Effective date: June 24, 2026
This Privacy Policy explains how NANOVERSE TECH LTD (“NanoVerse Tech”, “we”, “us”) handles information when you use Cleo. Cleo is intended for adult parents and caregivers. A child should not create or manage an account independently.
Information you provide
Depending on the features you use, Cleo may process an Apple account identifier and, when Apple makes them available, your name and email address; baby and family profile information; sleep, feeding and diaper logs; growth, milestone, vaccine, teething, medication, fever, illness, allergy and solid-food records; memories, notes and family-sharing details; and messages you choose to send to the AI assistant or support team.
Device and Apple services
Core tracking records are stored locally on your device using Apple storage technologies. If you enable HealthKit, notifications, widgets, Live Activities, Watch features or family sharing, Cleo accesses only the data and permissions needed for those features. Optional family sharing may use Apple CloudKit. Health data is not used for advertising.
AI assistant
When you choose to use the AI assistant, your message and a relevant summary of recent baby logs, memories, health information or food-trial information may be sent securely through our Supabase service to an AI service provider to generate a response. Do not use the AI assistant for emergencies. AI responses are informational and are not medical advice, diagnosis or treatment.
Analytics and diagnostics
Cleo uses Firebase Analytics, Crashlytics and Remote Config to understand feature use, diagnose crashes and deliver configuration changes. These services may receive pseudonymous identifiers, device and app information, interaction events, error details and limited event parameters. We do not use baby or health information for targeted advertising and we do not sell personal information.
Purchases
If paid features or subscriptions are offered, purchase and entitlement information is processed by Apple and, where enabled, our subscription service provider. We do not receive your full payment-card details.
How we use information
We use information to provide and secure Cleo, synchronize or share features you request, personalize your experience, answer support requests, operate the AI assistant, process purchases, measure reliability and improve the product, and comply with legal obligations.
Service providers and transfers
We use service providers such as Apple, Google Firebase, Supabase, AI-processing providers and purchase-management providers. They process information on our instructions or under their own platform terms. Information may be processed outside your country with appropriate contractual or legal safeguards.
Retention and deletion
Local records remain on your device until you delete them, delete the relevant profile or remove the app. The in-app deletion flow removes Cleo records associated with the selected profile from local storage and clears local account identifiers. Cloud, analytics, diagnostic, purchase or support records may be retained only as long as needed for the relevant service, security, accounting or legal purpose. To request deletion of service-side records, email info@nanoversetech.co.
Your choices and rights
You can decline optional permissions, disable notifications, avoid the AI and sharing features, sign out, delete records in the app or contact us to exercise applicable access, correction, deletion, restriction, objection or portability rights. You may also withdraw consent where consent is the legal basis.
Security
We use reasonable technical and organizational safeguards. No storage or transmission system is completely secure, so you should protect your device, Apple account and access credentials.
Changes
We may update this policy as Cleo changes. We will update the effective date and provide additional notice when required.
