Question 1

What is Chessify?

Accepted Answer

Chessify is a chess opening trainer that helps you memorize and practice your repertoire. Import your PGN files, and Chessify will quiz you on the moves, track your accuracy, and help you identify weak spots in your preparation.

Question 2

How do I add openings to practice?

Accepted Answer

Go to the Openings page and click "New Opening". You can paste PGN text directly or import a .pgn file. Chessify will automatically extract all the lines and variations for training.

Question 3

Do I need an account to use Chessify?

Accepted Answer

No! Chessify works completely offline without an account. All your data is stored locally on your device. Creating an account is only needed if you want to sync your repertoire across multiple devices.

Question 4

What are the different training modes?

Accepted Answer

There are three modes: Random (lines shuffled for true recall testing), Structured (lines grouped by variation for systematic learning), and Priority (weak lines first based on your mistake history).

Question 5

What is Perfect Mode?

Accepted Answer

Perfect Mode requires you to complete every line without mistakes. If you make an error, the line restarts from the beginning. It's great for building muscle memory and ensuring you truly know each variation.

Question 6

How does the priority system work?

Accepted Answer

Chessify tracks your accuracy on each line. Lines where you make more mistakes are weighted higher in Priority mode, so you spend more time on the variations that need work.

Question 7

Where is my data stored?

Accepted Answer

By default, all your data (openings, training history, settings) is stored locally in your browser using IndexedDB. This means it works offline and your data stays on your device.

Question 8

What happens if I clear my browser data?

Accepted Answer

If you clear your browser data or uninstall the PWA, your local data will be lost. If you have an account with sync enabled, you can restore your data by signing in again.

Question 9

Can I export my openings?

Accepted Answer

Yes! You can export any opening back to PGN format. This is useful for backups or transferring your repertoire to other chess software.

Question 10

What features require a subscription?

Accepted Answer

The core training features are free. A subscription unlocks cloud sync across devices, advanced statistics, and priority support. Check our pricing page for current plans.

Question 11

Can I cancel my subscription?

Accepted Answer

Yes, you can cancel anytime. Your subscription will remain active until the end of the current billing period. After that, you'll still have access to free features.

Question 12

What happens if I delete my account?

Accepted Answer

Deleting your account is permanent and cannot be undone. All your data will be removed, including your openings, training lines, training history, and statistics. If you have an active Pro subscription, it will be canceled immediately without a refund. Your local data on other devices will remain until you clear it manually.
