Privacy Policy

This Privacy Policy explains how I, Nyochembeng Enzo Nkengafack, collect, use, and protect the personal information you provide when you use my portfolio website (the "Site"). By using the Site, you agree to the practices described in this policy.

1Who I Am

I am a Software Engineer currently based in Grottaferrata, Rome, Italy. This Site is my personal portfolio where I showcase my work, share blog posts, and make it easy for potential clients and collaborators to reach me.

• Name: Nyochembeng Enzo Nkengafack

• Email: nyochembengn@gmail.com

• Location: 28 Via della Pedica, Grottaferrata, Rome, Italy

2What Information I Collect

I only collect personal information when you voluntarily provide it, or when it is automatically generated through your interaction with the Site.

2.1Contact Form

When you fill out and submit my contact form, I collect the following:

• Your full name
• Your email address
• Your purpose of contact (selected category)
• Your message

I forward this information directly to my personal email to respond to you. I do not store any of this data in a database.

2.2Blog Comments

When you leave a comment on one of my blog posts, I collect your display name and email address. I save these credentials in my database to identify you as the author of your comments. They are also saved in your browser's local storage so that the Site can recognize you as the commenter on future visits — with no sign-in or account creation required.

2.3Comment Likes

When you like a comment, I do not collect or store any personal credentials in my database. However, a record of your like is saved in your browser's local storage permanently (until you clear your browser data) to prevent you from liking the same comment more than once.

2.4Blog Reactions

When you react to one of my blog posts to express how you felt after reading it, I do not collect or store any personal identity in my database. Your reaction is stored locally in your browser for up to 7 days, after which it expires automatically. I use this solely to understand how my content resonates with readers.

2.5Newsletter Subscription

When you subscribe to my newsletter, I collect your email address. I use it to send you updates whenever I publish or significantly update a project or blog post. Your email is managed through Resend.

2.6AI Assistant

My Site includes an AI-powered assistant built on the Grok model. Your conversation history with the assistant is stored temporarily in your browser's local storage for the duration of your browsing session. Once you close or restart your browser, the chat history is permanently cleared. I never store your chat history on my servers or in any database.

2.7Analytics

I use Vercel Analytics to collect anonymized, aggregated data about how visitors use my Site — such as page views, referrer URLs, device type, and geographic region. This data contains no personally identifiable information and cannot be linked to any individual visitor.

2.8Bot Protection & Rate Limiting

I use Google reCAPTCHA on my forms to protect against spam and automated submissions. reCAPTCHA may collect hardware and software information from your device and send it to Google for analysis. This is governed by Google's Privacy Policy.

I also use Upstash for rate limiting to protect my Site against abuse and excessive automated requests. Upstash may transiently process IP addresses or request metadata for this purpose.

3How I Use Your Information

I use the information I collect strictly for the following purposes:

Contact form data: To read and respond to your message via my personal email.

• Blog comment credentials: To identify you as the author of your comments and display them correctly.
• Comment likes: Stored locally in your browser to prevent duplicate likes.
• Blog reactions: Stored locally and temporarily to understand overall reader sentiment on my posts.
• Newsletter email: To notify you of new or updated projects and blog posts.
• AI chat history: Stored temporarily in your browser for session continuity only. Never transmitted to or stored on my servers.
• Analytics data: To understand how visitors interact with my Site and to improve its content and performance.
• reCAPTCHA data: To verify that form submissions are made by real human users.
• Rate limiting data: To protect my Site from abuse and ensure a fair experience for all visitors.

4Legal Basis for Processing

I process your personal data based on the following legal grounds under the GDPR:

1. Consent: by submitting the contact form, subscribing to my newsletter, or leaving a blog comment, you explicitly consent to the collection and processing of your data for the purposes described above.

7Cookies & Local Storage

I do not use advertising or tracking cookies on my Site. Vercel Analytics operates without cookies, relying entirely on anonymized, aggregated signals.

That said, my Site does make use of browser local storage for the following functional purposes:

1. Recognizing you as the author of your blog comments on return visits
2. Remembering your comment likes to prevent duplicates
3. Temporarily storing your AI assistant conversation history during your session
4. Storing your blog post reaction for up to 7 days

None of this local storage data is used for advertising or cross-site tracking, and it never leaves your device except as described in this policy.
