Privacy Policy

Last updated: March 15, 2026

1. Introduction

Markum ("we," "our," or "Company") operates a project management and client tracking platform designed for creative agencies and freelancers. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our service.

Scope: This policy applies to all visitors and users of markum.io and our Markum service (the "Service").

2. Information We Collect

Account Registration

Full name, email address, company name, job title, phone number (optional), password and authentication credentials, billing address and payment information (processed through Stripe).

Service Usage

Project details, timelines, task descriptions, client information, team member information, comments, notes, messages, and uploaded files related to projects.

Usage Data

Log data including IP address, browser type, operating system, pages visited, time spent on pages, referring URLs, device information, and cookies (see Section 5).

Cancellation Feedback

When you cancel your subscription, we provide an optional form where you may share the reason for your cancellation and any additional feedback. Submitting this information is entirely voluntary - your cancellation is processed regardless of whether you respond.

What we collect: If you choose to respond, we collect your selected cancellation reason and any written feedback you provide at that time.

Why we collect it: We use this information to improve our products and to potentially offer you personalized re-engagement offers, discounts, or product updates based on the reason you shared.

Legal basis (GDPR): Legitimate interest (GDPR Art. 6(1)(f)). Analyzing voluntary cancellation feedback and conducting proportionate win-back outreach is a legitimate commercial interest that does not override your rights, given the data is limited, non-sensitive, and voluntarily provided.

Retention: This data is retained for 24 months from your cancellation date. After 24 months, it is automatically and permanently deleted from our systems.

Your rights: You may request deletion of your cancellation feedback at any time by contacting us at privacy@markum.io. Deletion requests are honored within 30 days. EU/EEA residents have the right to object to this processing at any time under GDPR Art. 21.
