h4cker.app is an AI-native Hacker News reading workspace. This page explains what data the app uses and where it is stored.
Account data
When you create a h4cker account, we store your email, display name, plan status, preferences, saved items, read-later queue, reading history, and related account records.
Hacker News login
Hacker News login is a proxy login flow. Your Hacker News password is sent only for the login request and is not stored by h4cker. The Hacker News session cookie is stored in your browser local storage so the app can send comment and vote requests that you initiate.
AI features
AI summaries, translations, explanations, Daily Digest, and agent requests may send story text, comment text, selected text, and your request to the configured AI provider. AI outputs may be cached to make repeated reading faster.
Local storage
Theme, language, UI preferences, and the optional Hacker News session are stored locally in your browser. Clearing browser storage or disconnecting Hacker News removes the local Hacker News session.
Third-party services
h4cker reads public Hacker News content, links to original sources, uses Cloudflare for hosting and data storage, and may use Stripe for subscription billing.
