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:
- Strictly necessary: To authenticate you, protect against cross-site attacks, and remember your locale preference. Without these cookies the Service cannot function.
- Performance and analytics: To understand how users interact with D Line so we can improve reliability and features. These cookies collect data in aggregate or pseudonymous form.
- Third-party services: Embedded services such as payment processing and error reporting set their own cookies. We do not control those cookies directly, but we describe them below.
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 |
| dline_consent | Remembers your cookie banner choice (Accept or Reject) | Persistent (180 days) | Secure, 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
On d-line.app we use Google Analytics 4 with Google Consent Mode v2. When you allow analytics cookies (see section 7), it sets the following cookies:
| Cookie name | Purpose | Duration |
|---|---|---|
| _ga | Distinguishes unique users via a randomly generated ID | 2 years |
| _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 set only when Google Ads conversion measurement is enabled and advertising storage is allowed (see section 7). Google Ads remarketing and ad personalization stay off unless you choose Accept in the cookie banner.
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:
- Chrome: Settings → Privacy and security → Cookies and other site data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Safari: Preferences → Privacy → Manage Website Data
- Edge: Settings → Cookies and site permissions → Cookies and site data
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. Cookie Consent (EEA, UK, Switzerland)
For visitors from the European Economic Area, the United Kingdom, or Switzerland, the EU ePrivacy Directive, the UK Privacy and Electronic Communications Regulations (PECR), and Swiss law require your consent before we set non-essential cookies.
On d-line.app, Google Analytics runs in Google Consent Mode v2. For visitors in those regions, analytics and advertising storage is denied by default. A cookie banner offers Accept and Reject with equal weight. Until you choose Accept, only the strictly necessary cookies in section 3 are set; Google may receive cookieless pings (for example the page address with personal details removed, and your browser type) that set no cookies and carry no advertising identifiers. If we cannot determine your location, we treat you as a visitor from these regions and show the banner. Elsewhere, analytics cookies are on by default and you can opt out as described below. Everywhere, Google Ads remarketing and ad personalization stay off unless you choose Accept.
Your choice is stored in your browser (a dline_consent cookie, kept for 180 days) and applied on later visits.
Changing your choice or opting out: use the Cookie settings link in the site footer to reopen the banner at any time (or clear the dline_consent cookie), enable Global Privacy Control (section 8), or use the Google Analytics opt-out add-on (section 6.2). We never send your name, email address, phone number, or account IDs to Google Analytics.
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 [email protected] with the subject line "Do Not Sell or Share My Personal Information."

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.
