Privacy Policy

Last updated 13 July 2026

Quidough is a paid, hosted personal-finance app for households. Because you pay for it, you're the customer – not the product. This policy explains, in plain language, what we hold, why, and the promises we keep. If you've read how Quidough works, none of this will surprise you.

The short version

  • We never sell, share, or monetise your data. No ad networks, no analytics that ship your finances elsewhere, no "anonymised" resale.
  • No bank middleman. Quidough doesn't connect to your bank through an outside service, so no third company gets a copy of your data. You add or import it yourself.
  • Your data is always yours. Export all of it, or delete your account, whenever you want.
  • We're honest about security. Your data is encrypted and access is tightly controlled – and we tell you plainly what that does and doesn't mean.

1. Who we are

Quidough is a product of Cambridge Motion Ltd, a company registered in England and Wales (company no. 08115942, registered office 483 Green Lanes, London N13 4BS, United Kingdom). We trade as "Quidough" and refer to ourselves here as "Quidough", "we", or "us". For the purposes of UK data-protection law, Cambridge Motion Ltd is the controller of the personal data described below.

If you have any question about this policy or your data, contact us at hello@quidough.com.

2. What we collect

We keep as little as the service needs to work, and no more.

Your account

The financial data you enter

The accounts, transactions, transfers, budgets, categories, payees, tags, scheduled payments, and account logos you add or import. You provide all of it – no bank aggregator sits in the data path, so no outside company ever hands us a copy.

How you use the app

We keep a note of the days you opened the app – the date and nothing more – so we can tell whether Quidough is genuinely useful day to day. It's included in your data export, and you can delete it.

If you join the waiting list

Before launch, quidough.com lets you leave your email so we can keep you in the loop. That email is stored with our email provider (see sub-processors) as a waiting-list contact. We email you rarely – the occasional update, and the launch itself – and you can unsubscribe at any time from any message we send.

Technical data

Like any hosted service, our infrastructure records basic operational logs (such as IP address and request time) needed to run the service securely and reliably. We don't use these to build a profile of you or to track you across other sites.

3. What we deliberately don't collect or do

Some of these are conscious choices, stated plainly rather than hidden:

4. Why we use your data, and our legal basis

We use your data only to provide Quidough to you:

What forWhy it's lawful
Running your account and showing you your accounts, balances, budgets, and reportsPerformance of our contract with you
Sharing data within your household with the people you invitePerformance of our contract with you
Helping you when you report a problemPerformance of our contract, and our legitimate interest in supporting you
Keeping the service secure and working (operational logs)Our legitimate interest in a secure, reliable service
Emailing you if you joined the waiting list (occasional updates and the launch)Your consent
Understanding whether the app is useful (the dates you opened it)Our legitimate interest in improving the product

5. Who can see your data

This is where trust is won, so it's worth being completely straight.

Quidough is a paid, hosted service. That means your data lives on our servers and, like every mainstream finance app of this kind, the service can technically read it. We don't pretend otherwise.

In practice, we access your data only with your permission and only to help when you've reported a problem. We never browse it, and we never sell or share it. We don't offer the kind of encryption where "even we can't see it", because that wouldn't be true for an app that also shows you balances and reports.

Within your household, everyone you invite can see and edit every account, transaction, and budget in it – access is what membership grants. Owner labels are about organisation ("whose is this?"), not about locking anyone out. You choose who is in your household.

6. Who we share it with (sub-processors)

We don't sell or share your data. We do rely on a small number of trusted service providers to run Quidough, who process data only on our instructions and only to provide their service to us:

ProviderWhat they do for us
ResendSends our emails (waiting-list confirmation and the launch note)
Fathom AnalyticsPrivacy-focused, cookieless visitor statistics for this website
VercelHosts this website and the application
SupabaseApplication database, authentication, and secure file storage for your data

Where a provider processes data outside the UK, we rely on appropriate safeguards (such as Standard Contractual Clauses or the UK equivalent) to protect it. We may also disclose data if the law genuinely requires us to.

7. How we protect it

Your data is encrypted in transit and at rest, and access is tightly controlled. You sign in without a password – either with a one-time code sent to your email, or with your Google account – so there's no password to be guessed, leaked, or reused. Honestly, what encryption does is protect you from outside attackers and stolen backups – it does not mean we ourselves can't read your data, and we won't claim it does.

One thing to watch: when you export your data, the file is plain and readable – anyone who opens it can see everything in it. That's by design, so your data is genuinely yours and portable. Keep the file somewhere safe.

8. How long we keep it

9. Your rights

You can, at any time:

If you're in the UK and think we've handled your data poorly, you can complain to the Information Commissioner's Office (ICO). We'd rather you told us first at hello@quidough.com so we can put it right.

10. Children

Quidough isn't intended for anyone under 18, and we don't knowingly collect data from them.

11. Cookies and this website

quidough.com is a simple page: a value proposition, an email field, and a sign-in link. It runs no advertising and no cross-site tracking.

We do use Fathom Analytics to count visits and see which pages people read, so we can tell whether the site is working. Fathom is a privacy-focused service that doesn't use cookies and doesn't collect personal data or build a profile of you – so there's no tracking banner to click through. It never receives any of your financial data, which lives in the app, not on this page.

12. Changes to this policy

If we change how we handle your data, we'll update this page and move the "last updated" date. If a change is significant – and especially if we ever reconsidered any of the promises above – we'd tell you directly, not slip it in quietly.

13. Contact

Questions, requests, or concerns: hello@quidough.com, or write to Quidough, 483 Green Lanes, London N13 4BS, United Kingdom.
