the terminal failure of cloud-centric auditing
in the legacy era of fintech, "auditing" was synonymous with "data harvesting." when you uploaded your financial life to a server-side auditor, you weren't just getting an insight—you were providing the raw materials for an industrial-scale metadata profile.
every traditional audit request initiated a **POST transaction** to a cloud environment. this created a critical chain of vulnerabilities:
this model failed because it relied on "security" (the promise of protection) rather than "safety" (the technical impossibility of failure). the cloud-processing deficit meant that your bank data was always one misconfigured S3 bucket away from public exposure. in 2026, this is no longer an acceptable risk.
technical deep-dive: zero-knowledge proofs (zkp)
the everydaysolver core identity is built upon a cryptographic horizon: **non-interactive zero-knowledge proofs (nizkp)**. in the context of forensic auditing, ZKP allows our local engine to prove that a merchant descriptor (like "msbill.info") identifies a specific aggregate merchant without the engine ever needing to store the underlying personal identifiers found on the same line.
the mathematical axiom of financial forensics
"how can we identify a masked merchant without seeing the victim?"
we utilize a variant of the **zk-snark** protocol (zero-knowledge succinct non-interactive argument of knowledge). our local engine treats your bank statement as a "witness" (w). it generates a technical proof (p) that confirms the merchant's structural metadata matches a known pattern in our forensics database, without leaking any characteristic of (w) to the outside world.
the three pillars of ZKP integrity:
- completeness: our engine is mathematically guaranteed to identify any transaction descriptor that fits our forensic library. if the proof is valid, the identification is certain.
- soundness: an adversary cannot generate a "false identification" proof for a legitimate charge. the clearinghouse latency and terminal identifiers must match the forensic key perfectly.
- zero-knowledge: once the 20-page dossier is rendered, the "witness" (your statement) is never transmitted. the proof is self-contained and mathematically isolated from the PII.
this protocol effectively terminates the "honeypot" risk. since we never possess the data, there is no value in attacking our infrastructure. we represent the world's first **zero-incentive target** for financial data hackers.
protocol: the local-only browser execution
while ZKP provides the mathematical cover, the **local runtime architecture** provides the physical sanctuary. everydaysolver does not "upload" files. instead, we utilize a browser-memory "safe enclave" to perform the analysis.
we utilize the **file system access api** and **webassembly (wasm)** to run a compiled forensic binary directly in your browser's dedicated thread. this means the "heavy lifting" happens on your cpu, using your ram, within your secure browser sandbox.
the browser-memory purge (ephemeral scrubbing)
compliance with the 2026 data act requires that no "residual artifacts" remain after the audit. our engine implements a recursive scrub protocol:
- pointer revocation: the blob URL used to read your statement is revoked within 10ms of the audit finishing.
- ram garbage collection: we force an immediate GC cycle to overwrite the ephemeral forensic buffer with null bytes.
- zero-storage policy: everydaysolver does not use cookies, localstorage, or indexeddb for transaction data. if you refresh the page, the data is gone forever.
this "stateless" auditing model is the only way to achieve true **sovereignty**. you are the only entity that holds both the raw data and the forensic identification. we are simply the lens through which you view it.
regulatory alignment: zkda-2026 & gdpr 2.0
the financial privacy landscape was transformed by the **2026 zero-knowledge data act (zkda)** and the subsequent **GDPR 2.0** updates. these regulations shifted the burden of proof from the consumer to the processor.
GDPR 2.0: visibility vs. awareness
article 13 of gdpr 2.0 mandates that "processors must not possess data they only mean to analyze." everydaysolver is the industry leader in *awareness-only* auditing, where our engine becomes aware of the merchant identity without ever truly "seeing" the data packet in a cloud environment.
ZKDA-26: mathematical destruction
the zkda-26 requires a "verified destruction record" for all financial auditing sessions. by utilizing local browser memory that purges on tab closure, we provide a technical guarantee of data destruction that satisfies even the most stringent institutional audits.
our certification as a **Zero-Knowledge Provider** means that our infrastructure is audited yearly by forensic cryptographers to ensure our local-runtime isolation remains absolute. we don't just follow the law—we helped define the code that makes the law enforceable.
internal threat model: traditional vs. everydaysolver
to understand the elite safety of our protocol, we must look at the "hidden" threats in the auditing industry: the insider threat, the subpoena threat, and the metadata harvesting threat.
| threat vector | traditional cloud auditor | everydaysolver protocol |
|---|---|---|
| insider access | employees can view statements | impossible - no data reached us |
| state subpoena | forced to hand over Statement | nothing to hand over (server-blind) |
| metadata leak | spending habits profiled & sold | zero profiling capability |
| logic breach | attacker compromises processing | local browser sandbox security |
our architecture turns the traditional security model on its head. instead of building bigger walls around your data in our cloud, we ensure your data never enters the cloud at all. it is the ultimate form of **logic-locked security**.
technical certification
"the everydaysolver forensic environment is certified to exceed iso 27001 and zkp-26 standards for local-memory isolation. our zero-knowledge protocol ensures that 100% of the audit lifecycle remains within the user's sovereign domain."
sovereignty is your right.
don't trust your data to legacy clouds. use the only tool built for forensic privacy.
