Caliber privacy policy

For the Caliber: Watch Collection app (iPhone, iPad & Mac) · Last updated 26 June 2026

Summary. Your watch collection is stored on your device and, if you use iCloud, synced across your own Apple devices through Apple’s private iCloud database — which only you can access. Caliber transmits nothing to Whiteforge. There is no Whiteforge account, no analytics, no advertising, and no third-party SDKs of any kind.

1. Introduction

This policy explains how Caliber handles your data. Caliber is an app for iPhone, iPad and Mac published by Whiteforge Technologies Ltd (“Whiteforge”, “we”), a company registered in England and Wales (company number 17224707). It is a collection and service-history tracker for mechanical watches.

This policy is for the Caliber app. The whiteforgetech.co.uk website has its own privacy policy.

2. Data Whiteforge receives

None. Caliber does not transmit any data to Whiteforge. There are no Whiteforge servers in the data path. The app contains no analytics SDKs, no crash-reporting SDKs, no advertising SDKs, and no third-party tracking libraries of any kind.

3. What is stored on your device

Everything you enter in Caliber is stored on your device using Apple’s on-device database (SwiftData). This includes your watches and their details, service history, timing readings and position sets, wear logs, straps and bracelets, the photos you attach, and any documents you import. You can edit or delete any of it at any time from within the app, and removing the app removes the local copy.

4. iCloud sync

If you are signed in to iCloud, Caliber keeps your collection in sync across your own Apple devices using Apple’s CloudKit. Your data is stored in your private iCloud database — the same personal iCloud storage your other apps use — under your own Apple Account. Only you have access to it. Whiteforge cannot see this data and has no access to it; it is governed by Apple’s privacy policy. If you sign out of iCloud or disable iCloud for Caliber, the app continues to work using only the copy stored on that device.

5. Network activity

Apart from the iCloud synchronisation described above — which goes only to Apple’s servers, on your behalf and under your Apple Account — Caliber makes no network connections. It contacts no Whiteforge servers and no third parties. The app is fully usable offline.

6. Purchase

Caliber is free to download and try, with a one-time in-app purchase to unlock the full app. When you buy through the App Store, Apple processes the payment and Whiteforge does not receive your payment details; this is governed by Apple’s privacy policy. The Mac version can also be bought as a direct download from this website, in which case checkout and licensing are handled by our reseller, Lemon Squeezy, who processes the payment; Whiteforge does not receive or store your card details. Lemon Squeezy’s handling of your data is governed by its own privacy policy.

7. Third parties

Caliber contains no third-party SDKs. All frameworks used are Apple’s own system frameworks (including SwiftUI, SwiftData, CloudKit and Swift Charts).

8. Children

Caliber is a specialist tool intended for watch collectors and watchmakers. It is not directed at children. We do not knowingly collect personal information from children under 13.

9. Your rights

If you are in the UK or the EU, you have rights under the UK GDPR and the EU GDPR. Because Caliber stores your data on your own device and in your own private iCloud, and transmits nothing to Whiteforge, there is no personal data held by us that is subject to these rights. Data held in your iCloud is subject to your rights with Apple. You can complain to the UK Information Commissioner’s Office at ico.org.uk.

10. Changes to this policy

If we change this policy we will update the “Last updated” date at the top. Material changes will be summarised at the top of the policy for a reasonable period.
