Privacy Policy

Effective: 23 May 2026 · Slice & Solve mobile app

1. What we don't collect

We do not collect any of the following:

• Personal identifiers (name, email, phone number, account credentials)
• Device identifiers (advertising ID, IDFA, device serial number)
• Location data
• Photos, contacts, or other device content
• Usage analytics or telemetry
• Crash reports containing personal information
• Health or biometric data

2. What stays on the device

To make the app work, the following information is stored locally on your child's iPhone or iPad, and only there. It is never transmitted off the device:

• The player's chosen name (or display name)
• The player's avatar customization (color, hair, face)
• The player's age band (used to set puzzle difficulty)
• Game progress: level, XP, coins, stars, streaks, problem history
• Multiple profiles (if siblings share the device)

This data is stored using the device's local storage. Uninstalling the app deletes all of it. It is never sent to us or any third party.

3. Children's privacy

Slice & Solve is designed for children ages 5–12. Because we do not collect any personal information, Slice & Solve complies with the U.S. Children's Online Privacy Protection Act (COPPA) and similar regulations such as the GDPR-K provisions for children under 16 in the European Union.

There are no accounts, no sign-ups, no logins, no chat features, no in-app purchases, no advertisements, and no links to external websites or services.

4. Third-party services

Slice & Solve uses Apple's built-in text-to-speech engine (AVSpeechSynthesizer) to read questions aloud when the speaker icon is tapped. Text passed to the speech engine is the same prompt text shown on screen, and is processed locally by iOS. We do not use any third-party analytics, advertising, tracking, or crash reporting SDKs.

5. Data sharing

We do not sell, rent, lease, share, or otherwise transfer any information to third parties — because we do not have any to share.

6. Changes to this policy

If we ever update Slice & Solve in a way that changes what data is handled, we will update this page and bump the "Effective" date at the top. Material changes will also be noted in the App Store release notes for the affected version.
