1. Introduction & Overview

At DesignoFly Studio, we understand that authors, independent publishers, researchers, and educators work with valuable intellectual property, unreleased manuscripts, and copyrighted literary material. This Privacy Policy outlines the privacy and data handling practices for Piludi – Ebook Converter (“the Application”, “we”, “our”, or “us”), a publication-grade Windows desktop eBook workstation created by KS Ajay, founder of DesignoFly.

Piludi – Ebook Converter enables users to convert, package, and validate eBooks across major digital reading standards—including EPUB 2/3, Amazon Kindle AZW3 and MOBI, Microsoft Word (DOCX), PDF, FictionBook 2 (FB2), HTML, and Plain Text—while editing Dublin Core metadata, structuring hierarchical Tables of Contents (TOC), and previewing book chapters.

By downloading, installing, or using Piludi – Ebook Converter, you agree to the privacy practices outlined in this policy.

2. Privacy by Design (Core Principles)

  • 100% Local On-Device Execution: All manuscript parsing, text restructuring, XHTML formatting, font embedding, image scaling, and eBook archive packaging occur entirely on your local Windows PC.
  • Strict Intellectual Property & Manuscript Confidentiality: Your unpublished books, novel drafts, proprietary illustrations, poetry, research papers, and cover art are never uploaded to, transmitted across, or stored on remote cloud servers.
  • Zero Telemetry or Data Collection: We do not collect, monitor, or transmit any analytics, crash logs, or user behavioral telemetry.
  • No Accounts or Subscriptions: The application does not require an account, email sign-up, or remote login to access any of its features.
  • Fully Operational Offline: The software functions completely without an active internet connection.

3. Information We Do NOT Collect

Piludi – Ebook Converter operates strictly as a self-contained offline utility. We do not collect, monitor, store, or share:

  • Personal Identifiable Information (PII): We do not collect your real name, email address, physical location, IP address, or payment details.
  • Manuscript Content & Intellectual Property: We never read, inspect, analyze, copy, or transmit the text, chapters, poetry, storylines, or proprietary ideas inside your books.
  • Book Metadata & ISBNs: Any metadata you enter (Book Title, Author Name, Pen Name, Publisher, ISBN number, Copyright notices, or Book Description) is written strictly into the local eBook files on your hard drive and is never transmitted to us.
  • Cover Art & Media Assets: Illustrations, diagrams, charts, and cover images remain strictly on your local PC.
  • Device Identifiers: We do not record hardware MAC addresses, motherboard serials, or digital system fingerprints.
  • Usage Statistics: We do not monitor how many books you convert, which formats you choose, or your conversion processing times.

4. How the Application Operates (Local Permissions)

To package and validate publication-ready eBooks on Windows, Piludi – Ebook Converter utilizes standard local file system access:

1. Local File System Reading: When you import files via drag-and-drop or the file picker dialog, the application reads the source document (EPUB, PDF, DOCX, etc.) locally from your storage drive to parse chapters and extract assets.

2. Local File System Writing: Converted eBook packages (such as .epub, .azw3, .mobi, or .docx) are written strictly to the local directory location you specify. The application never alters or deletes your original source manuscripts.

3. Local Temporary Memory Buffer: During EPUB archive assembly, ZIP packaging, or Kindle format compilation, temporary working folders are created in your local Windows temp directory (AppData\Local\Temp). These files reside strictly on your PC and are automatically destroyed upon task completion.

5. Third-Party Services & Store Distribution

  • Microsoft Store: When distributed via the Microsoft Store, download delivery, installation, and automated store updates are governed by the Microsoft Privacy Statement. DesignoFly Studio does not receive or store your Microsoft account credentials or billing records.
  • Zero External Dependencies: The application contains no third-party tracking scripts, advertising networks, or external cloud analytics endpoints.

Because Piludi – Ebook Converter operates 100% locally on your computer with zero external data connections:

  • You retain 100% full, uncompromised ownership and copyright over every manuscript, cover graphic, and converted file.
  • Your unreleased books are completely protected against unauthorized digital leaks, cloud data breaches, or third-party AI training scraping.

7. Children’s Privacy

Piludi – Ebook Converter does not collect personal information from any user, including children under the age of 13. The application is completely safe, offline, and suitable for all age groups.

8. Changes to This Privacy Policy

We may periodically update this Privacy Policy to reflect product improvements or regulatory standards. Any changes will be published with an updated “Last Updated” date at the top of this document and on our official studio website.
