Documents and extracted data stay on your infrastructure: the batch folders of the configuration and, in Enterprise, the SQL Server database. ChronoScan does not host them. Only license data, consumption, technical errors and, if you enable it, anonymous usage telemetry go to the ChronoScan HUB; never document content. AI and cloud OCR send the document text or images to the provider you choose; with Azure OpenAI or local models you control where. See Where things live (folders and files) for the folders.
Credentials
Integration credentials (databases, SharePoint, M-Files, e-mail, AI keys) are stored encrypted, never in clear text: in Config.xml, in the .udl files of DataConnections, and in the MFilesConn, SharePointConn and OAuth folders of the configuration.
The encryption is tied to the Windows machine and user that saved them (Windows DPAPI). A configuration restored on another computer, or used by another Windows account or service account, cannot decrypt them: enter the credentials again on the new machine. Keep this in mind for backups, migrations and Enterprise services running under a service account.
OAuth 2.0 is used for Microsoft 365 and Google instead of mailbox passwords.
Web client passwords (Enterprise) are hashed with salted PBKDF2, with an optional second factor by e-mail or TOTP app.
Support and diagnostics
The Help and Support button builds a support package (logs and sanitised configuration, without credentials, plus optional batches) as a local zip that you review and send yourself. Crash dumps sent to the HUB contain program state, not documents. Telemetry is opt-in and anonymous.
Retention and compliance
You decide how long batches are kept after export; deletion can be automated with a scheduled task or a script. In Enterprise there is traceability of who validated and exported each document, and roles and permissions per job and action. For demanding customers ChronoScan recommends Azure OpenAI in an EU region or local models; the business terms of OpenAI and Google exclude using API data for training.
