🎯 Data Deletion Request — Roulette Stat Master

App: Roulette Stat Master | Developer: Manav Arora | Last updated: 12 May 2026

1. Overview

This page explains how users of Roulette Stat Master (published by Manav Arora, package com.airoulette.predictor) can request deletion of their data. Because the app is offline-first, almost all of your data lives only on your device. A small amount of anonymous data is sent to Google Firebase (crash reports, anonymous analytics, anti-piracy record); this page also covers how to remove the server-stored portions.

2. What data exists, and where

Data	Where it lives	How to delete
Spin-by-spin session history (the roulette numbers 0–36 you entered)	Your device only (app's private documents folder)	Step A or Step B below
Bankroll, base bet, P&L tracking (local simulation)	Your device only (private SharedPreferences)	Step A or Step B below
App preferences (theme, language, prediction mode, walkthrough state)	Your device only	Step A or Step B below
Optional OpenAI / Gemini API key (only if you enabled External AI)	Your device only (encrypted via Android Keystore / iOS Keychain)	Step A or Step B below
Anti-piracy record: server-stored hash of your device identifier, free-prediction count, UTC offset, last-updated timestamp	Our Firebase Realtime Database at `prediction_guards/<hash>`	Step C below
Anonymous crash reports (stack traces, device model, OS version)	Firebase Crashlytics (Google)	Auto-expires (90 days) · or Step D below
Anonymous screen-view analytics (screen names, app version)	Firebase Analytics (Google)	Auto-expires (14 months) · or Step D below

3. How to request deletion

Step A — Uninstall the app (deletes ALL data stored on your device)

Long-press the Roulette Tracker icon on your Android device.
Tap Uninstall (or drag the icon to the "Uninstall" target).
Confirm.

This permanently removes every byte of on-device data: sessions, bankroll history, preferences, secure API keys — everything.

Step B — Clear app data (keeps the app installed but wipes its storage)

Open Android Settings → Apps → Roulette Tracker.
Tap Storage & cache.
Tap Clear storage (or "Clear data") and confirm.

This wipes all on-device app data while leaving the app installed. You can also clear sessions selectively from within the app: Settings → Session History → Clear all sessions.

Step C — Request server-side deletion of your anti-piracy record

To remove the hashed device identifier and free-prediction record we keep for anti-piracy:

Send an email to apps3mb@gmail.com with the subject line "Data Deletion Request — Roulette Stat Master".
In the email, include either:
- your Google Play order ID for the most recent purchase (Premium subscribers), or
- the date you last used the app and your device model (free users — this helps us locate the record).
We will permanently delete the matching prediction_guards/<hash> record from Firebase Realtime Database and reply to confirm.

Response time: within 30 days of receipt of your request (typically within 7 days).

Step D — Request deletion of anonymous Crashlytics / Analytics data

Anonymous crash reports and aggregate analytics events do not contain personal identifiers and auto-expire on Firebase's standard schedule (90 days for crashes, 14 months for analytics). If you wish to request earlier deletion:

Email apps3mb@gmail.com with the subject "Firebase Data Deletion Request — Roulette Stat Master".
Include your device model, OS version, and the approximate dates you used the app — this helps us identify the records.
We will request deletion via the Firebase Console and confirm.

You can also opt out of Google Play Services analytics at any time via Android Settings → Google → Ads / Usage & diagnostics.

4. What gets deleted vs. retained

4.1 Data that is fully deleted on request

All on-device data (Step A or B) — sessions, bankroll, preferences, encrypted API keys.
Server-side anti-piracy record (Step C) — hashed device identifier, prediction count, UTC offset, timestamp.
Firebase Crashlytics / Analytics records (Step D) — anonymous, on request before auto-expiry.

4.2 Data that may be retained, and why

Google Play subscription / purchase records: Handled by Google Play. We do not control or store payment information; Google retains transactional records under its own policies. To delete Google Play data, use Google's Account & Privacy controls.
Email correspondence: If you contact us by email, we retain the email thread for 12 months for support quality and audit purposes, then delete it.
Aggregated, non-identifying counters: If you have used the app, anonymous daily-aggregate counters (e.g., total free predictions issued site-wide on a given date) may persist in our system. These cannot be linked to you because the device identifier has been deleted.

5. External AI providers (only if you enabled External AI)

If you enabled the optional External AI feature and used it with your own OpenAI or Google Gemini API key, request data deletion directly from those providers — we never see, store, or have access to data you sent to them:

OpenAI: privacy.openai.com
Google Gemini: Google Privacy & Terms

6. Retention period for the anti-piracy record

If you do not contact us, the anti-piracy prediction_guards/<hash> record remains in our database indefinitely. It contains no personal identifiers — only a one-way SHA-256 hash of a per-device value, a small integer (predictions used), a timezone offset, and a timestamp. There is no way for us to reverse the hash to identify a person.
