Privacy Policy

Last updated: January 26, 2026

This policy explains how SerialFlow collects, uses, and shares information when you use the Service.

1. Information We Collect

Account Information

When you create an account, we collect:

  • Email address
  • Name (optional)
  • Password (stored as a secure hash)

Usage Data

We automatically collect information about how you use the Service, such as:

  • Session activity and duration
  • Features used
  • Device and browser information
  • Error logs and crash reports

Serial Data

When you use SerialFlow, we process the serial or text streams you connect to the Service. We may store this data if you choose to save or export it (when those features are available). At this time, stored data may be stored without encryption, and we do not provide end-to-end encryption. We may introduce additional security options in the future and will update this policy if we do.

Support and Communications

If you contact us, we collect the information you provide so we can respond.

Billing Information

If we offer paid plans, a payment processor will collect payment details. We do not store full payment card numbers on our servers.

2. How We Use Your Information

We use collected information to:

  • Provide and maintain the Service
  • Improve and personalize your experience
  • Send important updates about your account
  • Respond to support requests
  • Detect and prevent fraud or abuse

3. Data Storage and Security

We use reasonable technical and organizational safeguards to protect your information. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

4. Data Sharing

We do not sell your personal information. We may share data with:

  • Service providers that help us operate the Service (hosting, analytics, support, and monitoring)
  • Law enforcement or regulators when required by law
  • Other parties with your explicit consent

We currently use PostHog for analytics and Sentry for error monitoring.

5. Cookies and Similar Technologies

We use cookies and localStorage to:

  • Keep you signed in
  • Remember preferences (like theme)
  • Measure usage and improve the Service

You can control cookies through your browser settings.

6. Data Retention

We retain account information for as long as your account is active. If you delete your account, we delete or anonymize your personal information within a reasonable period, unless retention is required by law.

7. Your Rights and Choices

Depending on your location, you may have the right to:

  • Access your personal data
