Proton licensing is the set of terms under which Proton AG sells its privacy-focused services. The Terms of Service describe the Services as Proton Mail, Proton Calendar, Proton Drive, Proton VPN, Proton Pass, Proton Meet and Proton Docs, with Proton Wallet operated by a subsidiary under separate terms, and they state that the Services are operated by Proton AG, a Swiss company in Geneva.[1] Proton does not publish a separate end-user licence agreement for the web services. The Terms of Service are the single contract for individuals and organizations, and the plan chosen decides which features and limits apply.[1]
Three audiences are served. Individuals choose among a free account, single-service Plus plans and the Proton Unlimited bundle. Families choose Proton Duo (two users) or Proton Family (up to six users). Organizations choose Proton for Business plans, which are priced per user.[2][4]

Metrics
Proton does not name a licence metric. The units that decide what a plan allows are the following, and each has a catalog row.
- Users. Business plans are priced per user, and the Help Center says an organization can hold up to 5,000 users before the customer is asked to contact enterprise sales.[6]
- Storage. All paid plans have encrypted storage shared between Proton Mail and Proton Drive.[2] Free has 1 GB for Mail and up to 5 GB for Drive, Mail Plus 15 GB, Unlimited 500 GB, Duo 2 TB and Family 3 TB shared among members.[2]
- Email addresses and custom domains. Each plan lists the number of addresses and domains; for example Mail Plus allows 10 addresses and 1 custom domain and Unlimited allows 15 addresses and 3 domains.[3]
- Family group members. Duo allows two users and Family or Visionary allow six.[5]
- Simultaneous VPN connections and dedicated VPN servers. Paid VPN plans allow 10 devices at a time per user.[2]
Counting and floors
Floors apply mainly to business plans. VPN Essentials and VPN Professional carry a minimum of 2 users, and Pass Essentials, Pass Professional and VPN and Pass Professional a minimum of 3 users.[4] To turn a business plan into an organization the customer needs at least one additional user and a connected custom domain, and once created an organization cannot be deleted.[6] A Primary Admin is the administrator who is responsible for the organization’s billing, and changes to users and add-ons are prorated only when made from that account.[7][5]
For personal plans the count is the plan itself: a Plus plan or Unlimited has one user, Duo two and Family six. A family group has a primary administrator who manages billing and memberships for the group.[9]
Virtualization and partitioning
Proton documents no virtualization or device-based licensing. The partitioning concepts are account-level. A paid plan is linked to the account it was bought for and cannot be transferred to another account.[1] Terms of Service Section 2 also lists, as unauthorized, sharing an account or login credentials, trading or selling an account (Lifetime Accounts excepted, which can be traded only through Proton), reselling or sublicensing the Services, and keeping multiple free accounts, except where the subscription plan expressly permits it or Proton agrees in writing.[1]
Cloud and entitlement mechanics
All Proton plans are cloud services. Subscriptions renew automatically for the purchased billing period, and a renewal is charged at the then-current price.[1] A subscription can be cancelled within 30 days of the initial purchase for a full refund, once per user, if it was bought directly from Proton.[1] A new paid plan takes effect immediately with a prorated credit, while cancellation keeps the plan until the end of the period.[1][8] If a payment fails the account can be downgraded to Free and, if it exceeds Free limits, placed in a delinquent restricted state; Proton may delete such an account after 12 months.[1] These rules are covered in Proton Terms of Service, billing and refunds.
Programs
- Business free trial. The business plans page advertises a 14-day free trial and a 30-day money-back guarantee; the Terms say a business trial becomes a paid subscription unless cancelled.[4][1]
- Proton Unlimited trial. A user who leaves a Duo or Family group gets a 30-day Proton Unlimited trial.[9]
- Student discount. Students in the US, UK, France and Germany can apply through Student Beans for discounts on 12-month plans.[10]
- Nonprofits and journalists. Special pricing is stated to be available, with no published percentage.[4]
- Add-ons. Extra users, custom domains, Scribe, Lumo Plus, Meet Professional and dedicated VPN servers can be added to eligible plans.[5]
Out of scope
This article does not cover Proton’s encryption design, privacy policy, Lumo AI terms, Proton Wallet terms or open-source licences of the apps. It also does not cover reseller or app-store purchases, where the refund and renewal rules of the store apply instead of Proton’s. The wiki’s coverage of comparable services is in Dashlane licensing, 1Password licensing and Bitwarden licensing.
