Privacy Policy — SustainWise

Last updated: 8 August 2026

SustainWise ("the app") is developed by an independent developer. This policy explains what data the app collects and how it's used.

Short version

SustainWise does not collect, store, or transmit any personal data. Everything the app tracks — your streak, XP, and lesson progress — stays on your device.

What the app stores

The app saves the following locally, on your device only, using standard Android app storage (SharedPreferences):

• Your current and longest daily streak
• Your total XP
• The date you last completed a lesson
• Which learning modules you've completed or unlocked

This data is never transmitted anywhere. It is not sent to the developer, to any analytics service, or to any third party. If you uninstall the app, this data is deleted along with it.

What the app does not do

• No account creation or sign-in is required or offered.
• No advertising or ad-tracking SDKs are included.
• No analytics or crash-reporting SDKs are included.
• No personal data (name, email, location, contacts, etc.) is requested or collected.
• No data is shared with third parties, because no data leaves your device.

Children's privacy

SustainWise is intended for a general professional and adult audience (sustainability, compliance, and finance topics) and is not directed at children. It does not knowingly collect data from anyone, including children, because it does not collect data from any user.

Changes to this policy

If the app's data practices change, this page will be updated and the "Last updated" date above will reflect the change.
