Your EPUB files are deleted after 24 hours.
EPUB Fixer needs the file on the server to run EPUBCheck and inspect package paths. File deletion, scan metadata, report links, feedback, and saved emails have separate lifecycles explained below.

What the scan uses
What the scanner sees after upload.
Your EPUB is uploaded to the server for this scan.
EPUB Fixer is not a local-only browser checker. The server needs the EPUB package so it can run EPUBCheck, open container.xml, find the OPF file, follow navigation links, compare image and stylesheet paths, and recheck any repaired EPUB before a download appears.
The report shows paths and error summaries.
The report is built for troubleshooting. It shows affected EPUB paths, issue types, repair decisions, original validator messages, and next steps. It does not display chapter text, manuscript paragraphs, or book prose in the report view.
Uploaded and repaired files are deleted after 24 hours.
The original EPUB, generated repaired EPUB, extracted package files, and temporary scan artifacts are deleted automatically after their 24-hour expiry. The result page stops providing report and download access at expiry. You can delete the files sooner from the result page.
File deletion and scan metadata have different lifecycles.
After files are deleted or expire, EPUB Fixer keeps the Report ID, original filename, file size, scan status, error classes, affected paths, validator messages, event history, feedback, and saved email requests for report follow-up and aggregate product analysis. These records are not covered by the 24-hour file deletion. Email [email protected] with the Report ID to request their deletion.
Anyone with the report link can open it while it is active.
Result pages do not require an account. Anyone who has the full result link can view that report until its files expire or are deleted. Share the link only with an editor, formatter, or other person you trust to help with this EPUB.
No advertising cookies; one session ID connects product events.
EPUB Fixer stores one random visit ID in browser sessionStorage for the current tab session. It connects page views, uploads, scans, report views, downloads, and feedback without using advertising or analytics cookies. The browser value ends with the tab session; recorded events remain part of scan metadata until you request deletion.
Emails and feedback are used for report follow-up.
If you save an email or submit feedback, it stays tied to the Report ID, issue type, and retry result until you ask for deletion. EPUB Fixer uses it to respond to that report or review repeated error patterns, not for general marketing. Do not include passwords, payment details, or manuscript text.
Service providers handle technical scan data.
Hosting, database, logging, and email providers may handle uploaded files, report metadata, logs, feedback, or email requests only so the scan works, support requests can be answered, or abuse can be blocked.
The scan does not train models or fetch remote book resources.
EPUB Fixer does not use uploaded EPUBs, manuscript content, scan reports, or feedback to train models. It also does not load remote URLs referenced inside the EPUB package.
What you can do
How to stay in control of the upload.
Remove the upload from the result page.
Use the delete action if you want the uploaded EPUB, repaired file, and temporary scan files removed before automatic expiry. This also ends report access. It does not delete the separate scan metadata or saved follow-up records described above; email with the Report ID if you want those records deleted too.
Use only files you are allowed to test.
If you are not allowed to upload the EPUB for validation, use your source tool or a local workflow instead.
Choose another tool if you need offline-only checking.
Use a local EPUBCheck, Sigil, calibre, or an offline fixer if the EPUB cannot leave your device. This scanner runs server-side because it needs the packaged EPUB to inspect paths, run validation, and revalidate deterministic repairs.
Keep support requests small.
Use the Report ID from Scan details, path, error code, or screenshot when asking for help. Full manuscript content is usually not needed.
Ask about your data by email.
Email [email protected] if you need access, correction, deletion, or a question about EPUB uploads, Report IDs, feedback, or saved email requests. Include the Report ID when the request is about a specific scan.
Use the same contact for EU, UK, or California privacy requests.
If privacy law gives you a right to access, delete, correct, restrict, or object to certain processing, use the contact email above. EPUB Fixer does not sell uploaded EPUBs, scan reports, email addresses, or feedback.
