Acceptable Use Policy | D-Card

Effective date: 2026-08-18 Last updated: 2026-08-18 This Acceptable Use Policy ("AUP") applies to everyone who accesses D-Card services operated by D-Card, including mobile apps, https://d-card.io, public cards, APIs, and Admin tools (where authorized). Violations may result in content removal, feature limits, suspension, termination, and reports to authorities where appropriate.

1. Purpose

D-Card is a professional digital identity and networking platform. This AUP protects users, recipients of shared cards, our infrastructure, and the public from abuse — without turning the platform into a subjective content-moderation forum for ordinary business disagreements.

2. Prohibited Activities

You may not use the Service to:

Unlawful and fraudulent activity

Engage in unlawful activity of any kind
Commit fraud, identity theft, or financial misrepresentation
Impersonate another person, brand, or organization
Publish phishing content or social-engineering lures

Security abuse

Distribute malware, ransomware, spyware, or malicious files
Attempt to gain unauthorized access to accounts, systems, or data
Probe, scan, or attack the Service except through authorized security reporting to security@d-card.io
Bypass authentication, rate limits, entitlements, or access controls
Interfere with the normal operation of the Service

Spam and automation abuse

Send spam or unsolicited bulk communications through the Service
Perform abusive automated scraping of public cards or APIs
Generate excessive automated requests that degrade availability

Content and IP abuse

Intentionally publish misleading business or profile information designed to deceive recipients

Privacy abuse

Collect, store, or disclose other users' information without a lawful basis
Publish sensitive personal data of third parties on a public card without rights and necessity

3. Public Cards and Professional Context

Because public QR codes and links can be viewed without an account, you must treat public fields as public. Do not place secrets, passwords, payment card numbers, government ID numbers, or others' private data on a public card.

4. Reporting Abuse Report

AUP concerns to support@d-card.io. Security vulnerabilities should go to security@d-card.io. Legal notices may be sent to legal@d-card.io.

5. Enforcement

We may investigate suspected violations and take action we reasonably consider appropriate, including warnings, content removal, suspension, or termination. Enforcement is not a guarantee of monitoring all content in advance.

6. Relationship to Other Policies This

AUP is part of your agreement with us together with the Terms of Service, Content Guidelines, and Privacy Policy.
