Cookie Policy

Last updated: April 6, 2026

1. What Are Cookies

Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work efficiently, remember your preferences, and provide information to website owners.

2. How We Use Cookies

ReplyZen.app uses cookies to ensure the proper functioning of our Service, keep you signed in, and remember your preferences. We categorize our cookies as follows:

3. Types of Cookies We Use

4. Essential Cookies

These cookies are strictly necessary for the Service to function. They enable core features such as authentication, security, and session management. Essential cookies cannot be disabled without breaking the Service.

5. Functional Cookies

These cookies remember your preferences (such as language selection and cookie consent) to provide a more personalized experience. While not strictly necessary, disabling them may result in reduced functionality.

6. Analytics & Browser Fingerprinting

With your consent (provided via the cookie banner), we collect anonymous analytics data to understand how visitors use our site. This includes:

  • Pages visited and referrer URL
  • IP address — used to determine approximate geographic location (country, city)
  • Browser information — browser name, operating system, device type
  • Screen resolution, color depth, language, and timezone
  • Device fingerprint — a hash computed from browser properties (canvas rendering, WebGL renderer, installed plugins, hardware concurrency). This is not a cookie and cannot identify you personally — it helps us count unique devices

If you decline cookies via our consent banner, no analytics data is collected. Analytics data is automatically deleted after 90 days. We do not share analytics data with any third party. All analytics processing happens on our own servers — no external analytics services (Google Analytics, etc.) are used.

7. Third-Party Cookies

ReplyZen.app does not use third-party advertising cookies. Our payment processors (LemonSqueezy, Stripe) may set their own cookies on their domains during the checkout process — these are governed by their respective cookie policies.

8. Managing Cookies

You can control and manage cookies through your browser settings. Most browsers allow you to:

  • View what cookies are stored and delete individual cookies
  • Block third-party cookies
  • Block cookies from specific sites
  • Block all cookies
  • Delete all cookies when you close your browser

Please note that disabling essential cookies will prevent you from signing in and using the Service.

9. Changes to This Policy

We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for operational, legal, or regulatory reasons. Please revisit this page periodically to stay informed.
