Zero-Log in Practice: Kuaiya's Privacy Approach
"Zero-log" is often touted as a standard feature of accelerators, but truly delivering it is far harder than it sounds. On August 8, 2026, Kuaiya published a feature article disclosing how its zero-log policy is implemented in both governance and technology, addressing external scrutiny of this promise.
Zero-logging means recording no connection information traceable to a specific user — no browsing history, no destinations, no connection timestamps, no real IPs. It is not just a privacy pledge but an engineering practice requiring both technology and process, or it risks becoming mere marketing language.
Governance: Minimizing Data at the Source
Kuaiya follows a "data minimization" principle in its architecture. Functions that can use ephemeral sessions never persist to disk; statistics that can be anonymized are never tied to specific users. The team codifies this principle in internal norms and restricts data access through tiered permissions.
Kuaiya also established regular internal compliance audits, where personnel independent of business teams review data flows, ensuring the "no recording" promise is not broken during operation.
Technology: Leaving No Logs to Store
Technically, Kuaiya configures connection nodes to systematically disable log writes, or to use in-memory temporary buffers that are overwritten within a very short time. Even if a server were forensically seized, no meaningful connection history could be recovered.
The account system is decoupled from the connection system. Account data used for billing and login is not linked to connection data used for acceleration, preventing reverse-tracing of a user's network behavior through their account.
Data and External Verification
To strengthen credibility, Kuaiya invited a third-party security firm to independently assess its zero-log implementation. The report found no connection logs traceable to specific users during the sampled windows, consistent with the policy statement.
Some users said they chose Kuaiya precisely because it "willingly discloses log policy details rather than just slapping on a label." That transparency is key to whether a zero-log promise earns trust.
The Kuaiya team admits zero-logging is a long-term commitment, not a one-time declaration. It will keep introducing third-party audits and disclosing results, keeping the privacy promise within a verifiable framework.

Few products willingly disclose details like this — a big plus.
Transparency is exactly why I trust this service.
In-memory buffers plus overwrite is pragmatic, far better than empty talk.
Publishing the audit report would be even better — looking forward to it.
Account and connection data separation is a smart architecture choice.
