We do not sell or share personal information for cross-context behavioral advertising. We also honor Global Privacy Control (GPC) signals. When our web services detect a GPC opt-out signal from your browser, we treat it as a "do not sell or share" instruction for that session and any subsequent visits from that browser.

For all other states with active privacy statutes, we extend comparable rights to the extent required by applicable law. To exercise any of these rights, email support@davincitechsolutions.com with your state of residence and specific request.

4. Data Retention

| Data Category | Retention Period | Reason | |---|---|---| | Account information | Duration of contract + 30 days | Service continuity and wind-down | | Call Detail Records | 18 months minimum (FCC); up to 7 years (state/contractual) | U.S. telecom regulatory requirement — jurisdiction-dependent | | Call Recordings | 90 days (configurable by organization) | Storage cost optimization | | Crash/error reports | 30 days | Debugging and security investigation | | Push notification tokens | While device is registered | Incoming call delivery |

Deleted data is purged from our primary databases within 30 days and from backups within 180 days.

Note on CDR retention: The FCC mandates a minimum 18-month retention period for call detail records. State utility commissions and enterprise contracts may require longer retention — up to 7 years in some jurisdictions. We apply the longer period where required.

5. Third-Party Data Processors

We share data with the following processors under Data Processing Agreements (DPA):

5.1 Telecommunications Carriers

5.2 Cloud Infrastructure

5.3 Push Notification Services

5.4 Payment Processing

5.5 Error Reporting

5.6 AI Features (conditional)

6. Call Recording Disclosure

Recording is off by default and must be explicitly enabled by your organization's administrator.

When recording is enabled:

Multi-party consent requirements: Calls that touch the following U.S. states require the consent of all parties to the call before recording (all-party or two-party consent states): California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, New Hampshire, Pennsylvania, and Washington. Equivalent requirements exist in EU member states and other jurisdictions.

Customer responsibility: The customer (tenant administrator) is responsible for obtaining all legally required consents before enabling recording. D Line surfaces disclosure UI but does not independently verify that consent has been obtained. We accept no liability for a tenant's failure to comply with applicable recording laws.

7. Encryption and Security

7.1 In Transit

7.2 At Rest

7.3 Security Measures

Limitation: Real-time media is encrypted end-to-end when both parties support SRTP. The SIP signaling server temporarily processes call metadata in plaintext to route calls. We do not store plaintext call content.

8. Children and Young People

United States: D Line is not directed to individuals under 18 years of age. We do not knowingly collect personal data from persons under 18.

European Union and United Kingdom: In accordance with GDPR and the UK Age Appropriate Design Code, we do not knowingly process personal data of children under 16 without parental or guardian consent.

If we become aware that a minor has provided personal information, we will delete it promptly. Parents or guardians concerned about data collection should contact support@davincitechsolutions.com.
