Removing, bypassing, or altering watermarks, signatures, or protections is strictly prohibited.
Using the obfuscator with malware, RATs, or harmful software is strictly prohibited. If your file is reported as malicious, your license will be immediately revoked.
Reverse engineering, decompiling, or disassembling the obfuscator itself is prohibited. Additionally, providing samples of any obfuscator feature to third parties for the purpose of deobfuscation is strictly forbidden.
Each license is personal, non-transferable, and limited to one (1) individual on one (1) computer device. Sharing, leasing, lending, sublicensing, transferring, reselling, or offering the Service as a third-party service or protection is prohibited.
Use of the obfuscator in virtual machines (VMs), sandboxes, emulators, cloud instances, shared systems, or any multi-user or hosted environments is strictly prohibited.
For each license, HWID reset requests are limited to a maximum of two (2) times per month.
All purchases are final. Refunds, chargebacks, or payment reversals are not allowed under any circumstances.

Rika .NET collects only two pieces of data, both solely for license enforcement and security purposes (legitimate interest). No personal information or file contents are ever collected.
The process: Your file is uploaded → obfuscated on our server → returned to you → immediately deleted with zero trace.
If you are located in the EU, you have the right to request access to, correction of, or deletion of your personal data. To submit a request, contact [email protected]. We will respond to your request within 30 days.
Please note: requesting deletion of your HWID or IP will permanently invalidate your license with no refund.
We do not share, sell, or distribute any collected data to third parties. All data is stored securely and used solely for the purposes stated above.
We built this because we needed it and nothing out there was good enough.

Developed & Hosted Here
We work out of Istanbul, Turkey. Development, hosting, support, it all runs from here.
We started writing this in November 2024. At first it was just something we put together for our own use. Then it kept growing and we decided to ship it properly.
We went through a lot of .NET obfuscators over the years. Most of them worked fine for a while, then updates stopped and support went quiet. On top of that, deobfuscators for those tools kept popping up, making them pretty much useless. You'd end up searching for alternatives again, finding the same stale options. We got tired of that cycle and wrote our own. Rika .NET is what we wanted to exist from the start.
