Last updated: April 2026  ·  Effective date: April 2026

The Service

Zero Day Digest ("the Service") is a cybersecurity intelligence newsletter platform operated by Modulus Cybersecurity ("we", "us", "our"). The Service provides curated vulnerability intelligence, cybersecurity news, and threat alerts aggregated from publicly available sources, delivered via email and accessible via a web portal at zerodaydigest.io.

Eligibility

By using the Service you confirm that:

• You are at least 18 years of age
• You have the authority to enter into a binding agreement
• Your use of the Service complies with all applicable laws and regulations in your jurisdiction

Subscriptions and Billing

Access to the full Service requires a paid subscription at the rate of $15.00 USD per month.

• Subscriptions are billed monthly in advance and renew automatically
• Payment is processed by Stripe. By subscribing you authorise us to charge your nominated payment method on a recurring monthly basis
• You may cancel your subscription at any time from your account portal. Cancellation takes effect at the end of the current billing period — you retain access until that date
• We do not offer refunds for partial billing periods unless required by applicable law
• We reserve the right to change pricing with 30 days' notice to existing subscribers. Continued use after the notice period constitutes acceptance of the new price

Free Access

We provide limited free access to a subset of content (up to 15 headlines per day across all categories) without requiring a subscription. Free access does not include full article content, filtering, search, email delivery, or the archive. We reserve the right to modify or discontinue free access at any time.

Acceptable Use

You agree to use the Service only for lawful purposes and in accordance with these terms. You must not:

• Share, resell, or redistribute content from the Service without our written permission
• Use automated tools, scrapers, or bots to access or extract content from the Service
• Attempt to gain unauthorised access to any part of the Service or its underlying infrastructure
• Use the Service to harass, threaten, or harm others
• Impersonate any person or entity or misrepresent your affiliation with any person or entity
• Interfere with or disrupt the integrity or performance of the Service
• Use the Service in any manner that could infringe the intellectual property rights of others

Content and Accuracy

We make reasonable efforts to ensure the accuracy and timeliness of information, however:

• We do not warrant that content is complete, accurate, up-to-date, or free from errors
• We are not responsible for decisions made based on content delivered through the Service
• Vulnerability severity ratings, CVSS scores, and remediation guidance are provided as general information and may not apply to your specific environment
• Content is sourced from third parties and we do not endorse, verify, or take responsibility for third-party content

Intellectual Property

All original content, design, code, and materials forming part of the Zero Day Digest platform are the intellectual property of Modulus Cybersecurity and are protected by applicable copyright and intellectual property laws.

Third-party content (news articles, CVE data, advisories) remains the property of the respective rights holders. We aggregate and summarise such content under fair use principles for informational purposes.

Your subscription grants you a personal, non-transferable, non-exclusive licence to access and use the Service for your own internal purposes. You may not reproduce, distribute, or create derivative works from Service content without our written consent.

Account Security

You are responsible for maintaining the confidentiality of your account credentials. You agree to:

• Use a strong, unique password for your account
• Notify us immediately at hello@zerodaydigest.net if you suspect unauthorised access to your account
• Not share your account credentials with others

We are not liable for any loss or damage arising from your failure to maintain account security.

Limitation of Liability

To the fullest extent permitted by applicable law:

• The Service is provided "as is" and "as available" without warranties of any kind, express or implied
• We do not warrant that the Service will be uninterrupted, error-free, or free from viruses or harmful components
• Our total liability to you for any claim arising from your use of the Service shall not exceed the amount you paid us in the 12 months preceding the claim
• We shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, revenue, or profits

Indemnification

You agree to indemnify and hold harmless Modulus Cybersecurity and its officers, directors, employees, and agents from any claims, damages, losses, or expenses (including legal fees) arising from your use of the Service, your violation of these terms, or your violation of any third-party rights.

Termination

We reserve the right to suspend or terminate your account at any time if we reasonably believe you have violated these terms. In the event of termination for cause, you will not be entitled to a refund of any prepaid subscription fees.

You may terminate your account at any time by cancelling your subscription via your account portal and contacting us to request account deletion.

Service Availability

We aim to maintain high availability of the Service but do not guarantee uninterrupted access. We may perform scheduled or emergency maintenance at any time. We will endeavour to provide advance notice of planned downtime where practical.

Governing Law

These terms are governed by the laws of New Zealand. Any disputes arising from these terms or your use of the Service shall be subject to the exclusive jurisdiction of the courts of New Zealand.

Changes to These Terms

We may update these terms from time to time. We will notify subscribers of material changes by email at least 14 days before they take effect. Your continued use of the Service after the effective date constitutes acceptance of the updated terms. If you do not agree to the updated terms, you must cancel your subscription before the effective date.
