Privacy Policy
Last updated: July 14, 2026
This Privacy Policy explains how DuoBaby collects, uses and protects your personal data. By using the app, you agree to the practices described here.
DuoBaby is operated by Duosis Soluções LTDA, the data controller under Brazil’s LGPD (Law 13.709/2018) and the GDPR, where applicable.
Who we are
Controller: Duosis Soluções LTDA, company tax ID (CNPJ) 62.626.322/0001-06, at Rua Marianna Bronnemann, 230, Sala 7.
Data Protection Officer (DPO) and privacy contact: contato@duosis.com.br.
Data we collect
Account data: name, email and a password (stored encrypted, never in plain text).
Baby data you enter: name, date of birth and sex.
Routine data you log: feedings (time, duration, volume, side), sleep (time, duration, type) and any notes you add.
Minimal technical data needed to run the service and keep it secure (for example, session identifiers).
We do not collect your location or contacts, and we use no third-party advertising or tracking SDKs.
How we use data
To provide and sync the service across your devices and authorized caregivers.
To authenticate your access and keep your account secure.
To respond to support requests.
To comply with legal obligations and prevent fraud or abuse.
Legal bases
We process your data based on performance of the contract (providing the app you requested), your consent (collected at sign-up) and compliance with legal obligations.
You can withdraw your consent at any time by deleting your account in the app.
Sharing
We do not sell your data. We share it only with providers that operate the service infrastructure, under contract and our instructions: hosting/cloud and email providers (for example, for password recovery).
Subscriptions are processed by the App Store (Apple) and Google Play; we never receive your card details.
Some providers may process data outside Brazil; in those cases we apply appropriate safeguards for international transfers.
Retention and deletion
We keep your data while your account is active.
You can delete your account at any time in Settings › Delete account. This permanently erases your account and associated data (babies, feedings, sleep), except where the law requires retention for a set period.
Your rights
You have the right to access, correct, delete and port your data, as well as to confirm processing and withdraw consent.
Most of these can be exercised directly in the app (edit records, delete account). For the rest, email contato@duosis.com.br.
Children’s data
DuoBaby is intended for parents and guardians. Data about the baby is provided and controlled by you, the responsible adult. The app is not directed to use by children.
Security
We use encryption in transit (HTTPS), hashed passwords and local on-device storage. No system is 100% secure, but we work continuously to protect your data.
Changes to this policy
We may update this policy from time to time. Material changes will be announced in the app or by email. The last-updated date appears at the top of this page.
