02 / The tradeoff today

You shouldn't have to choose between discipline and dignity.

People want to save consistently and contribute with trusted groups. The options available usually force a compromise on privacy or control. Three positions, one of which is ours.

A
Centralized SaaS

Habit, without privacy.

  • The platform sees every transaction.
  • Trust concentrated in one operator.
  • No verifiable privacy guarantee.
B
Public on-chain

Transparency, without restraint.

  • Every balance broadcast to the network.
  • Contribution history permanently public.
  • Surveillance becomes the default.
C
Circux

Transparent rules. Encrypted balances.

  • Balances stay encrypted on chain by default.
  • Rules and compliance are publicly verifiable.
  • You reveal private values only when you choose.
03 / The product

Two ways to save. One privacy model.

Circux keeps the product simple: save alone in a vault, or save together in a circle. The sensitive numbers stay private in both. Six capabilities, organized around that one decision.

01

Private vaults

Personal savings spaces for rent, tuition, emergencies, and any other goal. Encrypted balances. Clear progress.

02

Saving circles

Trusted contribution groups with cadence, payout mode, member status, and encrypted treasury values.

03

Rotating payouts

Ajo-style rounds show who has paid, who is pending, and who is next, without exposing private totals.

04

Milestone goals

Target-based circles and vaults keep sensitive amounts encrypted while showing whether the goal is on track.

05

Consistency signals

Readable streak and health bands help people coordinate without turning every balance into public gossip.

06

Permissioned reveal

Reveal controls sit beside the values they govern. Inspect your own numbers without making everyone else's public.

04 / How it works

One private balance. Two saving paths.

Fund your confidential balance once, then move into personal vaults or contribution circles with rules everyone can understand. Three chapters, one privacy model.

01
Solo saver

Save for a goal without telling anyone your balance.

Ada creates a vault for Rent 2027. Her balance stays encrypted, but her dashboard still shows progress, milestones, and whether the goal is on track.

02
Savings circle

Contribute with the people you trust. Not with their balances.

A group of five runs a monthly Ajo. Everyone sees the cadence, rules, round status, and payout readiness. Private contribution totals only reveal to the people allowed to see them.

03
Circle payout

Release money when the shared rule is satisfied.

For rotating circles, the next recipient unlocks after every active member pays the round. For milestone circles, payout readiness follows the target. The app shows the next safe action before money moves.

05 / The privacy model

Privacy is a design, not a feature.

Circux encrypts the sensitive parts of saving and leaves the coordination layer readable. You reveal your own values when you need them. Other people only see what their role allows.

01
Encrypted by default

Vault balances, circle treasuries, and member contribution totals stay encrypted when they are saved.

02
Reveal stays local

Reveal sits beside the value it controls. A person can inspect their own numbers without making everyone else's numbers public.

03
Roles, not exceptions

Members reveal their own contribution totals. Organizers see what they need to manage the circle. Nobody else sees private amounts.

06 / Security & trust

The privacy thesis doesn't negotiate.

Three commitments we don't walk back. They are the reason Circux exists rather than a faster fintech dashboard.

01

No admin override

We don't build backdoors into encrypted balances. If an admin could peek, the product would be a regular fintech dashboard in disguise.

02

Verifiable rules

Vault locks, milestone checks, rotating rounds, and payout readiness follow shared rules without exposing raw balances.

03

Permissioned reveal

Encrypted values are only useful when the right person can reveal the right value. Circux keeps that control next to the action.

07 / Open the app

Build wealth without broadcasting it.

A confidential savings layer. Save alone in a vault, save together in a circle, reveal what you choose. Nothing more.
