Privacy Policy

1. Who we are

Nutribyte is an app for iPhone and Android, together with this website, operated by Sarvon Infotech ("we", "us"). We are responsible for the personal information described in this policy.

For any question about your privacy, or to make a request, email codewithkrish061@gmail.com.

2. What we collect

What we hold depends on how you use Nutribyte. Some of it you give us directly, and some is created as you use the app.

Nutribyte does not collect your precise location, contacts or photos, other than screenshots you choose to attach to a bug report and meal photos you choose to scan (which we don't keep, see section 5). It reads nothing from Apple Health or Health Connect unless you connect it. Nutribyte Pro is paid for through Apple or Google, and we never see your card details.

3. How we use it

• To run Nutribyte for you: your account, plan and diary, and keeping them in step across your devices. We need this to provide the app you've asked for.
• To set your targets and keep them safe: calories, macros, water and steps, and the safety rules described in section 4. For health information we rely on your consent, which you give when you answer those questions.
• To find foods and estimate nutrition, as described in section 5.
• For your Shiba: streaks, stickers, letters and outfits.
• To help you when you contact us.
• To keep Nutribyte secure: checking sign-ins with Apple and Google, limiting repeated requests, and preventing abuse. This is in our legitimate interest and yours.
• To improve the app, using usage and crash data. This is in our legitimate interest.
• To meet legal obligations, where the law requires us to keep or share information.

We don't use your information for advertising, we don't sell it, and we don't use it to make decisions about you such as credit, insurance or employment.

4. Health information

Your weight, height, goal weight, food allergies, pregnancy or breastfeeding status and any health conditions you share are health information, and we treat them with extra care.

• We use them only to set your targets and safety rules, to show your progress and to support you. For example, Nutribyte never plans a calorie deficit during pregnancy or breastfeeding.
• The questions about pregnancy and health conditions are optional. You can skip them, or change or remove your answers in your profile at any time.
• Health information is never sent to our analytics provider and is never used for advertising.

Apple Health and Health Connect

You can connect Nutribyte to Apple Health on iPhone or Health Connect on Android, during setup or later in your profile. Watches, rings and apps that save to those (such as Apple Watch, WHOOP, Garmin, Oura, Fitbit, Samsung Health and Strava) then reach Nutribyte through them. Nutribyte doesn't connect to those companies directly.

• It's your choice. Nothing is read until you connect, and your phone asks you which kinds of data to allow. You can change that at any time in the Health app (Apple) or in Health Connect (Android).
• What we read: steps, active energy burned, workouts, sleep, water other apps logged, weigh-ins and body fat, and, only if you turn on "Meals from other apps" in your profile, meals other apps logged. We show them in your diary and progress, count them towards your activity and water goals, calories and stickers, and use a weigh-in for your progress only when you haven't entered one yourself that day. You can remove any imported meal or workout from your diary.
• What we save there, if you allow it: the meals (calories, protein, carbs, fat, fibre, and sugar, sodium and cholesterol when known), water, workouts and weigh-ins you log in Nutribyte, and the height in your plan, so they appear with the rest of your health data. Once saved there, they're also covered by Apple's or Google's own terms and privacy policy.
• Only for your health and fitness features. We never use this data for advertising, marketing or data mining, never sell it, and never share it with anyone for those purposes. It never goes to our analytics provider, and we never store it in iCloud.
• Nutribyte's use of information received from Health Connect follows the Health Connect Permissions policy, including its Limited Use requirements.
• Disconnecting in your profile stops reading and removes what we imported from our servers: steps, energy, workouts, sleep, body fat, and other apps' water and meals. Imported weigh-ins stay in your history until you delete them or your account.

5. Food search and estimates

Nutribyte has its own list of more than a thousand foods. When you search for something that isn't on it, we use AI providers to help:

• The words you typed are sent to Groq to suggest matching foods.
• When you pick a suggestion, its name is sent to OpenAI (or, when OpenAI can't answer, to Groq or Google (Gemini)) to estimate its nutrition for a typical portion.

We send only that text. We never send your name, email or any other account details, so please don't type personal information into the search box. Answers are saved without any link to you, so a repeated search is instant. A food you log from an estimate is added to our shared food list (just its name and nutrition) so other people can find it too.

Meal photos and barcodes

• Meal photos (Nutribyte Pro): when you take or choose a photo of your meal to scan, it is sent to Google (Gemini) or Groq to recognise the foods and estimate their amounts and nutrition. We don't store the photo on our servers; we keep only the answer (the foods it found), without any link to you, so the same photo isn't sent twice. Point the camera at your food, not at people or documents.
• Barcodes: when you scan a packaged food, its barcode number is sent to Open Food Facts, a free, open database of food products, to find the product's name and nutrition. Products found there are added to our shared food list. If you add a product yourself, its barcode is saved with your food so your next scan finds it.
• The camera is used only while the scanner is open, and only after you allow it.

Estimates can be wrong. Check them, and adjust them before you log.

6. Who we share it with

We share information only with the providers below, and only what each one needs to do its job for us. They may use it only to provide their service to us.

We may also disclose information if the law requires it, or to protect the rights, safety and security of our users or others. If Nutribyte is ever sold or merged, your information would move to the new owner under this policy, and we would tell you first.

7. How long we keep it

Copies in our hosting provider's backups are overwritten on its regular backup cycle.

8. Your choices and rights

• See and correct your information. Most of it can be changed in your profile in the app. For anything else, email us.
• Delete your account. In the app, or by email. See Delete your account.
• Get a copy of your information in a common, machine-readable format, by emailing us.
• Withdraw consent for health information by removing your answers in your profile, or by deleting your account. To stop Apple Health or Health Connect, disconnect it in your profile, or turn off Nutribyte's access in the Health app or Health Connect.
• Object to or restrict how we use your information, by emailing us.

Depending on where you live, you may have further rights. In the EU and UK, you can also complain to your local data protection authority. In California, note that we do not sell or share personal information. In India, you can nominate someone to exercise your rights on your behalf, and raise grievances with us at the email below.

We reply to requests within 30 days, and we may ask you to confirm it's really you first.

9. Children and teenagers

Nutribyte is for people aged 13 and over. If you're under 18, please use it with the permission of a parent or guardian. For anyone under 18, Nutribyte never plans a calorie deficit.

If we learn that we hold information from a child under 13, we will delete it. Parents and guardians can contact us at codewithkrish061@gmail.com.

10. Security

• All traffic between the app and our servers is encrypted (HTTPS).
• Every sign-in is checked against Apple's or Google's published keys.
• We store the tokens that keep you signed in only as one-way hashes, and we keep Sign in with Apple tokens encrypted.
• Access to our servers and data is limited to the people who need it to run Nutribyte.

On your phone, your session is kept in the app's private storage, where your Home Screen widgets can read it too. No system is perfectly secure. If you think you've found a security problem, please email us.

11. Where data is processed

Our servers are run by Hostinger. Google, Groq and Open Food Facts may process data in the United States and other countries. When your information leaves your country, we rely on providers that commit to protecting it, including through standard contractual clauses where the law requires them.

12. Changes to this policy

If we change this policy, we'll update the date at the top of this page. If a change matters, for example a new type of data or a new provider, we'll also tell you in the app before it takes effect.
