Register Book Terms of Use
Effective date: November 12, 2026
These terms are for the app Register Book, published by XD3V. They cover Register Book on iPhone, iPhone Duo and iPad. They are the whole terms for the app. The website xd3v.com has separate terms, the Terms of Use for the website.
1) The license
You get Register Book from Apple’s App Store. Your use of the app is governed by Apple’s Licensed Application End User License Agreement, the standard license for App Store apps. Sections 2 to 4 below add to that license. They do not replace it.
2) Price
Free to download. Full use for 30 days. Then a one-time $4.99 unlock. No subscription.
Apple handles each purchase and each refund through the App Store.
3) Your records are yours to keep correct
- Register Book is a tool for your own record-keeping. You enter each item yourself, and the app does the arithmetic.
- The app is not a bank service. It does not connect to your bank, and it cannot tell what your bank has recorded. Your bank’s records decide what your balance is.
- The app does not give financial, tax, accounting or legal advice.
- Your records are stored on your device and in your own iCloud. Keep a backup. The app saves one every day, and you can export your records at any time.
4) Support
For help, write to support@xd3v.com. See also the Support page.
5) Privacy
The Register Book Privacy Policy says how the app handles information. In short: the app does not collect any data.
6) Changes to these terms
If these terms change, the new version is posted on this page with a new effective date.
