Consent and Digital Trust Platform: Purpose bound consent with tamper evident receipts

Kensara's consent and digital trust platform manages the full consent lifecycle, from discovery to proof. It scans your sites for every cookie and tracker, classifies them with AI and DPO review, and serves location-aware, accessible banners with equal Accept and Reject. Choices sync to Google, Microsoft and GPC signals, opt-outs reach Mailchimp, HubSpot and SendGrid, and every consent is saved as a tamper-evident, hash-chained receipt ready for audit.

Why we built this: We started Kensara doing DPDPA compliance advisory for Indian companies, and the same gap kept coming up. Every company had a cookie banner. Almost none could prove their consent records were genuine, and very few knew which trackers were firing on their own sites before a visitor clicked anything. DPDPA puts the burden of proof on the business, so a banner that only logs a click isn’t enough. The problem: Consent tools treat consent as a UI problem. We think it’s an evidence problem. Three things kept breaking: Trackers firing before consent, unnoticed Consent records sitting in ordinary database tables that anyone could edit Opt-outs that stopped at the website while the user stayed on the email list How our approach evolved: We built it around one rule- deterministic first, AI second, human last. A known-vendor database handles most trackers instantly, AI only handles the long tail, and anything uncertain goes to a DPO. The AI only ever sees tracker metadata, never personal data. On the trust side, every consent became a hash-chained, append-only receipt, so tampering is detectable. Withdrawals don’t count as done when an API returns 200; we check that the suppression actually happened. Today Kensara Consent & Digital Trust covers tracker discovery, jurisdiction-aware banners (EU, UK, India, US), Google Consent Mode v2 and GPC signals, tamper-evident consent records and verified withdrawal, built for DPDPA, GDPR and CCPA. We’re incubated at IIT Guwahati. We’d love your feedback.
