Features

Bank-grade rigor.
App-level simplicity.

The standards that protect major banks, double-entry bookkeeping and sealed ledgers, made accessible to everyone.

The books always balance

Every expense automatically creates two opposite entries. No calculation errors, no floating figures. The balance sheet is always accurate, to the cent.

DEBIT = CREDIT · ALWAYS

A ledger that can't be tampered with

Every entry carries a unique mathematical signature, linked to the previous one. Any attempt to alter the past is detected instantly.

TAMPER-PROOF LEDGER

You decide who sees what

Create separate spaces for personal, couple, family, or micro-business use. Each person has a clear role: viewer, contributor, administrator or owner.

4 ACCESS LEVELS

Full history, to the second

A chronological view of every movement. Balance before, balance after. A visual indicator confirms on every line that your data integrity is intact.

CSV EXPORT FOR YOUR ACCOUNTANT

Organize your way

Ready-to-use categories, or build your own structure. Each subcategory can have its own color and icon for instant dashboard readability.

2-LEVEL HIERARCHY

Your numbers. Exact.

See your monthly cash flow, expense breakdown, and net worth evolution. Concrete data based on your real numbers, not fuzzy estimates.

REAL DATA · MATH PRECISION
Security & integrity

A ledger that cannot be falsified.

Every entry carries a unique digital signature. An architecture of trust, without the complexity.

Sealed ledger

Every entry points mathematically to the previous one. Any modification of the past is impossible to conceal.

Simultaneous entries

The debit and credit are recorded at the same time. The general ledger can never be unbalanced.

Isolation and traceability

Each group is a sealed silo. Every action, whether viewing or editing, is logged in a complete audit journal.

Background audit

A module continuously verifies the consistency of your books and validates every cent, without you having to think about it.

Comparison

Side by side.
The difference is clear.

Nothing escapes

Everything is captured. Nothing escapes.

Every transaction is SHA-256 hashed and chained to the previous one. Altering a single line would break the entire chain. Your audit trail is as immutable as the hadal trench.

These hashes are computed live in your browser. Try tampering with an entry: Chain intact — every hash matches.

FAQ

Straight
answers.

No marketing jargon. The reality of our infrastructure, in plain English.

What is double-entry bookkeeping?
It's the standard used by businesses and financial institutions: every transaction creates two opposite entries (debit / credit) that balance each other. Hadalos does this automatically. You enter a transaction, the system handles the rest. Result: zero calculation errors, ever.
Is my data sold to third parties?
Never. Our business model is entirely subscription-based, not advertising. Unlike free tools, we have no commercial interest in analyzing your spending habits. Your privacy is built into our code, not buried in a long contract.
What happens if I leave the platform?
You remain in control of your data. You can export your full history as CSV at any time. If you delete your account, your data is erased from our servers within 30 days, in accordance with our purge protocols.
How does Pre-Alpha access work?
We are in an intensive testing phase to stabilize the infrastructure. Access is limited. Sign up for the waitlist: we open spots as we validate the robustness of the ledger and backups.
Can I invite my accountant or spouse?
Yes. Through role-based access control, you can invite someone as read-only (your accountant can review the ledger and reports, without modifying anything) or with full edit access (your spouse, your partner). You stay in control.
Data compliance and sovereignty?
Absolutely. Hadalos is built and hosted in Canada, under Canadian personal information protection laws, including data portability and transparency of processing.
