Privacy Policy

Effective and last updated: September 14, 2026

This Privacy Policy explains how SINEA ("we", "us", or "our") handles information when you use the Family Plan application, website, and related services (collectively, the "Service").

1. Information we collect

Depending on the features you use, we may collect:

• Account information: your Google account identifier and, when provided by Google, your verified email address, display name, and profile image; profile details you add, such as a name, avatar, birthday, backup email address, and safety-lock preferences.
• Family Plan content: family profiles and relationships, goals, check-in records, rewards, balances, reminders, backup preferences, and other content you choose to create.
• Purchase and membership information: Google Play product and base-plan identifiers, order references, subscription and acknowledgement status, purchase and expiry times, region, obfuscated account or family identifiers, and an encrypted purchase token used to verify and maintain your entitlement. We do not receive your complete payment-card details.
• Technical and usage information: app version, device description, login dates and timestamps, IP address and browser information used in web verification or support flows, error logs, and security-related records.
• Support communications: information you include when contacting us.

2. How we use information

• Provide, synchronize, maintain, and improve the Service.
• Authenticate users, manage families and memberships, and protect accounts.
• Process transactions and provide purchased features.
• Respond to support, privacy, and account-deletion requests.
• Detect abuse, prevent fraud, troubleshoot errors, and comply with legal obligations.

3. How information is shared

We do not sell personal information or share it for third-party advertising. We disclose the minimum information necessary to service providers that help us operate the Service, including Google for sign-in and Google Play Billing, infrastructure and database providers, and email delivery providers. These providers process information on our behalf or under their own terms for the requested service. We may also disclose information when required by law or when necessary to protect users, the Service, or our legal rights.

Website analytics: We use Cloudflare Web Analytics on this website to measure aggregate page visits and website performance. Cloudflare states that Web Analytics does not use cookies and does not collect or use visitors' personal data.

4. Family and shared content

Information placed in a family workspace may be visible to other members of that family. Account deletion removes the deleting account and account-scoped content. Records created for another family member may remain for that member, but the deleted account's identity is removed from those records. If another account holder remains in a family, the family owner must transfer ownership before deleting the owner's account. If no other account holder remains, deleting the owner account also deletes the family workspace and its profiles and content.

5. Data retention and deletion

We retain account information while your account is active and as needed to provide the Service. You may permanently delete your account from the app or through our Delete Account page. Once completed, the account record, Google connection, login records, backup-email tasks, and account-scoped profiles, goals, check-ins, rewards, balances, and related content are deleted. Identifying links on records retained for another family member are removed.

Deleting Family Plan does not cancel a Google Play subscription; cancel it separately in Google Play. Limited purchase, transaction, fraud-prevention, security, or legal records may be retained only for the period required by applicable tax, accounting, payment, security, or other legal obligations. Retained records are separated from the deleted account, restricted from ordinary product use, and deleted or anonymized when the applicable retention obligation ends.

Referral records: if you open an invitation, the app stores its code locally and may retrieve it from Google Play Install Referrer. On your first successful Google registration, we record the inviter, registered account identifier, invitation channel, and reward status. To enforce one registration reward per Google account and annual invitation limits, we retain a minimal Google account identifier and referral/reward ledger after account deletion for as long as this referral program operates. These retained records do not include your family content and are not used to restore a deleted account.

6. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information, including authenticated access, encrypted network transmission, encryption of Google Play purchase tokens at rest, and redaction of credentials from application logs. Device biometric templates are processed by the operating system and are not sent to us; the Service stores only your biometric-unlock preference and safety-lock configuration. No storage or transmission method can be guaranteed to be completely secure.

7. International processing

Your information may be processed in locations where we or our service providers operate. Where required, we use appropriate safeguards for cross-border transfers.

8. Children's privacy

Family Plan accounts are intended to be managed by a parent, guardian, or other authorized adult. Family profiles created within an adult-managed account are not independent login accounts. If you believe a child has provided personal information without appropriate authorization, contact us so we can investigate and delete it where required.

9. Your choices and rights

Depending on your location, you may have rights to access, correct, export, restrict, object to, or delete personal information. Contact us to submit a request. We may need to verify your identity before completing it.

10. Changes to this policy

We may update this policy to reflect changes to the Service, law, or our practices. We will update the effective date and provide additional notice where required.
