The filing cabinet that fits in a pocket

Store Important Documents on iPhone

Keep policies, warranties, receipts, and other records in a document library on iPhone, with folders, tags, and search for recognized text.

Short answer

Scan paper or import a PDF, give the file a descriptive name, and add a folder and tags. Search by name or recognized text in the ScanLens library. Enable backup and check that it completes before relying on recovery.

Organize document copies in one library

Keep each multi-page document in one PDF. Name it by date and subject, then file it in a folder such as Home, Health, or Taxes. This keeps related pages together and separates records from everyday photos.

Get every important document into one place

  1. Scan the paper you have. IDs, insurance policies, warranties, receipts for anything expensive, the lease, medical letters, tax papers. The scanner squares the page and cleans it up as you go — your phone is the scanner.
  2. Import what is already digital. PDFs from Mail and Files come in as documents; photos of documents can be pulled in from the camera roll and cleaned up on the way.
  3. Give each file a descriptive name with its date and subject, such as 2026-10-07_Boiler-Warranty.pdf.
  4. File into folders and add tags. Folders for the big categories — home, health, car, taxes — and tags for what cuts across them: a receipt can sit in home and carry a 2026-taxes tag at the same time.
  5. Mark the few you reach for constantly. Favorites keep the insurance card and the kids' school forms one tap away.

Search recognized text in your document library

Search matches names and text recognized in documents in the ScanLens library. If a word is missing from the results, check the scan’s legibility and its OCR output. Recognition does not guarantee that every word will be indexed correctly.

For text search outside the library: searchable PDFs.

Keep the archive safe

Back it up to iCloud

Enable iCloud Backup, then check that the library backup finishes. A completed backup is needed to restore documents on another iPhone using the same iCloud account. scanning to iCloud.

Lock the app

App Lock puts Face ID in front of the whole library, so handing someone your phone does not mean handing them your tax history. More in document security on iPhone.

Protect what you send

When a stored document has to travel — proof of address to a landlord, an ID to a bank — password-protect the copy and keep the original where it was.

Deleted is recoverable

Removed documents sit in the Recycle Bin before they are gone for good, so one wrong swipe does not erase the deed to the house.

What belongs in the archive — and what stays on paper

Start with records you regularly need: identification copies, insurance policies, warranties and receipts, leases, medical letters, and tax records.

Keep the paper originals of documents whose physical form carries legal weight — passports, birth and marriage certificates, notarized deeds, wet-ink wills. The scan is your fast copy for everyday use; the original goes somewhere fireproof. The full keep-or-shred breakdown is in which documents to keep as originals, and the room-by-room process in digitizing paper documents.

Keep an additional copy in cloud storage

Export a copy to the cloud folder you choose and open it after the upload finishes. export to a cloud folder.

Frequently asked questions

What is the best way to store important documents on a phone?

Scan paper or import a PDF, give the file a descriptive name, and add a folder and tags. Search by name or recognized text in the ScanLens library. Enable backup and check that it completes before relying on recovery.

Can I find a document by what is written in it?

Search matches names and text recognized in documents in the ScanLens library. If a word is missing from the results, check the scan’s legibility and its OCR output. Recognition does not guarantee that every word will be indexed correctly.

Is it safe to keep IDs and financial documents on my iPhone?

The scans live on the device, and reading them requires unlocking the phone; App Lock adds Face ID in front of the library itself. Backup, if you enable it, goes to your own iCloud account. When a sensitive document has to be sent somewhere, password-protect the copy you send.

What happens to my documents if I lose my phone?

If a library backup completed before the phone was lost, restore it on an iPhone using the same iCloud account. Files stored only on the lost device may be unrecoverable. Check backup status while you still have access to the library.

Should I still keep the paper originals?

A scan is a convenient working copy, not a universal replacement for the original. Ask the issuer or receiving authority which documents must remain on paper before disposing of them.

Is ScanLens free for storing documents?

ScanLens is a free app: scanning, importing, folders, tags, favorites, and search by name and by document text are all part of it. iCloud Backup of the library is free as well and off until you switch it on.
