Frequently asked questions

How does the Pro trial work?

Every new account starts with 7 days of the Pro plan — no card, no charge. When the days are up the account moves to the free plan; nothing is charged and nothing you created is lost, and you can subscribe whenever you want.

Does the free plan have a time limit?

No. You can use secondbrain for free as long as you want, within the storage and feature limits of the free plan.

How is it billed?

Paid plans are billed monthly and in advance, in US dollars, and renew automatically until you cancel. Details are in the Terms of Service.

Can I change plans?

Yes. Upgrades apply immediately and prorate the current period; downgrades take effect from the next cycle.

Can I get a refund?

Yes, within 14 days of your first paid subscription. Full conditions are in the Refund Policy.

What happens to my content if I cancel?

Your content stays available: the account returns to the free plan when the billed period ends, within that plan's limits.

Which integrations are included?

Calendars (Google, Microsoft/Outlook, Apple), ClickUp and MCP support. Each one is optional and only connects when you authorize it — see Privacy.
