FAQ
What if I want a refund?
Email heavyweightsanonymous@gmail.com within 24 hours of buying and we'll refund the full $5. No questions, no forms.
Are the PINs safe?
PINs are hashed (PBKDF2) before they touch our database — even we can't read them. The plaintext version is shown to you exactly once, on the success page and in the welcome email. Save the email.
What happens at the end of the competition?
The page keeps working forever — you can still see the final leaderboard and chart whenever you want. Nothing expires.
Is my data shared with anyone?
No. We collect the absolute minimum (your email for the welcome message, the names & weigh-ins of competitors). We don't run analytics, ads, or any kind of tracking. See our privacy policy for details.
Can anyone with the URL log fake weigh-ins?
No — every weigh-in requires the PIN of the person logging it. Without the PIN, anyone with the URL can only view, not edit.
