Privacy Policy

Last updated: 2026-05-16

devAlice respects visitor privacy. This document describes what data is collected and how.

1. Advertising

devAlice uses Google AdSense to display ads. AdSense may use cookies and similar technologies to serve ads relevant to your interests. You can opt out of personalized advertising at Google Ads Settings.

2. Analytics

We use Vercel Web Analytics and Speed Insights for visit counts and page performance. Neither uses cookies; only anonymous hash-based pageviews and Web Vitals (LCP/CLS/INP) are collected. No personally identifiable information is collected.

3. Comments

Comments on guide pages are powered by GitHub Discussions (Giscus). Posting requires a GitHub account, and GitHub's policies apply.

4. Download counters

Asset download counts are aggregated anonymously (via Supabase). No personally identifiable information is collected.

5. Authentication (M2)

You can optionally sign in with GitHub OAuth. When you do, your GitHub display name, email (if visible), and avatar URL are stored in Supabase.

6. Favorites

Signed-in users can favorite guides. Favorite records (guide URL, time added, title) are stored in Supabase under your own row only and are automatically cleaned up on account deletion (`on delete cascade`).

7. Error tracking

We use Sentry to diagnose site errors. Stack traces, request paths, and browser/OS info for exceptions are collected. For signed-in users, the user ID (uuid) may also be recorded. No personal data (email, name, favorites, etc.) is collected. Retention follows Sentry's default policy.

8. Contact
