Sovereignty doesn't end with you.
Lethean is the digital testamentary executor. We automate the right to erasure (GDPR Art. 17) post-mortem, at scale, across 500+ platforms.
“When you go, your data goes with you.”
Three movements. One certainty.
Mandate
While alive, you sign a fiduciary mandate via eIDAS qualified signature. Encrypted, witnessed, legally binding.
Trigger
A verified death certificate — cross-checked with the Belgian National Register — triggers the protocol. No false positives.
Execute
Automated erasure across 500+ platforms. SaaS, social, banking, data brokers. Audit log delivered to the estate.
Built on law, not promises.
GDPR Article 17
Right to erasure. Personal data must be erased without undue delay upon valid request — enforced across the EU by the Belgian DPA (APD/GBA).
Belgian Data Protection Act — 30 July 2018
Implements GDPR in Belgian law and recognises post-mortem rights over personal data via Article 9 directives.
eIDAS Regulation (EU) 910/2014
Qualified electronic signatures carry the same legal value as handwritten signatures — making the Lethean mandate enforceable across the EU.

Five things lawyers ask first.
Yes. The mandate is signed via eIDAS qualified electronic signature (e.g. itsme® or eID), giving it the same legal value as a handwritten signature under Regulation (EU) 910/2014 — recognised in all 27 Member States.
We escalate via formal Article 17 notice. Non-compliance is reported to the Belgian Data Protection Authority (APD/GBA). Refusal carries fines up to 4% of global turnover.
Cross-validation with the Belgian National Register and equivalent civil registries across the EU. A 14-day quiet period prevents fraudulent triggers.
Personal data rights are extra-patrimonial — they do not transfer to the estate. The deceased's wishes prevail under the Belgian Data Protection Act and GDPR.
Cryptographic shredding. Keys are destroyed across all replicas. The audit log is the only artifact preserved — for the estate, for seven years.
