1. Information We Collect

1.1 Information You Provide

OmniTimer is designed with privacy in mind. All your personal timer data is stored locally on your device only and is never transmitted to our servers. This includes:

• Custom timer presets and configurations (names, intervals, durations, sounds, images, skip rules)
• Timer session history (elapsed time, pause count, intervals completed/skipped)
• App settings and preferences (theme, font, accessibility, timer behavior, notification preferences)
• Custom sounds and color configurations
• Training program enrollments and day completion tracking
• AI preset generation settings (backend type, model selection, API keys — entered by you, stored locally)
• Downloaded AI models (GGUF files stored in the app's documents directory)
• Export data (CSV files and shared presets remain on your device or are shared via the system share sheet — they are never uploaded to our servers)

No user accounts are required. OmniTimer does not collect your name, email address, phone number, or any other personally identifiable information (PII).

1.2 Automatically Collected Information

When you use OmniTimer, certain information may be automatically collected by third-party services integrated into the App:

Firebase Analytics (when enabled)

If you have analytics enabled (configurable in Settings), the following usage events are collected:

• Timer Lifecycle: Timer started, paused, resumed, stopped, completed, restarted (including preset name, interval count, and duration)
• Preset Management: Preset created, updated, deleted, duplicated, shared, exported, imported (including counts)
• Session Data: Sessions exported, imported, cleared (including counts)
• Paywall Events: Paywall opened, purchase completed, purchase restored
• Settings Changes: Setting name and value when changed, settings reset
• User Properties: Pro subscription status (boolean)

You can disable analytics collection at any time via Settings → Data & Privacy → Analytics. When disabled, no analytics events are sent to Firebase.

Firebase Crashlytics

Crash reports and error logs are collected automatically in release builds to help us identify and fix bugs. This includes:

• Stack traces and error messages
• Device model and operating system version
• App version and build number
• Environment identifier (development/production)

Crash reporting is disabled in debug/development builds.

Device Information

• App version (displayed in the About page via package_info_plus)
• Locally generated UUIDs for presets and tags (these are app-local identifiers, not device identifiers)

We do not directly collect device model, manufacturer, operating system version, or hardware identifiers. However, third-party SDKs (Firebase, AdMob) may collect such information as described below.
