Privacy policy

Data we collect

chandramuka.com is a static site. There is no contact form that posts data to our servers. When you tap chat or email, your device opens WhatsApp or your mail app with a starter message we prepared.

When you contact us, the data we usually receive depends on the channel you choose.

WhatsApp (including WhatsApp Business and Meta's WhatsApp Cloud API): phone number, profile name, message content, attachments you send, and conversation metadata Meta provides.
Email: email address, sender display name, message body, and attachments.
Phone: the number that calls us, if you use the phone link on the contact page.
Language choice on the site: we store a language code (id or en) in localStorage and a cookie named ckb_lang, plus a first-visit flag in localStorage (ckb_lang_seen), so your choice is remembered.
Hosting technical logs: the host may record IP address, browser type, and page requests in ordinary server logs for security and performance.

How we use the data

We use the data only to run the collaboration and keep the site working.

Reply to questions, prepare proposals, and deliver the work you asked for.
Send updates about ongoing work.
Keep the site language matching your choice.
Protect the site and limit abuse.
Meet legal duties that apply, when they do.

How long we keep data

Language choice in your browser lasts up to one year for the ckb_lang cookie, or until you clear site data. The first-visit flag in localStorage stays until you remove it.

WhatsApp and email messages stay as long as they remain relevant to ongoing work or communication, then we delete or archive them under our office practice. Data we must keep for bookkeeping or legal duties stays for the period those rules require.

Hosting logs usually rotate over weeks to months, depending on the provider. Exact timing can change; contact us if you need clarity for a specific case.

Who we share data with

We do not sell personal data. It only reaches parties needed to deliver messages or keep the site online.

Meta Platforms (WhatsApp, including WhatsApp Business and Cloud API): messages and metadata travel on Meta's infrastructure when you use WhatsApp.
Your email provider and ours: to deliver correspondence.
Cloudflare: serves the static chandramuka.com site and may process request logs and their network technical cookies.
Live office at office.chandramuka.com: a separate link from this site. If you open that page or chat with the assistant there, that service's own policy applies.
Competent authorities, only when the law requires it.

Security

The site is served over HTTPS. Access to email and WhatsApp Business inboxes is limited to people handling client communication. No system is fully immune; we match safeguards to the risk level of a small business.

Your rights under Indonesia's PDP Law

Under Law No. 27 of 2022 on Personal Data Protection, you may request actions about personal data we process, including:

Ask what data we process.
Request a copy or access to that data.
Ask us to correct inaccurate data.
Ask us to delete data within the limits the law allows.
Withdraw consent for processing that relies on consent, without affecting earlier lawful processing.
Object to certain processing where that right applies.
Lodge a complaint with the competent authority in Indonesia.

How to reach us

Policy changes

If this policy changes, we put the new version on the same page and update the effective date at the top. Material changes will be noted here. Using the site after the new date means you are reading the version then in force.
