Privacy Policy

**Last Updated:** February 21, 2026

Welcome to A/B Test Pro (abtestpro.com). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data when you use our website and statistical calculator tools (the "Service").

1. Information We Collect (and Do Not Collect)

A/B Test Pro is designed to function without user accounts or registration. The data we interact with falls into three distinct categories:

1.1. Ephemeral Calculator Inputs (Not Stored)

Our tools require you to input numeric data (such as baseline conversion rates, audience sizes, and expected lift) to generate statistical models.

  • Strictly Ephemeral: This data is strictly non-personally identifiable. It is transmitted to our servers momentarily to process mathematical formulas and return the result to your browser.
  • No Logging or Storage: We do not process, log, save, or store these numeric inputs after the calculation is returned.

1.2. Information You Voluntarily Provide

If you choose to contact us regarding support, partnerships, or general inquiries via our contact form or direct email, we collect:

  • Your name
  • Your email address
  • The contents of your message

1.3. Automatically Collected Data (Analytics & Log Files)

To understand how our website is used and to ensure it functions correctly, we automatically collect certain standard internet and device data when you visit abtestpro.com. This data is collected via Google Analytics and server logs and includes:

  • IP addresses
  • Browser types and versions
  • Device information (e.g., operating system)
  • Pages visited, time spent on pages, and navigation paths
  • Broad geographic region (e.g., city or country level)

2. How We Use Your Information

We use the information we collect for the following limited purposes:

  • To Provide the Service: Transmitting (but not storing) your numeric inputs to return mathematical results.
  • To Communicate with You: Using your contact form submissions solely to reply to your inquiries and provide customer support.
  • To Improve Our Website: Using aggregated Google Analytics data to understand user behavior, fix technical issues, and optimize the user experience.

3. Cookies and Tracking Technologies

We use cookies and similar tracking technologies to enable Google Analytics. Cookies are small data files placed on your device.

  • Consent: Depending on your location, we will ask for your explicit consent before placing non-essential tracking cookies on your device.
  • Opting Out: You can instruct your browser to refuse all cookies. Furthermore, you can prevent Google Analytics from using your data by installing the Google Analytics Opt-out Browser Add-on.

4. Third-Party Services and Data Sharing

We do not sell your personal data for monetary compensation. We only share data with trusted third-party service providers necessary to operate our website. These providers act as our data processors:

  • Vercel (Hosting and Infrastructure): Our website is hosted on Vercel. When you use A/B Test Pro, your IP address, browser user-agent, and momentary calculator inputs are processed through Vercel's global edge network to deliver the website securely and quickly. Vercel may temporarily retain server logs to detect and prevent security threats (like DDoS attacks).
  • Google Analytics: To analyze website traffic and user behavior.

These providers are bound by strict data processing agreements and are not permitted to use your data for their own independent marketing purposes.

5. European Privacy Rights (GDPR)

If you are a resident of the European Economic Area (EEA) or the United Kingdom, you have specific rights under the General Data Protection Regulation (GDPR):

  • Lawful Basis: We process your contact information based on your explicit consent or our legitimate interest in responding to your inquiries. We process analytics data only with your explicit consent via our cookie banner.
  • Your Rights: You have the right to request access to, rectification of, or erasure of your personal data. You may also restrict or object to our processing and request data portability.
  • To exercise these rights, contact us at the email address below.

6. California Privacy Rights (CCPA / CPRA)

If you are a resident of California, the California Consumer Privacy Act (CCPA) provides you with specific rights regarding your personal information:

  • Right to Know and Delete: You have the right to request what personal information we collect, use, and share, and to request its deletion.
  • Right to Opt-Out of "Sharing": While we do not sell data for money, using Google Analytics is legally considered "sharing" personal information under California law. You have the right to opt-out of this tracking by clicking the "Do Not Sell or Share My Personal Information" link located in the footer of our website.

7. Data Retention

  • Calculations: 0 seconds (instantly discarded after processing).
  • Contact Inquiries: Retained only as long as necessary to resolve your inquiry, after which it is routinely deleted.
  • Analytics Data: Retained according to our configuration within Google Analytics (typically 14 months) before automatically expiring.

8. Children's Privacy (COPPA)

A/B Test Pro is a business-to-business (B2B) tool intended for use by adult professionals. We do not knowingly collect personal information from children under the age of 16. If you believe a child has provided us with personal information, please contact us immediately so we can delete it.
