Frequently Asked Questions
How does the ELO system work?
The ELO system calculates fair ratings based on match results. When a lower-rated player beats a higher-rated player, they gain more points. This means rankings reflect true skill, not just how many games you've played.
Does the app support doubles (2v2)?
Yes. You can register 2v2 matches and each team gets its own ELO rating, separate from singles ratings on the same scoreboard.
Can I have multiple scoreboards?
Yes. You can create as many scoreboards as you like for different games or groups. Offline scoreboards are unlimited and stay on your device. Online scoreboards sync across devices and let you invite other people.
How do I invite people to my scoreboard?
Open the scoreboard, tap the share icon, and choose between a QR code or a link. Anyone who scans or opens the link is taken straight to the scoreboard, even if they don't have the app installed yet.
I was added as a guest. Can I claim my profile?
Yes. If an admin added you as a guest player, you can claim that profile by signing up with your email. Your existing matches, wins, and ELO history are kept and tied to your new account.
What languages does the app support?
ELO Rankings is available in 17 languages. The app picks the language from your device settings automatically, and you can change it manually under Settings.
Is my data secure?
Your data is stored securely on Supabase infrastructure inside the EU with row-level security. We never share or sell your data. Offline scoreboards are stored locally on your device only.
How do I delete my account?
Go to your profile in the app and tap Delete Account. This will permanently remove your account and personal data. Match results and ELO history shared with other scoreboard members may be retained so their statistics stay consistent. If you cannot access the app, email contact.nordicworks@gmail.com with the subject "Delete my account" and your registered email.
The app isn't working properly. What should I do?
Try closing and reopening the app, or reinstalling it. If the issue persists, email us at contact.nordicworks@gmail.com with a description of the issue, your device model, and OS version.
