Privacy Policy
Last updated October 5, 2026
Information we collect
When you request an account, we collect your first and last name, email address, a password verifier, and—if you provide it—your phone number and SMS preference. We also save whether you opted in to future email alerts. Email verification codes are short-lived. We store names, email addresses, and phone numbers encrypted in the account database; email and phone lookup values are hashed. Passwords are never stored as plain text. The browser derives a salted PBKDF2-SHA-256 verifier before sending signup data.
If you choose to share a calendar report, we store the city, visa category, earliest date, capture time, consent version, and a hashed extension installation identifier. We do not collect portal passwords, passport or application details, page text, or screenshots. Reports are removed after 30 days.
How we use information
Account information supports pilot signup, email verification, and future account access. Email and SMS alert preferences are recorded with their consent time; SMS alerts are not active during this pilot and we do not send SMS messages. Community reports help show recent user-submitted availability. Account access is still in pilot preparation.
Service providers and security
Cloudflare hosts the API and database. Resend processes email delivery when configured. These providers process data to operate the service. We use encrypted transport, database encryption for direct identifiers, and restricted access; no online service can promise absolute security.
Retention and your choices
Reports are retained for up to 30 days. Signup codes expire after 10 minutes and failed or expired pending signups are removed. Verified account details are kept until you request account deletion. You may request deletion or ask a privacy question at alerts@slotsignal.com. Pilot update emails include an unsubscribe option.
Children and changes
SlotSignal is not intended for children under 13. We may update this policy as the pilot develops; the date above shows the latest revision.
