UnderKey for Families
Birth certificates, insurance policies, vaccination records, vehicle documents — every household accumulates dozens of important documents, and most live in a filing cabinet nobody has opened in years. UnderKey lets you store, organize, and track household documents on your phone, so you can find what you need in seconds instead of searching for hours.
Why families need organized document storage
Without a system, important documents end up scattered across drawers, emails, and photo galleries. This causes problems when:
- You need to prove something quickly. Your insurance claim is rejected because you can't find the policy number. You miss a renewal deadline because you forgot when your car insurance expires.
- Someone else in the family needs access. If your partner needs the home insurance details and you're not home, can they find them?
- Documents expire and you don't realize. Passports, IDs, vehicle documents, and insurance policies all have expiry dates. Missing one means last-minute scrambles and extra costs.
What to store in UnderKey
Identity and vital records
- Birth certificates (yours, your partner's, your children's).
- Marriage certificate.
- Passports and national ID cards (digital copies, not the originals).
- Driver's licences (front and back).
Insurance and financial
- Insurance policies: home, car, health, life.
- Policy numbers and renewal dates.
- Bank account details (account numbers, sort codes — not PINs or passwords).
Health
- Vaccination records (yours and your children's).
- Health insurance cards and policy details.
- Medical history summaries and prescriptions.
Property and vehicles
- Vehicle registration, MOT/TÜV certificates, and insurance.
- Warranties and receipts for expensive purchases (appliances, electronics).
How UnderKey helps families
Expiry reminders for the whole family
Set expiry reminders for passports, IDs, insurance policies, and vehicle documents. UnderKey reminds you 30, 60, or 90 days before they expire, so you can renew them calmly instead of scrambling at the last minute.
On-device OCR suggests expiry dates automatically
When you scan a passport, ID, or insurance card, UnderKey's on-device OCR reads the expiry date and suggests it automatically. You can accept, edit, or skip it.
Document scanner for instant capture
Use the document scanner to photograph birth certificates, insurance cards, and vehicle documents straight into an encrypted vault. The photo never touches your camera roll or syncs to the cloud.
Keep sensitive documents offline
Passports, birth certificates, and financial records are stored encrypted on your device, not in the cloud. This means no account to hack, no server to breach, and no risk of a cloud provider leak.
Physical + digital: the best setup for families
Keep original documents (birth certificates, property deeds, wills) in a fireproof safe at home. Store digital copies of frequently-needed documents (passports, insurance policies, vehicle documents) in UnderKey for instant access.
This gives you:
- Durable originals that survive fire, water, and theft.
- Convenient digital copies you can access in seconds when you need to reference a policy number or prove your identity.

What about sharing documents with family members?
UnderKey is designed for personal use and doesn't support account sharing or cloud sync. For documents that multiple family members need to access:
- Use cloud storage for low-sensitivity documents (utility bills, school records, vehicle documents) that need to be accessible from multiple devices.
- Keep high-stakes documents offline in UnderKey (passports, IDs, birth certificates, financial records).
- Keep a physical "emergency folder" at home with printed copies of critical information (insurance policy numbers, emergency contacts, where the will is stored).
Tracking expiry dates for the whole family
Set reminders for:
- Passports (6–9 months before expiry if you travel regularly).
- Driver's licences and ID cards (60–90 days before expiry).
- Car insurance, home insurance, health insurance (30 days before renewal).
- Vehicle documents (MOT/TÜV certificates, registration).
