Effective September 12, 2026 · Nuta iOS 1.2
Nuta is provided by Yuri Istomin. This policy explains the app’s local processing and the data used by its account, cloud and analytics services. Contact yuri.istom@gmail.com with privacy questions.
Local health and food features
With your permission, Nuta reads Apple Health data such as sleep, heart rate, heart-rate variability, activity and workouts. Running suggestions are computed on your device. Meal records, photographs, weight records and daily context are stored locally for the app’s features. Cycle context is optional. Local processing alone does not send these records to us.
Accounts
Supabase provides authentication and account storage. When you sign in, we process your account identifier, email address and any name you provide. Apple sign-in may supply a private relay email. Passwords and sign-in tokens are handled by the authentication service; never include them in chat or support messages.
Optional cloud AI coach
Before you share with the coach, Nuta asks for permission. Your messages and relevant summaries of health readings, sleep, activity, meals, weight and check-ins can be sent through Supabase to OpenAI to produce responses. The coach can request relevant history through app tools; tool results are also sent to the cloud. This can include sensitive health information and anything you type into the conversation. Your running suggestion remains computed locally.
Chat messages, context and tool results are stored in your Supabase-backed account to provide conversation history. OpenAI processes the supplied conversation to generate responses under its API service policies. We request that completions are not stored by OpenAI. API data is not used for model training by default; abuse-monitoring logs may still be retained for up to 30 days, or longer where required by law or to protect against harm. Permission lasts while the chat is open. Stop sharing in the chat toolbar to stop further coach requests, or decline and continue using local features. Stopping sharing does not delete information already sent. Delete your account in Nuta Settings to remove the account and its associated cloud data.
Purchases and existing data
Smart Menu is unavailable in Nuta 1.2, and this version does not send menu-generation requests. Updating does not delete existing menu data from earlier versions; you can contact us with a data request. Apple processes App Store purchases and subscription payments. Nuta uses purchase status to enable paid features; we do not receive your payment-card details.
Usage analytics
Nuta uses Amplitude to understand feature usage and improve reliability. Events can include a persistent app user or device identifier, app and device information, approximate location derived from an IP address, purchase outcomes, and interactions such as screens opened or authentication outcomes. These analytics are separate from the coach’s health context. We do not use HealthKit data for advertising.
Service providers and retention
Data is processed by the service providers described above to operate the requested features. Providers may process data in countries other than where you live. Cloud chat history remains associated with your account until you delete the account or we remove it through a verified support request. Account deletion removes the Supabase authentication record and app-controlled cloud chat, menu, preference and entitlement records. Nuta also clears its local app records and preferences from that device. Health data remains in Apple Health, and copies in device or iCloud backups remain subject to Apple’s backup retention.
Security and diagnostic logs may remain for up to 30 days, and encrypted provider backups may remain until their normal rotation, typically within 30 days. We may retain specific records longer where required by law. We do not use retained records to continue providing services to a deleted account. Information already processed by Apple, OpenAI or Amplitude remains subject to each provider’s retention policy; deleting the Nuta account does not instantly erase those providers’ security logs, billing records or previously processed analytics and AI requests.
Your choices
- Change Health and photo permissions in Apple’s settings.
- Decline cloud AI sharing, or stop it from the chat toolbar.
- Edit or delete local records using the app’s controls.
- Permanently delete your account and its associated cloud data in Nuta Settings, or request access and correction through our support contact.
- Manage notifications in Nuta and iOS Settings.
Deleting your Nuta account does not cancel an App Store subscription. Apple continues billing until you cancel in your Apple Account subscription settings. We may need to verify account ownership before handling a support request. Removing the app clears its local data but does not itself remove server-side account or chat records.
Children and medical use
Nuta is intended for people aged 13 and older. It is a wellness and fitness app, not a medical device. If you believe a child has provided personal information, please contact us.
Updates
We update this page when our data practices change and revise the effective date. Material changes to optional data sharing will be explained in the app where applicable.
