Your EPUB is temporary scan input.
EPUB Fixer needs the file to run EPUBCheck and inspect package paths. The report uses paths and error summaries, not manuscript text.

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.
Scan metadata is kept separate from book content.
Service logs can include a request ID, file-size range, scan status, error class, issue counts, and feedback choices. They do not store manuscript text.
Emails and feedback are used for report follow-up.
If you save an email or submit feedback, it is tied to the Report ID, issue type, and retry result so EPUB Fixer can respond to that scan or review repeated error patterns. Do not include passwords, payment details, or manuscript text.
The site does not use browser tracking cookies.
EPUB Fixer does not use advertising or analytics cookies on this site.
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.
Uploaded files are temporary scan input.
Uploaded EPUBs, generated repaired files, and temporary scan artifacts expire after 24 hours. The result page can remove the uploaded EPUB and generated files earlier when the delete action is available.
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. Keep any copied report summary first.
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 safe 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 hello@epub-fixer.com 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.
