What data we collect
We collect anonymous aggregate analytics via Plausible (an EU-hosted, privacy-focused analytics service). Plausible records:
- The URL you visited
- The referring site (if you arrived from a link)
- Browser + operating system family (e.g. “Chrome on macOS”)
- Country-level location (derived from your IP, then discarded)
- Screen size category (mobile / tablet / desktop)
Plausible does not use cookies, does not store your IP address after deriving country, does not fingerprint your browser, and does not track you across other sites. The full Plausible data policy is at plausible.io/data-policy.
We also use Vercel Analytics for aggregate page-speed metrics. Vercel does not set tracking cookies; it uses anonymized request data to compute Web Vitals. Vercel’s policy: vercel.com/legal/privacy-policy.
Cookies
We use one category of cookies only: strictly necessaryones set by Vercel (our hosting provider) for content delivery and basic security (e.g. anti-DDoS). These don’t track you and don’t require consent under GDPR.
We do not use:
- Marketing or advertising cookies
- Cross-site tracking cookies
- Third-party analytics cookies (Google Analytics, Meta Pixel, etc.)
- Session-replay cookies (Hotjar, FullStory, etc.)
Affiliate links
Pages featuring CPUs and GPUs include “Buy on Amazon” links that may earn us a small commission if you make a purchase. We don’t share any of your data with Amazon — when you click the link, Amazon may set its own cookies under its policy. See the dedicated affiliate disclosure for the full details.
Your rights (GDPR / CCPA / UK-GDPR)
Because we don’t store personal information about you, most data-subject requests resolve to “there’s nothing to delete or correct.” That said, you have the following rights:
- Right to access — request a copy of any data we hold about you
- Right to rectification — request correction of inaccurate data
- Right to erasure (“right to be forgotten”) — request deletion of any data we hold
- Right to object — opt out of aggregate analytics (instructions below)
- Right to data portability — receive any data you provided in a structured format
- Right to lodge a complaint — file a complaint with your national data protection authority
Email sm.salmanahmed47@gmail.com with any request. We respond within 30 days.
Opting out of analytics
To disable Plausible Analytics on this site, install any DNS-level ad blocker (NextDNS, AdGuard, Pi-hole), use Brave browser, or enable the “Do Not Track” header in your browser (Plausible honors DNT).
Data retention
Plausible aggregate data is retained indefinitely (it cannot identify individuals). Vercel server access logs are retained for 90 days, then permanently deleted. We don’t maintain any other data store about visitors.
Children
This site is intended for general audiences. We do not knowingly collect data from children under 13 (COPPA) or under 16 (GDPR). If you believe we have collected such data, email sm.salmanahmed47@gmail.com and we will delete it immediately.
International transfers
Plausible is hosted in the EU. Vercel is a US company with infrastructure globally. Both have Standard Contractual Clauses (SCCs) in place for EU-to-US data transfer where applicable. We do not transfer any data to countries outside these arrangements.
Changes to this policy
If we materially change how we handle data, we’ll update the effective date at the top of this page and announce the change in a footer notice for 30 days.
