School Timetable Generator Effective Date: March 2026 Last Updated: March 3, 2026
This Privacy Policy describes how School Timetable Generator ("we", "us", "our", or "the App") collects, uses, and protects your information. By downloading, installing, or using the App, you agree to the practices described in this policy.
The App allows you to enter school-related data such as school names, teacher names, class names, subject names, schedule configurations, and timetable preferences. This data is stored entirely on your device and is never transmitted to our servers.
To improve the App and understand how it is used, we automatically collect certain anonymous usage data through third-party services:
Usage Analytics: Screen views, feature usage patterns (e.g., which features are used most often, generation mode selected, number of classes/subjects configured), and general interaction events. This data does not include any personal information, school names, teacher names, or schedule content.
Crash Reports: If the App encounters an error, anonymous crash data (device model, operating system version, stack trace) is collected to help us identify and fix issues.
Device Information: General device type, operating system version, and language settings. This is collected anonymously and cannot be used to identify you personally.
Advertising Data: For free-tier users, the App displays advertisements through Google AdMob. AdMob may collect device advertising identifiers and usage data in accordance with Google's privacy practices. Premium subscribers do not see advertisements.
We do not collect, store, or transmit:
Your name, email address, phone number, or any personal contact information
School data, teacher names, class names, subject names, or timetable content
Location data (GPS, Wi-Fi, or network-based)
Contacts, photos, camera, microphone, or any on-device files
Passwords or authentication credentials
We use the automatically collected anonymous data to:
Improve the App: Understand which features are most used and identify areas for improvement
Fix Issues: Diagnose and resolve crashes and bugs
Understand Usage Patterns: Analyze aggregate trends such as common schedule configurations, popular modes (student vs. admin), and export preferences
Display Advertisements: Serve relevant ads to free-tier users through Google AdMob
Manage Subscriptions: Process premium subscription purchases through Google Play Billing

All timetable data you create (teachers, classes, subjects, schedules, configurations) is stored locally on your device in an application database. This data never leaves your device and is not accessible to us or any third party.
We do not operate any servers or cloud storage. No user-generated content is uploaded, synced, or backed up to any external service.
Local data remains on your device until you clear the App's data, uninstall the App, or reset your device.
Analytics data is retained by Firebase according to Google's data retention policies (typically 14 months for event data).
Crash data is retained by Firebase Crashlytics for 90 days.
The App displays advertisements through Google AdMob. AdMob may use your device's advertising identifier to serve relevant advertisements. You can opt out of personalized advertising by adjusting your device settings:
Go to Settings > Google > Ads > Opt out of Ads Personalization (on Android)
Premium subscribers enjoy a completely ad-free experience. No advertisements are displayed, and no advertising-related data is collected while you have an active premium subscription.
Premium subscriptions are managed entirely through Google Play Billing. We do not collect, process, or store any payment information (credit card numbers, billing addresses, etc.). All payment processing is handled by Google. For information about how Google handles payment data, please review the Google Payments Privacy Notice.
You can manage or cancel your subscription at any time through the Google Play Store:
Open Google Play Store > Profile icon > Payments & subscriptions > Subscriptions
The App is designed for school administrators, teachers, and students of all ages. We do not knowingly collect personally identifiable information from anyone, including children under the age of 13 (or applicable age in your jurisdiction).
Since the App does not collect personal information, register users, or require sign-in, there is no mechanism through which personal data from children could be collected.
If you are a parent or guardian and believe your child has somehow provided personal information through the App, please contact us at the details below, and we will take steps to address the concern.
The App requests the following Android permissions:

Purpose
INTERNET

The App does not request access to your contacts, camera, microphone, location, storage (beyond its own app-specific storage), or any other sensitive permissions.
You have the following rights regarding your data:
Delete Local Data: You can clear all app data at any time by going to Android Settings > Apps > School Timetable Generator > Storage > Clear Data. This removes all locally stored timetable data permanently.
Opt Out of Personalized Ads: Adjust your advertising preferences in Android Settings > Google > Ads.
Opt Out of Analytics: You can limit analytics collection by disabling usage and diagnostics sharing in your device settings.
Uninstall: Uninstalling the App removes all locally stored data from your device.
Cancel Subscription: You can cancel your premium subscription at any time through the Google Play Store without any penalty.
The App is available worldwide and is designed to support international school calendars, right-to-left languages (Arabic, Dari, Pashto, Farsi, Urdu), and various scheduling configurations. Regardless of your location, the same privacy practices apply: your timetable data stays on your device, and only anonymous usage analytics are collected.
We may update this Privacy Policy from time to time to reflect changes in the App, our practices, or applicable laws. When we make changes, we will update the "Last Updated" date at the top of this policy. We encourage you to review this policy periodically.
For significant changes, we will notify users through an in-app notice or an update to the App's store listing.
