Privacy Policy

Last updated: [insert date]

1. Overview

Knock Knock provides website visitor identification at a company level.

We do not collect or process personal data about individual users.

We operate using network-level signals and company-level inference.

2. What data we collect

When a website installs our tracking script, we may collect:

  • IP address (processed server-side)
  • Page URL visited
  • Referrer URL
  • User agent (browser/device type)
  • Timestamp of visit
  • Session identifier (temporary, non-cookie based)

This data is used to identify company-level website activity.

3. How we use data

We use collected data to:

  • Identify companies visiting a website
  • Display visit activity (pages viewed, frequency)
  • Improve signal quality and filtering
  • Maintain system performance and security

We do not use this data for advertising or resale.

4. Company identification

Knock Knock attempts to match IP addresses to companies using:

  • reverse DNS lookups
  • domain analysis
  • filtering of infrastructure providers (e.g. cloud, ISP traffic)

This process is probabilistic and not guaranteed to be accurate.

We only display data where there is a reasonable confidence level.

5. What we do not collect

We do not:

  • identify individuals
  • collect names, emails, or phone numbers
  • use cookies or persistent trackers
  • track users across different websites

6. Data retention

We store:

  • IP mappings for a limited period (to improve performance and reduce repeat processing)
  • event data associated with website activity

Retention periods vary depending on data type and confidence level.

7. Data sharing

We do not sell or share collected data with third parties.

Data is only accessible to:

  • the website owner using Knock Knock
  • internal systems required to operate the service

8. GDPR and compliance

Knock Knock operates at a company level and does not process personal data.

However, we:

  • minimise data collection
  • avoid personal identifiers
  • allow customers to control usage on their own websites

Customers are responsible for ensuring their own compliance obligations.

9. Security

We take reasonable measures to protect data, including:

  • secure storage
  • restricted access
  • standard infrastructure protections

No system is completely secure.

10. Changes

We may update this policy over time.

Continued use of the service means acceptance of the latest version.
