Entities

When you sign up for Clatri, the first thing you do -- without realizing it -- is create a personal entity. It's your default profile: your country, your currencies, your tax ID, your language. Everything you log from that point on -- expenses, medications, tasks, appointments -- is tied to that entity.

But an entity isn't just a profile. It's an isolated data space. Each entity has its own chat, its own calendar, its own bank accounts, its own history. If you run a coffee shop, the coffee shop's expenses shouldn't mix with your personal expenses. That's what business entities are for.

The rule is simple: a user can have one personal entity and multiple business entities. You switch between them from the entity selector in the chat app bar or from the dashboards, and each one works as an isolated data space.

Registration: first you, then your business

During onboarding, Clatri walks you through step by step:

1. Country and currencies -- defines where you operate and in which currencies. If you deal with crypto, you can register those too, though the system treats them as investments, not currencies
2. Tax ID -- your personal identification number (optional but recommended)
3. Health data -- biological sex and date of birth (optional)
4. Do you have a business? -- if you say yes, Clatri asks for your company details

That last step is where the system branches. And the key question is: does your business have a tax ID separate from yours?

Tax separation: independent entities vs sub-entities

This concept is simpler than it sounds. In most countries, a business can operate in two ways:

With its own legal identity -- the company has its own tax ID, different from yours. It's a separate legal entity: it has its own bank accounts, its own obligations, its own bookkeeping. In Clatri, this translates to an independent entity: fully separated from your personal entity, with its own data across all domains.

Without its own legal identity -- you operate as an individual with commercial activity. Your business uses your same tax ID. This is common for informal businesses, freelancers, or early-stage ventures. In Clatri, this translates to a sub-entity: a business entity that depends on your personal entity.

The practical difference matters:

	Independent entity	Sub-entity
Tax ID	Its own (different from personal)	Same as the personal entity
Country and currencies	Can be different	Inherited from the personal entity
Finances	Fully separated	Shared -- accounts, transactions, investments, obligations, and other financial data are visible from both entities

Why are finances shared in sub-entities? Because if your business operates under your same tax ID, your bank accounts are legally the same. Creating duplicate accounts makes no sense. Clatri reflects that reality: the sub-entity sees the personal entity's accounts and vice versa, and each transaction is recorded in the entity where you created it.

When you view your business entity as a sub-entity, you can display data in aggregate (personal + business together) or separate (business only). This is useful for seeing the full picture of your finances or isolating just the business transactions.

Sharing entities

Clatri lets you share an entity with other users. From the entity settings section, you can invite someone by entering their email address or user ID, and define what level of access they'll have.

Permission levels

• Owner -- full access, can manage the entity and invite other users
• Editor -- can view and edit data within the allowed domains
• Viewer -- read-only access

Access domains

In addition to the permission level, you define which domains the person can see:

• Everything -- full access to all domains
• Finances -- accounts, transactions, investments, debts
• Health -- conditions, medications, body metrics. You can share all health data or only period tracking, without exposing the rest of the medical information
• Management -- tasks, habits, calendar, bookmarks, notes, trips, timeline
• Chat -- conversation history

You can combine them: for example, share only Finances with your accountant, or Finances and Management with your business partner.

Invitations

When you share an entity, the other user receives an invitation they can accept or decline. Only if they accept does the entity appear in their entity list with the permissions you defined. This protects both sides: you control who has access, and the other person decides whether they want to receive that information.

Trip invitations

Beyond sharing a full entity, trips have their own invitation system. You can add travelers to a specific trip without sharing your entire entity -- each invited person sees only that trip and its itinerary. If a trip has visibility restricted to members, only invited travelers can access it.

Use cases

• Couples -- share the personal entity with Finances access to manage accounts together
• Companies -- share the business entity with employees, each with permissions tailored to their role
• External accountant -- viewer access to Finances so they can review without being able to modify
• Trips with friends -- invite travelers to a specific trip to plan together, without sharing the rest of your information
• Period tracking -- Clatri lets you share only period tracking with another person, without exposing the rest of your health data
