Store It or Shred It? A Luxembourg Guide to Handling Sensitive Documents Securely

A box of old bank statements, expired passports, payslips and a dead laptop sits in your hallway. Some of it you are legally required to keep. Some of it is an identity-theft risk just sitting there. So which is which, and what should you actually do with each pile? Here is a practical Luxembourg guide to deciding what to store and what to securely destroy.

Why keeping sensitive documents at home is a real risk

Paperwork and old devices feel harmless in a drawer, but at home they are exposed to the things you cannot plan for: burglary, fire, water damage, and simple loss. Worse, a single discarded bank statement or an old hard drive in a cupboard is enough for identity fraud. The safest position is simple: keep only what you need, store it properly, and destroy the rest beyond recovery.

What you should keep: and store securely

Some documents have to be retained, often for years: tax records, employment and salary documents, property and mortgage paperwork, insurance policies, and official certificates. These should not live in a shoebox at home. Off-site secure storage keeps them safe from theft, fire and water while staying accessible when you need them. Storagelux can store sealed document boxes door-to-door, see Storagelux storage for how pickup and return work.

What you should destroy: and why deletion is not enough

Anything you are not required to keep and that carries personal or financial data should be destroyed, not binned. That includes old statements, expired ID, superseded contracts, and, critically: retired hard drives, phones, USB sticks and laptops. Deleting files or "wiping" a drive does not reliably remove the data; fragments are routinely recovered from devices sold or thrown away. Physical destruction is the only way to be certain. For paper, that means professional document shredding to ISO/IEC 21964 (formerly DIN 66399) P-4, not an office strip-cutter.

How long should you keep documents in Luxembourg?

Retention periods vary by document type and situation, for example, businesses are generally expected to keep accounting and tax records for several years, while individuals often keep tax and property paperwork for a similar period. Rules change and depend on your circumstances, so treat this as general guidance rather than legal advice and confirm specifics for your situation. The principle that always holds: once a document is genuinely past its useful and required life, do not just throw it away, destroy it securely.

The secure way to dispose: on-site destruction with a certificate

Lëtzclean Data destroys drives, media and sensitive documents on-site at your premises, so nothing sensitive ever leaves your control intact. You get a documented chain of custody and a certificate of destruction for your records, which matters for GDPR accountability and for your own peace of mind. For businesses, this closes the loop that a shredder bin or a "we will wipe it later" promise leaves open.
