No free plan. Here's why.
Your subscription pays for the app and what you use. We never sell or market your data. Running and improving Atrium costs real money, and we keep prices as low as we can.
Every limit, side by side
This table is built from the same plan data the app enforces. If you reach a limit, you can't add more of that one thing; nothing you already have is locked or deleted.

Questions
How does the free trial work?
A new account gets 14 days with every app. We don't ask for a card, and nothing is charged when the trial ends. You choose whether to subscribe — but if you haven't subscribed within 1 day after the trial ends, the account and everything in it is permanently deleted.
To keep public pages from being misused, a few things wait for a subscription: forms can't be shared outside your account, public polls, invitations and registries open once your email is confirmed and your account is a day old (two at a time), emails to guests are capped at 25 in total, and redirects after submitting are off.
What happens if I don't subscribe, or my plan ends?
The account is locked: you can subscribe or renew, export your data (up to twice) or delete it, and nothing else opens. A trial that ends without a subscription is permanently deleted 1 day later. A paid plan that lapses (an unpaid renewal after 24 hours, or a cancelled plan at the end of its year) is permanently deleted 30 days later, with every member of its team. The terms have the details.
How can I pay?
By card or with a PayPal account. Payments are processed by PayPal: card details go straight to PayPal and never reach our servers. Plans renew automatically at your price — once a year, or each month on monthly Business billing — charged to your default payment method. For yearly plans we email you 14 and 3 days before each renewal. Prices are in US dollars. If your billing address is in Canada, you're billed the same numbers in Canadian dollars: a plan listed at US$58.80 a year is charged CA$58.80, so you effectively save the exchange rate.
What if a payment fails?
We email you straight away, and you keep full access for 24 hours while you update your payment method. After that the account is suspended: you can renew, export your data (up to twice) or delete it. A suspended account is permanently deleted after 30 days; we email you again 24 hours before.
Can I pay monthly?
Personal and Family are billed once a year; the "about … a month" figure on those cards is only there to compare. Business can choose monthly or yearly billing when subscribing, and yearly costs about 30% less than paying monthly. You can switch between them from your billing page; the switch applies at your next renewal, so nothing is charged or refunded when you change it. Enterprise can be billed monthly or yearly too — talk to us.
How do Business seats work?
Business is priced per seat with a minimum of ten. The price includes ten seats, and you can add seats from your billing page as your team grows. A seat you add is charged right away for the rest of your current billing period (the month or the year); a seat you remove stays paid until your renewal, when the change takes effect. Need 25+ seats or custom terms? See Enterprise below the plans, or talk to us.
Can a Family plan have more people?
Yes. Family includes 4 people, and you can add more members for a fee each, up to the plan's limit, from your billing page. Family can also include accounts for children, which the owner sets up and can help recover.
Can I share with someone on a different account?
Sharing happens inside a Family, Business or Enterprise team: items, shared vaults, lists, contact books, budgets and calendars are shared with the people in your team. The Personal plan doesn't include sharing. Polls, invitations, registries and forms are different: anyone with the link can use them, no account needed.
Can someone who already has an account join my team?
No. An invitation creates a new account that belongs to your team, so only an email address without an Atrium account can be invited; someone who already has one can accept with a different address. Members can't leave on their own: the owner (or, on Business and Enterprise, an admin they allow) removes them, and what they stored in the team passes to the owner. A member can ask to have their account deleted, and it is removed within 30 days. Details: shared vaults, members and seats.
What is Enterprise?
Enterprise is for larger organisations: 25 seats and up, priced per seat, with custom terms built around your requirements. It isn't self-serve — contact us and we'll set it up with you.
What counts as a time-locked item?
Any vault item with a schedule attached. Personal allows 3 at a time, Family 10 for each person, and Business and Enterprise have no limit. Removing a schedule frees the slot.
Can you read my data?
Not in the vault, notes, calendar, lists, contacts or budgets: they are encrypted on your device with keys we never receive. We can see some metadata, such as sizes, timestamps and event times. Polls, invitations, registries and forms are built for people without an account, so our servers can read more of those. The security page lists it all, including the team owner's sealed copy of each member's key.
What if I forget my master password?
Use the Recovery Kit you saved at setup. We can't reset your master password because we never have it. If you lose both the password and the Recovery Kit, your data cannot be recovered, on any plan.
Can I cancel anytime?
Yes, from your billing page. Your plan keeps working until the end of the period you paid for, and nothing more is charged. To remove your only payment method, cancel first so there's no renewal to pay for.
