Privacy Policy

Privacy is central to MyDataFixer. This policy explains, in plain language, what happens to your files and what little information we handle.

Last updated: 14 November 2026

Summary

  • Your spreadsheets are opened and processed by your web browser, on your device.
  • The contents of your files are not uploaded to MyDataFixer servers and are not sent to third parties.
  • We do not require an account and do not ask for your name or email address to use the tools.
  • We do not sell personal information.

Files you open with MyDataFixer

When you choose a file, your browser reads it into the memory of the open tab. The checks, cleaning operations and conversions run as JavaScript on your device. When you download a result, the new file is created locally by your browser. Closing or reloading the tab releases the file from memory.

Changes you make (fixes, repairs and edited cells) are also kept only in the memory of that tab until you download the result; nothing is saved anywhere else. When one MyDataFixer page passes your file to another (for example “Check and repair in the CSV Validator” on the CSV to Excel page), the file stays in the same tab's memory and is not uploaded.

Your original file is never modified. Formulas inside spreadsheets are treated as text and are never executed as code.

Information stored in your browser

If you switch between light and dark mode, your choice is saved in your browser's local storage so the site remembers it. This value never leaves your device. MyDataFixer does not set advertising or tracking cookies.

Server and hosting logs

Like any website, the servers that deliver MyDataFixer's pages may automatically record standard technical information about requests, such as IP address, browser type, the page requested and the time of the request. These logs are used to keep the service secure and working, and they never contain the contents of your spreadsheets, because those are not sent to the server.

Analytics

MyDataFixer does not currently use analytics. If privacy-friendly usage statistics are added in the future (for example, counting how often a tool is opened), they will never include spreadsheet contents or information taken from your files, and this policy will be updated before that happens.

Emails you send us

If you contact us by email, we receive the message and your email address and use them only to respond. Please do not send confidential spreadsheets or personal data.

Children

MyDataFixer is a general-purpose tool and does not knowingly collect personal information from children.

Changes to this policy

If we change how MyDataFixer handles data, we will update this page and the date above. Questions can be sent through our contact page.
