Privacy Policy

1. Introduction

Prio ("the App") is a privacy-first, AI-powered task management application for Android. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

2. Information We Collect

2.1 Information Stored Locally on Your Device (Never Sent to Us)

The following data is created and stored exclusively on your device. We never have access to it:

• Tasks: Task titles, descriptions, due dates, priorities, categories, and completion status
• Goals: Goal titles, descriptions, milestones, and progress
• AI Classifications: Eisenhower Matrix classifications generated by on-device AI
• Briefings: Daily morning and evening briefings generated on-device
• Calendar Data: Read-only access to your device calendar (only when you grant permission) — used to show events alongside tasks; never transmitted
• User Preferences: App settings such as theme, default views, and notification preferences

All locally stored data is encrypted at rest using SQLCipher (AES-256 encryption).

2.2 Information Collected Automatically (Anonymous)

We collect limited anonymous data to improve app stability and understand feature usage:

Data Type	Purpose	Service	Can Identify You?
Crash reports	Fix app crashes and improve stability	Firebase Crashlytics	No — anonymized stack traces, device model, OS version only
App performance data	Measure app startup time, screen load speed	Firebase Analytics	No — aggregated metrics only
Feature usage events	Understand which features are used (e.g., "task created", "goal viewed")	Firebase Analytics	No — event counts only, no task content

What we do NOT collect through analytics:

• Task titles, descriptions, or any user-created content
• Personal information (name, email, phone number)
• Location data
• Contact information
• Photos, files, or documents
• Browsing history

2.3 Information We Never Collect

• No account required: You can use Prio without creating an account or providing any personal information.
• No personal identifiers: We do not collect names, email addresses, phone numbers, or physical addresses.
• No device identifiers: We do not collect hardware IDs, advertising IDs, or device fingerprints for tracking.
• No location data: Prio does not request or use location permissions.
• No contacts: Prio does not access your contact list.
• No user-generated content: Your tasks, goals, notes, and AI briefings are never transmitted from your device.

3. How We Use Information

Use	Data Used	Legal Basis
Provide core app functionality	Locally stored tasks, goals, preferences	Contract performance (you use the app)
AI task classification	Task content processed on-device only	Contract performance
Fix crashes and bugs	Anonymous crash reports	Legitimate interest
Improve app features	Anonymous usage analytics	Legitimate interest
Process purchases	Google Play handles all billing data	Contract performance (via Google Play)

We do not use your data for:

• Advertising or ad targeting
• Selling to third parties
• Profiling or behavioral tracking
• Training AI models outside your device

4. On-Device AI Processing

Prio uses on-device artificial intelligence to classify tasks, generate briefings, and provide productivity insights.

• All AI processing happens on your device. No task content is sent to external servers for AI processing.
• AI models used: Google Gemini Nano (via Android AI Core, on supported devices) and llama.cpp (bundled with the app as a fallback). A rule-based classifier also operates entirely on-device.
• No cloud AI in the free or Pro tiers. Your data never leaves your device for AI purposes.

5. Third-Party Services

Service	Purpose	Data Shared	Privacy Policy
Google Firebase Crashlytics	Crash reporting	Anonymous crash logs (stack traces, device model, OS version)	Firebase Privacy
Google Firebase Analytics	Feature usage analytics	Anonymous event data (e.g., screen views, feature usage counts)	Firebase Privacy
Google Play Billing	In-app purchases and subscriptions	Handled entirely by Google Play — we do not process or store payment information	Google Privacy Policy
Google ML Kit	On-device AI (Gemini Nano)	No data shared — all processing is on-device	ML Kit Privacy

We do not use any advertising SDKs, social media trackers, or third-party analytics beyond Firebase.

6. Data Sharing

We do not sell, rent, or share your personal data with third parties.

The only data transmitted from your device is:

• Anonymous crash reports (to Firebase Crashlytics)
• Anonymous usage analytics (to Firebase Analytics)

No user-created content (tasks, goals, briefings) is ever transmitted.

7. Data Storage and Security

• Local storage: All user-created data is stored exclusively on your device.
• Encryption: User data is encrypted at rest using SQLCipher (AES-256 encryption).
• No cloud storage: Prio does not store your data on any external server (in the current version).
• No account: No passwords, credentials, or authentication tokens are stored.

8. Data Retention and Deletion

• Your data, your control: Since all personal data is stored on your device, you have complete control over it at all times.
• Delete data in-app: Use Settings → Delete All Data to permanently erase all tasks, goals, and preferences.
• Delete via Android: Go to Android Settings → Apps → Prio → Clear Data to remove all app data.
• Uninstall: Uninstalling Prio removes all locally stored data from your device.
• Analytics data: Anonymous analytics data retained by Firebase is not linked to you and cannot be individually deleted. Firebase retains aggregated analytics for up to 14 months.

9. Permissions

Permission	Purpose	Required?
Internet	Send anonymous crash reports and analytics; check for purchases	Yes (but app works offline)
Notifications	Send task reminders and due date alerts	Optional — requested at runtime
Exact Alarms	Schedule precise task reminders	Optional — requested when setting reminders
Boot Completed	Reschedule reminders after device restart	Automatic
Read Calendar	Show calendar events alongside tasks	Optional — requested at runtime
Record Audio	Voice input for quick task capture	Optional — requested at runtime
Vibrate	Haptic feedback for notifications	Automatic

All optional permissions can be denied without affecting core app functionality. You can revoke permissions at any time in Android Settings.

10. Children's Privacy

Prio is not directed at children under 13 (or the applicable age in your jurisdiction). We do not knowingly collect information from children. Our target audience is adults (18+).

11. In-App Purchases

12. Your Rights

Depending on your jurisdiction, you may have the following rights:

• Access: Know what data we have about you — since all personal data is on your device, you already have full access.
• Deletion: Delete all your data at any time (see Section 8).
• Portability: Export your data (available to Pro users).
• Opt-out of analytics: You can disable Firebase Analytics by restricting background data for the app in Android Settings, or by using a device with no internet connection.
• Withdraw consent: Revoke any optional permission at any time via Android Settings.

For EU/EEA residents: You may also lodge a complaint with your local data protection authority.

13. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. Continued use of the App after changes constitutes acceptance of the updated policy.

For significant changes, we will provide notice within the app.
