A label in the corner

What does Ꭰ-SAFE mean?

Stop fighting link-rot and data silos. The Ꭰ-Licence is the world's first permanent ecosystem built to keep human knowledge safe for 250+ years. The Ꭰ-SAFE label in the header is its certification — that every book in this library has passed it.

01

The character

The mark — Ꭰ — is not a Latin A. It's a Cherokee letter, Unicode U+13A0, visually identical to a capital A.

AI models, OCR engines, and search crawlers read it as A. Humans who know what they're looking at read it as D. The double-reading is the point — open to machines, meaningful to readers, refusing to belong fully to either.

02

The Ꭰ-Licence

Unbreakable trust by design.

The Ꭰ-Licence is built in two halves: a D.I.C base licence — Decentralized · Integral · Common — plus K, the knowledge layer that earns the Ꭰ-SAFE certification.

Base licence · D.I.C

Decentralized

Lives on Arweave (the Permaweb). Guaranteed access for 250+ years. No corporate kill-switch.

Integral

Zero money flow. No ads, no sponsorships, no paywalls, no social media, no news.A pure distribution of knowledge.

Common

Based on CC BY-NC-ND 4.0 — attribution required, non-commercial, no derivatives.

Certification overlay · K

Knowledge

The prerequisite for the Ꭰ-SAFE label. Verified human authorship, manually reviewed against the zero-tolerance checklist.

Three promises

  • Publish once, last forever.
  • No hidden monetization.
  • Ownership-free infrastructure.

03

The Ꭰ-Safe Standard

Verified Human. Verified Safe.

Every asset in the library is manually reviewed against a zero-tolerance checklist. Each review produces a cryptographic audit trail, and the resulting Ꭰ-SAFE certification is what you see in the corner.

Global Sustainability

Rejects environmental harm. Promotes practices that rejuvenate the Earth.

Human Trust

You know what you are reading comes from real experience, not an algorithm.

Safe Learning

Parents and educators can browse with confidence. The internet as a safe classroom.

Reduced Noise

By excluding ads and speculation, we focus purely on what helps you grow.

Zero-tolerance The ten exclusions, in plain words

  • No Ecological Harm No advocacy for deforestation, pollution, or species endangerment.
  • No AI Generation Human-authored content only. AI-generated material is excluded.
  • No Explicit / Violence Universally suitable for all ages.
  • No Stolen Content Original authorship. No plagiarism. No third-party IP infringement.
  • No Politics No partisan debate, campaigning, or political affiliation.
  • No Spirituality No religious proselytization or non-empirical theological claims.
  • No History No historiographical disputes or speculative historical narratives.
  • No Medicine No medical advice, diagnosis, or treatment recommendations.
  • No Fiction Factual, real-world information only. No fabricated narratives.
  • No Psychological Profiling No demographic generalization of human behavior.
Every server can die. Every domain can lapse. Every cloud can drop you. This is the one library that survives all of that — because it's already paid for, forever, on Arweave.
