1. Introduction & Privacy-First Architecture
Tech2U Savannah ("we", "our", or "us") develops Doomscroll Receipt: Screen Time (Package: com.tech2u.doomscrollreceipt) with an uncompromising local-first, privacy-by-default architecture.
Doomscroll transforms your daily digital screen habits into a humorous, itemized "checkout bill" and receipt, helping you quantify your digital attention and scroll debt without compromising your privacy.
Core Privacy Guarantee: Your screen time, app usage statistics, installed applications list, and generated receipts are processed strictly locally on your physical device. We do not operate external database servers that harvest, store, or sell your device activity logs.
2. Usage Access Permission & On-Device Processing
To generate accurate receipts reflecting how much time you spent on your phone, Doomscroll requests the Android Usage Access permission (android.permission.PACKAGE_USAGE_STATS).
- What It Does: It allows Android's local operating system API (
UsageStatsManager) to calculate how many minutes each application was in the foreground during today's or this week's billing cycle. - Where Processing Happens: 100% on your device. Android queries the operating system locally, formats the duration into itemized categories, and renders the thermal receipt canvas on your screen.
- Never Transmitted: Your usage stats, application timestamps, and app titles are never transmitted over the internet or shared with third parties.
3. Information We Do Not Collect
Doomscroll does not collect or store:
- Personal Identifiable Information (PII) such as full legal name, physical address, email address, phone number, or government IDs.
- Content viewed inside other applications (e.g., messages, browser history, passwords, financial credentials, camera/photos).
- Real-time GPS coordinates or background location tracking.
- Contact books, SMS history, or microphone audio.
4. Advertising & Analytics (Google AdMob & UMP)
Doomscroll is a free utility supported by advertising via the Google Mobile Ads SDK (AdMob). We implement Google's User Messaging Platform (UMP) SDK to ensure complete compliance with global privacy regulations, including EU GDPR, UK GDPR, Swiss DPA, and US State Privacy Laws (CCPA/CPRA).
| Partner / SDK | Purpose | Privacy Policy |
|---|---|---|
| Google Mobile Ads (AdMob) | In-app Banner & Interstitial Advertisements | Google Ad Policies |
| Google User Messaging Platform (UMP) | Consent Management & Privacy Choice Control | Google Privacy Policy |
AdMob may collect advertising identifiers (GAID) and coarse diagnostic telemetry in accordance with your consent choices. You can review or modify your consent settings at any time via the "Consent Preferences" / "Privacy Settings" option in Doomscroll's Settings screen.
5. Local Scheduled Notifications
Doomscroll includes an optional daily morning reminder (e.g., 9:00 AM) to encourage digital mindfulness and reviewing your yesterday's scroll receipt. This notification is scheduled and delivered entirely offline via Android's local alarm scheduler (flutter_local_notifications). No remote push servers, FCM device tokens, or tracking payloads are utilized.
6. User Rights & Consent Revocation
Under international privacy frameworks (GDPR, CCPA/CPRA), you retain complete control over your preferences:
- Consent Revocation: You can open Settings → Privacy Settings in the app at any time to invoke Google's UMP consent form to change or withdraw your consent.
- Permission Revocation: You can revoke the Android Usage Access permission at any time directly in your Android OS Settings under Apps → Special App Access → Usage Access.
- Right to Erasure: Tap "Reset All Data" inside Doomscroll's Settings to instantly purge all stored preferences and cached calculations.
7. Children's Privacy
Doomscroll does not target or knowingly collect data from children under the age of 13 (or under 16 in the EEA/UK). Because no personal data or usage logs are collected or stored on remote servers, children's privacy is preserved by default.
8. Data Retention & Deletion
Because all data resides exclusively in your device's isolated local application storage, uninstalling Doomscroll or clearing app cache and storage in Android settings permanently and irreversibly erases all data.
