1. What Are Cookies and Local Storage?

Cookies are small data files placed on your computer, smartphone, or tablet when you visit websites. Local Storage (HTML5 Web Storage) is a standard browser mechanism allowing web applications to store data persistently on the client side with higher capacity and without sending tokens with every HTTP request.

Editorial3D uses these technologies solely to authenticate publisher accounts, remember your interface theme preferences, and save reading state so flipbook readers do not get re-prompted by lead capture gates they have already completed.

2. How We Use Storage

We classify our browser storage into three functional categories:

  • Strictly Necessary: Essential for signing in, maintaining secure publisher sessions, and processing checkout payments. The Service cannot function properly without these tokens.
  • Preferences & Aesthetics: Used to remember your selected theme (Dark Mode or Light Mode) and viewer zoom preferences across browser tabs.
  • Viewer & Reading Functionality: Used in the 3D flipbook viewer to remember unlocked lead gates and reader sound settings (e.g. muting page-turn audio).
Zero Ad Tracking: Editorial3D does NOT use advertising cookies, marketing pixels (such as Facebook Pixel or TikTok trackers), or cross-site tracking scripts.

3. Detailed Storage Breakdown

The table below provides a comprehensive list of the cookies and local storage keys used across our services:

Name / Key Category Purpose Storage Type Duration
__session Strictly Necessary Secures publisher authentication and API authorization via Clerk. HTTP Cookie Session / 30 Days
e3d-theme Preferences Stores selected Dark or Light theme to prevent theme flashing on reload. Local Storage Persistent (1 Year)
e3d_gate_{slug} Functional Remembers that a reader has submitted a lead gate for a specific flipbook. Local Storage Persistent (90 Days)
e3d_sound_muted Preferences Stores whether the reader has muted 3D page curl audio effects. Local Storage Persistent (1 Year)
__stripe_mid Strictly Necessary Fraud detection and secure payment authorization by Stripe. HTTP Cookie 1 Year

4. Third-Party Services

When you sign in or complete a purchase, our infrastructure partners (such as Clerk for authentication and Stripe for payment processing) may set essential security and anti-fraud cookies. These cookies are strictly regulated by their respective privacy policies and are necessary to ensure secure account management and PCI-DSS compliant checkout.

5. Managing Your Storage & Cookie Preferences

Most web browsers automatically accept cookies, but you can modify your browser settings to decline cookies or clear your local storage at any time. If you choose to block strictly necessary cookies, you will not be able to log in to your Editorial3D publishing dashboard.
