Privacy

Read how hzkjn.app handles local state, network requests, and visitor data.

Prelaunch privacy information for project discussions and nonbinding demonstrations. Ordinary public routes need no account. This site sets no cookies and uses no analytics. Catalog keeps temporary edits in this browser tab. When you request or verify a sign-in code, save or reopen a draft, submit an inquiry, or link a guest inquiry after verification, the site sends the information needed for that action to its server.

  • hzkjn.widgets.v1Local storage for widget visibility, size, and grid position. It remains until Clear Site Preferences removes it.
  • hzkjn.site-preferences.v1Local storage for motion, transparency, and restore-session choices. It remains until Clear Site Preferences removes it.
  • hzkjn.guide-dismissed.v1Local storage records only that the first-visit guide was dismissed. It remains until Clear Site Preferences removes it.
  • hzkjn.window-session.v1Session storage for open route windows and their layout in this tab. It ends with the tab or when Reset Desktop Layout removes it.
  • hzkjn.catalog-workspace.v1Session storage for temporary Catalog sample snapshots, component comments, configuration, notes, and saved Lead references in this tab. It ends with the tab or when the Catalog work is discarded.
  • hzkjn.catalog-auth.v1Session storage for the customer account and session identifiers used to verify Catalog save and inquiry actions. It ends with the tab or sign-out.
  • hzkjn.catalog-guest-claim.v1Session storage for the one-time guest inquiry claim token until magic-code sign-in links the Lead to the verified account. It ends after claim, claim expiry, discard, or the tab closing.
  • hzkjn.catalog-dirty.v1Session storage identifies which temporary Catalog sample snapshots have unsaved changes so leaving the route can offer Save or Discard. It ends when those changes are saved, discarded, or the tab closes.
  • Site and preview filesOn a route load, the browser requests static HTML, CSS, JavaScript, the PWA manifest, service worker, favicons, and original HZKJN assets from hzkjn.app. A link-preview client can request the public social image.
  • Offline cache updatesPWA setup, app updates, or visitor-triggered recovery requests allowlisted public routes, application files, the offline fallback, manifest, and original HZKJN app icons from hzkjn.app.
  • Docs navigationAn ordinary browser request to docs.hzkjn.app starts only when you open Docs.
  • Demo navigationAn ordinary browser request to demo.hzkjn.app or one selected demo host starts only when you open Live demos or a listed application.
  • Client sign-in navigationAn ordinary browser request to client.hzkjn.app starts only when you open Client sign in.
  • Catalog customer magic-code sign-inCatalog sends an email address to a same-origin server route only when you request a magic code. The browser sends the one-time challenge identifier and six-digit code only when you choose Verify. The server verifies the code and returns account and session identifiers; service credentials never enter the browser.
  • Catalog account creationWhen you choose Create account, Catalog sends your email address through a same-origin server route. The server derives a salted source hash for abuse limits and does not store the raw source address in the account verification record. It stores a time-limited magic-code challenge and requests email delivery of the code to that address. The browser sends the code to the server only when you choose Verify.
  • Catalog draft and inquiryCatalog sends normalized edits, component comments, general notes, configuration, and public estimate context to a same-origin server route only when a visitor saves, lists drafts, or submits. Signed-in actions include the customer session reference. Guest submissions include contact details, preferred channel, consent to contact, and a salted source hash for abuse limits. The server stores the draft or inquiry for authorized HZKJN staff.
  • No other runtime service requestSearch, Jakarta time, widgets, windows, the guide, Preferences, anonymous Catalog editing, sample switching, and local price calculation do not send data to a HZKJN platform service.
  • CookiesThe production cookie allowlist is empty. The site sets no essential or nonessential cookie.
  • Analytics eventsThe production analytics event allowlist is empty. No event is collected or sent.
  • Analytics exclusionsSearch text, pointer paths, window coordinates, contact text, stable visitor identity, Catalog text edits, Catalog comments, and Catalog notes cannot enter analytics.
  • Service-worker cachesThe production service-worker cache allowlist contains only hzkjn-marketing-2026.08.2. Privacy and Terms use the network or show the offline-unavailable state; cached public pages state when they can be out of date. Clear offline data in Preferences removes this cache safely.
  • Guest inquiriesAn inquiry includes the contact details, preferred channel, consent, selected sample, edits, comments, notes, configuration, and estimate context you submit. Consent is recorded with the inquiry. Submission does not reserve an account or verify your identity. Authorized HZKJN staff can review the inquiry to discuss scope.
  • Verified accessSign-in uses an emailed one-time code. Account and session records support verified access. Abuse prevention uses a salted source identifier. A temporary claim token can link a guest inquiry to the verified account under account-access checks. Expiry of a code or claim token does not itself delete an inquiry or account record.
  • Server recordsClearing site preferences or closing a browser tab does not delete information already submitted to the server. Server retention periods, processing locations, and request procedures require final confirmation before accepting a real engagement.
  • Privacy questionsEmail hello@hzkjn.app with questions about information you have shared. Do not include passwords or payment credentials. This contact address does not establish a retention deadline or a deletion guarantee.
