Overview
At Win5, we respect your privacy and are committed to protecting your personal information. This policy explains what data we collect, how we use it, and how long we keep it.
Key Point: This is NOT a user account system. Each day you submit a new entry to the giveaway. We do not create persistent user profiles.
What We Collect
When you enter the daily giveaway, we collect:
- Email address - To notify you if you win
- Solana wallet address (optional) - To send your prize if you win
- Device information - IP address, browser type, operating system, timezone (for anti-fraud purposes)
- Country - Detected from your IP address
- Referral data - If you joined via a referral link
How We Use Your Data
- Process your daily giveaway entry
- Randomly select winners
- Send winner notifications
- Transfer prizes to winners
- Prevent fraud and abuse
- Display public winner records (anonymized)
- Publish blockchain proofs for transparency
How Long We Keep Your Data
If You Don't Win:
Your email and personal information are automatically deleted immediately after the daily draw completes (00:00 UTC).
We keep only anonymized hashes for fraud prevention. No one can identify you from these hashes.
If You Win (With Wallet Provided):
- We send you an email notification
- We transfer $5 USDT to your wallet
- We publish blockchain proof
- Your email is automatically deleted within 10 minutes after the proof is published
If You Win (Without Wallet):
- We send you an email with a claim link
- Your email is kept until you submit your wallet address
- Once you claim: we send the payment, publish the proof
- Your email is automatically deleted within 10 minutes after the proof is published
Claim deadline: You have 7 days to claim your $5.
What Remains Public
After your personal data is deleted, we keep public winner records showing:
- Date of win
- Prize amount ($5)
- Masked wallet address (e.g., "XXXX...XXXX")
- Country flag
- Blockchain transaction link
This ensures transparency - anyone can verify we paid winners as promised.
Blockchain Transparency
Every draw is verifiable on the Solana blockchain. We publish three proofs:
- Commitment proof - Published before selecting the winner
- Winner proof - Published after random selection
- Payout proof - The actual $5 USDT transfer transaction
These proofs are permanent and public. Anyone can verify we didn't cheat.
