FAQ

How does message filtering work?

When you recive a text message from a number that is not in your contact list, Simply Filter SMS will filter it based on the following rules:

• If a text message contains text matching to a filter from the 'Allowed Texts' it will be delivered regularly.
• If not, the message will be scanned for matching filters from the 'Blocked Texts' and in case any were found it will be delivered to the Junk folder.
• If the text doesn't contain any text that matches the filters, it will be delivered regularly.

Are my messages exposed to the app developer?

No. Simply Filter SMS does not collect any information whatsoever, all message processing is done locally on your device without any logging.

What about iMessages and messages from my contacts?

Apple does not expose those messages to any developer, they remain completely private.

Where are the filtered messages?

When a text message is tagged as junk it will still be available for reading on the Messages app under the Junk folder.

What's the difference between Junk/Transactions/Promotions folders?

Not much, you can filter any word to any folder. Those folders are not customable in any way. Only messages filtered to the Junk folder will be delivered silently.

How does Automatic Filtering work?

Automatic Filtering is using a pre defined list of terms to determine if a message should be sent to the Junk folder or not. The lists are updated periodically with new terms. Your regular filters are still considered when Automatic Filtering is on.
