โฌก Features of the Temple โฌก

Nine Pillars of Privacy

Carved into stone. Immutable by design.

01

End-to-End Encryption

Every message sealed with XChaCha20-Poly1305. Only you and your recipient can read it.

02

Zero Metadata

No timestamps, no IP logs, no contact graphs. We cannot see who you talk to.

03

Open Source

All encryption code is auditable. Trust is verified, not assumed.

04

Disappearing Messages

Set any conversation to self-destruct. Burned to ash, unrecoverable.

05

Multi-Device

One identity, seamlessly synced across all your devices without key exposure.

06

Forward Secrecy

New session keys for every conversation. Past messages stay safe even if keys are compromised.

07

Self-Hostable

Run your own NABU server. Complete sovereignty over your infrastructure.

08

No Ads. Ever.

Your attention is not the product. Your data is not for sale. No exceptions.

09

No Tracking

No analytics SDKs, no fingerprinting, no behavioral profiling. Dark by design.
