Plans

One proof, or many every day.

  1. Layer 1

    The proof

    Your file fingerprint, recorded on public chains. It is the foundation and it is not charged for.

    What you pay
    Nothing
    How long it lasts
    Forever
    What it depends on
    Nobody: it checks out with the package you already hold

  2. Layer 2

    The qualified seal

    A timestamping authority of the FNMT-RCM fixes the date. The file that proves it travels inside your package.

    What you pay
    €6, once (from €1.50 in packs)
    How long it lasts
    Forever, once issued
    What it depends on
    Nobody: FNMT has signed it and you hold it

  3. Layer 3

    Custody

    We keep the original file as well, and check it is still the same one every time you download it.

    What you pay
    €5 a month
    How long it lasts
    As long as the subscription
    What it depends on
    On Sellat’s custody service. Your proof package stays valid without it

Qualified seal packs

If you are going to seal several things, buying them together costs less.

A move-in inventory is many photos, and a renovation is many stages. Every seal in a pack is the same qualified timestamp issued by the FNMT-RCM, with the same legal presumption of date across the EU. Packs only bring the price down, without subscribing to anything.

Before you buy a pack

Bought seals do not expire and are used before any single payment. You need an account, because a balance has to belong to someone. Since nothing is issued when you buy them, you keep the 14-day right of withdrawal over the ones you have not spent.

You can buy as many packs as you like and they accumulate: the seals add up in one balance, and the oldest pack is spent first.

Packs and custody are separate purchases: neither adds to nor discounts the other.

Custody

For keeping the original

€5 a month, VAT included

We keep the original file behind your proof and check it is still the same one every time you download it.

Custody

  • Your original, kept in the European Union
  • 5 GB of storage
  • Up to 50 MB per file
  • Integrity checked against the fingerprint on every download
  • Up to 50 downloads a day
  • Cancel whenever you like from your account
  • Paid yearly, 5 qualified seals included every year (€30 of value). Whatever you do not use stays in your account.

  • Everything in the free account
How you want to pay

The year is paid up front and renews on its own. You can cancel whenever you like from your account: custody stays active until the period you have already paid for ends.

The proof stays valid even if you do not store the original file. Custody adds preservation; it does not replace or condition the proof.

One per person, on the proof you choose. After that, €6 per timestamp.

Public verification does not consume protections.
