All information here is for explanation purposes only. {% endhint %} Our Honest Data Approach states the principle. This section shows the machinery. Silencio is engineered so that privacy does not depend on policy or good intentions: **it is enforced by how the system is built**, layer by layer, from the first tap in the app to the moment a dataset reaches a buyer. ### What is captured, by product For **Silencio Sound Check**, the network captures decibel-level measurements, dB(A), only. **Raw audio is never recorded, analyzed, or stored.** No conversation, no voice, no personal sound ever enters the system, which is also why aggregated noise data does not constitute personal data under GDPR Article 4(1). For **Silencio Voice AI**, audio is captured only when a contributor explicitly opts in, recording by recording. Every contribution is anonymized, stripped of personal identifiers, and quality-checked through **AI-driven scoring for clarity, completeness, and noise, followed by human review**, producing datasets that are privacy-compliant and enterprise-grade in the same pass. ### Anonymous from the start Contributors can participate under pseudonyms or non-identifiable emails. Identifiers are **hashed and stored separately from data streams**, so a contribution can never be walked back to a person. The network collects no names, no phone numbers, and no unnecessary personal data of any kind: **data minimization is the default, not a setting.** Consent that is granular, plain, and revocable. Consent is requested **dataset by dataset**, in plain language rather than legal jargon, and the app remains fully usable without any commercial data sharing at all. Contributors can view their contributions, revoke consent, or delete their data at any time. **No username or email is ever tied to raw data or visible to a buyer.** Every consent action is recorded on-chain, tied to a cryptographic machine ID and timestamp, creating the immutable audit trail described in **On-Chain Proof**, and giving every dataset the provenance the **EU AI Act** now demands of the companies that train on it. ### Privacy in commercialization Silencio sells **aggregated datasets and anonymized training corpora, never individual-level data.** A buyer may license anonymized multilingual voice datasets or noise averages across a city. A buyer can never see an identifiable contributor history, because the system holds no link between identity and data to expose. Every partner, from AI labs and enterprises to governments and academic institutions, operates under **strict data use agreements** that bind how datasets may be used downstream. ### Compliance, precisely stated Under **GDPR**, the network operates on Article 6(1)(b), contractual necessity, for core app function, and **Article 6(1)(a), explicit consent, for any commercial use of contributed data.** In the United States, the architecture is built for **CPRA, CPA, VCDPA, and the expanding family of state privacy frameworks.** Across all of it, six principles hold: **data minimization, the right to erasure, transparency, explicit consent for any microphone or location access, encrypted storage with strict access controls, and regular technical and legal audits** by external privacy and security specialists. ### A higher standard, on purpose Combining verifiable consent, minimal collection, machine validation, and human oversight, Silencio sets the benchmark for what ethical audio data means in practice. Contributors are protected, paid, and in control. Buyers receive data they can defend to any regulator. **Privacy is not an add-on here. It is the protocol.** --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://whitepaper.silencio.network/technical-overview/data-privacy-in-depth.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
