This page explains how users of Dragon Tiger Stat Master (published by Manav Arora) can request deletion of their data. Because the app is offline-first, almost all of your data lives only on your device โ but a small anti-piracy record is stored on our backend, and this page covers how to remove that too.
| Data | Where it lives | How to delete |
|---|---|---|
| Hand-by-hand session history (Dragon / Tiger / Tie outcomes you entered) | Your device only (app's private documents folder) | Step A or Step B below |
| Saved pattern rules and strategies you created | Your device only (private SharedPreferences) | Step A or Step B below |
| App preferences (theme, language, walkthrough state) | Your device only | Step A or Step B below |
| Anti-piracy identifier (iPhone and iPad only): one opaque device value | Your device's system Keychain โ survives app deletion by design | See the note in Step A |
| 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 |
This permanently removes all of your personal app data: sessions, pattern rules, preferences โ everything you entered or created.
One exception, on iPhone and iPad only. To stop the free-prediction allowance being reset by deleting and reinstalling the app, the anti-piracy identifier is kept in the system Keychain, which iOS deliberately preserves when an app is removed. It is a single opaque value: no session data, no personal information, and nothing readable by any other app. It is the only thing that survives Step A, and reinstalling the app reuses it rather than issuing a new one. iOS does not give apps or users a way to clear an individual Keychain entry from outside the app, so it goes only when the device itself is erased (Settings โ General โ Transfer or Reset iPhone). On Android nothing survives โ uninstalling removes everything.
iOS has no per-app "clear data" control. On iPhone and iPad use Step A instead โ uninstalling removes exactly the same on-device data.
This wipes all on-device app data while leaving the app installed.
Read this first, because it decides whether you need Step C at all. The record is stored under a one-way SHA-256 hash of a device value. It contains no name, no email address, no device model and no order or transaction number โ only that hash, a count of free predictions used, a timezone offset and a timestamp. We cannot search it by your name, your email or your purchase, and we cannot reverse the hash to work out whose it is. Nothing in it identifies you, to us or to anyone else.
That also means we must be straight with you about what we can and cannot do:
Android ID or SSAID, a 16-character hexadecimal value. Email it to apps3mb@gmail.com and we will hash it, delete the matching prediction_guards/<hash> record, and reply to confirm.You are under no obligation to send an Android ID. It is itself a device identifier, and declining to share one in order to delete one is a perfectly reasonable position.
Response time: within 30 days of receipt of your request (typically within 7 days).
If you do not contact us, the anti-piracy prediction_guards/<hash> record remains in our database indefinitely. It contains no personal identifiers โ 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.
