1. What Are Cookies & Tracking Technologies?
Cookies are compact text files stored on your local computer, tablet, or smartphone when you browse websites. They enable web applications to remember your session credentials, preserve layout preferences, secure forms against cross-site request forgery, and evaluate website performance.
Alongside traditional HTTP cookies, Nextstep Dev may utilize complementary web technologies including Web Beacons / Pixels (microscopic images deployed to verify conversions), Browser LocalStorage (client-side data caching for instantaneous page rendering), and Server-to-Server Conversions APIs (e.g., Meta CAPI).
2. Strictly Necessary / Essential Cookies
Essential cookies fulfill the following functions:
- Edge Security & Bot Mitigation: Cloudflare edge cookies (e.g.,
__cf_bm) detect automated malicious bots, mitigate brute-force attacks, and preserve SSL/TLS sessions across global data centers. - CSRF Security Tokens: Cryptographic tokens preventing Cross-Site Request Forgery during discovery form submissions and contact inquiries.
- Server Load Balancing: Directing incoming HTTP requests evenly across AWS high-availability node clusters.
3. Performance & Analytics Tags (GA4 & Telemetry)
Analytics cookies help us understand how prospective clients and developers interact with our agency website, case studies, and engineering resources:
- Google Analytics 4 (GA4): Deploys first-party cookies (
_ga,_ga_*) to calculate visitor, session, and campaign data. GA4 is configured on our infrastructure with strict IP Masking / Anonymization enabled. - Google Tag Manager (GTM): Manages script firing rules containerized under strict asynchronous loading to ensure zero impact on Google Core Web Vitals (LCP, INP, CLS).
- Core Web Vitals Telemetry: Lightweight scripts tracking real-user performance metrics to guarantee sub-second page transitions across mobile devices.
4. Marketing Pixels & Advertising Tags (Google Ads & Meta)
These cookies are placed by certified third-party advertising platforms to measure the return on investment (ROAS) of our promotional campaigns and present relevant agency solutions:
- Google Ads Conversion Linker: Cookies (
_gcl_au,_gcl_aw) store click information from Google Search and Display ads so conversion events (such as booking an engineering sprint) are reliably attributed. - Meta Pixel & Conversions API: Operates
_fbpcookies to evaluate advertising performance across Facebook and Instagram. When combined with server-side CAPI, customer records (e.g. email) are hashed with SHA-256 encryption before transfer. - Remarketing Limitations: We do not deploy sensitive audience categories (such as health status, political views, or religion) for retargeting, strictly adhering to Google and Meta advertising policies.
