Frequently Asked Questions
Does the extension work offline?
The extension caches contest data so you can view upcoming contests offline. However, fetching the latest contest updates and adding events to your calendar requires an internet connection.
How often is contest data updated?
Contest data is refreshed automatically every few hours. You can also manually refresh by clicking the refresh button in the extension popup.
Is my data private and secure?
Absolutely! We do not sell or share your data. Your preferences are stored locally on your device. For Google Calendar integration, we only access your calendar to add contest events you explicitly choose to sync. Read our Privacy Policy for more details.

Contest Reminder is currently available for Google Chrome and Chromium-based browsers (Edge, Brave, Opera, etc.) via the Chrome Web Store.
