Nostr – canonical identity / DM
_@nip05.cowboybill.xyz This Nostr identity is my root cryptographic anchor. Any change of email, SimpleX link, or other channel (including Nostr) should be treated as authentic only if it’s confirmed via an event or DM from this identity.
SimpleX
https://smp18.simplex.im/a#XeCU6nKn89NMEo52ZzPIx-vffbmQ-Z3ZumM0LozMfv0 This SimpleX handle along with any invites may be rotated or revoked at any time. Keep in mind, SimpleX is the highest privacy form of contact, for now.
Email
contact@cowboybill.xyz To reduce noise and abuse: please include [CONTACT] in the subject for general contact. Messages without this tag may be deleted automatically without being read. Do not send sensitive information over email.
PGP
PGP key Fingerprint: E371 1F37 1EAC 7F94 f5E9 4C4E A18F F59A 4311 5258
Use this key to verify signed messages or, if needed, to encrypt email. Nostr and SimpleX remain the preferred secure channels.
Zap / Tip: ⚡
327c19b153c1a1b58f15bae8@coinos.io Optional sats channel for tips or proof-of-signal. Zaps do not guarantee a response, but may be treated as a higher-priority signal when combined with a contact message.

contact protocol

By using any channel above, you acknowledge the following:

1. No obligation
Contact does not create any obligation to respond, advise, or enter into a relationship, engagement, or contract of any kind. There is no guarantee of reply.
2. No implicit advice or contract
Messages and responses, if any, do not constitute financial, legal, medical, or professional advice, and do not establish a client or fiduciary relationship unless explicitly agreed elsewhere in writing.
3. Retention and deletion
Messages may be briefly stored, stored longer, or deleted at any time without notice. You should not assume archival, recoverability, or special confidentiality beyond the inherent limits of the channel you use. For more detail, see the Data Handling & Retention Policy.
4. Security model
Email is treated as an untrusted, non-confidential transport, primarily for initial contact and coordination. Nostr DMs and SimpleX are treated as higher-privacy channels, but no channel is absolute; use your own judgment for what you transmit. A more detailed breakdown of what this stack does and does not aim to defend against lives in the Threat Model & Scope.
5. Authenticity
The Nostr identity linked above is the canonical cryptographic anchor. Any change of email address, SimpleX link, or additional channel should be considered authentic only if it is confirmed via an event or DM from that Nostr identity. Treat any channel claiming to be "cowboy bill" without such confirmation as untrusted.

If you find a serious flaw in this contact protocol, the threat model, or the data policy, I'd sincerely appreciate it if you treat it as a bug report on the operating system and say so.
