This privacy policy applies to the Android mobile application Oasis Minimalist Launcher (identified by package name com.umbrabyte.minimalist.launcher), developed and published by Umbrabyte Apps (operated by sole proprietor Cristian Donet Segura). It complements the general Umbrabyte Privacy Policy and constitutes the official, binding privacy policy linked inside the mobile application and displayed within its Google Play Store listing.

Plain language summary: Oasis Minimalist Launcher turns your phone into a calm, distraction-free space for focus and intentional living. All app indexing, screen time counting, notification digests, blocked app schedules, and custom preferences are processed and stored strictly locally on your device in SQLite Room and Android DataStore. Umbrabyte operates no external servers to intercept or monitor your phone usage, requires no user account, includes zero advertisements, and never sells or rents personal data. Data only leaves your device when Google Play processes an optional Oasis PRO subscription/purchase or when you contact direct support.

This plain-language summary is provided for clarity and does not replace the comprehensive legal and technical terms set forth below.

1. Scope and key facts

Oasis Minimalist Launcher is an ethical, typography-first Android home screen and digital wellbeing utility. It replaces dopamine-triggering interfaces, red notification badges, and infinite algorithmic feeds with a clean, distraction-free environment, an alphabetical A-Z app drawer, notification batching, app time limits, mindful breathing pauses, and contextual focus profiles.

• No user account or login credentials: The core launcher never asks you to create an account, profile, provide an email address, or enter personal credentials.
• 100% On-Device Local Processing: Screen time counting, usage analytics, app categorization, notification filtering, and quiet schedules operate entirely on your physical hardware.
• No Umbrabyte cloud infrastructure: Umbrabyte does not own, operate, or maintain intermediate backend servers, telemetric databases, or user-tracking pipelines. Your list of installed applications and personal digital habits are never uploaded to remote servers.
• Zero advertisements or marketing trackers: The application contains zero advertising SDKs, commercial tracking libraries, or affiliate monitors. The application manifest explicitly strips (tools:node="remove") permissions associated with advertising identifiers (AD_ID and AdServices).
• No data sales or commercial broker sharing: Umbrabyte does not sell, rent, lease, or trade user personal information or behavioral insights under any circumstances.
• No automated profiling or surveillance: We do not conduct automated profiling, behavioral scoring, or automated decision-making.
• Platform integration: Optional Oasis PRO purchases and subscriptions are handled securely via official Google Play Billing APIs. In-App Update checks utilize official Google Play Core APIs.

3. Data processed by the application

3.1 Information stored and processed strictly on device

The application operates locally on Android using Jetpack Room Database (OasisDatabase) and Android Jetpack DataStore. All records are isolated within the private sandbox storage of the app:

3.2 Android permissions and device capabilities

Android permissions are requested transparently with contextual rationale only when you access a feature that requires them. No sensitive permission is required for the basic home screen launcher:

The application does NOT declare or request GPS location, contacts list, call logs, SMS, microphone recordings, health data, advertising identifier (GAID), photos, or biometric templates (biometric authentication is verified via native Android BiometricPrompt).

3.3 Data Umbrabyte does NOT receive

During standard use of Oasis Minimalist Launcher, Umbrabyte does not receive, intercept, or store on servers:

• Your installed applications or app usage frequency.
• The content, body, or sender of your notifications.
• Your search queries in the A-Z drawer.
• Your calendar events, notes, detox commitments, or screen-time history.
• Biometric information (fingerprint/face data remains strictly protected within Android hardware keystore).

4. External services & monetization terms

4.1 Distribution and payments via Google Play Billing

Oasis Minimalist Launcher is free to download and use. Optional Oasis PRO tiers are offered via official Google Play Billing (version 7.x):

• Billing terms: Payments, tax calculation, currency conversion, and receipt delivery are handled entirely by Google Play. Umbrabyte never receives or stores credit card numbers, bank details, or payment credentials.
• Subscription management & cancellation: Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing cycle. Users can manage or cancel subscriptions at any time directly through Google Play Store > Payments & subscriptions.
• Refund policy: All purchases and refund requests are governed by the Google Play Refund Policy.
• Free tier guarantee: The core launcher (clock, home screen, A-Z drawer, text search, opening apps, notification filter, daily time limits, today and 7-day screen time, all 10 canvas themes, and 34 languages) is free forever. No configured settings are deleted when PRO expires.

4.2 In-app updates via Google Play Core

The app integrates official Google Play Core APIs (app-update-ktx) to communicate securely with Google Play Store via Android IPC and check for new releases.

4.3 Third-party SDKs and telemetry policy

Oasis contains zero third-party marketing, tracking, or analytical SDKs (no Firebase Analytics, Mixpanel, AppsFlyer, Facebook SDK, or AdMob). Transitive network traffic is limited strictly to Google Play Services for payment processing and update verification over TLS 1.3 / HTTPS.

5. Purposes and legal bases

Under the European Union General Data Protection Regulation (GDPR / RGPD) and UK GDPR, processing activities rely on:

6. Data retention, deletion & management

The application declares allowBackup="false" to prevent unencrypted cloud extraction by third-party backup tools. All data remains strictly under user control.

7. Data security

• Operating system sandboxing: All local databases and DataStore files are isolated within Android’s private UID sandbox.
• Encryption at rest: Databases and preferences utilize OS-level hardware-backed encryption.
• Encryption in transit: All network communication with Google Play services uses HTTPS / TLS 1.3.
• Cleartext traffic prohibited: android:usesCleartextTraffic="false" is enforced across the entire application manifest.
