Custom User is a way to view submissions of a friend. Note: Only you can see his/her submissions

You can explicitly update the submissions by clicking on the "Retrieve my submissions" button on profile page. Also, the submissions are automatically updated every morning with a few optimizations - exact process

Best option is to ask him/her register on StopStalk and then add him/her as your friend. If not, then you can add a Custom User if you already know all the handles.

At present, the limit is set to 3 per user. We are working on it so that this limit is increased

StopStalk rating is determined by a very unique formula which takes care of number of solved problems, maximum streak, accuracy, per day changes and effort

Whenever user joins StopStalk, per day change is 0.0 and number of problems solved per day are computed. After every day this get modified depending on number of solutions submitted. Positive value says that you have benefitted after joining StopStalk

The sites that which allow to view anybody's submissions publicly have a View button. At present Codechef, Codeforces (non-gym problems) and HackerEarth submissions can be viewed and downloaded.

Yes, the code is completely open-sourced and it is on Github

All you have to do is ask your friend to enter your StopStalk handle when asked for Referrer's StopStalk handle.

Yes. You can increase the limit of number of custom users per user. At present 3 custom users are allowed on successful registration. On referring of 3 friends with your StopStalk handle you get 1 extra custom user.

All the time stamps are shown in your local timezone (Browser Timezone)

We have limited number of Institutes at present. Just fill "Other" in the Institute field and just write an email to us ([email protected] or [email protected]) stating your institute name and we will update your institute.

At present no, but we will keep your data in our database and try to send it as soon as possible

This is because we need to retrieve the submissions from the new handle (Just in case you have added or updated to a valid handle). This will also result in re-computing your StopStalk rating from scratch as we don't want to show fake increases in the ratings.

HackerRank does not provide submissions of a user publicly. It only exposes a page that shows the solved problems, and hence there are only accepted submissions.

We have changed the retrieval process now. Please remove Spoj handle from your profile once and then again add it to get all the submissions from Spoj

No. Submissions older than 2013-01-01 00:00:00 IST are not retrieved on StopStalk.

We mark invalid handles after the StopStalk registration. These invalid handles are re-evaluated weekly to check if the user has registered on the profile site with the same handle and should be marked valid on StopStalk as well.

We blacklist accounts which seem suspicious in terms of StopStalk product usage or providing invalid handles. These can be re-enabled only on analyzing the genuine use-cases via Support.

Streak is computed by solving/attempting a new problem every day. If there is only an accepted submission on an already solved problem then that day is not counted in streak computation.

If the submissions are made to a private contest and are not available on the profile page publicly, StopStalk cannot fetch them and are hence skipped.
