Data Deletion Request

Step 1 — Delete Local Data

Uninstall the Abak Crypto & Stock Calculator app from your device. All locally stored data (settings, preferences, calculation history) will be removed automatically.

• Android: Long-press the Abak icon → Uninstall (or go to Settings → Apps → Abak Crypto & Stock Calculator → Uninstall)

If you want to keep the App but only clear stored data: Settings → Apps → Abak Crypto & Stock Calculator → Storage → "Clear data".

Step 2 — Reset Advertising Identifier (Optional)

To prevent further ad-related data collection by Google AdMob:

• Android: Settings → Google → Ads → Delete advertising ID (or Reset advertising ID)

Step 3 — In-App Purchase (Remove Ads)

If you've made the one-time in-app purchase to remove ads, that record is kept by your Google Play account, not by us. Purchase history can be reviewed or managed through:

• Google Play Order History

For refund or purchase deletion requests, please contact Google Play support directly.
