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 app’s β€œOpen in…” 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.
