Checkbook — Privacy Policy
Last updated: October 12, 2026
Checkbook is a manual financial register developed by McKittrick LLC, doing business as McKittrick Studios. Current versions of Checkbook contain no advertising, analytics, or tracking. This policy explains the app’s financial storage separately from Apple purchases, information you choose to send us, and this website.
Your financial information
Accounts, transactions, and bills you enter are stored locally on your device. When iCloud sync is enabled and available, that information syncs through Apple’s private CloudKit database in your own iCloud account, rather than a McKittrick-hosted financial database. We do not receive your financial register through that sync.
You can manage your records in Checkbook and your iCloud storage through Apple’s settings. Copies you export or share are separate from the app’s stored records: deleting an app record does not delete a CSV, email, or other copy you have shared. CSV import and export are not a complete backup or lossless restore.
App Store privacy disclosure
Checkbook’s App Store privacy label summarizes, under Apple’s definitions, the information collected from the app by us and any third-party partners. Starting with version 1.6.3, Checkbook includes no third-party advertising, analytics, or tracking SDKs, and we do not collect data from the app. The sections below describe Apple services, support communications, and this website separately from your financial records.
Earlier versions with ads
Checkbook versions before 1.6.3 showed banner ads to users without Pro, using Google Mobile Ads and Google’s User Messaging Platform for advertising consent. Those services could process information such as device identifiers, approximate location, and ad interactions; Checkbook never added your accounts, transactions, or bills to ad requests. Updating to the current version removes these services. See Google’s privacy policy for information Google may have processed.
Purchases through Apple
Apple handles App Store payments and purchase restoration. Checkbook uses Apple’s StoreKit purchase information to determine your Pro access. We do not receive your payment card details through Checkbook. Apple handles its account, billing, and payment information under Apple’s privacy policy.
Support and information you share
If you email support, we and the email services handling the message receive your email address, message, and any attachments you choose to send. We use that information to respond to your request and troubleshoot the issue. Do not send bank credentials, full account numbers, financial exports, or unredacted financial screenshots.
For questions or requests about support information you have sent us, contact privacy@mckittrick.co. This is separate from managing records on your device or in iCloud. Apple provides controls for information handled by its services; we cannot delete copies held in accounts or destinations you control.
This website
The McKittrick Studios website is hosted on Vercel and uses Vercel Web Analytics and Speed Insights to measure website visits and performance. Website requests and measurement can involve information such as the page visited, referring site, browser or device information, and performance measurements. This website measurement is separate from Checkbook’s iOS financial database and its App Store privacy label.
