Cookie Policy

Effective Date: June 5, 2026

Davinci Tech Solutions ("we," "us," "our," or "Company") operates D Line, a cloud-based VoIP softphone application (the "Service"). This Cookie Policy explains what cookies are, which cookies we set, and how you can control them.

1. What Are Cookies

Cookies are small text files placed on your device by a website or web application when you visit. They allow the site to remember information about your visit — such as your login session or language preference — so you do not have to re-enter it each time.

Cookies are not programs and cannot execute code or transmit viruses. They may be set by us ("first-party cookies") or by third-party services embedded in our pages ("third-party cookies"). Cookies persist for different lengths of time: session cookies expire when you close your browser, while persistent cookies remain until they expire or you delete them.

2. How We Use Cookies

We use cookies for three broad purposes:

We do not use cookies for cross-site behavioral advertising. We do not sell cookie-derived data to third parties.

3. Strictly Necessary Cookies

These cookies are essential for the Service to operate. They cannot be disabled without breaking core functionality such as login and security.

| Cookie name | Purpose | Type | Attributes | |---|---|---|---| | auth_token | Authenticates your session after login | Session / Persistent | HttpOnly, Secure, SameSite=Lax | | XSRF-TOKEN | CSRF protection — validated with every mutating request | Session | Secure, SameSite=Strict | | Laravel session cookie (name varies, e.g. davinci_session) | Ties server-side session data to your browser | Session | HttpOnly, Secure, SameSite=Lax | | NEXT_LOCALE | Stores your language preference (en, ru, uz, es) so it persists across pages | Persistent (1 year) | SameSite=Lax |

Important: Disabling or deleting these cookies will prevent you from logging in and will break the D Line web portal. They do not track you across unrelated websites.

4. Analytics Cookies

4.1 Google Analytics

If the environment variable NEXT_PUBLIC_GA_MEASUREMENT_ID is configured for your deployment, Google Analytics is active and sets the following cookies:

| Cookie name | Purpose | Duration | |---|---|---| | _ga | Distinguishes unique users via a randomly generated ID | 2 years | | _gid | Distinguishes users within a 24-hour session | 24 hours | | _ga_<MEASUREMENT_ID> | Stores session state for GA4 | 2 years |

Data collected includes page views, session duration, and feature usage in aggregate. IP addresses are anonymized before storage. Google Analytics data is transmitted to Google LLC (USA). Google's privacy policy is at policies.google.com/privacy.

4.2 Google Ads

If Google Ads conversion tracking is enabled for a deployment, the following cookies may be present:

| Cookie name | Purpose | Duration | |---|---|---| | _gcl_au | Stores and tracks conversions from Google Ads | 90 days | | _gcl_aw | Links ad clicks to conversion events | 90 days |

These cookies are only set when you arrive via a Google Ads link. They do not track you on unrelated websites beyond what Google's own policies permit.

5. Third-Party Cookies

5.1 Stripe

If payment or billing widgets are loaded inline (for example, on the billing settings page), Stripe may set cookies for fraud detection and session continuity. Stripe is a PCI-DSS Level 1 certified processor. Its cookie policy is at stripe.com/privacy.

5.2 Sentry

Sentry error-reporting may set a short-lived session correlation cookie to link a browser session to a captured error report. This cookie contains no personally identifiable information. Sentry's privacy policy is at sentry.io/privacy.

6. How to Manage Cookies

6.1 Browser Controls

All major browsers allow you to view, block, or delete cookies via their settings menus:

Blocking all cookies will prevent you from logging in to D Line because the strictly necessary cookies (section 3) are required for authentication. We recommend allowing cookies from davincitechsolutions.com while blocking third-party cookies if you want to limit tracking.

6.2 Opt-Out of Google Analytics

You can opt out of Google Analytics across all sites by installing the Google Analytics Opt-out Browser Add-on. You can also opt out of Google Ads personalization at adssettings.google.com.

6.3 Do Not Track

We do not currently respond to the legacy "Do Not Track" (DNT) browser header because there is no agreed standard for how sites should honor it. We do, however, honor the Global Privacy Control signal — see section 8 below.

7. EU/UK Opt-In (Cookie Consent)

For visitors from the European Union or the United Kingdom, we are required by the EU ePrivacy Directive and the UK Privacy and Electronic Communications Regulations (PECR) to obtain your explicit consent before setting non-essential cookies.

When accessing D Line from an EU or UK IP address, a cookie consent banner will be displayed before any analytics or advertising cookies are loaded. You may accept all cookies, accept only strictly necessary cookies, or configure your preferences individually. Your consent choice is stored and respected on subsequent visits.

Until you have given consent, only the strictly necessary cookies listed in section 3 are set. Analytics and advertising cookies in sections 4 and 5 are not loaded until consent is granted.

Note: The full cookie consent management interface (banner and preference center) is planned for a near-term release. Until it is live, EU/UK visitors who wish to opt out of analytics cookies should use the browser controls described in section 6 or the Google Analytics opt-out add-on.

8. California "Do Not Sell or Share" and Global Privacy Control

We do not sell personal information derived from cookies to third parties, and we do not share such information for cross-context behavioral advertising purposes.

We honor the Global Privacy Control (GPC) signal. When our web services detect a valid GPC opt-out signal from your browser, we treat it as a "do not sell or share" instruction and suppress analytics and advertising cookies for that session and any subsequent visits from that browser. No additional action is required from you if GPC is enabled in your browser.

California residents may also submit a manual opt-out request by emailing support@davincitechsolutions.com with the subject line "Do Not Sell or Share My Personal Information."

9. Contact

If you have questions about our use of cookies or wish to exercise your privacy rights:

Davinci Tech Solutions Email: support@davincitechsolutions.com

For EU residents: You may lodge a complaint with your national data protection authority. For California residents: You may contact the California Attorney General at oag.ca.gov.

10. Changes to This Policy

We may update this Cookie Policy to reflect changes in the cookies we use, applicable law, or our business practices. We will notify you of material changes via email or in-app notification at least 10 days before the change takes effect. The "Last Updated" date at the bottom of this page indicates when the most recent revision was made. Your continued use of D Line after the effective date constitutes acceptance of the updated policy.
