Privacy Policy

Effective date: May 9, 2026. Last updated: June 11, 2026.

Short version: No Sugar is local-first. Your habit data starts on your device. If you choose account, sync, Pro purchase, analytics, or AI coaching features, the minimum data needed for those features is processed by the services described below. We do not sell your data, show ads, or use ad tracking identifiers.

1. Who we are

No Sugar is an independent mobile app operated by Praveen Kumar S. Contact: c2praveen30jun@gmail.com.

2. Data you provide or create

Optional display name, mascot name, goals, motivations, and reminder preferences.
Daily check-ins, clean/slip status, selected triggers, mood, streak history, and optional notes.
Craving journal entries you write in the SOS toolkit.
Email address and authentication records if you create an account for cloud backup and sync.
Purchase entitlement status if you buy or restore No Sugar Pro.
Analytics preference when you choose whether to share anonymous product analytics.

3. Data we do not collect

No location tracking.
No contacts, photos, camera, microphone, HealthKit, or Google Fit data.
No advertising SDKs, ad tracking, IDFA, or GAID collection.
No sale of personal information.

4. Local storage and cloud sync

By default, No Sugar stores your habit data on your device. If you create an account or enable cloud backup/sync, your app data is synced to Supabase so you can restore it or use it across your own devices. Supabase data is protected with row-level security and encrypted in transit.

5. No Sugar Pro purchases

No Sugar Pro purchases and restore status are handled through Apple App Store or Google Play billing and RevenueCat. We receive purchase entitlement information such as whether Pro is active, the product purchased, renewal status, and store transaction metadata needed to unlock paid digital features. We do not receive your full payment card details.

6. AI coaching features

No Sugar Pro may include controlled AI-generated coaching features, such as a tomorrow prevention plan, weekly coaching nudge, post-slip reflection, or monthly pattern summary. To generate these, the app sends a limited structured habit-pattern payload to our Supabase Edge Function. This may include items such as clean percentage, recent slip category, top trigger, risky time window, trend, streak context, and saved or worked alternative counts. The function calls OpenAI to produce a short habit-support response.

The AI coach does not need your full journal text for these coaching nudges. AI output may be imperfect and is for general wellness support only. It is not medical advice, diagnosis, or treatment.

7. Crash reporting and analytics

Sentry may be used for crash reporting when configured in production builds. We configure it to avoid unnecessary personal identifiers where possible.

PostHog product analytics is optional and off by default. It is only initialized if you enable "Share anonymous analytics" in Settings. Journal text is not sent as product analytics.

8. Third-party services

Supabase: database, authentication, sync, and Edge Functions.
OpenAI: AI-generated coaching, only for Pro AI features.
RevenueCat: purchase entitlement management.
Apple App Store / Google Play: billing and subscription management.
Expo / EAS: builds and over-the-air updates.
Sentry: crash reporting, if configured.
PostHog: optional product analytics, only after opt-in.

9. How we use data

To show your streak, calendar, stats, recaps, and in-app progress.
To schedule local reminders at the time you choose.
To sync or restore your data when you use account features.
To unlock, restore, and manage Pro features.
To generate Pro AI coaching when available.
To diagnose crashes and improve reliability.
To understand aggregate feature usage only if analytics is enabled.

10. Your choices and rights

Use the app without creating an account.
Disable analytics any time in Settings.
Export your data from the app.
Delete your account and synced data from Settings when signed in.
Cancel or manage subscriptions through Apple or Google account settings.
Email us for privacy requests that are not available in the app.

11. Data retention

Local data remains on your device until you delete it or uninstall the app. Synced cloud data remains while your account is active unless you delete it. Crash, analytics, and purchase records are retained according to the policies of the providers listed above and our operational needs.

12. Children's privacy

No Sugar is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

13. Changes

We may update this policy as the app evolves. The last updated date above reflects the current version.
