Does DiffFind Store or Upload the Text and Files I Compare?

Updated

DiffFind's own comparison page states that your text is sent to the DiffFind app only when you click "Find difference," and that nothing is stored on that page. That covers the on-page text compare tool. It does not, by itself, describe a full retention or deletion policy for the app, for uploaded files, or for AI analysis — so if you are comparing contracts, invoices, or other sensitive material, treat the page notice as a starting point and confirm the current details in DiffFind's official privacy documentation before relying on it.

What the page actually says

The text compare section carries this notice:

  • Your text goes to the DiffFind app only when you click "Find difference."
  • Nothing is stored on this page.

Two things follow from that wording. First, typing or pasting into the before/after boxes does not transmit anything by itself — the send happens on the button click. Second, the "nothing is stored" claim is scoped to this page, meaning the public comparison page, not necessarily every part of the service.

Why the distinction matters

DiffFind is built for documents where changes carry consequences — the site names contracts, invoices, budgets, and policy documents as business use cases, and resumes, emails, and articles as everyday ones. Those are exactly the files people hesitate to paste into an unknown tool.

The page notice answers the most immediate worry: that merely loading the page or typing into it leaks content. It does not answer the next questions:

  • How long is submitted text or a file retained in the app after comparison?
  • Are uploaded PDFs and Excel workbooks handled the same way as pasted text?
  • What happens to content when you turn on the optional AI analysis, which the site says checks cited facts against your source documents?
  • Do API, cURL, or URL-based comparisons follow the same rules?

None of these are specified in the material available here.

Practical way to decide

Your situation Reasonable approach
Comparing a public draft, sample text, or non-sensitive snippet The on-page notice is likely sufficient for a quick check
Comparing a contract, invoice, or personal document Read DiffFind's official privacy/security page first and confirm retention and deletion terms
Using AI analysis on confidential material Confirm separately how source documents are handled during AI processing
Automating via API or cURL Check the developer/API documentation for its own data-handling terms

If the official documentation does not state a retention period or deletion behavior, do not assume content is deleted immediately just because the page says nothing is stored there — those are different claims.

The short version

  • Typing/pasting alone: nothing is sent until you click "Find difference," per the page.
  • The comparison page: states it stores nothing.
  • The app, uploaded files, AI analysis, and API: not covered by that notice; verify with DiffFind directly.
  • Sensitive documents: confirm the current policy before uploading, not after.
