Privacy policy

Effective date: 8 November 2026

Who we are: KLO Technical Services Limited, trading as KLO Development Services (company number 16105032), 23 Brook Road, Bomere Heath, Shropshire, SY4 3PU. Contact: [email protected].

This policy explains how the KLO Construction Programme app ("the App") handles information. In short: what you put into the App stays on your devices and in your own iCloud account, and what you put into the web page stays in your browser unless you send it to your iCloud. We cannot see it and we do not track you. To sell and check subscriptions we hold your email address and whether you are subscribed.

1. Your data stays with you

Everything you enter or attach (sites, programmes, plots, progress, delays, versions, client names, details and logos, and documents) is stored on your device. If you are signed in to iCloud, it is also kept in the App's private database in your own iCloud account, so that it syncs between your iPad and Mac. Apple stores it under your iCloud agreement with Apple. We have no access to it.

The client library and its logos are kept in a KLO folder in your own iCloud Drive, so that they sync between your devices. Other KLO apps you use with the same Apple ID can read and add to the same library. We have no access to it.

Once a day the App also saves a backup of each site you own that has changed, on that device only: Files › On My iPad › KLO Programme › Backups, or on a Mac the folder that Backups › Show backups in Finder opens. Backups are not synced and are not sent to us. A backup file you export yourself goes wherever you save or send it.

Your company's name and logo (Settings › Your company) are kept only on the device where you enter them. They are not synced.

Some of what you record may be personal data about other people, such as a client contact's name and phone number. For that information you decide what is recorded and why, so you are responsible for it under data protection law. We do not receive it.

2. Sharing a site

If you choose to share a site, it is shared through Apple's iCloud sharing with the people you invite. They can see the whole site and everything in it, and if you give them edit access they can change it. You can stop sharing at any time, and anyone you invited can leave the site.

When someone records progress, or a Last Planner constraint or commitment, on a shared site, the App stores with that change the identifier iCloud gives them and their name, as iCloud gives it on a shared site. Everyone on the site can see who made each change. The App says so to the owner before a site is first shared, and to each person the first time they open a site shared with them.

The names stay in the site's history after a person leaves it, until the person who shared the site erases them: Manage people › People who have left › Erase name. Their changes stay, shown as made by "Former member", on every device and in saved versions. Erasing needs no subscription, and it can't be undone. A backup keeps names as they were recorded. Erasing a name does not reach backups already made: delete those in Backups › Delete these backups….

3. Contacts

On an iPad, "Add from Contacts" in the client library opens Apple's contact picker. The App cannot see your contacts and does not ask permission to read them: the picker gives it only the one contact you pick, and the App copies that contact's details into the library. It sends your contacts nowhere.

4. App Lock and Face ID

If you turn on App Lock, your PIN is kept only on this device, in its keychain, as a salted one-way hash rather than the PIN itself. If you unlock with Face ID, the check is made by Apple's system; the App is told only whether it succeeded.

5. Problem reports

If you choose "Report a problem" (Settings › About), the App shows you the report and opens an email to us in your own mail app. The report contains the App version, your device model and operating system, how many sites, lines, plots, versions and delays you have, the iCloud sync status and any recent sync error. It does not contain the names of your sites, clients or people, or any of your programme. You can read it before sending, and nothing is sent unless you send it. We use it only to answer you and fix the problem, and we keep the email for as long as it takes to deal with it.

6. What we do not do

We do not collect analytics, track you, or show advertising.

We do not sell your information. We share it only with the service providers named in this policy, to run the App, the web page and your subscription.

We do not receive your sites or programmes. Our only server for subscriptions holds your KLO account (section 7).

7. Subscriptions

What it gives. Without a subscription you can open, read, print and export every site. Making any change needs a subscription: £39 a month or £390 a year, prices including VAT. One subscription covers the App on iPad and Mac and the web page, and each person on a shared site has their own.

App Store. A subscription bought in the App is sold, renewed and cancelled by Apple, under your agreement with Apple. Apple tells the App whether it is active. We never see your card or bank details. Manage or cancel it in your Apple Account's Subscriptions settings.

Your KLO account. To subscribe on the web page, or to use one subscription in both the App and the web page, you use a KLO account. It holds your email address, a sign-in token and your subscription state (active, until when, bought on the web or through Apple). It is kept on our account server, run on Cloudflare (Cloudflare D1, Western Europe). Sign-in codes are emailed to you through Microsoft 365, from [email protected]. If you sign in to it in the App, the App tells the server about your App Store subscription, so that the web page unlocks too. We use the account only to sign you in and decide whether editing is open. Lawful basis: contract. You can delete it in the App (Settings › Subscription › Delete KLO account) or by emailing us.

Paying on the web. Web payments are taken by Stripe. Your email address, card details and billing address go to Stripe, and we receive your Stripe customer reference and subscription dates. Stripe's privacy policy: https://stripe.com/privacy.

8. Deleting your data

With a subscription you can delete any of your sites. Deleting one on one device deletes it from your iCloud copy and your other devices, and from the devices of anyone you shared it with. Leaving a site someone shared with you needs no subscription, and removes it from your devices only.

Deleting a site does not delete its backups on that device: delete them in Backups › Delete these backups…. Deleting the App from an iPad deletes its backups there; on a Mac they stay in that folder until you delete them.

To remove everything, with or without a subscription, delete the App from your devices and delete its data from iCloud. On an iPad, go to Settings › [your name] › iCloud › Manage Account Storage. On a Mac, go to System Settings › [your name] › iCloud › Manage.

9. Your rights

Under UK data protection law you have rights over personal data that we hold about you. The personal data we hold about you is your KLO account (section 7), if you have one, and any email you send us. To exercise your rights, contact [email protected]. You can also complain to the Information Commissioner's Office at ico.org.uk.

10. Children

The App is a business tool for people who plan and run construction sites. It is not intended for children.

11. Changes to this policy

If we change this policy, we will update the effective date above. If a change affects what the App does with your information, we will say so in the App Store release notes for that version.
