Privacy policy

3I Solution Inc. maintains this privacy policy under Article 30 of the Personal Information Protection Act of Korea to protect personal information and handle related concerns promptly.

1. Article 1 Purpose

   3I Solution Inc. (the “Company”) processes personal information only for the purposes below. If a purpose changes, we will notify you in advance and ask for consent again.

   • Website inquiries — to review and answer product, technical service, partnership and career inquiries
   • Vision-BMS service (conveyor belt damage monitoring and mobile app) — to authenticate customer staff and deliver equipment alerts

2. Article 2 Information we collect

   ① Website inquiries

   • Required: name (company), phone, email, message
   • Collected automatically: IP address and access time — to prevent automated (spam) submissions

   ② Vision-BMS console and mobile app

   • Account: user ID, password, display name, role
   • Notifications: the device push token — to deliver equipment alerts to that device
   • Collected automatically: access logs (time of access and actions taken)

   ③ Website visits

   • Collected automatically: IP address, time of access, pages visited, referring page, browser and device information — for visitor statistics and security monitoring

   The Company does not offer public sign-up. Vision-BMS accounts are issued by the Company to staff of contracted customers.

   The app does not collect location, contacts, photo library, address book or advertising identifiers. Equipment photographs are taken by on-site devices and do not identify individuals.

3. Article 3 Retention

   • Website inquiries: kept for 3 years after the inquiry is resolved, then destroyed without delay
   • Vision-BMS accounts: until the contract ends or the user asks for removal
   • Push tokens: deleted immediately when notifications are turned off or the user signs out
   • Damage records and evidence images: deleted automatically after 30 days
   • Website access logs: deleted automatically after 90 days (only statistics that cannot identify individuals, such as visits by country and date, are kept)

   Where other laws require retention, data is kept separately only for that period.

4. Article 4 Disclosure to third parties

   The Company does not provide personal information to third parties, except where specifically required by law.

5. Article 5 Outsourcing

   We outsource the following to operate the service.

   • Google Cloud (Google LLC) / Task: server operation and data storage / Location: Republic of Korea (Seoul region)
   • Expo (Expo, Inc., United States) / Task: relaying mobile push notifications / Data sent: device push token and alert text (belt name, damage type, position)

   Notifications pass through Expo to the device vendor’s push service (Apple APNs · Google FCM). The Company contractually requires processors to protect personal information and reviews their compliance.

6. Article 6 Destruction

   Information whose retention period has ended or whose purpose has been fulfilled is destroyed without delay. Electronic files are deleted irreversibly; printed material is shredded or incinerated.

7. Article 7 Your rights

   You may request access to, correction, deletion or suspension of processing of your personal information at any time. Contact contact@3isol.com and we will act without delay.

   App users can delete the push token immediately by turning notifications off or signing out in the app’s Settings.

   • Access to personal information is limited to the minimum number of people
   • Data in transit is encrypted (HTTPS)
