Security & Privacy

We care about the safety and privacy of your data. Our system is designed with built-in security to protect your personal information at every step.

Data Encryption

We use encryption to keep your sensitive information safe :

Passwords are encrypted using bcrypt and cannot be read or recovered in their original form.

All communication between your browser and our server is secured using HTTPS.

Other data like event names, participant names, positions, and emails are stored using unique IDs, so each event and participant has their own secure reference.

How We Handle Personal Data

Here’s how we handle and protect your data :

We store only the data needed for the system to function: your account info (encrypted email & password), event data, and participant data (name, email, and position).

Only developers can access this data, and they do not have access to decrypted passwords.

We do not share or sell your data to any third party.

We collect your public IP address during email verification to help confirm that it's you using the same device.

Our system has an automatic backup feature to prevent data loss.

When you delete your data, it is soft-deleted first and then permanently deleted after some time.

User Control Over Data

You have control over your own data :

You can edit event and participant details at any time.

You can delete individual or all participants within an event.

You can request to delete your account or personal data at any time.

At the moment, you cannot download a full copy of your data.

Only event owners can access the data they created; others cannot view it.

Troubleshooting Guide

Everyday issues you might face and how to resolve them.
This guide covers the most common problems that users may encounter while using the website and how to fix them easily.

File Upload Fails

Problem: The Excel (.xlsx) file upload doesn't work.
Solution:

Make sure the file is less than 10MB.

Ensure the file has the required columns: name, email, and position in the first row.

If the upload still fails, re-upload the file. A toast notification will show whether the upload was successful or failed.

Participants Limit Reached

Problem: You can't add more participants to an event.
Solution:

Each user has a participant limit. Make sure your current total doesn't exceed your plan's limit.

A toast notification will inform you when the limit has been reached.

QR Code Doesn't Show

Problem: The QR code is not visible inside the table row.
Solution:

QR codes are loaded per row. If you see a blank space, it’s likely still loading.

Wait a few seconds or scroll to trigger lazy loading.

This is not an error—QR data exists but is still rendering.

Toast Says Action Failed

Problem: After performing an action (update, import, delete), the toast shows a failure.
Solution:

Read the detailed error message inside the toast.

Most failures are due to expired sessions, file errors, or invalid form data.

If your session expired, you'll be asked to re-login for security.

Session Expired

Problem: You're logged in but actions suddenly fail.
Solution:

Session tokens expire after 3 days of inactivity.

Re-login to continue using protected features.

Form Won’t Submit

Problem: You can't update or submit a form.
Solution:

Check all required fields—name, email, and position must be filled correctly.

Real-time form validation will show messages below each field.

No toast will appear until the form is sent to the server.

Can't Download QR Code

Problem: QR Code download doesn’t work or opens wrong format.
Solution:

Choose a valid format: .webp (default), .jpeg, .jpg, or .png.

Ensure that you have selected a participant before clicking download.

Use the dialog box to confirm and press Download.

Can't Download All QR Codes

Problem: Bulk QR Code zip file won't download.
Solution:

Make sure participants exist in the event.

This button only appears below the table when there's at least one participant.

Error While Editing Participant

Problem: Nothing happens when updating a participant.
Solution:

Click the Update button on the correct row.

Make sure all three fields are filled.

Press Save Changes inside the sheet and wait for toast confirmation.

Unable to Delete Participant

Problem: You tried to delete a participant but nothing changes.
Solution:

Check the confirmation popup—you must confirm before deletion.

Toast will confirm deletion. If it fails, the system will cancel the process.

Table Feels Slow

Problem: The participant table is slow to load.
Solution:

Each page is limited to 10 participants with pagination.

QR codes are loaded with each row, which may cause a short delay.

Wait for the loading indicator to complete.
