PRIVACY POLICY - dtCalendar
Effective Date: 17-Apr-2026
Last Updated: 07-Jun-2026
Digital Traditions ("we", "us", "our") built the dtCalendar app ("the App") as a free application. This page informs users ("you") of our policies regarding the collection, use, and disclosure of personal information.
Information We Collect
Location Data
The App requests access to your device's location (fine and coarse) to:
- Determine your geographic coordinates for calculating sunrise/sunset times and panchangam (Tamil calendar) data
- Identify your country and region for displaying locally relevant public holidays
Location data is processed entirely on your device. We do not transmit, store, or share your location with any server or third party.
Notification Permissions
The App requests notification permissions to deliver panchangam event alerts (e.g., Raaghu Kalam, Yamagandam, Gulikai, and festival reminders such as Pournami, Ekadasi, and Pradosham) that you configure. Notification preferences are stored locally on your device.
Home Screen Image
You may optionally choose a personal photo as your home screen background from your device's gallery via the Android Photo Picker. The selected image is copied to the App's private storage on your device and is never uploaded, transmitted, or shared with Digital Traditions or any third party. The App does not request the broad storage or camera permissions — only the Photo Picker's single-image grant.
Permissions We Request
For full transparency, here is every permission the App requests and why:
- Location (fine and coarse) — to calculate sunrise/sunset and panchangam times for your position, and to show locally relevant public holidays. Used on-device only.
- Notifications — to deliver the panchangam and festival alerts you enable.
- Exact alarms — to fire those alerts at the precise times they are scheduled for.
- Run at startup — to restore your scheduled alerts after the device restarts; without it, your alerts would be lost on every reboot.
- Photos (Android Photo Picker) — only if you choose a personal home screen background. A single image you pick is copied to the App's private storage; the App does not request broad photo, storage, or camera access.
- Internet — included because Google Play Services (used for on-device location) requires it. dtCalendar does not use the internet connection to transmit your personal data — see "Information We Do NOT Collect" below.
Information We Do NOT Collect
- We do not collect personal information (name, email, phone number)
- We do not collect analytics or usage data
- We do not use tracking technologies, cookies, or advertising identifiers
- We do not transmit any data from your device to external servers
- We do not use third-party analytics, advertising, or data-processing services
Data Storage
All data (user preferences, notification rules, location cache) is stored locally on your device using Android's standard storage mechanisms (DataStore, Room database). No data is synced to the cloud or backed up to external services.
Third-Party Services
The App does not integrate with any third-party services that collect user data.
The App uses Google Play Location Services solely for on-device location determination. Please refer to [Google's Privacy Policy](https://policies.google.com/privacy) for information about how Google handles location service requests at the platform level.
Children's Privacy
The App does not knowingly collect information from children under 13. The App does not require any personal information to function.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. Continued use of the App after changes constitutes acceptance.
