Keep your personal documents out of everyday Photos.

The private-reference album many people already have

A photo library often becomes a filing cabinet by accident. A picture of a passport before a trip. A driver’s licence copied for a form. A screenshot of account details so you can find them later. Perhaps even a photo of a handwritten password list.

These images are easy to capture and easy to lose among thousands of ordinary photos. They also deserve a different level of privacy from your lunch, your dog or last weekend’s beach pictures. An encrypted reference vault gives them a deliberate home.

Organise by the job, not by the camera date

Create a dedicated collection for personal reference documents. Keep travel documents together if that is how you use them, and use a different vault for other private files when separating them is helpful.

CalcLock uses exact equations to open separate vaults. You do not have to scroll through a master list of private collections from the calculator. Enter the equation for the collection you want and press equals twice to open it.

Start with the few documents you genuinely need on hand. Check that each image is readable, complete and current. A blurry passport number or cropped expiry date will not become more useful because it is encrypted.

Passport and ID copies are references, not replacements

A digital copy can help you find details when completing a form or contacting an issuing authority. It does not replace a physical passport at a border or establish that an organisation will accept a photographed identity document.

Keep the original document safe and follow the recipient’s actual verification process. Send identity documents only through a verified destination and only when needed. A request in an unexpected text message is not proof that a passport copy should be sent.

If you retain a copy for a specific application, check whether you still need it after that task is finished. Keep fewer unnecessary copies, rather than accumulating every document indefinitely.

Bank details and handwritten passwords need different treatment

A screenshot of bank account details may be useful when you need to provide payment instructions. Check it against the bank’s own app before relying on it, particularly if the account has changed. An old screenshot is a reference, not a live account record.

A photo of handwritten passwords is more sensitive: it may expose access to several accounts at once. A dedicated password manager is usually the better long-term tool for passwords, because it can generate unique credentials and autofill them. If you already have a photographed list, moving the reference out of ordinary Photos reduces casual exposure while you organise a better system.

Do not keep a password hint that gives away your vault equation alongside the documents it protects. Choose an equation that someone cannot guess from your birthday, licence or passport.

Check every place the original might remain

Import a small group into CalcLock, open the files, then close and reopen the vault to confirm access. Its files and filenames are encrypted with AES-256-GCM; the equation and a device-held secret contribute to the vault key.

The import does not remove the original from Photos, Files, email or messages. Review those copies separately. Remember that deleting a photo from an iCloud Photos library can remove it from other synced devices too, and deleted images may remain in Recently Deleted.

Keep a verified independent recovery route for documents you cannot afford to lose. The issuing authority or bank remains the source of truth; a phone vault should not be the only way you can find essential account or identity information.

A simpler everyday habit

When a sensitive reference arrives, decide whether you need to retain it. If you do, put the checked copy in its intended vault, review the original’s location and remove outdated copies when appropriate. That short routine is more useful than trying to hide an entire cluttered camera roll.

Use CalcLock’s instructions for creating and opening vaults, and the backup guide for your installed version’s recovery options.
