Brush Quest

Privacy Policy

Effective Date: April 1, 2026

Brush Quest is a toothbrushing game for children ages 4–8, built by a dad for his own kids and shared with other families. We designed it to be the kind of app we'd want on our own children's devices — safe, simple, and private by default.

This policy explains what data we handle, how we protect it, and your rights as a parent. It complies with the Children's Online Privacy Protection Act (COPPA), including the 2025 amendments, the California Consumer Privacy Act (CCPA/CPRA), and Google Play's Families Policy.

1. What We Collect

Game Progress (stored on your device)

Brush Quest saves gameplay data locally using your device's built-in storage (SharedPreferences) so your child's progress is kept between sessions:

• Brush count, brushing history (dates only), and streak data
• Stars earned, unlocked heroes and weapons
• Settings preferences (timer duration, sound, camera toggle)

This data never leaves the device unless a parent opts in to cloud backup.

Cloud Backup (optional, parent-controlled)

A parent may choose to sign in with Google to back up game progress to the cloud. This is entirely optional — the app works fully without it. Cloud backup is behind a parental gate (math verification) and requires the parent to tap "I Consent" before any data leaves the device.

When cloud backup is enabled, we store:

• Parent's email address — to identify the cloud save account
• Parent's display name — shown in Settings so you know which account is connected
• Firebase UID — a unique identifier assigned by Google to secure your cloud save
• Game progress data — the same brushing history, stars, and unlocks stored locally

No profile photos, contacts, or other Google account data is accessed. The child's name and age are never collected. Cloud data is stored in Google Cloud Firestore (US region) under strict security rules that ensure each user can only access their own data.

Camera (optional, off by default)

Brush Quest can use the front camera to detect brushing motion during gameplay. This feature is disabled by default and must be enabled by a parent in Settings (behind the parental gate).

• Camera frames are processed entirely on the device in real time
• Each frame is reduced to a small pixel grid and produces a single motion score — a number, not an image
• No facial recognition, no biometrics, no identification of any kind
• No images or video are ever stored, recorded, uploaded, or sent anywhere
• The camera is only active during the brushing session and stops immediately when brushing ends

Crash Reports (automatic, anonymous)

The app includes Firebase Crashlytics, which automatically sends anonymous crash reports when the app encounters an error. These reports contain:

• Device model and operating system version
• Technical error details (stack traces)
• App version number

Crash reports contain no personal information — no names, no email addresses, no gameplay data. They help us find and fix bugs.

Anonymous Usage Analytics (automatic)

The app uses Firebase Analytics, configured for child-directed treatment under COPPA, to understand how the app is used in aggregate. This helps us improve the brushing experience for all families.

• Events like brush session completion, onboarding progress, and feature usage
• No advertising IDs are collected (explicitly disabled in code)
• No ad personalization, remarketing, or profiling
• Data is anonymous and aggregated — it cannot identify any individual child
• Google processes this data as a service provider acting on our behalf — not as an independent third party
• Google is contractually prohibited from using this data for its own commercial purposes
• Firebase may use installation identifiers solely for internal operations as permitted under COPPA (16 CFR 312.5(c)(7))

2. What We Don't Collect

• Children's names, ages, or birthdates
• Location data (no GPS, no IP-based geolocation, no approximate location)
• Contacts, phone numbers, or messages
• Photos, videos, or audio recordings (camera motion detection produces a number, not an image)
• Advertising IDs or any identifiers used for ad targeting
• Browsing history or activity outside the app
• Purchase or financial information (there are no in-app purchases)

We do not use any advertising SDKs, social media integrations, or third-party behavioral tracking tools. We do not share children's data with third parties for commercial, advertising, or AI training purposes.

3. How We Use the Data We Collect

Data	Purpose
Local game progress	Save your child's brushing streaks, unlocked heroes, and settings so they persist between sessions
Cloud backup data	Let parents back up and restore game progress across devices or after reinstalling the app
Parent's email and name	Identify the cloud save account and display it in Settings
Camera motion score	Adjust in-game attack frequency based on brushing movement during gameplay
Crash reports	Find and fix bugs to keep the app working reliably
Usage analytics	Understand how the app is used in aggregate so we can improve it for all families

We do not use any collected data for advertising, profiling, or any purpose other than operating and improving Brush Quest.

4. How We Protect Your Data

Data	Where Stored	Protection
Game progress	On your device	Protected by your device's lock screen and built-in encryption
Cloud backup	Google Cloud Firestore (US)	Encrypted in transit (TLS) and at rest. Security rules ensure each user can only read/write their own data
Crash reports	Google Firebase (US)	Anonymous — no personal data included. Protected by Google infrastructure security
Analytics	Google Firebase (US)	Anonymous, child-directed mode. No advertising IDs. Cannot identify individuals
Camera frames	Not stored anywhere	Processed in device memory only, discarded immediately after producing a motion score

Data Security Practices

In compliance with COPPA (16 CFR 312.8), we maintain reasonable procedures to protect the confidentiality, security, and integrity of children's personal information, including:

• Designated personnel responsible for data protection
• Risk assessment for internal and external threats to children's data
• Encryption in transit and at rest for all cloud-stored data
• Firestore security rules that enforce per-user data isolation
• Annual review and updates to our security practices

5. Third-Party Services

Brush Quest uses a small number of Google Firebase services to operate. These are the only third parties that process any data:

Service	Purpose	What It Processes
Firebase Authentication	Optional Google Sign-In for cloud backup	Parent's email address, display name, and UID
Cloud Firestore	Cloud backup storage (optional)	Game progress data (brushing history, stars, unlocks)
Firebase Crashlytics	Automatic crash reporting	Device info and error details (anonymous, no personal data)
Firebase Analytics	Anonymous usage understanding	Aggregated app events. No ad IDs. Child-directed mode enabled

All Firebase services act as service providers under our direction. They process data on our behalf and are contractually prohibited from using it for their own independent commercial purposes. No children's personal information is shared with third parties for advertising, profiling, or sale.

6. Children's Privacy (COPPA Compliance)

Brush Quest is designed for children ages 4–8 and fully complies with the Children's Online Privacy Protection Act (COPPA), including the 2025 amendments (16 CFR Part 312).

How we protect children

• We do not collect personal information directly from children
• The app works fully offline with no account, no sign-in, and no personal data collection
• All optional data collection features (cloud backup, camera) require a parent to enable them
• The camera is disabled by default and produces only a motion score — not biometric data
• Children cannot make their information publicly available
• We never condition a child's participation in the app on disclosing more data than necessary
• There are no social features, no chat, no user-generated content, and no links to external websites within the app
• There are no in-app purchases

Parental consent

We obtain verifiable parental consent before collecting any personal information:

• Parental gate: The Settings screen (where cloud backup and camera options live) is protected by a math verification problem designed to prevent unsupervised child access
• Consent dialog: Before enabling cloud backup, a clear dialog explains what data will be stored, where it will be stored, and links to this privacy policy. The parent must actively tap "I Consent" to proceed
• Camera notice: Before enabling motion detection, a notice explains how it works and confirms no images are stored

Anonymous crash reports and usage analytics are collected under COPPA's internal operations exception (16 CFR 312.5(c)(7)) — they support the app's internal operations and do not involve collecting personal information from children.

Your rights as a parent

Under COPPA, you have the right to:

• Review your child's information — Game progress is visible on the home screen and in Settings. Cloud data is accessible by signing in to your Google account. You can also email us for a complete summary
• Delete all data — Use "Delete child's data" in the app's Settings to erase all local data and all cloud data simultaneously. You can also request deletion by email
• Refuse further collection — Sign out of Google to stop cloud syncing. Disable the camera in Settings. The app continues to work fully offline with no data collection
• Withdraw consent — You can withdraw consent at any time by signing out and/or deleting data. We will not penalize your child's experience — the app works the same with or without cloud backup

We respond to all parental requests within 30 days. Email us at jim@anemosgp.com.

7. Google Play Families Policy

Brush Quest participates in Google Play's Designed for Families program and complies with the Families Policy requirements:

• The app is appropriate for children ages 4–8
• All content is suitable for the target age group
