How Your Data is Protected

Your data's security is our highest priority. Inheribase employs multiple layers of protection to ensure your digital legacy remains private and secure from upload to heir delivery.

1. Zero-Knowledge Architecture

Inheribase uses a zero-knowledge architecture, meaning we have no ability to access, read, or share your files. This is not a policy — it is a technical reality of how our system is designed.

Your files are encrypted with keys derived from credentials that only you know. Inheribase employees cannot view your files, passwords, or keys. Even under a valid legal order, we can only provide encrypted file blobs as we do not hold the decryption keys.

2. End-to-End Encryption

All data stored in Inheribase is protected with AES-256-GCM encryption, the standard used by governments and financial institutions.

1. Local Encryption: Your files are encrypted on your device before transmission.
2. Secure Transport: Only encrypted data travels over the network (via TLS 1.3).
3. Encrypted Storage: Our servers store only encrypted, unreadable blobs.
4. Local Decryption: Decryption occurs only on your authorized devices.

3. Cryptographic Data Integrity

When you entrust files to a digital inheritance platform, you need mathematical proof that the file your heir receives in 20 years is identical to the file you sealed today.

Inheribase provides this proof through SHA-256 verification:

• Your browser computes a SHA-256 hash of the original file before encryption.
• After submission, our servers independently verify the hash to ensure no transmission corruption.
• The verified hash is anchored on Base Mainnet, creating a tamper-proof record.
• When heirs download the file, their local client re-verifies the hash, proving absolute authenticity.

4. Data Permanence: The End of Rent

Traditional cloud storage operates on a "Rent" model. If you stop paying your monthly fee, your data is deleted. Inheribase ensures your estate is Owned, not Rented.

We utilize the Arweave network, a permanent decentralized data store. Once your data is stored, it is permanent by design.

• Instant Temporary Cache: Files are initially placed in a high-speed cache for instant confirmation.
• Arweave Settlement: The encrypted file is settled onto the Arweave blockweave. Once confirmed, it is permanent.
• Sustainable Endowment: A portion of your fee is sent to the Arweave Storage Endowment, covering the cost of maintaining your data for at least 200 years.

Even if Inheribase ceases to exist, your encrypted data can be retrieved from Arweave and decrypted by your guardians using open-source tools.
