Register Book Privacy Policy
Effective date: November 12, 2026
This policy is for the app Register Book, published by XD3V. It covers Register Book on iPhone, iPhone Duo and iPad. It is the whole privacy policy for the app. The website xd3v.com has a separate policy, the Privacy Policy for the website.
1) Summary
Register Book does not collect any data. XD3V receives nothing from the app: no records, no contact details, no identifiers, and no usage information.
2) Where your records are kept
- The accounts, transactions and other records you enter are stored on your device.
- If you use iCloud, your records are also stored in your own iCloud account, so that your devices stay in step. Apple provides that storage under your agreement with Apple.
- XD3V cannot see or reach your records, on your device or in iCloud.
- The app saves a backup file on your device every day. That file stays under your control.
3) What the app does not do
- It does not connect to your bank, and it never asks for a bank login.
- It has no ads.
- It has no analytics tools and no third-party tracking code.
- It does not ask you to create an account.
- It does not sell or share data, because it has none to sell or share.
4) Features that use your device
- Import from screenshots. When you bring a register in from screenshots, the app reads the pictures on your device. The pictures and the text in them do not leave your device.
- Siri and Shortcuts. If you add an entry or ask for a balance with Siri, Apple handles your request under Apple’s privacy policy. XD3V does not receive it.
- Widgets. The widgets show your balance on your own device. If the app’s lock is on, they show no amounts.
- Face ID. The lock uses Face ID through iOS. The app does not receive or store your face data.
5) Purchases
Purchases are handled by Apple through the App Store. XD3V does not receive your name or your payment card details.
6) Support
If you write to support@xd3v.com, XD3V receives your email address and whatever you choose to say. XD3V uses it only to answer you.
7) Children
The app is not directed to children under 13. It collects no data from anyone.
8) Deleting your records
Your records are under your control. To remove them, delete them in the app, or delete the app and its iCloud data in the Settings of your device.
9) Changes to this policy
If this policy changes, the new version is posted on this page with a new effective date. If the app ever starts to collect data, this policy will say so before that version of the app is released.
