The Cloud subscription is limited to the number of processed words during a year, no matter their correctness level. The number of words depends on the Cloud plan. For example, the Basic/Starter package includes up to 200 million words processed per year. The services calculate the total number of words which were processed, no matter their correctness level.

In such products as WProofreader or SCAYT, the text will be divided into sentences and sent in batches (up to 10 sentences) for checking. Once a user starts editing a document with the proofreader enabled, the whole text will be parsed and divided into sentences. All the words in the text will be counted excluding punctuation and spaces. The words will be counted again if there are changes in the sentences. 

Separately, there is a mechanism of sentence caching during the session. If you are entering the same sentence again and again, or the same paragraph, no external calls will be made. Thus, those words won't be counted.

For example, you have a text for 1,000 words. Then you add a word to complete a sentence. In this case, this sentence will be rechecked. The total number of counted words will be 1,000 + the length of a sentence.

Another example, if you are editing the document with 1,000 words, then save the document and reload the page. After that, you start editing the same document again, all 1,000 words will be checked again. Thus, the total will be 2,000.
