Terms of use

Last updated 11 October 2026

Draft for legal review — not yet published

These terms apply when you use the KnowYourSpend app or website. By using them you agree to these terms. If you don't agree, please don't use KnowYourSpend.

KnowYourSpend is provided by KnowYourSpend Ltd, registered in England and Wales ([company number to follow]), [registered office to follow] ("we"). Contact: hello@knowyourspend.org

1. Who can use KnowYourSpend

You must be 18 or over and use KnowYourSpend for your own personal, non-commercial purposes.

2. What KnowYourSpend does

KnowYourSpend reads bank statements and receipts that you choose, on your device, and estimates which companies ultimately own the businesses you paid and which countries those companies are based in.

3. Estimates, not advice

4. Brand names

Brand and company names are used only to identify the businesses on your statement. KnowYourSpend is not affiliated with, endorsed by, or sponsored by any of them.

5. Your data and your device

Your statements and the data the app finds stay on your device (see our Privacy notice). Because we never receive them in a form we can read, we can't recover them if your device is lost, reset or the app is deleted. Use the encrypted backup in Settings, or an optional account, if you want a copy. Both are encrypted with a passphrase only you know: keep it safe, as we can't reset it or open your data without it.

If you make an account, keep access to your email address, which is how you sign in. You can delete your account at any time in Settings. We may close an account that is used to abuse the service, and we'll tell you first where we can.

6. Sharing results

The app can make a share card showing your percentages by country. You choose whether to share it and where. Please don't edit a card to show something the app didn't calculate, or add statements about companies that you can't support. You are responsible for what you post.

7. Fair use

Please don't:

We may limit or stop access to the look-up service for anyone who does.

8. Open data

KnowYourSpend uses open data: OpenStreetMap's name-suggestion-index (BSD-3-Clause), Wikidata (CC0), GLEIF (CC0), GeoNames (CC BY 4.0) and Companies House data (Open Government Licence). The method page in the app gives full attributions.

9. Changes and availability

KnowYourSpend is free. We may change, suspend or stop it, or these terms. If we change these terms in a way that matters, we'll tell you in the app first.

10. Our responsibility to you

11. Law

These terms are governed by the law of England and Wales. You can bring a claim in the courts of England and Wales, or, if you live in Scotland or Northern Ireland, in your local courts.
