Privacy Policy

Last updated: February 12, 2026

PostGuard ("we," "us," or "our"), operated by Lumicid, is committed to protecting your privacy. This Privacy Policy describes how we collect, use, store, and share your personal information when you use our TikTok performance monitoring service at lumicid.com (the "Service").

1. Information We Collect

Account Information

When you create an account through Clerk (our authentication provider), we receive your email address, name, and profile information. We do not store passwords — authentication is handled entirely by Clerk.

TikTok Data

When you add a TikTok profile for monitoring, we collect publicly available data including your TikTok username, post URLs, and engagement metrics (views, likes, shares, comments, and saves). We do not access private TikTok data or require your TikTok login credentials.

Billing Information

Payment processing is handled by Stripe. We receive subscription status and billing period information but do not store credit card numbers or detailed payment information directly.

Usage Data

We collect information about how you interact with our Service, including monitoring configurations, alert preferences, notification email addresses, and feature usage patterns.

2. How We Use Your Information

We use your information to:

  • Provide and maintain the monitoring service, including fetching TikTok metrics and detecting drops.
  • Send email alerts when significant metric drops are detected on your monitored posts.
  • Process subscription payments and manage your billing through Stripe.
  • Communicate with you about your account, service updates, and support requests.
  • Improve and optimize the Service based on usage patterns and feedback.
  • Ensure the security and integrity of the Service.

3. Data Storage and Security

Your data is stored in Convex, our serverless database provider. We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction.

Metric snapshots are stored as immutable records to maintain data integrity. Snapshot retention periods are based on your subscription plan (30 to 90 days, or indefinitely for higher-tier plans).
