Privacy Policy

Effective October 1, 2026

rikidev.site is the personal portfolio of Riki Zulkarnain. This page explains what data this website collects, why, and how you can ask for it to be deleted.

01Visitor data

When you open this website, simple visit statistics are recorded:

  • the page you opened and the referring site;
  • device type, browser, and operating system (from the user agent);
  • IP address and approximate country, region, and city;
  • a visitor marker made of a hash that changes every day, so visits can be counted without tracking cookies.

This data is used only to view site statistics. It is not sold or shared for advertising.

02Guestbook and likes

The name and message you write in the guestbook are stored and shown publicly. The like button on blog posts only increments a counter; a marker in your browser (localStorage) prevents double likes.

03Cookies and browser storage

This website stores your language choice (a cookie) and theme (localStorage). There are no advertising or third-party tracking cookies.

04Connected social media accounts

This website's admin panel connects to Instagram, Facebook, Threads, X, LinkedIn, and TikTok accounts owned by the site owner, to publish the owner's own content to those accounts. Only the site owner can sign in to the admin panel.

  • What is stored: access tokens and the account data needed to post (account/Page name and ID, username).
  • Tokens are stored encrypted (AES-256-GCM) and are never shared.
  • This website does not collect data about any other Facebook, Instagram, Threads, X, LinkedIn, or TikTok users.

05Third-party services

The site is hosted on Vercel and its data is stored in Supabase. AI features in the admin panel use Google Gemini to process the site owner's own notes — not visitor data.

06Your rights

You can ask for a copy or deletion of data about you at any time. See the Data Deletion Instructions, or email [email protected].

07Changes

If this policy changes, the date above will be updated.
