# Privacy Limits

Vayyl makes specific cryptographic facts private. It does not make the surrounding internet, wallet, or Stellar ledger disappear.

## Public boundaries

Shielding exposes the source, asset, amount, pool, and time. Public settlement exposes the asset, amount, destination, relayer, and time. A proof can hide which private note authorized the action; it cannot hide parameters that the Stellar asset transfer itself requires publicly.

## Correlation risks

Observers may correlate actions using:

* uncommon amounts;
* short deposit-to-withdrawal timing;
* a small or inactive privacy set;
* repeated destinations;
* relayer request metadata;
* wallet IP and browser fingerprints;
* unique application call patterns;
* compromised viewing or recovery keys.

## Mitigation direction

Private transfers and change keep intermediate activity away from public settlement. Relayers separate transaction submission. Batching can blur timing. Wallet guidance can discourage unique boundary patterns. Multiple applications sharing the note system add activity to the same set.

None of these produces a universal anonymity guarantee. Vayyl will describe measurable privacy properties and assumptions instead of promising that every use is untraceable.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://vayyl.gitbook.io/vayyl-docs/trust/privacy-limits.md?ask=<question>&goal=<endgoal>
```

`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.
