Compliances to Watch out for

App compliance is necessary to be adhered to for any mobile application launched in the U.S, particularly if you aim at regulated industries or manage user data. Let’s take a look at the core U.S. app development compliances you should take care of:

GDPR (General Data Protection Regulation)

Although an EU-based law, it also applies to US-based apps that manage the data of EU citizens. It ensures the right to access, user-specific data consent, and data deletion features. 

CCPA/CCRA ( California Consumer Privacy Act/ California Privacy Rights Act)

This data privacy law is creating a new standard for every U.S. business. Your application must enable users to opt out of data selling, view the data collected, and request its deletion.

HIPAA (Health Insurance Portability & Accountability Act)

Necessary for healthcare applications that manage Protected Health Information (PHI). It follows secure transmission, data encryption, and user authorization controls for compliance.

COPPA (Children’s Online Privacy Protection Act)

If your application targets or gathers information from users under the age of 13, you must obtain verifiable parental consent and minimize data collection.

ADA (Americans with Disabilities Act)

Applications should be accessible to all users, including users with disabilities. Adhering to Web Content Accessibility Guidelines helps meet ADA compliance.

PCI-DSS (Payment Card Industry Data Security Standard)

For apps that handle payments, the standard includes ensuring tokenization, secure card processing, SSL encryption, and eliminating fraud for the security of customer transactions.

FTC (Federal Trade Commission) Guidelines

The standard involves clear policies for data usage, truthful advertising, and implementing transparent permissions; violations can result in huge fines or removal from app stores.

State-Level Data Privacy Laws

States such as Colorado, Virginia, and Utah have their own privacy regulations. Apps operating nationwide must adopt a centralized privacy compliance framework to ensure security.

App Store & Play Store Compliance

Both stores have stringent policies for data collection, subscription billing, AI transparency, and user consent. Ensure your app aligns with the modern developer guidelines before submission.
