Your translation app sends every little thing to the cloud, however this one retains all of it in your telephone
While many apps and services leverage cloud processing to offload the heavy lifting to servers, this isn’t ideal for sensitive data. The most personal information your smartphone handles should stay on your device whenever possible. This includes your private conversations, but if you use a transcription or translation app, they could be sent to the cloud for processing. By default, popular translation apps use a mix of on-device and off-device processing.
