If you want the broader explanation of how Syqnal handles personal data, use the Privacy Policy. This page focuses specifically on cookies and analytics controls.

§ 01

What Are Cookies

Cookies are small text files that a website places on your device (computer, tablet, or mobile phone) when you visit it. They allow the website to remember your actions and preferences over time, so you don't have to re-enter them each time you visit.

Cookies can be classified in several ways:

Session cookies are temporary and are deleted automatically when you close your browser. They are used to keep you logged in during a single browsing session.
Persistent cookies remain on your device for a set period of time (defined by an expiry date). They are used to remember your preferences across sessions.
First-party cookies are set by Syqnal directly (the website you are visiting).
Third-party cookies are set by external services we use, such as Google Analytics and PostHog.

We use a minimal set of cookies — only what is necessary to provide authentication and basic platform functionality, plus optional analytics cookies to help us improve the Platform. We do not use advertising or tracking cookies.

§ 02

Cookies We Use

Essential cookies are required for the Platform to function. They handle authentication and security and cannot be disabled without breaking your ability to log in and use the Platform.

Name	Type	Purpose	Duration
next-auth.session-token	Session	Authentication session — keeps you logged in during your browser session	Session
next-auth.csrf-token	Session	Cross-site request forgery (CSRF) protection — prevents unauthorized form submissions	Session
__Secure-next-auth.session-token	Persistent	Secure authentication session — used when “Remember me” is active or when your browser persists sessions	30 days
syqnal-theme	Persistent	Stores your dark/light mode preference so it persists across sessions	1 year

Google Analytics 4 cookies collect anonymized usage data. They can be declined via your browser settings or the opt-out link in Section 5. Declining these cookies has no impact on Platform functionality.

Name	Type	Purpose	Duration
_ga	Persistent	Google Analytics 4 user identifier — distinguishes unique visitors for aggregate traffic analysis	2 years
_ga_*	Persistent	GA4 session and measurement ID tracking — records session count and duration per user	2 years
_gid	Persistent	GA4 daily unique visitor identification — used to count unique visitors per 24-hour period	24 hours

PostHog cookies support product analytics, feature flags, and session recording. They can be declined without affecting Platform functionality. See Section 3 for details on what PostHog records.

Name	Type	Purpose	Duration
ph_*	Persistent	PostHog user identity and session continuity — associates events across page views for funnel and retention analysis	1 year
posthog_session	Session	PostHog session tracking — groups events into individual sessions for session recording and analysis	Session

§ 03

What PostHog Records

PostHog is our product analytics platform. It helps us understand how the Platform is actually used so we can improve it. Here is what PostHog does and does not capture:

What PostHog captures

Page views and navigation paths through the Platform
Button clicks and feature interactions (for example, clicking “Request Verification” or opening a mentor's profile)
Feature usage counts and frequency (how often features like Gap Analysis or the Smart BOM are used)
Funnel analysis (for example, tracking how many users who start the onboarding flow complete it)
Retention and re-engagement patterns
A/B test and feature flag assignment (which variant of a UI you are shown)
Session recordings — which capture mouse movements, scrolling, and clicks, and are used to diagnose UX issues

What PostHog does NOT capture

Passwords or authentication credentials (all password fields are excluded)
Payment information (Stripe handles payments; PostHog has no access to payment forms)
Content of form fields in sensitive contexts (such as project schematics, BOM data, or personal bio fields — these are excluded from session recordings by default)
Precise GPS location

Session recordings automatically mask input fields and sensitive elements. If you prefer that no session recordings are taken of your usage, you can opt out of PostHog cookies via your browser settings or the opt-out mechanism described in Section 5.

PostHog data is stored in PostHog's US-based infrastructure. EU data residency is available on request for institutional accounts — submit a Legal & Privacy Request if this is required for your institution's compliance needs.

§ 04

What Google Analytics Records

Google Analytics 4 helps us understand aggregate traffic patterns on the Platform. We have configured GA4 with the following privacy settings:

IP anonymization: IP addresses are anonymized before storage. GA4 cannot identify individual visitors by IP address.
No cross-site tracking: We do not enable Google Signals, which would link Platform usage to your Google account activity across other sites.
No advertising features: We do not use GA4's advertising or remarketing features.
Data retention: GA4 event data is retained for 14 months under our configuration.

What GA4 captures

Anonymized page views and page load performance
Referral source (how you arrived at the Platform — e.g., search engine, direct link)
Geographic region at country level only (not city or postal code)
Device type (desktop, mobile, tablet) and operating system category
Session count and duration in aggregate

What GA4 does NOT capture

Your name, email address, or any other personal identifier
Precise location (city, postal code, GPS coordinates)
Content you enter into forms
Cross-site behavioral data

§ 05

How to Control Cookies

Browser settings

Most browsers allow you to block or delete cookies through their settings. Note that blocking essential cookies will prevent you from logging in to the Platform.

CHROME

Settings → Privacy and security → Cookies and other site data → See all site data and permissions → search for syqnal.com

FIREFOX

Settings → Privacy & Security → Cookies and Site Data → Manage Data → search for syqnal.com

SAFARI

Safari → Settings (or Preferences) → Privacy → Manage Website Data → search for syqnal.com

EDGE

Settings → Cookies and site permissions → Cookies and site data → See all cookies and site data → search for syqnal.com

Google Analytics opt-out

Google provides a browser add-on that prevents GA4 from collecting data about your visits. Download and install it from: tools.google.com/dlpage/gaoptout

PostHog opt-out

To opt out of PostHog analytics and session recording, you can block cookies with the name prefix ph_ using your browser's cookie management tools (see above). An in-Platform opt-out toggle will be added to this page in a future update.

Do Not Track

We respect the Do Not Track (DNT) browser header. When DNT is enabled in your browser, we will not initialize Google Analytics or PostHog tracking for your session. Essential cookies are not affected by DNT as they are required for Platform functionality.

§ 06

Impact of Disabling Cookies

The impact of disabling cookies depends on which category you disable:

Essential cookies: Cannot be disabled without breaking Platform functionality. If you block all cookies from syqnal.com, you will not be able to log in, and your theme preference will not be saved. These cookies are strictly necessary for the service you have requested.
Google Analytics 4 cookies (_ga, _ga_*, _gid): Disabling these cookies has no impact on Platform functionality. You will still be able to use all features. We will simply have less information about aggregate usage patterns for that session.
PostHog cookies (ph_*, posthog_session): Disabling these cookies has no impact on Platform functionality. Feature flags controlled by PostHog may fall back to their default values if the PostHog library cannot initialize, but all Platform features will remain accessible.

In short: you can block all analytics and product cookies with zero impact on your ability to use Syqnal. Only the essential authentication and theme-preference cookies affect Platform functionality.

§ 07

Updates to This Policy

We will update this Cookie Policy whenever we add, change, or remove cookies from the Platform. The “Last updated” date at the top of this page reflects the most recent revision.

For material changes — such as adding a new third-party analytics provider or changing the scope of data collected — we will notify registered users by email before the changes take effect.

Your continued use of the Platform after updates to this Policy constitutes your acceptance of the revised Policy.
