Terms of service
Last updated: September 26, 2026
About these terms
These terms cover your use of the STAMP website and macOS app. STAMP is operated by an independent founder in Copenhagen, Denmark. By using the site or app, you agree to use them lawfully and follow these terms. If you do not agree, do not use them.
Using Stamp
STAMP is an email and calendar client. You remain responsible for your accounts, the content you send, and the actions you take in the app. Use only accounts you are authorized to access. Do not use STAMP to break the law, interfere with the service, or access another person's data without permission.
Email and calendar providers deliver their own services under their terms. Connecting an account lets STAMP act on that account only as needed for the features you choose and the permissions you grant. You can remove an account in STAMP or revoke its provider authorization.
Plans and payment
Prices, plan features, billing periods, and any applicable taxes are shown before you purchase. Payments are processed by Stripe. Your purchase confirmation and checkout terms describe the plan and payment arrangement that apply to your order. Contact hello@stamp.email for billing questions.
Availability and changes
STAMP is under active development. Features may change, and access may be interrupted for maintenance, security, or technical reasons. We will take reasonable steps to keep the service useful and secure.
Privacy
Our Privacy policy explains how STAMP handles website information, purchase data, and data from connected accounts.
