We believe your peace of mind is the ultimate priority. SelfExclude.io was developed as a voluntary program designed to help you hit "pause" on prediction markets whenever you feel the need. Whether you need a short break or a longer pause, it's about giving yourself the space to breathe and reflect while protecting what matters to you most.
Everything you need to know about our self-exclusion program.
About the Program
SELFEXCLUDE.io is a voluntary program that allows you to exclude yourself from participating prediction markets. Take a step back, regain control, and protect your financial wellbeing.
After you complete identity verification, your information is cryptographically hashed and stored securely. Partner platforms can then query our system to check new and existing users against the exclusion list—without ever accessing your actual personal details. Matches trigger automatic account restrictions.
Currently, Polymarket, Robinhood, and ProphetX are integrated partners. New partners are added regularly.
You can choose any duration from 1 month up to 24 months (2 years), in monthly increments.
Yes. Your personal information is cryptographically hashed before it ever leaves your device. Platforms only receive anonymized data for matching purposes—they never see your actual PII. This triple-blind architecture ensures your identity remains protected at every step.
No. Your data undergoes a double-hashing process before transmission. Platforms query our system using the same hashing method to check for matches—they never receive or store your actual name, address, or ID details. Only a cryptographic match confirmation is exchanged.
Currently, SelfExclude.io is only available to users in the United States. We are focused on US-based prediction market platforms at this time.
Enrollment
Click 'Start Self-Exclusion' on the home page, complete identity verification, and select your duration.
Legal name, address, date of birth, and a government-issued ID for verification.
We use Veriff, a trusted identity verification provider, to confirm your identity during enrollment. This ensures that only you can enroll yourself in the program—no one else can sign you up without your knowledge or consent.
Most platforms activate the block within 24 hours of successful verification.
Platforms handle this differently; generally, you may be allowed to close positions but not open new ones. Contact support for specific platform policies.
Data & Security
Self-exclusion terms range from 1 to 24 months. Once enrolled, your exclusion is binding for the selected period and cannot be shortened. You can extend your term at any time.
Your data is protected using HMAC-SHA512 cryptographic hashing with multiple encryption keys, SSL/TLS 1.3 for all transmissions, and secure cloud infrastructure with strict access controls. Keys are rotated regularly, and your raw PII is never stored on our servers—only irreversible hashes that cannot be decoded back to your original information.
Enforcement typically propagates across the network within 24 hours of a verified submission.
