Works with the files you already have

How it works

Three steps. Zero uploads.

Elisio does all of its work on your Mac. Drop a document in, check what it found, and save a clean copy.

  1. 1

    Drop your document

    Drag in a PDF, scan, photo or Office file. Your original is never changed.

  2. 2

    Review what it found

    Names, SSNs, account numbers and addresses are highlighted. Keep, remove or add your own.

    Personal details highlighted for review
  3. 3

    Save, verified

    Elisio scans the result again before saving. If anything can still be read, it won't save.

No network access. Not even once.

The Elisio app has no permission to connect to the internet. It can't upload, sync, track or phone home, because macOS won't let it. Your documents physically cannot leave your Mac through Elisio.

  • ✓ No internet permission
  • ✓ No account or sign-in
  • ✓ No analytics or tracking

Features

Everything you need to share safely

  • Finds personal details

    Names, SSNs, account and routing numbers, addresses, dates of birth.

  • Reads scans & photos

    Text recognition runs on your Mac, so scanned and photographed pages work too.

  • Knows tax forms

    Understands W-2 and 1040 boxes by their labels, not just patterns.

  • Checks before saving

    Re-scans the output and blocks the save if anything is still readable.

  • Remembers your choices

    The Dictionary learns what to always redact and what to leave alone.

  • Never touches originals

    Your source file stays exactly as it was. Elisio saves a new copy.

  • Private by design

    No network, no account, temporary files deleted automatically.

  • No subscription

    Free to download. Pro is a one-time purchase, no monthly fee.

Privacy

Your documents are none of our business

Elisio was built so that the safest choice is the only choice. There is nothing to opt out of, because nothing is collected in the first place.

Everything happens on your Mac. Nothing is ever sent anywhere.

Read how Elisio protects your privacy ›

  • No uploads

    The app has no internet permission, so your files can't leave your Mac through Elisio.

  • No account

    No sign-up, no sign-in, no email address needed to use it.

  • No tracking

    No analytics, no crash reporters, no ads. Not in the app, not on this website.

  • No logs of your data

    Elisio never writes the personal details it finds into logs or reports.

  • Originals untouched

    Your source file is never changed. Elisio saves a new, redacted copy.

  • Temporary files deleted

    Working files are removed when you save or cancel, and again at launch.

  • Dictionary stays local

    The words Elisio learns are stored encrypted, only on your Mac.

  • Proof before saving

    The result is checked again, and the save is blocked if anything is still readable.

Real redaction

A black box isn't redaction. Elisio removes the text underneath.

Many "redacted" PDFs still hide the original words under the black bars, ready to copy and paste. Elisio removes the content itself, then checks the saved file to prove it's gone.

✓ Verified clean · nothing left to find

Built for tax season

Send your W-2 to your landlord, lender or accountant without oversharing.

Elisio knows where the sensitive boxes are on US tax forms and bank statements, so you share the numbers that matter and nothing more.

FAQ

Questions, answered

Does Elisio upload my documents anywhere?

No. The app has no network access at all. Everything happens on your Mac, and macOS itself prevents Elisio from connecting to the internet.

Is it really redacted, or just covered?

Really redacted. Elisio removes the underlying text and images, then re-scans the saved file. If any redacted value can still be found, the save is blocked.

Which files does it support?

PDFs (including scans), PNG, JPEG, TXT and CSV for free. Word and Excel with Pro.

Is there a subscription?

No. Elisio is free to download, and Pro is a one-time purchase.

Is there an iPhone or iPad version?

Not yet. Elisio is for Mac first, and an iPhone and iPad version is planned.

What do I need to run it?

A Mac running macOS 26 or later.
