Website data

Calculation inputs and results are processed client-side. The v1 source does not send them to DueRule, store them on a server, or attach analytics identifiers. Standard hosting infrastructure may process routine request data such as IP address, browser type, requested path, and timestamp for security and delivery.

iOS app data

The planned iOS app stores profiles, saved calculations, and reminders locally on the device. It has no account, backend, CloudKit sync, advertising, or tracking SDK at launch. Apple may process App Store purchases under Apple’s own terms.

Support messages

If you contact support, the operator processes the information you choose to send to answer the request. Do not send confidential deadline content, legal documents, or sensitive matter details.

Changes and contact

This source draft was reviewed August 20, 2026. A final operator contact and public effective date remain launch gates. Material privacy changes require an updated notice before deployment.
