SumDoc opens and edits Word documents on your device. The editor runs on the same native DOCX engine that powers SumOffice on the desktop and on the server β so a document looks and behaves the same wherever you open it. No re-rendering, no drift between what you see on the phone and what your colleague sees on a laptop. WHAT IT DOES β’ Opens .docx and .docm files β from the Files app, mail, or any appβs βOpen inβ¦β β’ Edits text, applies styles and formatting with the familiar ribbon β’ Edits pictures: wrap, crop, borders and effects β’ Keeps the document structure intact β tables, lists, page layout β’ Built-in assistant: ask how to do something and get the steps, in your language β’ Report a problem in two taps β your report gets a number and a status right in the app YOUR FILES STAY YOURS Editing happens on the device. Documents are not uploaded anywhere, and the app does not require an account to open a file. Only what you send to support leaves the phone β see the privacy policy. PART OF SUMOFFICE SumOffice is an office suite built around one document engine: the same logic in a desktop application, inside your own product, on a server, and here on the phone. SumSheet is its spreadsheet counterpart. SumOffice is an independent product and is not affiliated with Microsoft. Learn more: https://sumoffice.com
