Privacy Without Trust

Give your users true sovereignty over their data, today. TACo is the first and only access control layer you aren’t forced to trust.
Start BuildingTrust Overview

End-to-End Encryption. End-to-End Decentralized.

Empower users to share data with qualifying recipients, and no-one else. Encryption via a decentralized cryptosystem, from day one.

Web3 needs TACo

Decentralized Storage

TACo is the perfect complement to persistent storage, finally enabling users to grant future access without having to download & re-encrypt locally.

Web3 Social Networks

TACo facilitates many-to-many data sharing, without a centralized authority that may harvest, exploit and monetize interpersonal communication.

Media Content-gating

Whether it's a stream, a movie or a collectible, TACo enforces the decryption rights. 'Owning' an NFT now holds significance beyond a symbolic receipt.

The Web needs TACo

Hyper-sensitive data

From password recovery to reproductive healthcare, TACo ensures that high-stakes data sharing doesn’t necessitate trusting an intermediary.

IoT & Connected Vehicles

TACo is the antidote to the interconnected hardware panopticon, in which every waking (and sleeping) moment of life is surveilled/harvested by data custodians.

Activism & Human Rights

TACo protects the most vulnerable in society – those who may face intimidation, censorship and violence as a consequence of their data being leaked.

Integrate a Privacy Layer with Nothing to Hide

TACo isn't just auditable, it's comprehensible. From high-level schematic to client code.
