Privacy Policy

Overview

TechCompare ("we", "our", or "us") operates this website. The site, including all calculators and comparison tools, runs entirely in your browser and does not collect or transmit any personal data.

Data we do not collect

We never ask for and never store:

• Usernames, email addresses, or account credentials.
• Payment information (the site is free to use).
• Tracking cookies for advertising. We do not currently set any first-party tracking cookies.

Local calculators and tools

Every comparison, unit conversion, and calculator on the site runs locally in your browser. Inputs you type into those tools are never transmitted to us. Your saved preferences (unit choices, theme) live in your browser's local storage and are not sent anywhere.

Log files

As with most websites, our hosting provider maintains short-lived server access logs that include your IP address, user-agent, and requested URL. These logs exist for availability and abuse-response purposes, are not copied into any database we control, and are retained according to our hosting provider's policy.

Local storage

Your browser's local storage is used to remember preferences (such as unit settings). This data stays on your device and is never transmitted to us. You can clear it from your browser settings at any time.

Realtime color sync

The Color Sync tool lets you compare colors across multiple devices in realtime. When you create or join a session, the color, gradient, and spectrum settings you choose are transmitted through Supabase Realtime to every other device in the same session. This is opt-in: the tool only sends data when you actively create or join a session with a code.

The only data transmitted is the color state itself (HSL values, gradient parameters, and cycle timing) plus a random 4-character session code. No personal data, account information, or identifiers are sent. Session codes are random, not tied to accounts, and the realtime channel is ephemeral: nothing is written to any database and the channel closes when the last device leaves.

Supabase processes these realtime messages as a message broker under their own privacy policy. If you do not create or join a session, no data is transmitted for this feature.

Third-party services

Site assets are served by our hosting provider (Vercel). This provider processes data strictly on our behalf and under their own security controls. We do not embed third-party advertising scripts on the site.

We use Supabase as our realtime message broker for the Color Sync tool and as the backend for our benchmark leaderboard. Supabase processes realtime messages and leaderboard submissions under their own privacy policy. The Color Sync feature sends only color state and a random session code (see the "Realtime color sync" section above); no personal data is transmitted.

We use two cookieless analytics services to understand which tools people find useful and to monitor page performance:

• Vercel Analytics and Speed Insights - tracks aggregate pageviews and Core Web Vitals (LCP, INP, CLS) without cookies or cross-site tracking. No personal identifiers are collected.
• Ahrefs Analytics - a lightweight, cookieless analytics script that counts pageviews and referral sources. It does not set cookies or build cross-site user profiles.

Neither service uses cookies or builds cross-site user profiles. Both collect only aggregate, anonymized data (pageview counts, country-level location, and referrer URLs) that cannot be traced back to an individual user.

Community links

The site links to our Discord community in the footer. Discord has its own privacy policy and data practices that are separate from ours. We do not control what Discord collects when you visit their platform.

Changes to this Privacy Policy

We may update this Privacy Policy from time to time. Material changes will be announced by updating the "Last updated" date below.
