Habit Lantern Privacy Policy

Last updated: April 30, 2026 · Effective: April 30, 2026

Habit Lantern is built privacy-first. Your data lives on your device, full stop. This policy explains exactly what that means, what we don't do, and the one small exception (ads) that we handle transparently.

The Short Version

We don't collect your personal data. No accounts, no sign-ups, no analytics.
Your habits, stats, streaks, and character data stay on your device. We never see them.
We show ads via Google AdMob in the free version. AdMob may collect non-personal identifiers for ad serving — this is the only third-party data flow in the app.
Premium users see zero ads and no third-party SDKs are loaded.
You can export your data anytime as a local backup file. You can uninstall the app to permanently delete all your data.

What Habit Lantern Stores on Your Device

The following information is created and stored only on your device using the Hive local database:

Your character name, level, XP, and avatar choice
The habits you create (name, icon, category, schedule, reminder times)
Your completion history (dates when habits were completed)
Your streak counts and achievements unlocked
App preferences (theme, haptic feedback, notification settings)

None of this information is transmitted to us, to any server, or to any third party. If your phone is offline, the app still works perfectly — because there's nothing to send.

What We Don't Collect

No personal identifiers (name, email, phone)
No location data
No contacts, photos, or files from your device
No analytics events (taps, screen views, session length)
No crash reports
No device fingerprinting

Ads (Free Version Only)

To keep the free version sustainable, we display ads using Google AdMob. This is the only third-party SDK in the app. When ads are served, Google may process:

Your Advertising ID (a resettable, non-personal identifier controlled by your device settings)
Approximate location derived from IP (for ad relevance and legal compliance)
Basic device information (OS version, device model)

This is standard AdMob behavior and is subject to Google's Privacy Policy. You can opt out of personalized ads at any time via your device's settings, and we fully support Google's User Messaging Platform (UMP) consent requirements where applicable (GDPR, CCPA).

Premium users do not see ads. When Premium is active, AdMob is not initialized and no ad-related data flows through the app.

Notifications

Habit Lantern schedules reminders using Android's local notification system. All notification logic runs on your device — no push server, no FCM token, no remote dispatch. If you deny notification permission, the rest of the app continues to work without issue.

Data Export & Deletion

You own your data. Inside Settings → Data you can:

Export Data — save all your habits and progress to a local backup file
Import Data — restore from a previous backup
Share Backup — share your progress file via any app
Reset Progress — wipe everything and start fresh

To permanently delete all your Habit Lantern data: simply uninstall the app. Since nothing is stored on our servers, uninstallation is complete data erasure.

Children's Privacy

Habit Lantern is rated suitable for ages 13+ (Teen). We do not knowingly collect information from children under 13. Because we don't collect any personal data at all, this compliance is structural: there's simply nothing to collect.

Changes to This Policy

If we ever change this policy — for example, if we add an optional crash reporting feature in a future version — we will update this page and notify users through an in-app message before the change takes effect. We will never retroactively apply new data collection to previously-collected data.
