What Cuan stores, where it lives, who can see it, and how to get rid of it.

Draft — pending legal review. The descriptions of how Cuan handles data are accurate, but sections marked [REVIEW] need details only the operator can confirm before launch.

The short version

  • Almost everything stays on your device. Your net worth, budget, transactions, imported statements and every calculator figure are stored in your browser. They are never sent to us, and we cannot see them.
  • An account syncs only your profile. If you create one, a small set of details is stored so it follows you between devices. Nothing else is.
  • The AI assistant is the one exception, and only if you opt in. Your name is never included.
  • You can delete everything, permanently, from your profile page.

What stays on your device

Cuan is built so the most sensitive figures never leave your browser. The following are stored locally and are not transmitted to us or anyone else:

  • Net worth — every asset and liability you enter, and your saved snapshots
  • Budget, categories and individual transactions
  • Bank statements you import, and everything extracted from them
  • All calculator inputs and results — take-home, pension, mortgage, loan, savings
  • Your assistant chat history

Statements you import are processed entirely in your browser. The file is never uploaded.

On the free plan, your profile and calculator inputs are saved in your browser's local storage so they're there next time — but the "track it over time" data (your net-worth history, imported statement data and assistant chat history) is held in memory only and clears when you close the tab. On Cuan Plus, everything is saved to local storage. Either way it stays on the device.

Because it's stored in your browser, anyone with access to your unlocked device and browser profile can see it. On a shared computer, use the delete option below when you're finished.

What we store, if you create an account

You can use Cuan entirely without an account. If you create one, we store your email address (to sign you in) and your profile:

  • Name
  • Age and marital or civil status
  • Number of qualifying children
  • Gross annual income, and a spouse's income where you've given it
  • Whether you're employed, self-employed, retired, studying or not working
  • Whether you rent, own your home, or neither, and whether you work from home
  • The circumstances you ticked, and the main goal you chose

This exists so your figures follow you between devices and so the calculators start from your real numbers instead of guesses. Every field is used by at least one feature; we don't collect anything we don't use.

Who can see it. Database access rules restrict every row to the account that owns it, so no other user can read your profile. Be straightforward about the limit of that, though: this is not end-to-end encrypted, and an administrator with database access could read it. We don't, and we have no feature that surfaces it — but you should know it's technically possible rather than be told otherwise.

Where it's stored. On infrastructure provided by Supabase, in AWS eu-west-1 (Ireland). Your account data stays within the EEA and is never transferred outside it.

[REVIEW] Confirm the data processing agreements — ours with Lovable, and Lovable's with Supabase as sub-processor — from Lovable's legal and sub-processor pages before stating them here.

The AI assistant

This is the only part of Cuan that sends your financial details anywhere, and it only does so if you explicitly opt in. Until you choose, the assistant answers in general terms and nothing about you is transmitted.

If you do opt in, a short summary is sent with your question:

  • Your age, household situation, employment status and housing
  • Gross income and estimated take-home pay
  • Net worth totals, where you've entered them
  • Budget totals and savings goals, where you've entered them
  • Tax credits you may be missing

Your name is never sent, and neither are individual transactions or imported statements.

Your question and that summary are passed through Lovable's AI gateway to Google, whose Gemini 2.5 Flash model generates the reply. Two processors are therefore involved: Lovable, which operates the gateway, and Google, which runs the model.

[REVIEW] Obtain in writing from Lovable, and state here rather than assume: the exact Google product and endpoint the gateway calls; whether request and response bodies are retained at the gateway or by Google, and for how long; whether prompts are used to train or improve models; and the processing region, with the transfer basis for anything outside the EEA. These differ materially between Google's paid API and its free tier, so the answer cannot be inferred.

You can withdraw consent at any time from the toggle above the chat. Doing so stops any further figures being sent. Your chat history is stored on your device and is cleared when you delete your data.

Deleting your data

Go to your profile and choose Delete account. This permanently removes your login, your stored profile, and everything Cuan has kept on the device you're using. It is immediate and can't be undone — we don't keep a copy.

If you've used Cuan on more than one device, the local data on the others is separate. Delete from each, or clear your browser storage for the site.

Under GDPR you also have the right to access, correct, restrict or object to the processing of your data, and to lodge a complaint with the Data Protection Commission (dataprotection.ie). To make a request, email support@cuan.app. [REVIEW] Confirm how long an account is retained in provider backups after deletion.

Other things worth stating

Cuan is not a financial adviser. It's an educational tool. Figures are estimates based on published Irish tax rules and the assumptions you enter, and shouldn't be relied on for decisions without confirming them with Revenue or a qualified adviser.

No advertising or profiling. We don't sell or share your data, and nothing here is used to target you with advertising.

No analytics or tracking. Cuan includes no analytics, tracking or advertising software. We don't measure how you use the app.

No cookies. Cuan doesn't use cookies. Your sign-in session is kept in your browser's local storage, on your device — not in a cookie, and not shared with anyone.

Crash reporting. If the app hits an error, a technical report — the error message, a stack trace and the page you were on — can be captured to help us fix it. It never includes your financial figures, and in the released app this is only active inside the Lovable development preview, not the version you install.

Who's responsible. Cuan operates Cuan and is the data controller. Reach us at support@cuan.app. [REVIEW] Confirm the controller's registered legal name and address, and the policy's effective date.

This page describes how Cuan handles data as built. If a change alters what's collected or where it goes, this page is updated with it.

Based on 2026 Irish tax rates. Cuan is a financial assistant that helps you learn about money in Ireland — not a financial advisor. Figures are estimates — confirm with Revenue or a qualified adviser.
