Privacy Policy

Last updated: May 23, 2026

1. Introduction

ReplyHunter ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how our Chrome extension collects, uses, and safeguards your information when you use our service.

2. Information We Collect

2.1 Browsing & Feed Data (Strictly Local)

ReplyHunter operates entirely within your browser as a client-side application. All feed analysis is performed locally on your device. We do not transmit, store, or have access to:

  • Your X (Twitter) account credentials or authentication tokens
  • Content of posts, replies, or direct messages
  • Your browsing history or activity on X

2.2 Account & Authentication Data (Transmitted Securely)

To manage your subscription and prevent multi-device abuse, we collect and securely transmit the following data when you log in:

  • Your email address
  • Your unique activation code
  • A randomly generated device ID to lock your session to your current browser

2.3 Local Storage

ReplyHunter stores the following data locally in your browser using Chrome's local storage API:

  • User preferences (theme selection, sidebar visibility, filter settings)
  • Extension configuration settings

This data remains on your device and is never transmitted to our servers or any third party.

3. How We Use Information

ReplyHunter analyzes publicly visible posts on X (Twitter) to provide engagement predictions.

The account authentication data we collect (as outlined in section 2.2) is used exclusively to:

  • Verify your active subscription status
  • Enforce our single-device usage policy
  • Provide account management and support

3.1 Communications & Onboarding

By creating an account, you agree that we may use your email address to send you essential onboarding materials, product updates, and service announcements to help you use ReplyHunter effectively.

You maintain the right to opt-out of non-critical communications at any time by clicking the "unsubscribe" link included at the bottom of these emails, or by managing your preferences in your account dashboard under Email Communications.

4. Data Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties. ReplyHunter is designed with privacy at its core:

  • We ensure that X (Twitter) feed data is not transmitted to our servers. Only extension authentication data is processed through our backend for login and license verification purposes.
  • We do not share your personal account information or browser extension usage data with any third parties.

4.1 Marketing and Advertising Attribution

As an exception to the above, our promotional website (replyhunter.co) utilizes third-party advertising and analytics services (such as X/Twitter Ads) to measure the performance of our marketing campaigns.

We may share anonymized, aggregated website visitor data with these platforms solely for attribution and targeted advertising purposes.

Your social media feeds, private messages, and extension interactions are never accessed by or shared with these advertising partners.

5. Cookies and Tracking Technologies

5.1 The Browser Extensions

The ReplyHunter browser extensions (for Chrome and Firefox) operate locally on your device and do not utilize cookies, web beacons, or third-party tracking technologies.

5.2 The Promotional Website

Our promotional website uses cookies and similar tracking technologies (e.g., tracking pixels) to enhance your browsing experience, analyze site traffic, and assess the effectiveness of our marketing.

When visiting our website, you are presented with a cookie consent banner allowing you to accept or decline the use of these non-essential marketing cookies.

You may revoke this consent at any time by clearing your browser cookies.

6. Browser Extension Permissions

ReplyHunter requests the following permissions to function:

Host Permissions (x.com, twitter.com)

Required to inject the extension's interface and analyze publicly visible posts on X (Twitter). This permission allows the extension to read page content and insert visual elements but does not grant access to your account or private data.

Storage Permission

Used to save your preferences (theme selection, sidebar settings) locally on your device. This data is stored using Chrome's local storage API and never leaves your browser.

7. Data Security

Feed data remains entirely local, while the ReplyHunter extension authentication data is securely transmitted over encrypted connections (HTTPS) and stored securely by our authentication provider. We recommend keeping your browser and operating system updated to ensure the latest security protections.

8. Children's Privacy

ReplyHunter is not directed to individuals under the age of 13. We do not knowingly collect information from children. If you believe a child has used our extension, please contact us.

9. International Users

ReplyHunter is available globally. While feed analysis occurs locally, the ReplyHunter extension authentication data may be transferred to and maintained on servers located outside of your state or country.

10. Your Rights & Account Management

You maintain full control over your locally stored preferences and your account data.

Local Data Control

  • You can clear your local preferences at any time by clearing your browser data.
  • Please note: Uninstalling the extension does not automatically release your registered device ID from our servers. To fully clear your active device session, you must explicitly click "Sign Out" from within the extension, or click "Disconnect Device" from your web account dashboard.

Account Deletion

  • You may initiate a comprehensive account deletion request at any time via the account settings portal or by submitting a request to our support email (info@replyhunter.co).
  • Upon processing, your registered email address shall be permanently purged from our servers. We retain only an anonymized account record for accounting purposes.

Subscription Cancellation

  • In the event of a paid subscription cancellation, your account shall remain active through the conclusion of the current billing cycle.
  • Subsequently, the account shall transition to an inactive state, pending any formal request for complete deletion.

11. Changes to This Privacy Policy

We may update this Privacy Policy periodically. Any changes will be posted on this page with an updated "Last Modified" date. We encourage you to review this policy regularly. Continued use of ReplyHunter after changes constitutes acceptance of the updated policy.
