ZeroTrace automatically logs every message, consent, and deletion event — across WhatsApp and Telegram — in a cryptographic chain anchored daily to Polygon. When GDPR inspection arrives, you have evidence. Not excuses.
Every day, millions of clinics, lawyers, and HR firms send sensitive messages via WhatsApp with zero audit trail. One complaint to a data protection authority — and you have no proof.
Connect once. ZeroTrace runs silently in the background — every event is logged, signed, and anchored automatically.
If you discuss health, money, legal matters, or personal data over WhatsApp or Telegram — GDPR applies to you. ZeroTrace is your protection.
Each add-on works standalone or combines into the Shield bundle. Buy individually or save 40% with the full package.
OneTrust costs $25,000/year and requires a dedicated privacy team. ZeroTrace is plug-and-play, from $49/month.

ZeroTrace generates a tamper-proof technical record of your data processing activities. It is not legal advice and does not certify compliance — that's your DPO's job. What it gives you is the documentation your lawyer needs if a regulator ever asks questions. Think of it as the evidence locker, not the verdict.
ZeroTrace has two independent integrity layers, and they answer different questions:
Layer 1 — local HMAC audit chain (self-attested integrity). Every event is written into an append-only chain, each entry signed with an HMAC-SHA256 signature derived from a key we hold, and linked to the previous entry's hash. This proves that we did not modify the chain after each entry was written. It is what a regulator asks for when checking Art. 30 records — a tamper-evident internal register. Limitation: because the signing key is ours, the guarantee is that we haven't tampered; a third party still needs to trust that we didn't manipulate an entry before we signed it.
Layer 2 — daily Polygon anchor (third-party verifiable timestamp). ZeroTrace is designed to compute a daily Merkle root over the platform-level audit chains and write it to the Polygon blockchain as a zero-value transaction. The transaction hash on Polygonscan.com then provides an independent, non-repudiable proof that the state of the chain existed at that exact timestamp — a fact anyone can check without trusting us. This is the layer that lets a regulator or opposing counsel verify our records without relying on our word.
Current status of Layer 2: operational since 2026-08-27 (UTC) — genesis anchor tx e261814e0cf7d0fd… in block 92779361, verifiable on Polygonscan without trusting us. Each new audit entry becomes Layer-2-covered on the next daily anchor run at 02:00 UTC — from write to on-chain proof, lag is up to 24 hours. Entries predating 2026-08-27 remain under Layer 1 only — by design, Layer 2 does not backfill retroactively.
Yes. ZeroTrace is a standalone product. You can use it purely for audit trail and compliance documentation without any AI chatbot. If you later want to add WhatsApp AI automation, BossBot integrates natively.
On the Professional plan, the DSAR Robot handles this automatically. When a customer types "delete my data" in any supported language (EN/PT/ES/RU/FR), ZeroTrace deletes all their records, generates a signed Proof-of-Deletion receipt, emails you a confirmation with the full audit log, and closes the request. The 30-day GDPR deadline is never at risk.
No. We never store raw phone numbers or names in the audit chain. Phone numbers are one-way hashed using per-client HMAC keys — mathematically impossible to reverse. What goes to the blockchain is a hash of hashes — it contains zero personal information.
Each Polygon transaction costs approximately $0.0001. For daily anchoring over a year, that's about $0.04 total. We cover this cost — it's included in all Professional and Business plans.
