This Privacy Policy describes how we handle information in our app, in compliance with Law 81 of March 26, 2019 "On the Protection of Personal Data" of the Republic of Panama.
By using our app, you accept the practices described in this Privacy Policy. If you do not agree with these practices, please do not use our app.
Happy Levels is designed with privacy as a core principle. We do not collect, transmit, or store any of your personal data on our servers. All your level data (titles, emojis, schedules) stays on your device, under your control.
We collect anonymous usage analytics to improve the app experience. This analytics data contains no personal information and can be disabled at any time in Preferences.

User or Data Subject: Natural person who uses Happy Levels.
Personal Data: Any information concerning identified or identifiable natural persons.
Local Storage: Data stored exclusively on your device, not transmitted to any servers.
To improve Happy Levels and understand how users interact with the app, we collect anonymous usage analytics via Firebase Analytics. This data is aggregated and cannot be traced back to you as an individual.
Analytics data includes:
Anonymous usage events (e.g., level created, level refilled, theme changed)

We do NOT collect any personal or identifiable information:
Your name, email address, or contact information
Your level titles, emojis, or content
Your exact schedules or refill times
Your device identifiers for cross-app tracking
Your location data
Your IP address
Any personally identifiable information
You can disable analytics collection at any time:
Open the menu (☰ icon)
Go to Preferences

When disabled, no analytics data will be collected or transmitted.
All data in Happy Levels is stored locally on your device using Apple's SwiftData framework (iOS) or equivalent local storage (Android). This includes:

Data is not automatically backed up to our servers
You are responsible for backing up your data (via iCloud or device backup)
Happy Levels offers optional in-app purchases (subscriptions and lifetime purchase). These transactions are processed entirely by:
Apple App Store (for iOS users)
Google Play Store (for Android users)
We receive anonymous purchase validation from Apple/Google to verify your subscription status. This includes:
A transaction identifier (not linked to your identity)

Happy Levels offers home screen widgets that display your levels. Widget data:
Is stored and rendered locally on your device
Uses the same local data as the main app
Does not communicate with any servers
Is shared between the app and widget using Apple's App Groups feature (iOS only)
We do not collect your personal data (level titles, content, schedules), so we have nothing to share. Your level data stays on your device.

Purpose: Anonymous usage analytics
Data collected: Non-identifiable app usage events (see Section 3.1)
Privacy Policy: Google Privacy Policy

Since we do not possess your personal data or level content, we cannot provide it to authorities even if legally requested. Your content data exists only on your device. Anonymous analytics data is aggregated and cannot be attributed to specific individuals.
Under Panama's Law 81 of 2019, you have the following rights regarding your personal data:
You have full access to all your data through the app interface. We cannot provide you with data we don't possess.
You can edit, modify, or correct all your level data directly in the app at any time.
You can delete individual levels or all your data by:
Deleting individual levels in the app
Deleting the entire app from your device (this removes all local data)
You can oppose anonymous analytics collection by:
Opening Preferences from the menu
Toggling off "Anonymous Usage Analytics"
For your level data, since it's stored only on your device, there is no server-side data processing to oppose.
Currently, your data can be backed up through:
iOS: iCloud backup or iTunes backup
Android: Device backup or Google backup
We may add export features in future updates.
Your data security depends on your device security:
Use device passcode/biometric authentication
Keep your device operating system updated
Use device encryption (enabled by default on iOS and modern Android)
Since we don't store data on servers, there are no server security risks such as:
Data breaches
Unauthorized server access
Hacking attempts on databases
We are not responsible for data loss resulting from:
Device loss, theft, or damage
Factory resets without backups
Operating system issues
Uninstalling the app without backing up data
Important: We strongly recommend using your device's backup features (iCloud, iTunes, Google backup) to prevent data loss.
