Text Message Filtering on iPhone

Text Message Filtering is the iOS setting that lets a trusted app classify messages from unknown senders. FingerWag uses this system to apply the filtering rules you choose.

Where to find the setting

On newer iOS versions, open Settings, Apps, Messages, then Text Message Filtering. On older versions, look under Messages, then Unknown & Spam.

What gets filtered

Message filters work on texts from unknown senders. Existing conversations and contacts are generally not filtered by third-party SMS filtering apps.

Why privacy matters

A text filter should not need to upload your messages. FingerWag is designed to process filtering locally on your device.
