Introduction

This Cookie Policy explains how SIPSTACK Inc. ("SIPSTACK", "we", "us", or "our") uses cookies and similar technologies on our website at sipstack.com (the "Site").

What Are Cookies?

Cookies are small text files that are stored on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.

Types of Cookies

Session Cookies: Temporary cookies that expire when you close your browser.

Persistent Cookies: Cookies that remain on your device for a set period or until you delete them.

First-Party Cookies: Set by the website you're visiting.

Third-Party Cookies: Set by a domain other than the one you're visiting.

Cookies We Use

Strictly Necessary Cookies

These cookies and services are essential for the operation of our Site. They record your consent choice, protect our forms from bots, and attribute referrals. They do not require your consent.

| Cookie / Service | Purpose | Duration | Type | |-------------|---------|----------|------| | ss_cc | Stores your cookie consent record: the policy version you answered, the date and time of your choice, the categories you accepted, and whether a Global Privacy Control signal was honoured | 365 days | First-party | | ref | Stores a referral code, set only after our servers have confirmed the code is valid when you open a referral link (/r/). Shared with switchboard.sipstack.com so a signup is credited to the referrer | 12 months (the partner attribution window) | First-party (.sipstack.com) | | ref_type | Records whether that validated referral code belongs to a partner or a customer, so we show the right offer | 12 months | First-party (.sipstack.com) | | Cloudflare Turnstile | Bot protection on our contact, demo, booking, newsletter and partner forms. Cloudflare may set or read its own cookies and challenge data on challenges.cloudflare.com while the check runs | Session | Third-party (Cloudflare) | | Cloudflare Web Analytics | Cookieless page-load measurement added by our CDN (Cloudflare) at the network edge. It sets no cookies and does not store data on your device | None (no cookie) | Third-party (Cloudflare) |

Can you opt out? No. These are strictly necessary for the Site to function, to keep our forms free of abuse, and to honour our referral agreements.

Analytics & Performance Cookies

These cookies help us understand how visitors use our website. They are set only after you accept the Analytics & Performance category. If you submit a form while they are on, we link your visits to the name, email and company you provide.

| Cookie Name | Purpose | Duration | Provider | |-------------|---------|----------|----------| | _ga | Distinguishes unique users | 13 months | Google Analytics | | _ga_* | Stores session state | 13 months | Google Analytics | | ph_* | Product analytics, session replay, and exception capture | 1 year | PostHog (PostHog Cloud, US region) |

Can you opt out? Yes. You can turn this category off at any time in the cookie preferences manager. When you do, we stop PostHog, remove Google Analytics, and delete these cookies.

Marketing & Advertising Cookies

These cookies are set only after you accept the Marketing & Advertising category. With that consent, we share identifiers and browsing events from this Site with Meta, LinkedIn and Microsoft (Bing) so we can measure and retarget our advertising. Under some US state privacy laws this may be a "sale" or "sharing" of personal information. If your browser sends a Global Privacy Control signal, this category stays off.

| Cookie Name | Purpose | Duration | Provider | |-------------|---------|----------|----------| | _fbp | Identifies your browser for Meta advertising and measurement | 90 days | Meta (Facebook) | | fr | Delivers, measures, and improves ad relevance (set on facebook.com) | 90 days | Meta (Facebook) | | li_* (e.g. li_sugr, li_gc) | Identifies your browser for LinkedIn conversion tracking and retargeting | Up to 6 months | LinkedIn | | bcookie | Browser identifier (set on linkedin.com) | 1 year | LinkedIn | | bscookie | Secure browser identifier (set on linkedin.com) | 1 year | LinkedIn | | lidc | Routing / data-center selection (set on linkedin.com) | 24 hours | LinkedIn | | UserMatchHistory | LinkedIn Ads ID syncing (set on linkedin.com) | 30 days | LinkedIn | | AnalyticsSyncHistory | Records when the browser was last synced with LinkedIn (set on linkedin.com) | 30 days | LinkedIn | | MUID | Identifies unique browsers across Microsoft properties | 13 months | Microsoft Advertising (Bing) | | MR | Refreshes the MUID identifier (set on bing.com) | 7 days | Microsoft Advertising (Bing) | | _uetsid | Stores a session identifier for Microsoft Advertising | 1 day | Microsoft Advertising (Bing) | | _uetvid | Identifies unique visitors for conversion tracking | 13 months | Microsoft Advertising (Bing) |

Cookies set on facebook.com, linkedin.com or bing.com belong to those companies; we cannot read or delete them. Withdrawing consent stops our Site from loading their tags, and we delete the cookies and stored identifiers set on our own domain.

Can you opt out? Yes. Use Your Privacy Choices in the footer, or send a Global Privacy Control signal from your browser.

Preference Cookies

We do not currently set any preference cookies. If we add them (for example for a theme or language setting), we will list them here and ask for your consent first.

Local Storage and Session Storage

Some features store data in your browser's local storage or session storage instead of cookies. This data stays on your device and is not sent to us automatically.

| Key | Purpose | Duration | Category | |-----|---------|----------|----------| | ph_*, __ph_opt_in_out_* | Product-analytics state and your analytics opt-in / opt-out flag (set by our product-analytics provider, named under Analytics & Performance Cookies above) | Until deleted (removed when you withdraw analytics consent) | Analytics | | _uet* | Microsoft Advertising (Bing) visitor and session identifiers | Until deleted (removed when you withdraw marketing consent) | Marketing | | li_adsId | LinkedIn advertising identifier | Until deleted (removed when you withdraw marketing consent) | Marketing | | lastExternalReferrer* | Meta Pixel record of the last external referring site | Until deleted (removed when you withdraw marketing consent) | Marketing | | app-state | Remembers which site banners you have dismissed | Until deleted | Strictly necessary | | sipstack:pricing-currency | Remembers the pricing currency (USD or CAD) you chose | Until deleted | Strictly necessary | | ss_lead_email (session storage) | Carries the email you just entered into the demo form to the sign-up page, so you do not have to retype it. Removed as soon as that page reads it | Until read, or until the tab closes | Strictly necessary |

To pick your currency automatically, the pricing pages ask our own CDN (Cloudflare) which country your connection comes from. No third-party geolocation service is used, and nothing is stored unless you choose a currency yourself.

How to Manage Cookies

You can manage your cookie preferences at any time by clicking the "Your Privacy Choices" link in the footer of every page of our Site. This will open the preferences panel where you can enable or disable specific cookie categories.

Browser Settings

Most browsers allow you to control cookies through their settings. You can typically:

  • View what cookies are stored
  • Delete all or specific cookies
  • Block all cookies
  • Block third-party cookies
  • Clear cookies when closing the browser

Popular browser cookie settings:

  • 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

Note: Blocking all cookies may prevent certain features of our Site from working properly.

You can also opt out of certain third-party cookies directly:

Third-Party Cookies

Some cookies on our Site are set by third-party services we use:

  • Google Analytics 4: Web analytics to understand visitor behavior
  • PostHog (PostHog Cloud, US region): Product analytics, session replay, and exception capture used to improve site experience and debug issues
  • Meta Pixel: Advertising and conversion tracking
  • LinkedIn Insight Tag: B2B advertising and conversion tracking
  • Microsoft Advertising (Bing UET): Search advertising conversion tracking and retargeting
  • Cloudflare (Turnstile and Web Analytics): Bot protection on our forms, and cookieless page-load measurement by our CDN

These third parties have their own privacy policies and cookie policies. We recommend reviewing them:

Do Not Track and Global Privacy Control

Some browsers send a "Do Not Track" (DNT) signal. Our Site does not respond to DNT, because there is no common standard for it. You can turn tracking off in our cookie preferences manager.

We do honour Global Privacy Control (GPC). If your browser sends a GPC signal, we treat it as a request to opt out of the sale or sharing of your personal information: the Marketing & Advertising category stays off, even if you click "Accept all", and the preferences panel tells you that GPC was honoured. GPC does not change the Analytics & Performance category, which you can turn off separately.

Our Site implements Google Consent Mode v2. Google Analytics is loaded only after you accept the Analytics & Performance category; if you reject it, Google Analytics is not loaded at all. Consent signals for advertising and personalisation are sent as "denied" unless you have accepted the matching category.

Changes to This Policy

We may update this Cookie Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. When we make changes, we will update the "Last Updated" date at the top of this page.

If we make material changes, we may also:

  • Increase the policy version in our cookie consent system. Your stored choice records the version you answered; when it is older than the current version, we ask you again and do not load optional cookies until you choose
  • Notify you via email or through a notice on our Site
  • Update our consent banner with new information
