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.
What browsers are supported?
Contest Reminder is currently available for Google Chrome and Chromium-based browsers (Edge, Brave,
Opera, etc.) via the Chrome Web Store.
How do I report a bug or request a feature?
We welcome feedback! Please email us at dev.aakash.tools@gmail.com with bug reports, feature requests, or
general questions.
How does auto-sync to Google Calendar work?
Once enabled in the settings, the extension automatically syncs contests from your selected platforms
to your Google Calendar. You must visit the extension at regular intervals for the sync to occur.
Latest from our Competitive Programming Blog
Between LeetCode, Codeforces, AtCoder, and CodeChef, keeping track of coding contests has become a
job itself. Here is why you need a dedicated tool to manage the chaos.
If you are a competitive programmer or a software engineer preparing for interviews, you already know
the struggle. There are simply too many platforms. On any given weekend, there might be a Codeforces
Div 2 round, an AtCoder Beginner Contest, a LeetCode Weekly Contest, and a CodeChef Starter block.
Keeping track of these manually is a recipe for missed opportunities.
We built the Contest Reminder Chrome Extension precisely to eliminate this friction. Instead of
manually checking multiple websites, the extension does the heavy lifting for you: Centralized
Dashboard, Google Calendar Sync, and Smart Notifications.
Using ChatGPT to solve LeetCode problems guarantees you will fail your technical interviews. But
using it as a personalized tutor can hyper-accelerate your algorithm learning.
The truth? AI is the greatest personalized DSA tutor ever invented, but only if you use it correctly.
If you just copy and paste prompts to get the green "Accepted" checkmark, you are robbing yourself
of the learning process.
Do Not Ask for the Solution. Ask AI to Review Your Time Complexity. Use the "Explain Like I am 5"
Protocol. Ask for Alternative Approaches.
With LLMs writing perfect boilerplate code in seconds, do software engineers still need to grind Data
Structures and Algorithms? The short answer: Yes, more than ever.
While the act of writing code has been commoditized, the ability to think computationally has not.
LLMs don't know the exact constraints of your novel business problem. You need DSA knowledge to ask
the AI the right questions and verify architecture.
Building a consistent habit is arguably more important in competitive programming than raw
intelligence. The LeetCode Daily Challenge provides a structured way to practice, but treating it
like a chore won't yield the results you want.
A diverse problem set prevents algorithmic myopia, a trap where you only know how to solve problems
using your favorite data structure.
The most critical factor in improving your rating is upsolving. Participating in a contest only tests
what you currently know. Upsolving (solving the problems you failed to solve during the contest) is
how you learn what you don't know.
Everything you need to know about the LeetCode Weekly and Biweekly contest schedule for 2026, including exact times, format, rating system, and preparation tips.
