Audit

Consent receipts & evidence

Prove consent for any visitor and date.

In short
Every consent is stored with a policy version, a policy hash and a receipt ID, and records are bound into a per-record SHA-256 hash chain you can verify with a single command. When an auditor asks you to prove valid consent for a specific visitor on a specific date, you can.

Stored rows are not the same as provable evidence. When an auditor asks you to prove a specific visitor consented on a specific date, most teams cannot. ConsentX issues a receipt for every consent and binds records into a SHA-256 hash chain you can verify with one command.

Each consent gets a hashed receipt; records are chained so any tampering is detectable.

The problem

When an auditor asks you to prove a specific visitor consented on a specific date, most teams cannot. Stored rows are not the same as provable, tamper-evident evidence.

With ConsentX

Every consent carries a receipt and a hash, chained so tampering is detectable. You resolve a per-visitor receipt and export audit evidence in minutes, not weeks.

How it works

01

Snapshot the notice

ConsentX versions and hashes the policy text the visitor actually saw.

02

Issue a receipt

Each consent gets a Kantara-style receipt with the policy version and hash.

03

Verify the chain

A SHA-256 hash chain binds records so tampering is detectable on demand.

A closer look

A receipt for every decision

ConsentX versions and hashes the exact notice the visitor saw, then issues a Kantara-style consent receipt carrying the policy version, the policy hash, the categories chosen and a receipt ID. The receipt captures what was agreed to, not just that something was.

You can resolve a per-visitor receipt on demand, showing precisely what a given person agreed to and when, which is what vendor-risk reviews and regulators actually ask for.

Tamper-evident by design

Records are bound into a per-record SHA-256 hash chain, so altering any historical consent breaks the chain and is detectable. A reports:verify command checks integrity, turning your consent log into evidence rather than a list of rows that could have been edited.

Audit evidence exports in minutes, with monthly compliance reports (PDF and CSV) and a per-record hash chain that makes the export defensible.

Frequently asked questions

What does tamper-evident mean?+

Records are chained with SHA-256 so any change breaks the chain and is detectable. It is provable, not just stored.

Can I prove consent for one visitor?+

Yes. You can resolve a per-visitor receipt showing exactly what they agreed to and when.

What is a consent receipt?+

A Kantara-style record of what the visitor was shown and agreed to, including the policy version and hash.
