Privacy & Permissions Notice Your privacy is our top priority. DocSearch+ works entirely offline and respects your data boundaries. Why MANAGE_EXTERNAL_STORAGE Permission is Required: To provide complete file-content search, DocSearch+ requires permission to access and index your documents locally across storage. Because the app operates offline, your documents never leave your phone. Without this permission, the core full-text indexing and search functions cannot operate.
