Private by design — Stored forever — Paid for once

Private to you. Provable to anyone, forever.

Your files are locked on your device before upload, so no one — not even us — can read them. Stored forever, provable to anyone, and paid for just once.

No wallet required · Start with 2GB free · Pay only for what you store

Built for organizations requiring absolute data compliance, tamper-proof archives, and cryptographic access control.

Zero-Knowledge

Client-side encryption — we never see your files

On-Chain Verified

Every file has a provable Arweave transaction ID

Tamper-Proof

Stored permanently, so no one can alter or delete it

Pay Once

One up-front payment, with no subscription to keep it stored

Features

Built for Absolute Data Integrity

Production-ready infrastructure for compliance teams, data engineers, and decentralized networks.

Permanent Archival

One-time upfront payment stores your files indefinitely via decentralized networks. Eliminate recurring cloud storage subscriptions, renewal inflation, and data expiration. Your data remains fully accessible and independent of any single provider.

Cryptographic Access Control

Govern and decrypt files using secure cryptographic token credentials. Define precise, rule-based access layers so only authorized key holders can access protected content.

Zero-Knowledge Encryption

All files are encrypted client-side using military-grade AES-256-GCM before upload. We mathematically cannot see, access, or compromise your corporate content.

Verifiable Integrity & Audit Trails

Every file is anchored with an immutable on-chain transaction ID. Compliance auditors can independently verify that your data has never been tampered with or altered.

S3-Compatible API

Drop-in API for engineering teams. Seamlessly integrate permanent storage into your existing Web2 architecture by changing just your endpoint—no specialized protocol knowledge required.

Secure Data Repositories

Generate public or private administrative portals of permanently archived digital assets. Perfect for open-source repositories, legal baselines, and verifiable organizational history.

How It Works

Three steps to permanent storage

No crypto knowledge required. We handle the protocol complexity.

Step 01

Upload your file

Drag and drop or select your file. Optionally enable client-side encryption with a passphrase for zero-knowledge privacy.

Step 02

Pay once via Stripe

Pay the one-time permanent storage fee. We handle the underlying Arweave transaction — no crypto wallet needed.

Step 03

Stored forever, verifiable

Your file is permanently stored on Arweave. Get a shareable link with on-chain proof that anyone can independently verify.

Pricing

Pay once. Stored forever.

No subscriptions for storage itself. Subscriptions are for premium features like sync, token-gating, and team access.

FAQ

Frequently asked questions

Your file is stored on Arweave, a decentralized storage network with a permanent endowment model. Once uploaded and confirmed, the file exists on the network indefinitely — no renewal fees, no expiration, no company that can shut it down.

Every upload produces an on-chain transaction ID. You can independently verify your file's content hash against the Arweave blockchain at any time. This is cryptographic proof, not just a promise. Our verification page makes this easy.

No. We accept fiat payments via Stripe. You pay in USD (or your local currency), and we handle the underlying Arweave transaction on your behalf. The only time you might need a wallet is for token-gated access in Phase 2.

Our edge-cached CDN gateway at Cloudflare nodes worldwide significantly improves retrieval speed over raw Arweave gateway access. Files are cached and served from the nearest edge node for near-instant access.

Optionally, yes. You can enable client-side encryption before upload using AES-256-GCM. The encryption key never leaves your browser — we literally cannot see your file content. This is zero-knowledge encryption.

S3-compatible API access is coming in Phase 3. You'll be able to use your existing AWS SDK workflows with our permanent storage backend. Perfect for integrating permanent storage into your apps.

Nothing. Your files are stored on Arweave — a decentralized network that exists independently of any single company. Even if Aeterna disappears, your files remain accessible through any Arweave gateway.

By design, no. Permanent storage means permanent. This is the core value proposition — your files cannot be deleted, altered, or taken down by anyone, including us. Consider carefully what you store.

Your files deserve to exist forever.
