StampNameSupport
Need help? Write to support@stampname.app. Include your Mac's macOS version and, for license questions, the email you bought with. Please do not send invoices or other documents.
Are my documents uploaded anywhere?
No. StampName reads and names your files on your Mac. StampName contacts the license server only to activate and check your license key, and never sends document content. See the Privacy Policy.
Where is my license key?
Polar emails it to the address you used at checkout, and we also send it from license@stampname.app, usually within a minute. Check spam. Then open StampName, go to Settings, choose License, paste the key and choose Activate. If it has not arrived, write to us with your order email.
I lost my license key.
Go to stampname.app/account, enter the email you bought with and the 6-digit code we send you. You will see your key with a Copy button, the Macs it is activated on, and a Deactivate this Mac button for each.
How many Macs can I use my key on?
Up to 3. To move a key, open Settings, choose License and use Deactivate this Mac on the old Mac, then activate on the new one. If you no longer have the old Mac, deactivate it from your account page.
Pro turned off, or the app says my license is not valid.
The app checks your key at launch and about once a day. If you are offline it keeps working for up to 14 days after the last successful check. A refunded order, a revoked key or an ended yearly subscription locks the app. Reconnect and reopen the app, or contact us.
Can I undo a rename?
Yes. StampName keeps a local journal of your renames. Undo is always free.
How do I get a refund?
Write to us within 14 days of purchase with your order email and we will refund through Polar.
How do I cancel the yearly subscription?
Cancel in the Polar customer portal (it is also linked from your account page), or write to us. The yearly plan renews unless you cancel.
System requirements
A Mac running macOS 26 or later.
