Frequently asked questions

In brief

Key answers about cashboxes, accounts, usage and prices.

What is the team or shared cashbox?

It manages shared income and expenses, members, roles, contributions, penalties, donations and exports. The cashbox manager buys; invited members remain free.

What is the event cashbox?

It combines deposits, budget and expenses for an event. The event manager keeps track of participants and settlement. The first event is free once: up to five weeks and ten people including the event manager.

How do private expenses work?

Participants can pay privately and record the payer and payment method immediately. The expense is settled with the event cashbox later, so nobody owes another person money.

Why do I need a personal account?

The account with email and password assigns cashboxes, roles and invitations to the right person. Email verification protects that assignment and restores access on another device.

How do I sign in or change devices?

After verifying the email, sign in with the same email and password. Cashboxes, events, roles and invitations linked to that account appear on the other device.

Can I use SiMaDoo in a browser?

Yes. The web app runs at simadoo.com/app/ without installation. Purchases are disabled in the browser and happen only after explicit confirmation in the Apple or Google app.

How does the free trial work?

The three free months start when the first team cashbox is created. Downloading and testing do not trigger a purchase. If you buy early, payment is immediate and the twelve paid months start after the trial.

How much does SiMaDoo cost?

Event cashbox full version: €4.99 permanently. Team Basic: €18.99, Team Premium: €26.99 and Premium package: €28.99, each for twelve months. All are one-time purchases without automatic renewal.
