Terms of service

Last updated 12 November 2026

These terms cover your use of the Periph app for macOS and the periph.app website. By buying, downloading or using Periph you agree to them. If you don't agree, please don't use Periph.

Who sells Periph

Periph is made by an independent software developer ("we"). Orders are processed by Dodo Payments, which acts as the Merchant of Record: it handles payment, sales tax and VAT, invoices and receipts. Your purchase is also covered by Dodo Payments' buyer terms.

Your licence

• When you pay, you receive a personal, non-exclusive, non-transferable licence to use Periph.
• One licence activates Periph on one Mac at a time. You can move it to a different Mac by deactivating it on the old one first (Periph › Licence › Deactivate). If your Mac is lost or broken, email us and we will free the licence.
• The licence doesn't expire. Version 1 updates are free.
• You may not share, resell, publish or give away your licence key or the download link, or try to get around the licence check.

Price and payment

The price is shown on the pricing section in US dollars before you pay. It is a single payment, not a subscription. Taxes are calculated and shown at checkout by Dodo Payments.

Delivery

Periph is delivered digitally. Straight after payment you get a download link on screen and your licence key by email. Nothing is shipped.

Refunds

You can get a full refund within 14 days. See the refund and cancellation policy.

Acceptable use

Don't reverse-engineer, modify or redistribute Periph, except where the law allows it regardless of these terms. Don't use Periph to break the law or the terms of the services you connect to it.

Connected services

Periph can connect to your calendar, Claude Code, Codex, Stripe, Dodo Payments and Polar, at your choice. Those services are run by other companies under their own terms. You are responsible for the keys and accounts you connect.

No warranty

We work hard to make Periph reliable, but it is provided "as is". Periph is a visual aid: don't rely on it as the only way to catch meetings, payments or anything critical.

Limitation of liability

To the extent the law allows, our total liability for any claim about Periph is limited to the amount you paid for it. We are not liable for indirect or consequential losses, such as missed meetings or lost profits.

Ending your licence

If you seriously break these terms, for example by sharing your key publicly, we may disable your licence. Refunded and charged-back purchases are disabled automatically.

Changes

We may update these terms. The date at the top shows the latest version. Changes don't take away what you already bought.
