Privacy & Cookies Policy

Last updated: May 2026

This Privacy & Cookies Policy applies to all websites, projects, tools, and content operated by me (referred to as “I,” “me,” or “my”), including this site and any other sites I own or operate (collectively, the “Sites”).

All Sites are personal hobby learning projects where I document my journey in public as a beginner. I aim to keep things simple and privacy-friendly.

1. What Data I Collect

I do not directly collect or store personally identifiable information such as your name, email address, or account data.

However, basic technical data (such as IP address, request data, browser type, and performance metrics) may be processed automatically by infrastructure providers to operate and secure the Sites.

2. Hosting & Analytics

The Sites are hosted on Cloudflare, which provides security, performance, and privacy-focused analytics.

Cloudflare Web Analytics does not use cookies, localStorage, or fingerprinting to identify individual users.

Cloudflare may process limited technical data (such as IP addresses and request metadata) to provide its services. I do not personally access or store this data.

3. Legal Basis for Processing

Any limited data processing that occurs is based on legitimate interests, specifically to ensure the security, performance, and basic functionality of the Sites.

4. Users in the European Economic Area (EEA)

If you are located in the European Economic Area (EEA), you may have rights under data protection laws such as the General Data Protection Regulation (GDPR).

Because I do not directly collect or store personal data, I generally do not have the ability to identify or access individual user data.

Limited technical data may still be processed by infrastructure providers (such as Cloudflare) to operate and secure the Sites.

5. Interactive Tools & Client-Side Features

All interactive features — including code editors (such as Ace.js), animations, simulators, and calculators — run entirely in your browser.

Any temporary data (such as settings or unsaved work) is stored locally in your browser using localStorage or sessionStorage and is not transmitted to my servers.

6. Cookies

The Sites use only strictly necessary cookies provided by Cloudflare for essential security and performance functions.

I do not use advertising cookies, tracking cookies, or third-party behavioral analytics.

7. External Links & Embedded Content

The Sites may contain links to or embedded content from third-party services (such as documentation, videos, or social media posts).

I do not control and am not responsible for how these third parties collect, use, or handle your data. You should review their privacy policies separately.

8. Data Retention

I do not retain personal data about visitors.

Third-party providers (such as Cloudflare) may retain limited technical data in accordance with their own policies.

9. Your Rights

Depending on your location, you may have rights under applicable data protection laws.

Because I do not directly store personal data, I generally do not have access to identifiable user information.

If you have questions or concerns, you may contact me and I will do my best to assist.

10. Children’s Privacy

The Sites are not intended for children under the age of 13, and I do not knowingly collect personal data from children.

11. Changes to This Policy

I may update this policy as the Sites evolve. The “Last updated” date reflects the latest version. Continued use of the Sites means you accept the updated policy.
