+### Project Tick™ Trademark and Brand Policy
+
+#### 1. Ownership of the Marks
+
+Project Tick™, the Project Tick name, the Project Tick logo, and all related branding elements (collectively, the “Marks”) are trademarks of **Mehmet Samet Duman**.
+
+All rights in the Marks are reserved.
+
+This Trademark Policy governs use of the Marks independently of any open source license applicable to source code, documentation, or other materials.
+
+---
+
+#### 2. Relationship to Open Source Licenses
+
+Each repository under the Project Tick namespace is licensed under its respective open source license (e.g., MIT, BSD, Apache-2.0, GPL, MS-PL, etc.).
+
+These licenses govern the use, modification, and redistribution of source code only.
+
+Open source licenses do **not** grant:
+
+* Rights to use the Project Tick name
+* Rights to use the Project Tick logo
+* Rights to use Project Tick branding or trade dress
+* Rights to imply affiliation, endorsement, sponsorship, or official status
+
+Trademark rights are separate from copyright licenses.
+
+---
+
+#### 3. Permitted Uses
+
+The following uses are generally permitted without prior written permission:
+
+1. Factual references (e.g., “compatible with Project Tick”).
+2. Accurate description of unmodified official releases.
+3. Non-commercial commentary, research, educational, or journalistic references.
+
+Permitted use must not:
+
+* Create confusion regarding origin
+* Suggest sponsorship, approval, or endorsement
+* Present modified versions as official releases
+
+---
+
+#### 4. Modified and Redistributed Versions
+
+Open source licenses permit modification and redistribution of source code.
+
+However:
+
+* Modified versions must not use the Project Tick name or logo in a way that implies official status.
+* Forks must use distinct branding.
+* Derivative works must clearly indicate that they are modified versions.
+* Use of phrases such as “Official,” “Certified,” or similar terminology is prohibited without authorization.
+
+Permissible example:
+
+> “Based on Project Tick”
+
+Impermissible example:
+
+> “Official Project Tick Build”
+
+Unless explicitly authorized.

+* As part of a commercial SaaS service name
+* As part of a registered domain name

+
+Without prior written permission.
+
+Operating a commercial service using Project Tick source code does not grant the right to represent that service as an official Project Tick service.

+Only services directly operated by Mehmet Samet Duman under the Project Tick identity may use the Marks in a commercial context.
