Privacy Policy
Effective Date: October 1, 2026 • Last Revised: October 2026
1. Overview
At Markdown Signal (https://markdownsignal.com), we prioritize user privacy. This Privacy Policy details what information we collect, how it is used, and the choices you have concerning your personal data.
2. Information We Collect
We only collect information necessary to provide our services and personalize your deal alerts:
- Account Information: When you register an account, we collect your chosen username, email address, and a cryptographically salted password hash.
- Third-Party Social Login (Google & Discord OAuth): If you choose to sign in with Google or Discord, we receive your email address, basic public name, profile avatar URL, and provider account ID. We do not receive or request access to your contacts, files, or sensitive Google services.
- User Preferences: Deals saved to your watchlist, custom keyword trackers, and notification filters.
3. Google API Services User Data Policy Compliance
Markdown Signal's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
We solely request basic profile scopes (openid, email, profile) to authenticate your identity. We never share, sell, or monetize user data obtained through Google authentication.
4. How We Use Information
We use the collected information exclusively to:
- Authenticate your account session and maintain security.
- Sync watchlists and deal alerts across your devices.
- Deliver restock and price-drop notifications that you explicitly request.
- Monitor system reliability and protect against spam or malicious abuse.
5. Cookies & Local Storage
We utilize secure, HttpOnly session cookies for authenticated users to maintain encrypted sessions. Non-sensitive preferences (such as local filters) may be cached in browser localStorage for offline speed.
6. Data Retention & Account Deletion
You may request account deletion at any time by contacting support. Upon account deletion, all personal identifiers, linked OAuth identities, and saved alerts are permanently purged from our primary database.
