Runway — Privacy Policy

Version 5 · Last updated: 18 October 2026

In short: Runway has no accounts and no server. Your figures stay on your phone. We do not collect, receive or store any of your personal data.

1. Who we are

Runway is made by Ethan Greer, an individual developer in the UK ("we", "us"). Contact: ethangreer4@gmail.com.

2. What stays on your phone

Everything you enter in Runway stays on your phone: accounts, balances, contributions, budget, goals, retirement and tax settings, and home-purchase figures. The app encrypts them with AES-256 and keeps them in your phone's secure store (the iPhone Keychain or the Android Keystore). The encryption key and your recovery code are also kept only on your phone.

We never receive these figures. We cannot see them, and we cannot recover them for you.

If you turn on Face ID, fingerprint or another phone unlock, your phone handles it. Runway never receives your face or fingerprint data.

3. What leaves your phone

• Backup files that you export. When you tap Export backup, the app makes an encrypted file and opens your phone's share sheet. You choose where the file goes, for example Files, iCloud Drive, Google Drive or email. The file opens only with your recovery code. We never receive it.
• Public rates. The app downloads the Bank Rate and quoted mortgage rates from the Bank of England, and inflation figures from the Office for National Statistics. These requests contain none of your figures. Like any website, those bodies receive your phone's IP address.
• Links that you open. Links to GOV.UK, your bank or pension provider, and this page open in your browser. The website you open receives your IP address.
• App stores. Apple and Google supply the app. If you allow it in your phone's settings, they can share anonymous crash and usage statistics with us. Their own privacy policies apply.

4. What we do not do

• We do not have accounts, a server or a database for your data.
• We do not use analytics, advertising or tracking tools, and we do not show ads.
• We do not sell or share your data, because we do not have it.
• Runway does not connect to your bank or broker. It cannot trade, move money or make payments.

5. Connected services

Runway connects to no bank, broker or other financial service at this time. Before Runway connects to a service, we will update this policy and tell you in the app first. The connection will be optional.

6. Deleting your data

To delete all your figures, go to Settings › Delete all data, or delete the app. Backup files that you exported stay where you saved them, until you delete them.

7. Your rights and complaints

Under UK data protection law you have rights over your personal data. Because we hold none, there is nothing for us to give, correct or delete. If you have a question or a complaint, email us. You can also complain to the Information Commissioner's Office: ico.org.uk/make-a-complaint, telephone 0303 123 1113.

8. Children

Runway is for adults in the UK. It collects no data from anyone, including children.

9. Changes to this policy

If Runway changes how it uses data, we will update this policy first. The version number and date at the top change each time. If a change is important, we will tell you in the app before it takes effect.
