Privacy policy

Last updated 15 November 2026

The Keyfisher app has no accounts, no adverts and no tracking. It does not send us anything about you. Your progress stays on your phone.

Who is responsible

Keyfisher is made and run by Dave Holliday, who is the data controller for the purposes of UK data protection law.

This policy covers the Keyfisher app for iPhone and iPad and the website at keyfisher.com.

The app

What we collect

Nothing. The app does not ask for your name, email address, location, contacts, photos or any other personal information, and it does not contain analytics, advertising or tracking software. It does not connect to any server of ours.

What stays on your device

The app saves your progress on your device: which boxes you have opened, the position of each box’s parts, your move counts and how many hints you have left. We cannot see it. If you back up your phone, this file is included in your backup. Deleting the app deletes it.

Purchases

The subscription and hint packs are sold by Apple through the App Store. Apple takes the payment and holds your payment details; we never receive them. The app asks Apple whether your subscription is active so it can unlock boxes. Apple sends us sales reports that do not identify you. Apple’s handling of your information is described in Apple’s privacy policy.

The website

keyfisher.com has no cookies, no analytics, no adverts and no sign-up forms. Two companies are involved in showing you the pages, and each necessarily receives your IP address and basic details about your browser when it does so:

• Cloudflare hosts the site and keeps short-lived technical logs to deliver it and protect it from abuse. See Cloudflare’s privacy policy.
• Google Fonts supplies the typefaces, which your browser fetches directly from Google. See Google’s privacy policy.

Both companies operate worldwide, so this information may be processed outside the United Kingdom. Our legal basis for using them is our legitimate interest in running a working, secure website.

If you email us

If you write to us, we receive your email address and whatever you put in your message. We use it only to reply and to deal with what you raised, on the basis of our legitimate interest in answering people who contact us. Messages are held by the provider of our mailbox and deleted within two years of our last reply, unless we need to keep one longer to deal with a legal claim.

Sharing

We do not sell personal information or share it for advertising. We would disclose information only if the law required it.

Children

Keyfisher is suitable for all ages, and because the app collects no personal information, it collects none from children. If you believe a child has emailed us personal information, tell us and we will delete it.

Your rights

Under UK and EU data protection law you can ask us for a copy of any personal information we hold about you, ask us to correct or delete it, and object to or ask us to restrict how we use it. In practice the only information we could hold is email you have sent us. To use any of these rights, email [email protected]. There is no charge.

If you are unhappy with how we have handled your information, you can complain to the Information Commissioner’s Office in the UK, or to the data protection authority where you live.

Changes to this policy

If the app or the website starts handling information differently, we will update this page and change the date at the top before the change takes effect.
