This Privacy Policy explains how personal data may be processed when you use Klima Protocol websites and any related verification-gated features. Most Klima Protocol activity is on-chain and therefore public by design.
Controller: Klima Fintech Ltd.

This policy covers:
This policy does not replace third-party policies for vendors you interact with directly (e.g., zkMe). Where relevant, we link to those resources.
When you interact with Klima Protocol smart contracts, the blockchain will record information such as:
This information:
Some features may require verification to align with market integrity, counterparty requirements, or risk controls that the ecosystem chooses to apply (for example, to reduce fraud/abuse or meet expectations of certain carbon market participants).
Klima Fintech Ltd.: controller for the limited verification result data we maintain (see below).
zkMe: processes identity verification inputs (documents, liveness checks, screening) within their systems.

zkMe may perform (depending on configuration):
What we receive from zkMe:
We do not store any of this information in our own systems; it is held within the zkMe platform.
What we do not have access to:
To enable verification-gated access and (where applicable) minting/association of a non-transferable proof, zkMe must be able to associate a verification result to a wallet address. Depending on implementation, this may occur because:
In all cases, the wallet address is the only identifier we expect to share for this purpose, and we do not send identity documents to zkMe.
After successful verification, a non-transferable on-chain proof/attestation may be minted or referenced for gating.
This proof/attestation:
Choose a wallet you are comfortable associating with this proof/attestation.
We may revoke gating or require re-verification if risk changes (e.g., policy updates, suspected fraud, sanctions list updates, or integrity concerns).

We do not use analytics for advertising profiling.
Where required by law, we provide a cookie consent mechanism.
Where GDPR/UK GDPR applies, we process limited personal data for:
We do not sell personal data.
We may share limited data as follows:
zkMe processes identity verification inputs within zkMe systems. We receive and store only the limited outcomes/references described above. zkMe may use sub-processors; refer to zkMe’s published materials for details.
We may use service providers for security monitoring, auditing, incident response, or infrastructure. Where used, access is limited and subject to contractual and technical safeguards. Data involved is expected to be limited to items like wallet addresses, timestamps, and security logs.
Only where required by law or upon lawful request, we may disclose information we hold. In practice, this is expected to be limited to wallet addresses and gating/verification status metadata (not identity documents, which we do not hold).
On-chain records are retained according to blockchain characteristics and are not controlled by us.
Verification data (including email address and citizenship status) is held within the zkMe platform and is not stored in Klima's own systems. Refer to zkMe's terms and policies for their retention practices.
We may maintain a wallet-address-to-gating-status mapping for the purpose of operating verification-gated access controls, audit, and abuse prevention.
zkMe’s retention and deletion practices are controlled by zkMe. Refer to zkMe’s terms/policies for how long they retain verification inputs and what deletion options exist.
Subject to applicable law, you may request:
Notes (important limitations)
To exercise rights: privacy@klimaprotocol.com and include the wallet address(es) relevant to your request.
You may also have the right to complain to your local supervisory authority where applicable.
Blockchain infrastructure is global by design.
For off-chain processing, vendors (including zkMe) and infrastructure providers may process data in multiple jurisdictions. Where required, appropriate safeguards are used (e.g., SCCs/IDTA/adequacy decisions). You can request more detail via privacy@klimaprotocol.com.
We apply reasonable technical and organizational measures appropriate to the limited off-chain data we process. Measures may include controls such as encryption in transit, access controls, logging/monitoring, and vendor management. Blockchain security is governed by the underlying networks and your wallet provider.
Klima Protocol services described here are intended for individuals 18+. We do not knowingly verify minors.
We may update this policy from time to time. The “Last updated” date will change, and material updates will be posted on this page.
