To cancel your GraphPad Prism subscription, sign in at graphpad.com/myaccount with the email tied to your license, click “Manage Plan,” and then click “Cancel.” Future renewals stop, but you keep full access through the end of your current billing term.1GraphPad. How Do I Purchase, Order, or Cancel Prism Before you click, read the sections below on refunds and data export. Both catch people out.
Cancel Through the My Account Portal
Your username is the email address tied to the subscription. If you’re not sure which one that is, open Prism and choose “About Prism” from the Help menu on Windows or the Prism menu on Mac. That screen shows your serial number, which support can use to look you up.2GraphPad. How Can I Find My Serial Number
Once you’re signed in at graphpad.com/myaccount, open “Manage Plan” and click “Cancel.” The portal confirms that your subscription will not renew.1GraphPad. How Do I Purchase, Order, or Cancel Prism GraphPad doesn’t publish a minimum notice period before a renewal charge, so don’t wait until the last day of your cycle. A week or two of cushion protects you from processing delays.
Personal subscribers can confirm the change by scrolling to the invoice list at the bottom of “Manage Plan.” Group subscribers find invoices under the “Billing” tab.3GraphPad. How Do I Get a Copy of My Invoice
If the Portal Won’t Let You Cancel
Submit a request at help.graphpad.com with your serial number, registered email, and a clear statement that you want to cancel. GraphPad says it typically replies to support emails within an hour or two.4GraphPad. GraphPad Prism 11 User Guide – Technical Support There is no phone support, so email is the only assisted route. A representative will verify your identity and disable future billing.
Group and Institutional Licenses
If your license came through a university, employer, or reseller, you cannot cancel it yourself. The administrator who bought the group plan controls billing and seat assignments through the My Account portal.5GraphPad. How Do I Manage My Group License Contact that person, usually someone in departmental IT or procurement, and ask them to remove your seat or cancel the plan.
Administrators can reassign a seat rather than cancel it when someone leaves, but GraphPad enforces fair-use limits on how often seats can be reassigned. If the administrator hits that cap, further changes have to wait.6GraphPad. Prism License Limits If you don’t know who your administrator is, GraphPad support can identify them from your serial number.
Export Your Data First
This is the step people skip and later regret. When your subscription ends, Prism drops into Viewer Mode. You can open files and print them, but you cannot copy data, export graphs, or edit anything.7GraphPad. Where Can I Find the Prism Viewer Results that live only in the .pzfx format become effectively trapped.
While you still have full access, export what you’ll need later. Use the Export button on the toolbar or go to File → Export. Graphs save as PNG, TIFF, EPS, or PDF, and can go straight to PowerPoint or Word. Raw data copies out of the data tables into a spreadsheet or a CSV.8GraphPad.

What You Can Still Do in Viewer Mode
Viewer Mode is free and doesn’t expire, so your .pzfx files won’t disappear. You can open them, move through data tables, graphs, and results sheets, inspect the analysis parameters behind any test, and print any sheet. You cannot enter or edit data, change analysis settings, modify graphs, copy text, or export.7GraphPad. Where Can I Find the Prism Viewer Read-only, in a meaningful sense.
Refunds and Timing
GraphPad’s Product Terms of Service state that all fees are non-cancelable and non-refundable.9GraphPad. GraphPad Product Terms of Service No 30-day window, no prorating for unused months, no exception in the published terms.
Because refunds aren’t on offer, cancel as soon as you know you’re done. If your annual plan renews in August and you decide in March, cancel in March. You keep full access through August and eliminate the risk of an accidental renewal. Monthly subscribers have less on the line each cycle but should still cancel before the next billing date. A calendar reminder a few days ahead of the renewal date is worth setting if subscriptions tend to slip past you.
