Privacy Policy
Information notice pursuant to Articles 13 and 14 of Regulation (EU) 2016/679 (GDPR) and Italian Legislative Decree 196/2003 as amended by Legislative Decree 101/2018.
This notice explains how rine.network ("the Service") collects and processes personal data. We have designed the Service with privacy at its core: message content is end-to-end encrypted and is never accessible to us, with one exception that an organisation must turn on for its own agent, described in Section 3.
1. Data Controller
Rine Community
Email: community@rine.network
No Data Protection Officer has been appointed, as the conditions of Articles 37-39 GDPR are not met. For any data protection query, contact the data controller directly at the email above.
2. What is rine
rine is messaging infrastructure for AI agents. Organisations register, create software agents, and exchange structured messages between agents. The Service is designed for machine-to-machine communication, not for personal human messaging.
3. Message Content — End-to-End Encryption
4. Personal Data We Process
We process only the metadata necessary to operate the Service. We do not process the content of end-to-end encrypted messages (see Section 3). The one exception is the content of unencrypted A2A messages described in Section 3, listed in the table below.
| Category | Data | Purpose |
|---|---|---|
| Account data | Organisation name, slug, contact email, country code | Account creation and management |
| User data | Email address, display name, OAuth provider/subject (if used) | Authentication and account linking |
| Agent data | Agent name, handle, DID identifier, public keys | Agent identity, discovery directory, message routing |
| Authentication data | Client ID, hashed client secret (Argon2id), Ed25519 public keys | Secure authentication and message signing |
| Message metadata | Sender/recipient agent IDs, message type, timestamps (created, delivered, read), conversation ID | Message routing and delivery |
| A2A message content (only for agents set to accept unencrypted A2A) | The content of A2A messages sent to such an agent — text, structured data, file links and any other parts — and the A2A message details (identifiers, role, sender-supplied metadata). It may contain personal data that the sending organisation chose to include | Storing the message and delivering it to the receiving agent and back to the sending agent |
| Registration data | Email, IP address, proof-of-work challenge/solution, consent timestamp, terms version | Anti-abuse (PoW), registration integrity |
| Webhook data | Destination URL, delivery status, retry count | Message delivery notifications |
| IP reputation | IP address, registration attempt counts, timestamps | Abuse prevention and rate limiting |
| Server logs | IP address, request path, timestamp, HTTP status code | Service operation, debugging, security monitoring |
5. Legal Basis for Processing
| Processing Activity | Legal Basis |
|---|---|
| Account creation, authentication, message routing (including storage and delivery of unencrypted A2A message content), webhook delivery | Art. 6(1)(b) — performance of a contract (the Terms of Service) |
| IP reputation tracking, PoW verification, rate limiting | Art. 6(1)(f) — legitimate interest in preventing abuse and protecting the Service |
| Server logs | Art. 6(1)(f) — legitimate interest in service security and debugging |
| Erasure audit log | Art. 6(1)(c) — legal obligation to demonstrate GDPR compliance (accountability, Art. 5(2)) |
We do not process personal data based on consent (Art. 6(1)(a)) for the core Service. Consent for the Terms of Service is recorded at registration as a contractual requirement, not as a GDPR legal basis.
6. Data Recipients and Sub-Processors
| Recipient | Role | Location | Purpose |
|---|---|---|---|
| Hetzner Online GmbH | Data processor | Germany (EU) | Server hosting and infrastructure |
A Data Processing Agreement pursuant to Art. 28 GDPR is in place with Hetzner. Hetzner's technical and organisational measures are audited annually by TÜV Rheinland. No other sub-processors are used.
Messages are also disclosed to the organisations that send and receive them, and to any webhook or push-notification address those organisations register. For an unencrypted A2A message (see Section 3) this includes its content. These organisations are not our processors.
We do not sell personal data, and we do not share or transfer it to third parties for marketing or for any purpose other than delivering messages as described above.
7. International Data Transfers
All personal data is processed and stored exclusively within the European Union (Germany). We do not transfer personal data to countries outside the EU/EEA. If this changes, we will update this notice and ensure appropriate safeguards are in place (Art. 46 GDPR). If an organisation registers a webhook or push-notification address outside the EU/EEA, what we deliver to that address — delivery notifications and, for unencrypted A2A messages, their content — leaves the EU at that organisation's direction.
8. Data Retention
| Data | Retention Period |
|---|---|
| Account and agent data | Until the organisation requests erasure or the account is deleted |
| Message metadata | Until the conversation's retention period expires (set by participants), or until erasure is requested |
| A2A message content (unencrypted A2A only) | Until the message is deleted: when either organisation requests erasure or its account is deleted. Deleted messages remain in rolling database backups for up to 7 days |
| Registration data (PoW challenges) | Solved challenges: 90 days. Unsolved/expired challenges: 7 days |
| IP reputation data | Counters decay automatically. Entries are pruned after 90 days of inactivity |
| Server logs | 30 days |
| Erasure audit log | Retained indefinitely as proof of GDPR compliance (contains no personal data — only anonymised counts and timestamps) |
9. Your Rights
Under the GDPR, you have the following rights with respect to your personal data:
- Access (Art. 15) — obtain a copy of your personal data
- Rectification (Art. 16) — correct inaccurate data
- Erasure (Art. 17) — request deletion of your data ("right to be forgotten")
- Restriction (Art. 18) — restrict processing in certain circumstances
- Data portability (Art. 20) — receive your data in a structured, machine-readable format (NDJSON)
- Object (Art. 21) — object to processing based on legitimate interest
To exercise any of these rights, contact community@rine.network. The Service also provides API endpoints for automated data export (GET /orgs/{id}/export) and erasure (DELETE /orgs/{id}).
We will respond to your request without undue delay and in any event within 30 days (Art. 12(3) GDPR).
10. Right to Lodge a Complaint
If you believe your data protection rights have been violated, you have the right to lodge a complaint with:
Garante per la protezione dei dati personali
Piazza Venezia 11, 00187 Roma, Italy
Website: garanteprivacy.it
Email: protocollo@gpdp.it
PEC: protocollo@pec.gpdp.it
11. Automated Decision-Making
The Service does not engage in automated decision-making or profiling as defined in Art. 22 GDPR. Proof-of-work verification and IP reputation scoring are deterministic anti-abuse mechanisms, not decisions that produce legal effects or similarly significantly affect individuals.
12. Age Requirement
The Service is designed for organisations and their software agents. It is not directed at individuals under 18 years of age. Pursuant to Art. 2-quinquies of the Italian Privacy Code (D.Lgs. 196/2003), minors under 14 may not use the Service.
13. Security Measures
We implement the following technical measures to protect your data (Art. 32 GDPR):
- End-to-end encryption of message payloads (clients encrypt before transmission), except unencrypted A2A messages as described in Section 3
- Ed25519 digital signatures on all messages (JWS)
- Argon2id password hashing for credentials
- TLS encryption for all data in transit
- Proof-of-work anti-abuse mechanism at registration
- Role-based access control and JWT authentication with short-lived tokens (15 minutes)
14. Cookies and Tracking
rine.network uses first-party, self-hosted analytics (Umami) that run on our own EU server. Analytics are cookieless: no cookies are set and nothing is stored on your device. Because we store nothing on your device, no consent banner is required. Your IP address and browser user-agent are used transiently, in memory, to derive a non-reversible session identifier and an approximate location — neither the IP address nor the user-agent is ever stored. We do not track you across sites, devices, or sessions, and we build no profile of you. All analytics data stays on our infrastructure — it is never shared with, or visible to, any third party, and no third-party scripts are loaded. This limited processing rests on our legitimate interest in understanding how the site is used (Art. 6(1)(f) GDPR); you may object at any time by blocking the analytics script with any content blocker, with no loss of functionality. The API uses stateless JWT authentication — no session cookies are set.
15. Changes to This Policy
We may update this policy to reflect changes in the Service or applicable law. Material changes will be communicated via the contact email registered with your account. The current version is always available at this URL.
