BookMaster collects zero personal data. Everything stays on your device. We can't access your reading data because it never leaves your iPhone.
Our Privacy Philosophy
At DigTek, privacy isn't a feature—it's the foundation. BookMaster is designed with a simple principle: your reading data belongs to you.
In an age where most apps collect, analyze, and monetize your personal data, we've chosen a different path. BookMaster operates with complete privacy by design, not as an afterthought.
What We Don't Collect
The easiest way to protect your privacy is to not collect data in the first place. Here's what BookMaster will never collect:
- Your reading progress or book titles
- Reading habits or patterns
- Device identifiers or location data
- Analytics or usage statistics
- Crash reports or error logs
- Email addresses or account information
- Any personal information whatsoever
How Your Data Stays Private
Local Storage Only
Every piece of reading data you enter into BookMaster is stored locally on your device using Apple's secure SwiftData framework. This data never leaves your iPhone, iPad, or Mac.
No Network Connections
BookMaster doesn't connect to the internet for any reading-related functionality. No data transmission means no data collection.
No User Accounts
There are no accounts to create, no passwords to remember, and no profiles to manage. Without accounts, there's nothing for us to link your data to.
No Analytics
We don't use analytics frameworks like Google Analytics, Facebook SDK, or any third-party tracking tools. Your app usage patterns remain completely private.
Data You Control
You have complete control over your reading data:
- Export Anytime: Export all your data in CSV, Markdown, or JSON format
- Delete Anytime: Remove individual books or all data with simple swipe gestures
- No Lock-in: Your data is yours to keep, move, or delete as you choose
Your reading data should never be held hostage by an app. BookMaster's export feature ensures you can always access your reading history, even if you stop using our app.
Technical Implementation
Our privacy-first approach is built into the app's architecture:
- SwiftData Storage: Uses Apple's local database framework with device-level encryption
- No Network Layer: The app contains no code for transmitting data externally
- Minimal Permissions: Requests only essential iOS permissions for core functionality
- Secure Exports: Data exports use iOS native sharing without intermediate servers
What Data Does Live on Your Device
To provide the reading tracking functionality, BookMaster stores this information locally on your device:
| Data Type | Stored Locally | Sent to Servers |
|---|---|---|
| Book titles and authors | Yes | Never |
| Current and total pages | Yes | Never |
| Reading session dates and notes | Yes | Never |
| Progress statistics | Yes | Never |
Third-Party Services
BookMaster doesn't integrate with any third-party services, analytics platforms, or advertising networks. The app operates completely independently.
Updates to This Policy
Our commitment to privacy won't change. If we ever need to update this policy, we'll clearly communicate any changes and maintain our privacy-first principles.
Last updated: September 11, 2025
We will never compromise your privacy for business metrics, advertising revenue, or growth hacking. Your reading journey is personal, and it stays that way.

The Bigger Picture
BookMaster represents our belief that useful software doesn't require surveillance. By keeping everything local, we create a trust relationship with users: we provide functionality, you keep your privacy.
This isn't just good for users—it's good business. Privacy-focused design eliminates data breach risks, reduces compliance overhead, and creates software that users can trust completely.
