Protect Your Cookie Consent & Document Approvals with Cryptographic Proof
Collect consent. Preserve evidence. Prove what happened.
From cookie consent management to distance sales agreement approvals — built for KVKK, GDPR and global privacy requirements. Each record gets a SHA-256 digest and, where configured, an RFC 3161 timestamp, so later changes are detectable.
Why HashEntry?
Everything you need to protect your digital consents and document approvals.
Are your cookies a legal risk?
Cookies set without consent are a penalty risk. With HashEntry, the scripts you tag stay blocked until consent is given.
Can your document approvals be proven?
Sales contracts, privacy notices… Without a record of who approved which version and when, disputes are harder to resolve.
Can you prove consent records were never altered?
SHA-256 digests and RFC 3161 timestamps create a tamper-evident audit trail whose integrity anyone can verify independently. How much weight it carries is decided by the court or authority concerned.
Different countries, different rules?
Automatically apply region-specific consent policies based on visitor location.
