Privacy Policy for Riragon Prime Generator
Last updated: September 21, 2026

Riragon Prime Generator is published by riragon. This policy explains how information is handled by the Windows application, its command-line interface, JSON API, and optional Model Context Protocol (MCP) integration.

Information processed on your device

The application generates and verifies prime-number datasets on your device. It processes generation settings, selected file and folder paths, application preferences, and files used for generation, verification, settings import, and export. It stores job records, timestamps, progress, errors, verification results, and reports to support its features, including history and resuming interrupted work. It also reads available memory, processor capacity, and free disk space to plan calculations.

File and folder paths may contain your Windows username, a person's name, or other identifying information. Such paths may appear in saved settings, job records, reports, copied commands, and integration responses. Prime numbers themselves do not identify you, but the files and records associated with them may contain these paths.

Storage and automatic data collection

Application settings and job records are stored in Windows user-data folders. Generated datasets, reports, and exported settings are saved to the locations you choose. The application does not require a riragon account and does not include advertising, usage analytics, or automatic uploads of your files, job records, or crash reports to riragon. We do not sell personal information or use it for targeted advertising.

Optional integrations and sharing

The JSON API and MCP integration exchange requests and responses with a client you choose, using local standard input and output. Responses can include calculation settings, file paths, job status, errors, and results. If you connect a client that uses an online AI service or another external service, that client may send this information to its provider under its own settings and privacy policy. You control whether to configure and use these integrations and can stop the connection or remove the configuration.

Saving files to a network or cloud-synchronized folder, copying information to the clipboard, sharing reports, or opening external links may cause information to be handled by the services you use. Those services' privacy policies apply to their processing. The application does not independently upload this information to a service operated by riragon.

Your choices and data retention

You choose the output location and can inspect, move, or delete generated files. Automatic saving of calculation and desktop settings can be disabled. The language preference and auto-save choice remain saved, and job records are still created to support processing and recovery.

Local records have no automatic expiry. Clear history hides entries from the history view; it does not delete the underlying job records or generated files. To remove stored application information, close the application and its CLI/MCP processes, then delete the relevant application data and output files using Windows. Removing job records or incomplete datasets may prevent resuming interrupted work. Contact us if you need help locating these files.

Data protection

Local files are subject to Windows account permissions and the protections of the storage locations you select. The application does not add its own encryption to settings, job records, reports, or generated files. Access by other users, applications, backup tools, or synchronization services depends on your device and storage settings. Review reports and copied commands before sharing them if their paths contain identifying information.

Support communications

If you contact us, we receive the email address, message, and any attachments you choose to send. We use this information to respond, investigate the reported issue, and meet applicable legal obligations. Correspondence is processed through the email services used by you and us. We retain it only for as long as needed for these purposes and may disclose it when legally required. You may contact us to request access to, correction of, or deletion of personal information in support correspondence, subject to applicable law. We cannot remotely access or delete files stored only on your device.

Microsoft and other services

Microsoft separately handles Microsoft Store transactions, licensing, updates, and Windows services under its own privacy statement. The application does not receive your payment card details. Microsoft services and any third-party clients or websites are governed by their respective privacy policies.

Changes and contact

We will update this policy when the application's data practices change and revise the date above. For privacy questions or requests, contact riragon at info@riragon.com
