Privacy Policy
This policy explains what personal information Sizlon collects through this website and how we use it. Data your organization processes with Sizlon products is handled separately — see "Product data" below.
Scope
This policy covers sizlon.io and the business inquiries we receive through it. It does not cover data you process inside a licensed Sizlon product, which runs in your own environment.
What we collect
When you use the contact form we collect the details you provide — name, work email, company, and your message.
When you request a verification, we also collect your company name, business registration number (사업자등록번호), contact name, phone, work email, the notice reference, and any bid documents you upload for verification. The business registration number identifies your company across requests and for billing; uploaded documents are used only to perform the verification, kept confidential, and deleted within 15 days (or immediately on request).
When you create an account (email sign-in link) we collect your email address, and a password hash if you choose to set one. When you subscribe to Tender Monitoring we also collect your bidding sectors and keywords, and — for the Pro eligibility-screening tier — the company credentials you enter (head-office region, company size, licenses and registrations, track record, grades), used only for eligibility screening.
This site is served as static pages; we do not use advertising trackers, and apart from the essential cookies that keep you signed in to your account, the site sets no cookies of its own. Our hosting provider may keep standard server logs for security and reliability. The contact and verification forms use Cloudflare Turnstile to block spam — Cloudflare runs a lightweight challenge to confirm you are human and does not use it to track you across sites.
To understand how the site is used, we also keep minimal, cookieless visit statistics on Sizlon’s own server: page path, page language, referring page, how far the page was scrolled, and time on page. These records contain no name, account, or cookie; the IP address is not stored — visits are counted with a hash that changes daily and cannot be linked across days — and browsers that send “Do Not Track” are excluded.
How we use it
We use your information to respond to your inquiry, provide the information you asked for, follow up about a possible deployment, and to manage your account and provide and bill the services you sign up for (tender alerts, eligibility screening, verification). Your account is the integrated Sizlon account across the services Sizlon operates (Miriboa and the customer portal) — the same credentials sign you in to each. We do not sell personal information.
Product data
Licensed Sizlon software is deployed on-prem or connected, under your control — data it extracts or processes stays in your environment, and Sizlon does not access it except where a support engagement expressly requires it and you have authorized it.
For vendor-operated services such as Miriboa, the documents you submit are used only to perform the requested verification, are not shared with third parties, and are retained and deleted according to the engagement agreement (including any NDA).
Service providers and international transfer
We use a small number of service providers to operate this site and handle inquiries; their servers may be located outside Korea, primarily in the United States. GitHub, Inc. hosts this website (GitHub Pages; standard server logs). Contact-form submissions and visit statistics are stored on Sizlon’s own server; Google LLC relays the notification email about new inquiries (Gmail). Cloudflare, Inc. provides the Turnstile anti-spam check. Toss Payments Co., Ltd. (Korea) processes payments for credit purchases and subscriptions; card details are held by Toss Payments, not by Sizlon.
Each provider processes personal information only to deliver its service and is bound by its own data-protection commitments. Beyond these providers, we share personal information only where required by law.
Retention
Account details (email, password hash) are kept until you delete your account; monitoring-subscription details (sectors, keywords, eligibility profile) are deleted without undue delay after you unsubscribe. We keep contact and inquiry records for up to three years from receipt, then delete them without undue delay. Records related to a paid verification — including the business registration number and billing details — are kept for five years where tax and e-commerce law require, then deleted. Bid documents uploaded for verification are kept confidential and deleted within 15 days, or immediately at your request. Electronic files are deleted by irrecoverable means.
Security
We apply reasonable technical and organizational measures to protect the information we hold. No method of transmission or storage is completely secure.
Your rights
Subject to applicable law — including the Personal Information Protection Act (PIPA) of the Republic of Korea — you may request access to, correction of, or deletion of your personal information. Email hello@sizlon.io to exercise these rights; we respond without undue delay.
Privacy officer
Sizlon’s privacy officer (개인정보 보호책임자) under Korean law is Kwangyeon Lee (CEO) · hello@sizlon.io — the contact for any privacy inquiry, complaint, or request for remedy.
If a matter is not resolved, you may seek help from Korea’s Personal Information Dispute Mediation Committee (www.kopico.go.kr · 1833-6972) or the KISA Privacy Incident Report Center (privacy.kisa.or.kr · 118).
Changes
We may update this policy; material changes are announced on this page at least seven days before they take effect. The current version is the one on this page, dated above.
