Does Expo Contacts require disclosure in my privacy policy?

Yes. Expo Contacts accesses sensitive personally identifiable information (PII) protected under GDPR, CCPA, and similar privacy laws. You must disclose this access in your privacy policy, explain the business purpose, and document explicit user consent before any contact data is collected. Apple and Google also require clear usage descriptions in app store listings.

What specific data does Expo Contacts collect from my device?

Expo Contacts collects contact names, phone numbers, email addresses, and contact photos stored on the user's device. This data is only accessed when the user grants permission through the device's permission system. The scope of data collected depends on which contact fields the application requests and the user permits.

Does Expo Contacts use cookies or require a cookie banner?

No. Expo Contacts does not use cookies. However, you must still obtain explicit consent before accessing contact data through other mechanisms, such as permission prompts or consent banners within your app or website, particularly under GDPR.

Who processes Expo Contacts data and where is it stored?

Expo (650 Industries), a United States-based company, operates and processes data through Expo Contacts. Any contact data accessed through this service may be processed in the U.S. You should review data transfer compliance, including adequacy decisions and Standard Contractual Clauses if you operate under GDPR.

When does Expo Contacts trigger privacy obligations?

Installation and Data Access Rights

Adding Expo Contacts to your Expo application immediately creates a pathway to device contact data—including names, phone numbers, email addresses, and contact photos. The moment your app requests permission to access the Contacts API, the data flows start.

Jurisdiction-Specific Triggers

GDPR (EU/EEA users): If your app is accessible to EU residents or you're processing contacts of EU users, Expo Contacts triggers GDPR Article 6 (lawful basis), Article 13/14 (transparency), and Article 32 (security) obligations immediately. Contact data is personal data and qualifies as sensitive under GDPR Article 9. You must have explicit consent before Expo Contacts accesses device contacts—not just app install consent.

Common compliance pitfalls

Pitfall 1: Vague or Missing Permissions Prompt Text

The mistake: Using Apple's default or placeholder NSContactsUsageDescription ("App needs access to contacts") without explaining your specific use case.

Why it happens: Teams assume the OS permission dialog is sufficient. Expo Contacts requires *you* to provide context in your app's permission prompt.

Consequence: App Store rejection (Apple's Human Review flags non-descriptive prompts), user distrust, and inability to launch. Regulators (UK ICO, EDPB) also flag unclear disclosures as violating transparency principles (GDPR Article 13).

Pitfall 2: No Separate Consent Layer for Contact Access

The mistake: Burying Expo Contacts consent inside a generic "permissions" or "location & contacts" toggle, rather than isolating contact consent.

Why it happens: Teams treat OS-level permissions as sufficient consent and don't realize GDPR Article 7 and CCPA require *affirmative, specific* consent for sensitive data.

Consequence: GDPR violations (no granular consent basis), CCPA non-compliance (users can't opt out of contact collection specifically), and enforcement risk from DPAs if audited. Apple may also reject if the bundling obscures the Contacts permission request.

Pitfall 3: Exporting Contacts to Third-Party Services Without Disclosure

The mistake: Using Expo Contacts to sync or upload device contacts to your backend or a CRM (e.g., Mailchimp, HubSpot) without explicitly telling users that Expo (650 Industries, US) and your service provider(s) will access the data.

Why it happens: Teams focus on their own app logic and forget that Expo's SDK and downstream processors are separate data handlers requiring disclosure and DPAs (GDPR Article 28).

Consequence: GDPR Article 5 breach (lack of transparency about who processes data), missing Data Processing Agreements, FTC enforcement risk (under UDAP if using third-party services), and potential CCPA violations if users in California aren't told about third-party sharing.
