About this policy
Nüwa is a nutrition app with an artificial intelligence coach, Nü. She plans your day, estimates calories and nutrients from what you tell her by text, voice or photo, and suggests adjustments. We process the data needed to provide, protect and improve the service, and to measure our own marketing campaigns.
We do not sell your personal data. We do not share what you eat, your photos, your voice or your conversations with Nü with advertising networks.
Data we collect
Account and identity
Your name, email address and password (stored hashed). You can start without an email: in that case we create a guest account identified only by an internal code. If you sign in with Google or Apple, we receive your email address from them (with Apple, this may be a private relay address) and an identifier for your account with that service. We never receive your Google or Apple password or access to anything else in those accounts.
Profile and goals
Age, sex, weight, height, activity level, goal, dietary restrictions, wake and sleep times, and water, calorie and protein targets.
Food, hydration and progress
Planned and logged meals, nutritional estimates, water intake, weight entries and the weekly reviews built from them.
Conversations with Nü
The messages you exchange with the coach and the plans you mention to her, so she can answer and remember the context.
Photos and voice you send
Pictures of your plate and voice recordings you choose to send, only to estimate the meal. They are optional: you can always type instead.
Approximate location
Only if you allow it and ask for restaurant suggestions, we use the device location at that moment to find places nearby. We do not keep a location history.
Subscription
Plan, trial, renewal dates and subscription status. Payment details stay with Apple or Google; we never receive them.
App usage and device
Usage events (for example, finishing onboarding or logging a first meal), device and advertising identifiers, model, operating system, app version, language, time zone, IP address and security logs.
How we use your data
- Create, authenticate and protect your account.
- Work out your targets and plan your day.
- Estimate calories and nutrients from text, voice or photos.
- Generate Nü's suggestions, weekly reviews and replies.
- Send reminders and notifications you can turn off in settings.
- Manage your trial and subscription.
- Understand how the app is used and measure how well our marketing campaigns work.
- Provide support, prevent abuse and comply with legal obligations.
We process data to provide the service you signed up for, with your consent (for example for the camera, microphone, location and notifications), to comply with legal obligations, or based on legitimate interests compatible with your rights. Health and wellness data receives additional protection under Brazil's LGPD and other applicable laws.
Advertising and measurement
We promote Nüwa with ads on Meta (Facebook and Instagram). To learn which ads lead to installs and subscriptions, the app sends Meta events such as install, app open, finishing onboarding, creating an account and logging a first meal, together with device identifiers. RevenueCat sends Meta the trial-start and subscription events. These events do not include what you eat, your photos, your voice, your conversations or your health data.
On iPhone, we do not ask for tracking permission (App Tracking Transparency) and Apple's advertising identifier is not accessed; measurement uses Apple's and Meta's aggregated, privacy-preserving mechanisms. On Android, you can reset or delete your advertising ID in your device settings.
How we handle photos and voice
Your photo or recording is transmitted temporarily for automated analysis. Nüwa does not store the image or the audio in its database, create a gallery, or link them to your account history. Once the response needed to estimate the meal is produced, they are discarded. What stays on record is the meal, as text.
The camera, gallery and microphone are accessed only after an action from you and with device permission. If you deny permission, you can still log meals by typing.
Retention and deletion
Account, profile, meal, conversation and progress data is kept while your account is active. Guest accounts, created without an email, are deleted automatically 30 days after they are created, unless you save the account before then, with an email, Google or Apple.
When you delete your account, we erase the account and associated data from active systems, including the notification profile, except for information whose retention is required by law, security, fraud prevention or the protection of rights. If you signed in with Apple, we also revoke Nüwa's access to your Apple account. Residual data in backups follows those systems' secure retention cycle. Deleting your account does not cancel your subscription: that is managed and cancelled with Apple or Google.
Delete your account
In the app: Settings → Delete my account.
Without the app, email privacy@nuwafit.com from your registered address with the subject “Delete my Nüwa account.” We may verify your identity to protect your account.
How to delete your accountYour rights
Depending on your location, you may request confirmation, access, correction, portability, information about sharing, anonymization, blocking or deletion, object to processing, and withdraw consent. Camera, microphone, location and notification permissions can be revoked at any time in your device settings. To exercise a right, email privacy@nuwafit.com. We may verify your identity before fulfilling the request.
Nüwa is not intended for children under 13. We use reasonable security measures, but no system is completely immune to risk. We may update this Policy when the product, providers or laws change; the date above identifies the current version.
