# SDK Privacy Methods Chartboost requires that publishers obtain consent from their users to be able to process personal data and provide relevant ads. Review our [COPPA FAQs](/en/faq/coppa/) for more information on behavior targeting. ## GDPR To set GDPR consent:

/**
* GDPR support settings:
* nonbehavioral means the user does not consent to targeting (Contextual ads)
* behavioral means the user consents (Behavioral and Contextual Ads)
*/
Chartboost.addDataUseConsent(CHBDataUseConsent.GDPR(CHBDataUseConsent.GDPR.Consent.behavioral))

/**
* GDPR support settings:
* CHBGDPRConsentNonBehavioral means the user does not consent to targeting (Contextual ads)
* CHBGDPRConsentBehavioral means the user consents (Behavioral and Contextual Ads)
*/
[Chartboost addDataUseConsent:[CHBGDPRDataUseConsent gdprConsent:CHBGDPRConsentBehavioral]];

Possible consent values are `CHBGDPRConsentBehavioral` and `CHBGDPRConsentNonBehavioral.` Chartboost will store the consent status even after the app is closed. In order to reset this information use:

Chartboost.clearDataUseConsent(for: CHBPrivacyStandard.GDPR)

[Chartboost clearDataUseConsentForPrivacyStandard:CHBPrivacyStandardGDPR];

## CCPA To set CCPA consent:

/**
* CCPA support settings:
* optInSale(1YN-) means the user consents (Behavioral and Contextual Ads)
* optOutSale(1YY-) means the user does not consent to targeting (Contextual ads)
*/
Chartboost.addDataUseConsent(CHBDataUseConsent.CCPA(CHBDataUseConsent.CCPA.Consent.optInSale))

/**
* CCPA support settings:
* CHBCCPAConsentOptInSale(1YN-) means the user consents (Behavioral and Contextual Ads)
* OPT_OUT_SALE(1YY-) means the user does not consent to targeting (Contextual ads)
*/
[Chartboost addDataUseConsent:[CHBCCPADataUseConsent ccpaConsent:CHBCCPAConsentOptInSale]];

Possible consent values are `CHBCCPAConsentOptInSale` and `CHBCCPAConsentOptOutSale`. Chartboost will store the consent status even after the app is closed. In order to reset this information use:

Chartboost.clearDataUseConsent(for: CHBPrivacyStandard.CCPA)

[Chartboost clearDataUseConsentForPrivacyStandard:CHBPrivacyStandardCCPA];

## COPPA To set COPPA consent:

/**
* COPPA:
* true means that COPPA restrictions apply and the iOS advertising identifier (IDFA) is not transmitted. (Contextual ads)
* false means that COPPA restrictions do not apply. (Behavioral and Contextual Ads)
*/
Chartboost.addDataUseConsent(CHBDataUseConsent.COPPA(isChildDirected: true))

/**
* COPPA:
* true means that COPPA restrictions apply and the iOS advertising identifier (IDFA) is not transmitted. (Contextual ads)
* false means that COPPA restrictions do not apply. (Behavioral and Contextual Ads)
*/
[Chartboost addDataUseConsent:[CHBCOPPADataUseConsent isChildDirected:true]];

Possible consent values are `true` and `false`. Chartboost will store the consent status even after the app is closed. In order to reset this information use:

Chartboost.clearDataUseConsent(for: CHBPrivacyStandard.COPPA)

[Chartboost clearDataUseConsentForPrivacyStandard:CHBPrivacyStandardCOPPA];

## LGPD To set LGPD consent:

/**
* LGPD:
* true means that the user consents (Behavioral and Contextual Ads)
* false means that the user does not consent to targeting (Contextual Ads)
*/
Chartboost.addDataUseConsent(CHBDataUseConsent.LGPD(allowBehavioralTargeting: true))

/**
* LGPD:
* true means that the user consents (Behavioral and Contextual Ads)
* false means that the user does not consent to targeting (Contextual Ads)
*/
[Chartboost addDataUseConsent:[CHBLGPDDataUseConsent allowBehavioralTargeting:true]];

Possible consent values are `true` and `false`. Chartboost will store the consent status even after the app is closed. In order to reset this information use:

Chartboost.clearDataUseConsent(for: CHBPrivacyStandard.LGPD)

[Chartboost clearDataUseConsentForPrivacyStandard:CHBPrivacyStandardLGPD];

## Custom Consent Chartboost allows publishers to provide custom consent information, besides the predefined GDPR and CCPA values. For example:

Chartboost.addDataUseConsent(CHBDataUseConsent.Custom(privacyStandard: CHBPrivacyStandard.CCPA, consent: "1NN-"))

[Chartboost addDataUseConsent:[CHBCustomDataUseConsent customConsentWithPrivacyStandard:CHBPrivacyStandardCCPA consent:@"1NN-"]];

Caution: Currently, the only custom consent values allowed are valid IAB's U.S. Privacy String for the CHBPrivacyStandardCCPA standard.

## Reading Consent Status Use `dataUseConsent(for:)` to read the current consent for any privacy standard. This returns the same `CHBDataUseConsent` subclass that was passed to `addDataUseConsent(_:)`, or `nil` if no consent has been set.

// Check if GDPR consent has been set
if let gdpr = Chartboost.dataUseConsent(for: .GDPR) as? CHBDataUseConsent.GDPR {
    if gdpr.consent == .nonBehavioral {
        // User has not consented to behavioral targeting
    }
}

// Check if COPPA restrictions apply
if let coppa = Chartboost.dataUseConsent(for: .COPPA) as? CHBDataUseConsent.COPPA {
    if coppa.isChildDirected {
        // COPPA restrictions apply
    }
}

// Check if GDPR consent has been set
CHBGDPRDataUseConsent *gdpr = [Chartboost dataUseConsentForPrivacyStandard:CHBPrivacyStandardGDPR];
if (gdpr && gdpr.consent == CHBGDPRConsentNonBehavioral) {
    // User has not consented to behavioral targeting
}

// Check if COPPA restrictions apply
CHBCOPPADataUseConsent *coppa = [Chartboost dataUseConsentForPrivacyStandard:CHBPrivacyStandardCOPPA];
if (coppa && coppa.isChildDirected) {
    // COPPA restrictions apply
}
