What is Deadline Shield?

Deadline Shield is an AI-assisted document deadline extraction, tracking, and reminder application from Duo Dynamics IT Ltd. It helps users review dates in paperwork and save approved dates as reminders.

How it works

Upload a PDF, photo, or Word file, or enter a deadline manually.
Review suggested renewals, expirations, notice periods, and other obligations alongside available source evidence.
Confirm the dates you want to track. Findings do not become reminders without your approval.
Track saved deadlines and receive email reminders; optional push notifications are also available.

For everyday business paperwork

Common use cases include contract renewals and cancellation notice windows, business licenses, permits, insurance expirations, certifications, registrations, and property-management paperwork. Explore the use cases and existing deadline guides.

Start with a limited free preview

Yes. The limited document preview requires no account or credit card. It checks selected likely-relevant sections rather than providing an exhaustive document review. The private original is available for up to 30 minutes to move into an account before it expires. See the Deadline Health Check. Ongoing tracking requires a paid plan; compare pricing and limits.

Private by default, with human review

No. Originals are stored in private Cloudflare R2 storage. Authenticated document routes check workspace ownership. The limited free preview uses a high-entropy scan token. Public crawlers are permitted to read product information, not private documents or account APIs. Read the Security Center and Privacy Policy.

What it does not promise

No. It is an assistive organizational tool, does not guarantee that every deadline is found, and does not provide legal, tax, accounting, insurance, regulatory, or other professional advice.
