Security and privacy

Your information belongs to you. Not to us.

The short answers come first: what Unidy does with your information, who can see it, and what happens if something goes wrong. The technical details follow, for anyone who wants them.

One key for every person. No master key. The keys are kept apart from the information, so stealing the database isn't enough to read your data.

Can I trust Unidy with my information?

What you should know before trusting us with your information.

  • Do you sell my personal data?

    No. We never sell your information or use it to build advertising profiles.

  • What happens when I connect with someone?

    Nothing of yours is shared automatically. You decide what each person can see, and you can change it whenever you want.

  • Can Unidy’s staff see my information?

    Only if you ask them for help, for example to correct a detail you can’t change yourself. Then they open only what that help needs, and every access is recorded in your Audit.

  • What if someone steals the database?

    Your data is encrypted with individual keys, kept in a separate system. A copy of the database isn't enough to read it.

  • What happens when I share a document?

    Unidy makes a protected copy for the recipient. You decide what they can see and for how long.

  • What if I lose my phone?

    Your documents stay protected in Unidy. Sign in from another device and they are all there.

Every access is recorded.

Our team never opens your information on its own. Only if you ask for help, for example to change a detail you can’t change yourself, can they reach what that help needs.

Our staff have no direct access to the servers. The databases and your documents stay encrypted there, and the only way in is Unidy’s own support tool, which opens nothing without your request.

Every access needs a reason, and it’s recorded in your Audit.

What this does not protect you from

Every system has limits. These are ours, in plain words.

  • Someone who breaks into Unidy’s servers

    A database or files stolen from Unidy are scrambled on their own. To read even one person’s information, an attacker also needs that person’s key from the separate key vault, and the root key that locks the vault, which is in neither database. That’s far harder than the breaches that leak millions of readable records. Not impossible.

  • A shared copy someone already downloaded

    Ending access stops anyone opening the copy through Unidy. Unidy can't take back a copy someone downloaded, printed or photographed.

  • Details you choose to share with someone

    Unidy lets you share one detail instead of a whole passport. Still, once someone has seen a detail, Unidy can't make them forget it.

  • Someone who can sign in to your Unidy account as you

    Whoever signs in as you sees what you see. That's why your Unidy offers a second step at sign-in.

The technical details

How the protection works underneath

The same protections, with the exact methods, for anyone who wants to check them.

What anyone would see inside Unidy’s database

Unidy’s database holds a record for every person with a Unidy account, like you. Every one of those records is encrypted with that person’s own key. So whoever looks inside the database, Unidy’s staff included, sees scrambled characters in place of your personal details and documents.

Scrambled. Each record needs its own person’s key.

  • One key for each person

    Your name, your home address, your phone numbers and your documents are locked with your own key. Your neighbor’s are locked with theirs. Reading everyone would take every person’s key, one by one.

  • The keys are somewhere else

    The keys live in a separate key vault, with its own program and its own database. A copy of Unidy’s database holds no key at all.

  • Your documents are encrypted too

    Every document is stored as a file of scrambled bytes. Even a photo of your pet. Each file has its own key, and that key is locked with yours.

A data breach at an ordinary company leaks millions of readable records. A copy of Unidy’s database leaks scrambled characters.

How your information is protected

Five simple rules for everything you add to your Unidy.

  1. 1

    Every document encrypted, each with its own key

    Everything you keep is encrypted with AES-256. Every document has a key of its own.

  2. 2

    One key per person

    Each document's key is sealed with your own personal key. There's no master key, so a stolen database isn't everyone's information at once.

  3. 3

    Keys kept apart from your information

    The keys live in a separate key vault, with its own program and its own database. The vault is sealed with a root key kept outside both databases: it opens the personal keys, never your information directly. Without those keys, your information is just scrambled text.

  4. 4

    When your key is used

    Your key is used to show you your information while you're signed in, and to read a new document and draw its thumbnail.

  5. 5

    Every use of a key, recorded

    Each time a key is used, the vault writes down when and what for.

Why your keys are kept in Unidy’s vault, not on your phone

Keeping the only key on your phone sounds safer. Until the phone is lost, stolen or replaced.

If the only key to your documents lived on your phone

  • Lose the phone, and your documents are gone for good
  • Nobody can help you get your documents back
  • A new phone starts without your documents

What Unidy does instead

  • Keys kept apart from your information, one per person
  • Sign in on a new phone, and all your documents are there
  • Protection against the break-ins companies suffer, like a stolen database

The honest trade: a service that can show you your documents can read them. So we say it plainly, and every use of a key is recorded.

What you can check yourself

You don't have to take our word for these.
