90% of rummy-app horror stories are install-source problems — not game problems. Parent: download guide.
Download from the platform's own HTTPS website. Verify each character of the domain — scammers use lookalikes (o/rn swaps).

Run Play Protect / a reputable scanner on the downloaded APK before opening it.
A rummy app needs storage & network. If it asks for contacts, SMS or accessibility access — abort.
