Privacy Policy

Last updated: March 2025

1. Who We Are

BioCheck (“we”, “us”, or “our”) is a link-monitoring service for content creators. Our platform checks whether your bio links are healthy, fast, and reachable — so you never lose revenue to a broken redirect.

If you have questions about this policy, please contact us at privacy@biocheck.app.

2. Information We Collect

We collect information you provide directly, including:

  • Email address and password (on signup)
  • Bio link URLs you submit for scanning or monitoring
  • Payment information processed securely by our payment provider
  • Alert and notification preferences

We also collect information automatically when you use the service:

  • IP address and browser/device type for rate limiting and security
  • Usage logs (pages visited, features used, scan timestamps)
  • Cookies and session tokens required for authentication

3. How We Use Your Information

We use collected information to:

  • Provide and improve the BioCheck service
  • Monitor your bio links and send health alerts
  • Process subscription payments and manage billing
  • Respond to support requests
  • Detect fraud, abuse, and security incidents
  • Send transactional emails (alerts, receipts, trial reminders) — no marketing emails without your consent

4. Data Retention

Link check history is retained according to your plan: 30 days on Creator, 90 days on Pro. Free plan users have no automated history. You will receive a notification 7 days before any history records are scheduled to be deleted.

Account data is retained for as long as your account is active. You may request deletion at any time by contacting us.

5. Sharing Your Information

We do not sell your personal data. We share data only with trusted service providers necessary to operate BioCheck:

  • Supabase — database and authentication infrastructure
  • Lemon Squeezy — payment processing (acts as Merchant of Record)
  • Resend — transactional email delivery
  • Vercel — hosting and serverless infrastructure

Each provider is bound by their own privacy policies and data processing agreements. We may also disclose data when required by law.

6. Cookies

We use essential cookies to maintain your authenticated session. We do not use tracking cookies or third-party advertising cookies.

7. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, export, or delete your personal data. To exercise any of these rights, contact us at privacy@biocheck.app. We will respond within 30 days.

8. Security

We use industry-standard security practices including HTTPS everywhere, bcrypt-hashed passwords (via Supabase Auth), and encrypted connections to our database. No system is 100% secure; we encourage you to use a strong, unique password.

9. Children

BioCheck is not directed to children under 13. We do not knowingly collect data from children. If you believe a child has provided us personal information, please contact us for immediate removal.

10. Changes to This Policy

We may update this policy from time to time. When we do, we will update the “Last updated” date at the top and, for material changes, notify you by email or in-app banner.
