9. California Invasion of Privacy Act (CIPA) Compliance

The California Invasion of Privacy Act (CIPA) (California Penal Code §§ 630-638) is a state law that protects the privacy of communications. We take CIPA compliance seriously and have implemented the following measures:

9.1 Our CIPA Compliance Measures

  • No Pre-Consent Tracking: We do not load any tracking scripts (including Google Analytics, Meta Pixel, or similar tools) until you explicitly consent to their use.
  • Hard Block on Decline: If you click "Decline" or opt out of non-essential cookies, we implement a hard block that prevents those tracking scripts from loading.
  • No Data Transmission Without Consent: No user data is transmitted to third parties without your explicit consent.
  • Script Blocking Technology: We use a script manager that intercepts and blocks unauthorized script injections.
  • Consent Verification: All data transmissions are verified against your consent preferences before being sent.

9.2 What This Means for You

Under CIPA, unauthorized interception of electronic communications can result in significant penalties. Our compliance measures ensure that:

  • Your browsing activity is not tracked without your knowledge and consent
  • Third-party tracking tools cannot access your data unless you explicitly allow it
  • You have full control over what data is collected and shared
  • Your "Decline" choice is respected and enforced at the technical level

9.3 CIPA and "Digital Wiretapping"

Recent legal interpretations have characterized certain tracking technologies as "digital wiretaps" under CIPA. These include:

  • Session replay tools (e.g., Hotjar, FullStory)
  • Marketing pixels (e.g., Meta Pixel, Google Ads)
  • Analytics tools that collect detailed user behavior

Our commitment: We do not use any of these tools without your explicit consent. If you decline tracking, these tools are completely blocked and cannot collect any data about your session.

9.4 Reporting Concerns

If you believe that tracking tools are being loaded without your consent, or if your "Decline" choice is not being honored, please contact us immediately. We take all such reports seriously and will investigate promptly.

You can verify our compliance by:

  • Checking your browser's Developer Tools (Network tab) to see what scripts are loaded
  • Using browser extensions that block trackers to verify they are not firing
  • Contacting us for a copy of our consent audit logs

10. Children's Privacy

Flash-Read is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have inadvertently collected personal data from a child under 13, we will take steps to delete such information promptly.

If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take appropriate action.

11. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. The most current version will always be available on this page with an updated revision date.

For material changes, we will notify users via email or through a prominent notice within the application at least 30 days before the changes take effect.
