All three paid tiers open with a 21-day trial. You add a card when you start it, and nothing is charged until day 22 — cancel before then and the workspace drops back to the free tier with every note intact.

Any time, from Settings › Plan. We prorate the days you have already paid for and apply them as credit against the new rate, so an upgrade halfway through a month costs roughly half the difference.

Open Settings › Billing and choose Payment method. Cards, direct debit and invoice-by-email are all handled there, and a receipt lands in your inbox within a few minutes of every renewal.

Yes — verified students and teaching staff pay 42% less on the Personal tier for as long as the enrolment stays current. Verification runs once a year and takes about two minutes.

Teams runs a 14-day trial with a ceiling of 25 seats. Shared spaces, admin controls and the audit log are all switched on for the duration, so you can test the parts you actually need.

Convert in place: Settings › Plan › Move to Teams. Your notebooks stay exactly where they are and become your private space inside the new workspace, then you invite people by email or by domain.

We bill in 14 currencies, picked from your billing address at checkout. Switching currency means closing the current cycle first, so it is easiest to do at renewal rather than mid-month.

A student rate covers one person. For a reading group or a lab, the Teams tier is usually cheaper per head from about six people up, and every member keeps their own private notebooks alongside the shared ones.
