Privacy Policy

Introduction

Welcome to BillWink. We value your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, and safeguard your information when you use our application.

2.1 Personal Information

When you create an account, we collect the following to identify and personalise your experience:

• Name

• Profile picture (optional)

2.2 User Data

Data you create inside the app as you use BillWink's core features:

2.3 Device Information

Basic technical data that helps us keep the app stable and performant:

How We Use Your Information

Your information is used solely to operate and improve BillWink. We use your data to:

• Provide and maintain core app functionality
• Sync your data seamlessly across your devices
• Calculate shared expenses and real-time balances
• Improve app performance and overall user experience
• Provide timely and effective customer support

Data Sharing

There are limited cases where your data may be shared:

• Expense and balance data is visible to other members within your shared groups
• Shared with trusted infrastructure services such as Firebase, strictly to power the app
• Disclosed to authorities only if required by law

Data Storage & Security

Your data is stored securely using industry-standard cloud infrastructure. We implement reasonable technical and organisational safeguards to protect your personal information from unauthorised access, loss, or disclosure.

While we work hard to protect your data, no system is completely secure. We encourage you to use a strong, unique password and keep your account credentials private.

Data Retention

We retain your personal data for as long as your account remains active and in use. You may request permanent deletion of your account and associated data at any time — see Section 10 for details on account deletion.

Your Rights

You have full control over your personal data. Specifically, you have the right to:

Permissions

BillWink requests the following device permissions. All optional permissions are only used for the stated purpose:

• Internet — required for syncing your data and connecting to cloud storage
• Camera (optional) — used only for QR code scanning to add friends quickly
• Storage (optional) — used only when setting a profile image from your device gallery

Children's Privacy

BillWink is not intended for children under the age of 13. We do not knowingly collect, store, or process personal data from children under 13. If we become aware that we have inadvertently collected personal information from a child under 13, we will take prompt steps to delete it.

If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately at hello@billwink.com.

Account Deletion

When you choose to delete your BillWink account, your personal information — including your name, email address, and profile details — is permanently and irreversibly removed from our systems.

However, expense records that form part of shared groups may be retained in an anonymized form (shown as "Deleted User") to maintain data consistency and accuracy for the other members of those groups.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make significant changes, we will update the effective date at the top of this page and, where appropriate, notify you within the app.

We encourage you to review this page periodically to stay informed about how we protect your data.
