The small print.

What you can expect from Pigeon, and what we ask of you. Written to be read, not skimmed past.

Last updated 28 September 2026

Who we are

Pigeon is made by Henry Kirkness (“we”, “us”). These terms apply to the Pigeon app for macOS and the website at sentviapigeon.com. By downloading or using Pigeon you agree to them. If you have a question, write to henry@kirkness.com.

What Pigeon is

Pigeon is a mail app for the Mac. It connects to your Gmail, Google Workspace or Microsoft 365 mailbox, keeps a copy of your mail on your Mac so you can read and search it, and lets you reply, send and organise mail. It is not an email provider: your mailbox stays with Google or Microsoft, and their terms continue to apply to it. How Pigeon handles your data is set out in our privacy policy.

Free trial

Pigeon is free for 14 days, starting when your first mailbox has finished downloading. You don't need a card or an account for the trial. When it ends, Pigeon stops fetching new mail unless you have a licence. Everything already on your Mac stays there, and you can still read and search it.

Licences and payment

  • Pigeon is sold as a monthly or yearly subscription. Our payment provider, Polar, is the merchant of record: it takes payment, charges any sales tax or VAT, and sends your receipts. Its terms also apply to your purchase.
  • A subscription renews automatically at the end of each period until you cancel it. You can cancel at any time from the customer portal or by writing to us. It then runs to the end of the period you have paid for and does not renew.
  • If you subscribe during your trial, the days you have left are carried over and your first payment is taken when they run out.
  • A licence is for your own use, on up to three Macs at a time. You can move it to another Mac by deactivating it on one you no longer use. Please don't share or resell your licence key.
  • A founding-member price stays the same for as long as your subscription stays active. If it lapses or you cancel, the founding price ends with it.
  • If we change the price, we'll tell you at least 30 days before it affects a renewal, so you can cancel first if you want to.

Refunds

If Pigeon isn't for you, email henry@kirkness.com within 30 days of a payment and we'll refund it in full. No questions. This doesn't affect any rights you have under consumer law where you live.

Using Pigeon

You agree not to:

  • use Pigeon to send spam, or for anything unlawful, fraudulent or harmful;
  • connect a mailbox you are not allowed to access;
  • get around the licence check, or copy, resell or redistribute Pigeon, except where the law allows it;
  • reverse engineer Pigeon to attack it or the services it connects to. Security research reported to us in good faith is welcome.

You are responsible for the mail you send and the changes you make through Pigeon. Sending, deleting and labelling happen in your real mailbox, just as they would in any other mail app.

Claude and other services

Pigeon works with services we don't run, including Google, Microsoft, Polar and, if you install the plugin, Anthropic's Claude. Your use of those is governed by their own terms. We aren't responsible for them, or for what they do or stop doing. Claude can draft mail in Pigeon but never sends it: you always press send yourself, so check a draft before you do.

Updates

Pigeon updates itself. Updates may add, change or remove features. We'll try hard not to take away anything you rely on, and never anything you have paid for without telling you first.

Ownership

We own Pigeon, its name, its bird and its design. Your licence lets you use the app. It doesn't transfer any ownership. Your mail is yours: we claim no rights over it and never receive it.

No warranty

We work hard to make Pigeon reliable, but it is provided “as is”. We can't promise it will be free of bugs or always available, or that it will keep working if Google or Microsoft change their services. Pigeon keeps a copy of your mail, but it is not a backup service: your mailbox provider holds the original. Nothing here limits guarantees that consumer law gives you and that cannot be excluded.

Liability

To the extent the law allows, we are not liable for indirect or consequential losses, such as lost profits, lost business or lost data, and our total liability to you is limited to what you paid us in the 12 months before the claim. We don't exclude liability for death or personal injury caused by our negligence, for fraud, or for anything else the law does not allow us to exclude.

Ending these terms

You can stop using Pigeon at any time: cancel your subscription and delete the app and its data (see the privacy policy). We may suspend or end your licence if you seriously break these terms, and we'll tell you why. If we ever stop making Pigeon, we'll give you notice and refund the unused part of any subscription.

Changes to these terms

We may update these terms. If a change matters, we'll tell you in the app or by email before it applies, and the date at the top will change. If you keep using Pigeon after that, the new terms apply.

Law

These terms are governed by the law of England and Wales, and the courts of England and Wales can hear any dispute. If you live elsewhere in the UK or in the EU, you can also rely on the mandatory consumer protections of where you live, and bring a claim in your local courts.
