Frequently asked questions

How does the review schedule work?

LeetReviewer uses the FSRS spaced-repetition algorithm. After each review you tell us how confident you felt — Shaky, Okay, or Solid — and the scheduler picks the next review date so you see the problem again right around the moment you would have started to forget it. Confident reviews push the next date further out; shaky ones bring it closer.

I'm not getting daily reminders.

Check three things:

• iOS Settings → Notifications → LeetReviewer — notifications must be allowed.
• Profile → Notifications in the app — the daily-reminder toggle must be on, and a time must be set.
• You actually have problems scheduled for today. The reminder intentionally stays silent on days with no due reviews.

If all three look right and you still aren't getting them, email us with the time you expected the notification and the time zone on your device.

I signed in with Apple and the app is asking for my email.

When you first sign in with Apple you can choose to share or hide your email. If you hid it (or signed in again later — Apple only sends the email on the first authorization), LeetReviewer uses a placeholder address and shows a banner asking you to add a real email. Adding one is optional but lets us send the weekly digest and account-recovery emails. You can also revoke and re-authorize Apple sign-in from iOS Settings → [Your name] → Sign-In & Security → Sign in with Apple → LeetReviewer to be re-prompted.

I forgot my password.

On the login screen, tap Forgot password?and we'll email you a reset link. The link is good for one hour. If you signed up with Apple, Google, or GitHub, use the same button you used to sign up — there is no separate password in that case.

How do I change the email on my account?

Open Profile → Settings → Email. You'll need to confirm the new address by clicking a link we send to it. The change takes effect once confirmed.

How do I delete my account?

Open Profile → Settings → Delete accountin the mobile app. This permanently removes your problems, notes, review history, and account record. The action is irreversible and takes effect immediately. If you can't access the app, email us from the address on the account and we will process the deletion manually.

Can I export my data?

Yes — open Profile → Settings → Export dataon the web app to download a JSON file with all your problems, notes, and review history. If you only have access to the mobile app, email us and we'll send the export.

The app is crashing or behaving strangely.

Try the following in order:

• Force-quit and relaunch the app.
• Make sure you're on the latest version (App Store → Updates).
• Restart your device.

If the issue persists, email us with: the steps that reproduce it, your iPhone model, your iOS version, and the time it happened (we use that to look up server logs).

Is my data shared with anyone?

No. Your code, notes, and review history are private to your account. We do not sell data, do not use it to train models, and do not share it with third parties beyond the infrastructure providers needed to run the service (hosting, crash reporting, transactional email). Full details in our privacy policy.

Is LeetReviewer affiliated with LeetCode?

No. LeetCode is a registered trademark of LeetCode LLC. LeetReviewer is an independent tool that helps you remember problems you solve on LeetCode (or anywhere else). We link to leetcode.com for problem statements; we don't republish their content.
