Why we built it
Application forms, schools, offices and government services ask for documents as PDFs - often under a size limit and in a particular order. Those documents are personal: ID cards, certificates, bank letters, contracts.
Most online tools handle this by uploading your files to their servers. SentrueFile does the work on your own phone or computer instead, so your documents never have to leave it.
