Everything stays on your device. MergeKey never connects to the internet. The only network activity is the App Store handling the optional tips – that's why iOS shows a Mobile Data switch for MergeKey. Word lists based on the Leipzig Corpora Collection (CC BY 4.0).

Verdict
The clearest difference is in-app purchases: MergeKey at none against MatrixQR's 2. MatrixQR's advantage is update cadence (daily vs weekly) and iOS requirement (13.0 vs 18.0). On price, ads and device support there is nothing between them.
