Terms & Conditions

Interaction Protocol

One deliberate entry opens one bounded composition.

This is the boundary for Composium.app.

Composium is not ambient. It does not begin because you arrived, opened a page, received a Card, or signed into an account. The instrument becomes operative when you choose to enter it.

What follows is the protocol for that interaction.

1. Boundary

Composium.app is a compositional instrument operated by Composium Oy.

You enter with material you want to bring into composition. Composium provides the bounded structure in which that material can be listened to, composed, resolved, and conducted.

Entering one composition does not authorize another.

Access to one composition does not create access to another.

Nothing moves merely because it is technically possible for it to move.

By choosing Compose, you deliberately enter one composition and request that Composium begin performing it immediately.

2. Instrument

One composition contains a 300-second active composition interval.

During that interval, you provide the material. Composium conducts the instrument.

The instrument may use artificial intelligence as part of the compositional process. AI processing is bounded to the composition you entered and does not create authority over you, your identity, your other compositions, or your life outside that composition.

Composium is not a substitute for your judgment.

The instrument conducts a composition with you. It does not conduct you.

3. Composition

The material you bring remains yours to the extent you hold rights in it.

Inside the bounded composition, your material is processed toward a definite form. Raw input, runtime state, resolution, custody, and outward movement are different things and are not treated as interchangeable.

Composium does not make your unresolved material public merely because you entered it.

Composium does not treat payment, authentication, proximity, inference, or technical access as permission for unrelated uses.

The detailed handling of personal and compositional data is governed by Privacy.

The conditions under which the instrument may operate on and hold a composition are governed by Conditions.

4. Click

A composition reaches resolution when the instrument commits a definite compositional state.

That resolution is the Click.

The Click does not mean that Composium has decided for you. It means that the bounded composition has reached the point from which conduct can begin.

Resolution occurs before release.

Payment does not manufacture the composition and does not make it yours.

Your composition is already yours.

If you choose to release the resolved Card, the price is €4.

There is no subscription, automatic renewal, or recurring charge attached to one composition.

5. Card

The Composium Card is the portable form of the resolved composition.

It carries the resolved composition out of the runtime so that it can be encountered, kept, shared, situated, or conducted elsewhere.

The Card may leave.

The runtime does not.

Releasing a Card does not transfer ownership of your composition to Composium. Receiving or sharing a Card does not, by itself, transfer ownership to anyone else.

The Card may be accessible through a shareable address after release. Anyone to whom you give that address may be able to view the released Card. That does not give them access to your account, Vault, runtime, or other compositions.

6. Conduct

After resolution, movement happens only through deliberate crossings.

Save asks Composium to hold a composition in authenticated custody.

Reference creates an explicit authorized relation between compositions. It does not silently merge them or reopen an earlier runtime.

Send moves a Card outward through a pathway you choose.

Offer to Composium creates only the particular further relationship you deliberately request. It does not create an automatic session, project, or continuing authority.

Remove from Vault ends visible custody there. It is not the same act as deleting the composition.

Delete composition requests erasure of the composition to the extent Composium can lawfully erase it.

Exit closes the active composition.

A permission created by one crossing does not silently become permission for another.

How resolved compositions move through and out of Composium is governed in detail by Conduct.

Composium keeps and processes only the data required by the operation, deliberate custody, security, transactions, or applicable law, as described in Privacy.

7. Port

Exit ends the active authority of that composition.

Anything you deliberately saved, released, referenced, sent, or otherwise conducted remains subject to the crossing you chose. Exit does not reach backward and undo an outward movement already completed.

Returning to Composium.app after Exit does not reopen the composition.

Home is ground.

Another composition requires another deliberate entry.

The boundary is therefore simple:

Terms governs the relationship and transaction.

Privacy governs personal and compositional data.

© 2026 Composium marks the ownership center: your composition is yours; Composium's instrument is Composium's.

Conditions governs how composition may exist and be held inside the instrument.

Conduct governs how resolved composition may move.

These Terms & Conditions operate together with those documents. Where mandatory law gives you rights that differ from this protocol, mandatory law prevails.

For consumer transactions, Composium provides the information and obtains any express request or acknowledgement required by applicable withdrawal law at the crossing where it is relevant. Entering Compose and choosing to pay €4 to release a Card are separate actions.
