1. Introduction
Welcome to Chronix ("we," "our," or "us"). This privacy policy explains how we collect, use, and protect information when you use our Android application (the "App"). By using Chronix, you agree to the practices described in this policy.
2. Information We Collect
Chronix is designed to work locally on your device. We collect the following categories of information:
2.1 Calendar Data
Chronix requests read-only access to your device calendar (READ_CALENDAR permission) solely to
allow you to import events as countdowns. Calendar data is processed on-device and is not
transmitted to any external server.
2.2 Notification Data
The App may send local notifications to remind you of upcoming countdowns
(POST_NOTIFICATIONS permission). Notification content is generated locally from data you create
within the App.
2.3 Device & Usage Data
When you install or use Chronix, we may automatically collect limited technical information, including:
- Device model, operating system version, and screen size
- App version and crash logs
- Basic usage analytics (e.g., screens visited, feature interactions)
This data is anonymized and used solely to improve App quality and user experience.
2.4 Data Stored Locally
Your countdown events, preferences, widget configurations, and theme settings are stored locally on your device using Android's SharedPreferences and internal storage. This data does not leave your device unless you explicitly enable a sync or backup feature.
3. How We Use Your Information
We use the information collected for the following purposes:
- Provide core functionality — creating, displaying, and managing countdowns
- Calendar import — reading calendar events to add as countdowns
- Reminders — scheduling and delivering local notifications
- Widgets — displaying countdown data on your home screen
- App improvement — analyzing anonymized usage data to fix bugs and enhance features
- Compliance — fulfilling legal obligations where applicable

5. Data Sharing & Third-Party Services

- Analytics — anonymized usage statistics to improve the App
These third-party services have their own privacy policies. We encourage you to review them. No calendar data or countdown content is shared with third parties.
6. Data Security
We take reasonable measures to protect your information. All data is stored locally on your device. We do not operate servers that store user data. Network connections (if used) are encrypted via TLS. However, no method of electronic storage is 100% secure.
7. Data Retention
Your data remains on your device as long as you have the App installed. You may delete your data at any time by uninstalling the App or clearing its data from Android Settings. Anonymized analytics data may be retained in aggregated form for analytical purposes.
8. Children's Privacy
Chronix is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete such information.

- Access — request a copy of the data we hold about you
