Website has no registration/login. All the work is done without it. User comes, uploads paper, pays for it and receives reports. Url: [login to view URL] Uploading paper: User can upload: docx, google docs. Payment: only one payment gateway – checkout card payment. Service: User uploads paper, it is stored for 300 seconds. User is asked to pay for check. Appears new window/dialog box/popup where user is informed that he must pay and the report will be sent by email. He is asked to provide email. After clicking next, he is redirected to checkout, where he enters card data and pakes payment. Once payment is made, the uploaded document is proceeded. Report: When paper is checked and report is created, unique url where report is availble, is created. The report is active for 2 days or when user clicks “delete report”. The clock is working backwards saying “We care about data protection very serious – your data will be erased in XX minutes”. User also can generate pdf file-report. Questions: 1. how to check google docx (not files, but texts people write in google docs)? 2. is it possible to create pdf with links? that’s for report we would create for users. ADDITIONAL WORK: languages versions add to [login to view URL]
