Privacy Policy

Who we are

DietAIcian is an app that builds meal plans and helps you track what you eat. It is made and run by LUMINOVIX TECHNOLOGIES, a sole proprietorship registered in Maharashtra, India ("we", "us"). We are responsible for the personal data described here.

Questions or requests about your data: support@dietaician.com

What we collect

• Your account: when you sign in with Google, we receive your name, email address and a Google account ID. When you sign up with email instead, you give us your name, email address and a password. Your password is stored only by Google's Firebase Authentication, in a form that cannot be read back; we never see it. We send you an email to confirm your address, and the AI features start once you have confirmed it.
• Your profile: what you enter in setup and Settings - age, sex, height, weight, goals, activity level, meal and snack times, diet type, food likes and dislikes, cooking skill, grocery budget and currency.
• Health information: food allergies, intolerances, medical conditions and any health notes you choose to enter. We use it only to keep your meal plans safe for you.
• Food logs: the meals you log, their calories and nutrients, and meals you mark as eaten or skipped.
• Meal photos: a photo you take to log a meal is sent for analysis and is not stored on our servers afterwards.
• Location (optional): only if you tap to detect it during setup. The app reads your phone's approximate location once to find your country and state or region. We store the country and region, not your coordinates. You can type your location instead.
• Purchases: whether you subscribe, and when your subscription renews or ends. Google Play handles the payment; we never see your card or bank details.
• Usage records: how many AI requests you make each day and when your free trial started, so we can apply the daily limits and the trial. We also record what our AI provider charges for each request, per day, so we can keep costs under control; the per-person totals use a one-way code, not your account ID.
• Crash and error reports: if the app or our server hits an error, a report of the error and where it happened, with your device model, Android version and app version. It does not include your name, email, account ID or health information.
• Health Connect (optional, Android): if you connect it, your steps, calories burned, workouts and weight. See Health Connect below.
• Circles (optional): if you create or join a circle, its name, who is in it, and the name shown for you there. See Circles below.
• Reports you send: if you report AI content in the app, what you wrote and which meal or insight it was about; if you report a name in a circle, which name and the reason you chose.
• Feedback you send (optional): what you write and the type you choose; screenshots, only if you add them (they show whatever was on your screen); technical details, only if you tick the box: your phone model, Android version, app version and the app's recent error messages (with any email addresses removed); and your email address, only if you ask us to reply.

We do not use advertising, analytics or tracking tools, and we do not track your location in the background.

How we use it

• To create your meal plans, recipes and meal swaps, estimate the nutrition of meals you log, and show your progress.
• To check plans against your allergies, diet and health conditions.
• If you are in a circle, to show its members your streak, scores and whether you have logged today.
• To run your free trial and subscription, and to apply daily limits that keep the service affordable and prevent abuse.
• To answer you when you write to us, to look into the AI content you report, and to confirm account deletion requests.
• To read and act on feedback you send, reply when you ask us to, and add the free Pro days described in our Terms of Service.

We do not sell your data, and we do not share it for advertising. You enter health information by choice. When you finish setup, the app asks you to agree to us using it for the purposes above; you can remove it at any time in Settings, or delete your account.

Who else handles your data

We use these service providers to run DietAIcian. Each receives only what it needs:

• Google (Firebase Authentication, Cloud Firestore, Cloud Storage, Google Sign-In, Google Play, Google Workspace email): sign-in, storing your profile, logs and feedback (screenshots in Cloud Storage), payments, and our email.
• Vercel: hosts our website and the server the app talks to.
• Sentry: receives the crash and error reports described above, to help us fix problems. It may process them in the United States.
• Resend: sends our emails, such as account deletion confirmations, and reports of AI content and feedback (with any screenshots) to our support inbox. It receives the email address a message goes to and the message itself.
• OpenAI: our server sends it your profile (including health information and your latest weight) to write meal plans, recipes and swaps; your daily calorie, protein, carb and fat totals for the past week to write your weekly review; and your meal photos and descriptions to estimate nutrition. It does not receive your name or email address. Under OpenAI's terms for business use, this data is not used to train its models; OpenAI may keep it for a limited time to monitor for abuse.
• RevenueCat: manages subscriptions. It receives your purchase records, free Pro days we add as feedback rewards, and an account ID, not your name or health data.
• Open Food Facts: receives the barcode number when you scan a product.
• Your phone's location service, and OpenStreetMap: when you detect your location, your phone turns it into a place name (on Android this is Google's service). If that fails, an approximate position (to about 10 km) is sent to OpenStreetMap's Nominatim service.

Health Connect

On Android you can connect DietAIcian to Health Connect, the phone's shared health store that apps such as Samsung Health, Google Fit and Fitbit sync into. It is optional, and you choose what to share on Health Connect's own permission screen.

• What we read: steps, active calories burned, total calories burned, exercise sessions (workouts) and weight. We never write, change or delete anything in Health Connect.
• Steps, calories burned and workouts are read on your phone to show your activity on the Today screen and, only if you switch it on, to raise that day's calorie target by half of the calories your workouts burned (at most 500 kcal). They are not sent to our servers or to anyone else, and are not stored by us.
• Weight readings are added to the weight history in your DietAIcian profile, as a weight you type in would be. Your latest weight is part of the profile used to create meal plans (see "Who else handles your data"), and it is deleted with your account.
• We do not use Health Connect data for advertising, sell it, or use it for anything other than the features above. People at DietAIcian do not read it.
• To stop: turn Health Connect off in DietAIcian (Settings > App Settings), or remove DietAIcian's access in Health Connect. Deleting your account also withdraws the access.

Circles

A circle is a small private group - a family or friends - that you create or join with a 6-character code. It is optional, and the app asks you to agree before you create or join one.

• What the others in your circle see: your name, your streak (days in a row with food logged), whether you have logged food today, and your weekly and monthly scores (the share of days you logged food and finished within 10% of your calorie target). They are worked out on our server from your food log.
• What they never see: your weight, your meals, your calories, your allergies or health conditions, your email or your account ID.
• Reports and removal: anyone in a circle can report the circle's name or a member's name; the report goes to our support inbox. The person who made the circle can remove members.
• To stop: leave the circle at any time, or delete your account; either removes you and what the circle showed about you.

Where it is stored, and how it is protected

Your data is stored on Google Cloud servers and processed by the providers above, which may be outside your country, including in the United States. These providers are bound by their own data protection terms.

Everything travels encrypted (HTTPS). Database rules let only you read your own profile and logs; other users cannot see them. Only our server can change your subscription and usage records.

How long we keep it

• Your account data is kept until you delete your account. Deleting it removes your profile, food history, meal plans, usage records, reports and feedback you sent (with their screenshots), friend circle membership and sign-in account straight away.
• Each report and feedback is also emailed to our support inbox. Those emails stay there until you ask us to delete them at support@dietaician.com.
• One record is kept after deletion: a one-way scrambled code made from your email address, with the date your free trial started, so a new account with the same email does not get a second free trial. It cannot be turned back into your email address and holds nothing else.
• Web deletion requests: once completed, we keep only the fact that a request was completed, and the reason if you gave one - not your email address.
• Service providers may keep technical records, such as server logs, for a short time under their own terms.

Your rights

• See and correct your profile and health information in the app, under Settings.
• Get a copy of your data: email us from your account's email address.
• Delete your account: in the app, Settings > Account & Privacy > Delete Account & Wipe Data. Without the app, use our account deletion page.
• Stop location access at any time in your phone's settings.

We answer requests within 30 days. Depending on where you live (for example the EU, the UK or India), you may also have the right to object to or restrict how we use your data, and to complain to your data protection authority.

Age

DietAIcian is for adults aged 18 and over. We do not knowingly collect data from anyone younger. If you believe someone under 18 is using the app, write to us and we will delete the account.

Changes to this policy

When this policy changes, we update the date at the top. If a change affects how your data is used, we will tell you in the app before it applies.

Medical disclaimer

DietAIcian's AI-generated meal recommendations are for educational and self-management purposes only. They are not a substitute for professional medical care, diagnosis or nutrition therapy. Please consult a qualified healthcare professional or registered dietitian before starting a new diet, especially if you have a health condition.
