Does my statement get uploaded?

No. KnowYourSpend reads it on your phone, or in your browser if you use the web version. Amounts, dates, balances and account numbers stay on your device. What can leave is the name of a shop the app doesn't know, so it can look up the owner; filters hold back names that look like a person or something sensitive. You can switch look-ups off in Settings → Shops we don't know.

How do I get a statement from my bank?

In your banking app or online banking, look for Statements, choose a month, and save it as a PDF, or export your transactions as a CSV. The app's + button has step-by-step guides for 13 banks, including Monzo, Starling, Revolut, Barclays, Lloyds, NatWest, Nationwide and Santander.

A shop has the wrong country. What can I do?

Tap the shop in the report and choose "Which country is this?" to set it yourself; your choice stays on your phone. Please also tell us at hello@knowyourspend.org so we can look into it and fix it for everyone.

What does "Estimated" mean?

For a shop we can't link to an owner, the app counts it under the country where you paid, read from the country code, town or web address your bank prints. A small café in Lewisham is almost always UK-owned. You can switch estimates off in Settings.

What do "Checked", "Matched" and "Unverified" mean?

How sure we are about the owner. Checked: a person verified each step. Matched: worked out from official company identifiers that agree, or found by name in an open dataset. Unverified: a best guess, often from AI, labelled so you can tell.

Do I need to install anything?

No. KnowYourSpend runs in your phone's browser. To open it like an app, add it to your home screen: in Safari tap Share, then "Add to Home Screen"; in Chrome choose "Install app" or "Add to Home screen". That also helps your browser keep your data, which lives on your phone. Saving an encrypted backup (Settings → Back up or move your data) or an encrypted copy in an optional account (Settings → Your account) gives you a copy you control.

Can I keep my results?

Yes. Tap "Email me my results" to send yourself the percentages and the well-known shops you pay most (never amounts, dates or balances). No account needed; we use your address to send that email and don't keep it unless you ask for updates. To open your data on another phone or computer, sign in with your email in Settings → Your account and choose a passphrase. Your data is encrypted with it on your device before it's saved, so we can't read it, and if you forget the passphrase we can't recover it.

How do I delete my data?

Settings → Delete all my data. Your data is on your device, so that deletes the app's copy of it, including any temporary copies of files you picked. Deleting the app, or clearing the site's data in your browser, does the same. Backups you saved elsewhere stay where you put them. If you made an account, Settings → Delete my account deletes it and its encrypted copy.

Is it free?

Yes. There are no ads and no in-app purchases, and you don't need an account.
