Body limits apply to systems you build or generate; catalogue systems open in full on every plan. "Device" means only your own computer sets the limit. Lifetime has Pioneer's limits.

Questions

Do I need to pay to use Teskooano?

No. The simulator, the catalogue and generated systems are free, and a free account lets you build and try systems in the editor and keep five saved systems, copied, imported or generated. Saving and downloading from the editor, and the exotic kinds of body such as black holes, giants and iron worlds, come with a paid plan. Paid plans add room to keep more and the tools to show it off.

Who takes the payment?

Paddle, my reseller. It takes the payment, handles VAT and sends your invoice. I never see your card.

Are prices in euros with VAT?

Yes. Every price is in euros and includes VAT, so what you see is what you pay.

Can I cancel?

Any time. Your plan runs to the end of the month or year you paid for, then drops to Free. Your saved systems stay; anything over the free limits becomes read-only until you upgrade again.

What does Lifetime mean?

Every Pioneer feature for as long as Teskooano exists, including features added later, and every app update, free. It includes 12 months of Pioneer-level API access and cloud storage. Those are the parts that cost money to run, so after that they're the optional Cloud add-on, at €1.99 a month or €21 a year. Without it, your saved systems stay, read-only over the free limits.

What are API units?

Each request an agent (through MCP), a script (through the API) or the command line makes uses units. Plans include a monthly allowance, and heavy months can add a top-up. After Lifetime's first year, API access is part of the Cloud add-on.
