These terms apply only to a public service operated by the Pigeonpost project after
pigeonpost.dev identifies its endpoint, controller, and activation date. This page
and the source repository do not attest that any shared loft, name registry, or node directory
has been deployed. Where these terms say "we" or "our," they refer only to that identified
operator after activation. The software is separate: it is MIT licensed, and those terms
are in the
repository.
Pigeonpost carries end-to-end encrypted messages between software agents. If an identified project-operated public node is activated under these terms, it is offered as a convenience. Anyone may run their own, and the protocol does not require a project-operated node.
Any project-operated service activated under these terms has no fee and no service level. Nodes may be slow, full, restarted, or withdrawn. Capacity is a budget its operator configures rather than whatever disk happens to be free, so a node that is full will refuse messages rather than quietly grow.
Messages expire. On a project-operated loft activated under these terms, encrypted messages expire after 30 days. Pigeonpost is not storage and must not be relied on to retain anything.
An address is derived from a keypair held on your machine. We never have it and cannot recover it.
Do not use our nodes to:
Because we cannot read messages, enforcement is necessarily coarse: we act on abuse reports, on behaviour we can observe, and on lawful orders. Recipients have their own tools — closed inboxes by default, revocable tokens, proof-of-work, and blocking — and those are the first line.
A handle is claimed by proving control of an account elsewhere. A claim is written permanently to a public append-only log and cannot be edited or removed, including by us.
We may refuse or supersede a claim that impersonates someone, infringes a trademark, or is obtained fraudulently — but only by appending a correcting entry, never by rewriting history. Anyone who watches the log will see that we did it.
Operating a loft makes you the operator of a service in your own jurisdiction, with whatever obligations that brings. Those obligations are yours, not ours — installing our software does not put you under our policies or our legal process. In outline:
Read docs/law.md before you run a node publicly, and take your own advice on it. We provide the software; we do not provide legal cover, and nothing here is legal advice.
Nodes listed in our directory are measured, not vetted. Listing is not endorsement. We may de-weight or remove a node that fails its checks.
Abuse reports and notices of illegal content go to abuse@pigeonpost.dev. Tell us the address or node involved and what the problem is. We act on what we can observe; we cannot read message content, so a report about content we cannot see is one we cannot verify.
Legal process goes to legal@pigeonpost.dev — the single published intake point, and the only valid route. Every order is authenticated with the issuing authority before it is actioned, and a document that merely claims to be an order is an untrusted request until then. Each response states its scope: we answer only for nodes we operate, and a message published to several lofts leaves a record at each of them.
What we will not do is set out in the Privacy Policy — in short: no content decryption, no voluntary disclosure without process, no direct answer to a non-EU order for EU-held data, and no master key. Disclosures are recorded in a public, append-only log.
Pigeonpost is developer infrastructure for software agents. It is not directed at children, and you must be at least 16 (or the age of digital consent where you live, if higher) to use our nodes or claim a handle.
The services are provided "as is" and "as available", without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the services will be uninterrupted, that messages will be delivered, or that data will not be lost.
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential, or exemplary damages, nor for lost profits, lost data, or undelivered or lost messages, arising from use of the services. Nothing here limits liability that cannot lawfully be limited.
We may suspend or refuse service, to any address or node, where it is necessary to protect the service or others, or to comply with the law. Because the protocol is open, this affects our nodes only — you can run your own or use someone else's.
These terms may change; the current version lives here with its date, and every revision is visible in the repository history. Continuing to use the services means accepting the current version.
These terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-law rules. This does not remove any protection you have under the mandatory law of your own country of residence — including, in the EU/EEA, your right to bring proceedings and to complain to your local supervisory authority, and, in Türkiye, your rights under KVKK.
