Privacy Policy of NutriConvo AI

Overview

NutriConvo AI is a voice calorie tracker and AI diet assistant by Useful First. The product uses your account, food logs, nutrition profile, goals, voice-session input, and billing state only to provide and operate NutriConvo AI.

Information We Collect

When you sign in, log meals, manage your profile, or manage access, Useful First receives information needed to provide the product:

• Email address, name, and Firebase identity subject from Apple or Google sign-in.
• Profile, goal, onboarding, target, and progress information you enter.
• Meal descriptions, food logs, nutrition estimates, notes, and corrections.
• Voice commands, transcripts, voice-session metadata, and generated nutrition summaries.
• Subscription, trial, entitlement, billing status, checkout, and payment-provider identifiers.
• Device, request, error, and operational logs needed to secure and operate the service.

Voice And AI Processing

Voice-session input and meal descriptions may be processed by speech, language-model, and food-data providers so NutriConvo AI can understand your request and convert it into food logs, estimates, and summaries. The product sends only the information needed to process your request and return the requested result.

NutriConvo AI keeps available final user and assistant transcript turns for 30 days after each voice or text session. When you choose voice mode, it also keeps your microphone audio for 30 days. Text mode does not capture audio. These fixed periods also apply to copies of this voice-session data.

The voice provider's room-level capture setup may briefly receive other audio tracks before their source is identified. Only the signed-in user's microphone track is eligible for retention; assistant or unexpected tracks are quarantined and erased after they are identified.

Useful First does not use food logs, health-related profile data, voice commands, transcripts, or generated nutrition summaries for advertising.

How We Use Information

• To create and manage your NutriConvo AI account.
• To interpret voice or text meal descriptions and create food logs.
• To calculate and show targets, summaries, progress, and entitlement state.
• To support web checkout, mobile store purchases, refunds, access management, and account support.
• To detect abuse, debug failures, maintain security, and operate the service.

Useful First does not sell user data.

Sharing

Useful First shares data only with service providers needed to operate the product:

• Firebase, Apple, and Google for identity and authentication.
• Stripe, the App Store, and Google Play for checkout, subscription processing, refunds, and billing records.
• Speech, language-model, food-data, hosting, database, and infrastructure providers used to run NutriConvo AI.

Useful First may also disclose information if required by law or to protect the security and integrity of the product.

Security And Retention

Account, food log, billing, and voice-session requests are sent over HTTPS. The backend verifies Firebase identity tokens and maps them to an internal NutriConvo AI account.

While you maintain an account, Useful First keeps account, profile, food log, billing reference, support, and operational information for as long as needed to provide access, maintain billing records, prevent abuse, resolve support requests, and comply with legal obligations. Voice-session transcripts and voice-mode microphone audio follow the fixed 30-day period described above. Account-deletion requests follow the process described below.

Account Deletion

When an account-deletion request is accepted, access to NutriConvo AI ends immediately. Your live product data becomes eligible for permanent deletion from the active service 30 days after the request. Deletion from the active service proceeds only after Useful First has also verified that live voice-session data associated with the account has been erased from the active service, so completion may take longer than 30 days if that verification is still pending. This policy does not specify a backup-erasure timeframe.

When permanent deletion from the active service proceeds, the underlying account record is anonymized. Useful First may retain deletion audit records and limited records needed for billing, fraud prevention, security, or legal compliance. Retained payment-provider event records are detached from the anonymized account.

Raw Apple and Google sign-in links are removed. Useful First retains a keyed, one-way identity digest—a protected fingerprint instead of the original provider identifier—only to prevent a deleted identity from creating a replacement account or receiving introductory access again. It is not used to sign in.

If the account used Sign in with Apple, Useful First may also retain a yes-or-no record of whether Apple authorization revocation was required for the deletion. That record does not track whether revocation was completed and does not contain the Apple identity subject, which is the Apple account identifier used for sign-in.

While deletion is being finalized, the app stores a temporary checkpoint on your device containing the sign-in provider and internal account ID, plus the deletion receipt when one is available. This allows cleanup to resume if it is interrupted. The checkpoint is cleared after cleanup finishes.

Deleting your NutriConvo AI account does not cancel an App Store subscription. App Store subscriptions must be canceled separately through your Apple Account.

Cookie Policy

NutriConvo AI web sign-in uses Firebase Auth in the browser. Payment processing is handled by Stripe, which may set its own cookies or use similar technologies during checkout. Apple, Google, and Firebase may also use cookies or local browser storage when you choose account sign-in. Those services process data under their own privacy policies.

GDPR Compliance

If you are located in the European Economic Area, the United Kingdom, or another region with similar data protection laws, you may have rights to access, correct, delete, restrict, or object to certain processing of your personal data. You may also have the right to request a copy of your personal data.

Useful First processes account, profile, food log, billing, and usage data to provide the service, manage subscriptions, prevent abuse, respond to support requests, and comply with legal obligations. To make a privacy request, contact Useful First at support-nutriconvo@usefulfirst.com.
