Zero Sugar – Support & Privacy

Zero Sugar is a simple habit tracker that helps you complete sugar‑free challenges. Set a challenge length, check in once per day, and track your streak on a clean calendar.

How to Use Zero Sugar

1. Start a challenge

• Choose a challenge duration (for example 7, 14, or 30 days).
• Confirm your start date to begin.

2. Check in each day

• Open the app once a day.
• Mark the day as Success or Failed.
• Optionally add a note about how you felt or what you ate.

3. Track your streak

• Use the Tracking screen to see successful, failed, and upcoming days.
• Watch your streak grow and see how long you’ve stayed sugar‑free.

4. Turn on reminders (optional)

• Go to the Settings tab.
• Enable daily notifications so you don’t forget to check in.

Frequently Asked Questions

Does the app track calories or specific foods?

Yes. All core features work offline because your data is stored locally on your device.

What happens if I delete the app?

All of your locally stored data (challenges, check‑ins, and notes) will be removed from your device when you uninstall the app.
