleep in Healthness comes from Apple Health; the app does not measure sleep itself and shows nothing here unless you connect Apple Health. When you do, we store a nightly summary against your account: the date, time asleep, bedtime, wake time, the time spent in each sleep stage where your device records stages, and the sleep score Healthness computes from those figures. See Section 3 for how Apple Health data is handled, and Section 6 for the opt-in that lets a friend see your sleep.
If you add supplements to your stack, we collect:
Your conversations with Coach are stored on your device only, in the app's private storage. We do not keep a copy of your chat history on our servers. Each message you send is transmitted to our backend and forwarded to Anthropic to generate that reply — see Section 7 for exactly what accompanies it. We do record, against your user record, how many Coach messages and AI scans you have used in the current period, so that the free and Premium quotas can be enforced. Deleting a conversation in the app removes it from your device.
Healthness records a most-recently-active timestamp on your user record, along with the kind of action that most recently updated it (water, exercise, food, fast, profile, or simply opening the app). This signal is used to sort the Sharing screen by recency. Friends you have connected with can see the timestamp (e.g., "active 5 min ago") on your card in their Sharing screen; the specific action type is not displayed to friends.
If you connect with another user, we record the friendship link (a "Match"). When either party blocks the other or removes the friendship, the link is deleted from our database immediately.
If you grant notification permission, Apple Push Notification service provides us with a device token via Firebase Cloud Messaging. We use this token to deliver friend-request and meal-reaction notifications. The token is stored against your user record. You may revoke notification permission at any time in iOS Settings.
Healthness offers an optional Premium subscription via Apple's StoreKit. We receive entitlement and transaction status from Apple to unlock premium features. We do not receive or store your payment-card details — those are handled entirely by Apple.
If you submit a report against another user or a meal, we record the reporter's user ID, the reported user's ID, an optional meal ID, the chosen reason, and a timestamp. Block records are stored privately in your account.
We may collect anonymous crash reports and basic usage analytics through Firebase to improve app stability and quality. This data is not linked to your name or email and is never sold or used for advertising.
Healthness can read data from Apple Health so that your sleep and the energy you actually burn drive the app instead of an estimate. Connecting Apple Health is optional. The app asks for permission the first time you choose to connect it, and it works without it.
When you grant permission, Healthness reads the following data types:
Healthness never writes to Apple Health. Access is read-only; the app does not create, modify, or delete any sample in your Health database.
Background delivery. Healthness uses HealthKit background delivery so that a night's sleep recorded at 6 a.m. is available when you open the app. The app is woken only for Sleep Analysis, Active Energy, and Resting Energy — the types the sleep card and your calorie goal are built on — and only to read them.
Where this data goes. Sleep summaries, daily energy figures, and your weight are stored in your private Firebase (Google Cloud Firestore) account record, so the same information is available on the Android version of Healthness and survives reinstalling the app. Your step count and the workout sessions read for the duplicate check are not stored: they are held in memory only while the app is running and are re-read from Apple Health each time. No Apple Health data is stored in iCloud. It is never used for advertising or marketing, never sold, and never shared with data brokers. It is not shared with any other user unless you explicitly turn on sleep sharing (see Section 6). Where you ask Coach a question, Health-derived energy and weight figures may appear in the summary of your day that accompanies your message — see Section 7.
You can revoke Healthness's access at any time in the iOS Settings → Privacy & Security → Health screen, or from within Healthness. Deleting your account removes the stored sleep, energy, and weight records along with the rest of your data.
Most data is collected when you enter it directly during onboarding, when you log a meal, water, an exercise, a gym set, a fast, or a supplement, when you send a message to Coach, or when you accept a friend invitation. Sleep, measured energy, steps, body weight, and recorded workout sessions are read from Apple Health only after you connect it and grant permission. Push tokens are issued by Apple/Firebase when you grant notification permission. Subscription status is provided by Apple when you make or restore a purchase. Crash reports are sent automatically when the app encounters an unrecoverable error.
We collect your data to:
We do not use your data for advertising, profile selling, or cross-app tracking. We do not present third-party ads in the app. Health and fitness data — including anything read from Apple Health — is never used for advertising or marketing, never sold, and never shared with data brokers.
Healthness lets you connect with friends or family who also use the app. A connection is established only after both users explicitly accept it. Once connected, the other user can see, for the current day:
The following are never shared with friends: your email, password, age, weight, height, individual food entries from manual or barcode logging (only daily totals are shown), historical days other than today, captured-meal text notes you wrote for yourself, your water intake log, your exercise log, your gym workouts and routines, your fasting records, your energy-after-fast ratings, your Coach conversations, and your supplement stack and micronutrient data. Water, exercise, gym, supplement, and micronutrient data are visible only to you, as are your fasting records — a friend sees only that a fast is running, never your history. Sleep is visible to a friend only while you keep sleep sharing switched on.
Sharing stops immediately when either party deletes the friendship, blocks the other user, or deletes their account.
Healthness uses Anthropic PBC's Claude API for the features below. In every case the request travels over a secure HTTPS connection to our Firebase Cloud Functions backend, which forwards it to Anthropic. You can use Healthness without ever opening Coach and without ever photographing a meal; nothing is sent to Anthropic unless you use one of these features.
When you use the "Capture Meal" feature, the photo you take or pick is sent for nutritional estimation. The cooking-method tags and any optional note you provide are sent alongside the photo to improve accuracy.
When you use the "Scan Label" feature to photograph a nutrition or supplement facts panel, the photo is sent the same way to identify the product, classify it as a supplement, food, or drink, and extract its serving size, macronutrients, and micronutrients. Based on that classification, the result is saved either to your supplement stack or to your food list — you can review and change any of it before saving. The label photo itself is not retained after analysis.
You can also ask the app to AI-estimate micronutrients for a food or supplement you've entered manually, using only the name, dose, or macro values you provide — no photo is involved in this case.
When you send a message to Coach, your recent conversation is sent together with a summary of your current day so the reply is grounded in your actual data. That summary can include your display name, age, sex, height and weight, your activity level and fitness goal, your calorie and macronutrient goals and totals, your logging streak, micronutrient coverage and any nutrients that are low or over their limit, water intake, fasting status, the foods you logged today and other notable foods, your supplement stack and what you've taken today, calories burned from exercise, and your calorie totals for the last seven days. It also includes a summary of your last 30 days, so that Coach can answer a question about how a month has gone rather than estimating it from today: how many of those days you logged, your average intake against the calorie goal that was in force on those days and how many days fell at or under it, your smoothed trend weight, how much it changed across the window and the resulting weekly rate, the number of days you trained, the number of gym sessions and your training days per week, and your average nightly sleep. Those are summary figures, not your individual entries — no single meal, weigh-in, workout or night's sleep is sent as a record. Where you have connected Apple Health, the energy, weight and sleep figures in that summary originate from Apple Health.
Coach is a wellness feature, not a medical service: it does not diagnose, treat, or prescribe, and it is not a substitute for a qualified healthcare professional.
Per Anthropic's API terms, photos and text sent for these features are processed only to generate a response and are not retained for training. We do not retain raw images on our backend beyond what is needed to display the meal in your own captured-meals list (stored in Firebase Storage under your user account).
AI estimates are approximations. They may be inaccurate. You can edit any item before saving.
Healthness uses two kinds of notifications:
You may opt in or out of notifications at any time via iOS Settings > Notifications > Healthness.
We use the following processors:
Products found by a barcode lookup are cached in a shared product database so the next person to scan the same item gets an instant result. That cache holds product information only — name, brand, and nutrition — together with the user ID of whoever first scanned it, and is never linked to what you logged or ate.
None of these services receive personal data for advertising or profiling. Your water, exercise, gym, sleep, weight, and fasting data are stored in Firebase and in a local database on your own device (see Section 14); they are never sent to Open Food Facts, USDA, or any other third party, and reach Anthropic only in the day and 30-day summaries that accompany a Coach message you choose to send.
If another user shares content you find inappropriate, you can use the Report option (available from a friend's profile or from the meal photo viewer) to flag it. Reports are stored on our backend and reviewed within 24 hours. If a report is upheld we may remove the offending content and, in serious cases, suspend the reported account. You can also Block any connected user at any time, which immediately ends the friendship and prevents further interaction.
You have full control over your personal data in the app. You can:
To exercise any of these rights you don't have direct access to in the app, contact us at the email below.
Healthness is a fitness and wellness tool, not a medical device. The calorie targets, macronutrient targets, hydration goals, calories-burned estimates, sleep scores and sleep-stage readings, fasting body-stage information, energy-after-fast trends, micronutrient tracking, Coach replies, and AI nutritional analyses provided by the app are approximations intended for general informational purposes. They are not a substitute for professional medical, dietary, or fitness advice. Coach does not diagnose, treat, or prescribe.
Sleep information shown in Healthness is derived from what Apple Health reports and from a score the app computes from it. It is not a clinical sleep assessment and must not be used to diagnose or rule out any sleep disorder.
Fasting in particular carries real risks for some people. Extended fasts (especially beyond twenty-four hours) and any fasting practice may be unsuitable for individuals with diabetes, a history of disordered eating, heart conditions, low blood pressure, kidney disease, those who are pregnant, nursing, or under the age of 18, those taking medication that requires food, or those who are otherwise medically advised not to fast. Body-stage content (catabolic, fat burning, ketosis, autophagy) describes general patterns observed in published research; it is educational, not individualized medical guidance. Supplement information shown in the app (including AI-estimated micronutrient content) is for personal tracking only and is not a recommendation to take any supplement — consult a healthcare provider before starting or changing a supplement regimen. Strength training carries a risk of injury; the weights and repetitions you record in the app are a log of what you chose to do, not a training prescription.
Consult a qualified healthcare provider before making significant changes to your diet, hydration, exercise routine, training load, fasting practice, sleep habits, or supplement intake, particularly if you have a medical condition, are pregnant, or are under the age of 18.
Your data is retained for as long as your account exists. When you delete your account, your profile, foods, daily intakes, captured meals, meal photos, water entries, exercise entries, gym sessions and routines, sleep records, energy and weight figures read from Apple Health, weigh-ins you recorded yourself, fasting records, energy ratings, supplement stack and check-off records, friendships, and personal report records are deleted from our active databases, and the local database described in Section 14 is deleted from your device as part of the same operation. Coach conversations live on your device and are removed when you delete them or uninstall the app. Anonymized aggregated metrics and crash reports may be retained for product-quality purposes. Backups in Firebase's infrastructure may persist for a limited period as part of standard operational redundancy and are then purged on Google's regular schedule.
We are committed to protecting your personal information. All traffic between the app and our backend is encrypted in transit (HTTPS / TLS). Data is encrypted at rest by Firebase. Access to operational systems is limited to authorized personnel. Despite these measures, no internet service can be guaranteed 100% secure; we encourage you to use a strong, unique password and to keep your iOS device secured.
On-device storage. Healthness keeps a local copy of most of your own records on your phone, so the app opens with your history already in front of you instead of fetching it every time. That copy holds your custom foods and saved meals, daily intakes, captured meals, exercises, workout routines, fasts, supplement stack and check-offs, sleep records, measured energy, and your weigh-ins. It is not a separate collection of data: everything in it is data described elsewhere in this policy, held on the device as well as in Firebase, and changes you make are sent on to Firebase so both stay level. Water entries and in-app notifications are not stored this way. The database lives in the app's private storage, is keyed to the account that is signed in, and is removed when you uninstall Healthness or delete your account.
Healthness is not intended for users under the age of 9. We do not knowingly collect personal data from children under 9. If you are a parent or guardian and believe that your child has provided us with personal data, please contact us at swiftuivan@gmail.com, and we will take steps to delete such information.
Healthness is operated using Google Firebase infrastructure. Your data may be stored and processed on servers located in the United States, the European Union, or other regions where Google maintains facilities. By using the app, you consent to the transfer of your data to these locations. We do not sell or share your personal data with third parties beyond the processors listed in Section 9.
We may update this Privacy Policy from time to time as the app evolves. The "Effective Date" at the top of the page reflects the most recent revision. Material changes will be communicated through the app or by email where appropriate. Continued use of the app after a change indicates your acceptance of the revised policy.
