Operator and contact
ChapterTidy is operated by Cloud Lu. For questions about the service or how files are handled, contact [email protected].
Start with the file format and exact error wording rather than attaching your full manuscript. Do not send private manuscript content or a raw report unless it is needed and you have agreed on a suitable way to share it.
What ChapterTidy is for
ChapterTidy is a browser-based manuscript checking and repair tool. Its focus is existing DOCX and EPUB files with problems such as contents links, chapter structure or paragraph formatting. Inspect the findings, choose supported changes, then review the exported file.
It is not a publishing platform. Imports such as PDF may require conversion or OCR and produce drafts that must be compared with the source. A successful check does not guarantee visual fidelity, accessibility, acceptance by KDP or another platform, or publication readiness.
What the checks can tell you
The report distinguishes checks for text, images, chapter structure, navigation and file packaging. EPUB reports show whether EPUBCheck passed, failed or did not run. A valid file can still have a wrong destination, an awkward layout or another issue that needs a person to review it in the intended reader.
The guides link to file standards and editor or platform documentation, and describe limits alongside the steps. The public DOCX and EPUB samples are original practice files, not customer manuscripts or evidence of a success rate. Keep your source file and inspect the actual export before publishing.
How to read the evidence in our guides
The repair guides are published under the ChapterTidy name. Cloud Lu operates the service. This identifies publishing responsibility; it is not a claim of independent certification or a professional credential.
References beside a section point to the standard, editor or platform documentation used for its external requirements. Individual author discussions are labelled separately: they show a reported problem, not its frequency or proof that a platform is at fault. ChapterTidy workflow descriptions and original sample results are identified as product-specific evidence.
A controlled sample establishes only the cases and checks described. Where a test did not run, or a reader, format or publishing platform was not tested, the guide states that limit. The EPUBCheck evidence download contains selected results from an original practice file, with its hash, version, mutations and diagnostic locations. It is not a customer report or a success rate.
The updated date records changes to the guide. It does not promise that every linked source or every product behavior was retested on that date. For a possible correction, send the guide URL, the section and the exact issue to the contact above, without private manuscript content.
Where uploaded files are processed
Using the workspace sends the selected file to the ChapterTidy server. Processing is not confined to your device. The service stores the uploaded source and working files so you can inspect revisions, repairs, previews and exports during the retention period. Scanned PDFs use server-side OCR.
Reading a guide or this page does not upload a manuscript. The sample buttons upload the included practice file only when you click them. Upload only material you are permitted to send to the service; try a sample first if you are deciding whether the workflow fits your book.
File expiry and deletion
The default file retention period is 24 hours from upload. The workspace shows the expiry time. You can use Delete to revoke access sooner and remove the manuscript, its versions and exports. Deletion may finish through background cleanup rather than immediately.
File removal is not the same as erasing every operational record. Technical records such as file hashes and task status can remain after file content is removed. Do not treat the file expiry period as a promise that every log or service record is deleted at the same time. Keep your own source and download any output you want to retain before the workspace copy expires.
Anonymous sessions and browser preferences
The workspace uses an anonymous session cookie to associate requests with your manuscripts. It is not an account login or a way to recover files on another device. Removing browser session data can prevent you from returning to a manuscript, even before its file expiry time.
The interface remembers your chosen language in browser storage. This preference is separate from the language of the manuscript. The workspace has 12 interface languages; the repair guides and this page are currently in English.
Website analytics and infrastructure
The public website uses Cloudflare for delivery and protection, and Cloudflare Web Analytics for page and performance measurements. Browsing the site sends page addresses and performance telemetry to Cloudflare. This is not a zero-data-collection service.
The analytics measurements are different from manuscript processing. This page does not set a separate retention period for Cloudflare or other infrastructure records. Avoid placing confidential manuscript text or personal details in page URLs.
Try the workflow with a practice file
You can download either practice file without uploading your own writing. To run a sample through the checker, open the workspace and select the matching sample button. The checks help you decide what to review; you stay responsible for reviewing and publishing your work.
