Privacy Policy

Last updated June 13, 2026

Welcome to Zilfu ("we," "our," or "us"). This Privacy Policy explains how we collect, use, and protect information when you use our social media management platform at https://zilfu.app. By accessing or using our Service, you agree to the terms outlined in this policy.

1. Information We Collect

Our service collects specific types of information:

  • Personal Information: When you create an account, we collect your name and email address. We do not collect phone numbers.
  • Usage Data: We gather data about service usage, including IP addresses, browser types, and page visits.
  • Cookies: We employ cookies to enhance user experience, which you can manage through your browser settings.

2. Use of Information

We utilize collected information for these purposes:

  • Service provision and maintenance
  • Service improvement through analysis using PostHog
  • Usage monitoring and service optimization

3. Analytics Implementation

Our service uses PostHog (provided by PostHog Inc.) to understand website usage patterns. PostHog data is processed on EU-based servers (eu.posthog.com). It collects:

  • IP addresses
  • Browser and device information
  • Page visit and interaction data
  • For signed-in users, an identifier linked to your name and email address

PostHog acts as our data processor and uses this information solely to provide analytics on our behalf. We do not sell this data or share it with third parties for advertising. For more detail, see PostHog's privacy policy.

Until you accept analytics cookies, PostHog runs in a cookieless mode: it stores nothing on your device and counts visits using a privacy-preserving identifier derived on the server, without cookies or local storage. Accepting analytics cookies enables full, cookie-based analytics (including linking activity to your signed-in account); you can withdraw this at any time from “Cookie settings”, which returns PostHog to the cookieless mode and clears its cookies.

4. Affiliate Partnership

Zilfu runs an affiliate program using Rewardful. When you arrive through an affiliate link, this system:

  • Stores a referral identifier locally on your device
  • Communicates with Rewardful to attribute the referral and credit the affiliate
  • Does not share your personal data with Rewardful or other third parties for advertising

For more detail, see Rewardful's privacy policy.

Cookies are small data files stored on your device that help remember your preferences, understand site usage, and enhance your browsing experience. We group the cookies and similar technologies we use into three categories:

  • Strictly necessary: Required for the site to function, including authentication, security, and remembering your current workspace. These are always active and cannot be disabled.
  • Analytics: Help us understand how visitors use Zilfu so we can improve the product. We use PostHog, processed on EU-based servers.
  • Marketing: Attribute sign-ups to the partner who referred you so we can credit our affiliates (Rewardful), and measure sign-ups that originate from our ads on Meta using the Meta Pixel and Conversions API (cookies _fbp and _fbc).

When you first visit, a consent banner lets you accept all categories, reject everything that is not strictly necessary, or choose individually. Non-essential cookies are not set until you opt in. You can review or change your choices at any time using the “Cookie settings” link in the footer, and you can also manage cookies through your browser settings, though disabling them might limit certain site functionalities.

We also offer an in-app support chat (Crisp) so you can reach us for help. The chat is available within the app, but it only stores a conversation cookie once you open and use it — a service you have explicitly requested — so it sits outside the categories above. See Crisp's privacy policy.

With your consent to marketing cookies, we measure sign-ups that originate from our advertising on Meta (Facebook and Instagram). We use the Meta Pixel together with Meta's Conversions API to record a single account-creation event. We share a hashed (irreversible) version of your email address and an account identifier, along with technical data such as your IP address and browser, so Meta can attribute the sign-up to a campaign and deduplicate the browser and server signals. This stores the _fbp and _fbc cookies on your device. Nothing is collected or sent to Meta unless you accept marketing cookies, and you can withdraw consent at any time from the “Cookie settings” link, which clears these cookies. See Meta's privacy policy.

6. Security Measures

While we don't collect personal data, we maintain robust security measures to protect all collected information from:

  • Unauthorized access
  • Improper disclosure
  • Potential misuse

7. Policy Updates

This privacy policy may be updated periodically. We will:

  • Post any changes on this page
  • Consider changes effective upon posting
  • Notify users of significant updates

8. Contact Information
