Effective date: June 7, 2026
This privacy policy describes how Serge Braverman (“we,” “our,”
or “us”) collects, uses, and protects information in connection with the
Vox platform and associated services reachable at sergebraverman.com and its subdomains.
Information We Collect
We collect only the information necessary to provide authentication and core service functionality:
- Email address. Collected when you sign in via our primary login method. Used to deliver a one-time magic sign-in link. This is the main way to authenticate across the platform.
- Phone number. Collected only if you use the SMS sign-in option offered on certain apps (currently cartalk). Used solely to deliver a one-time verification code via SMS. This is an additional, optional login method — not required for platform access.
- Session token. A randomly generated token issued after successful verification (by either method above). Stored in your browser and used to authenticate subsequent requests. Expires after 30 days.
- Display name. An optional name you provide when setting up your account. Stored in our database and used to personalize responses.
We do not collect passwords, payment information, or precise location data.
How We Use Email and SMS
Email and SMS messages sent by this service are used exclusively for authentication. Specifically:
- Email (primary method): you submit your email address on the login page; we send a one-time sign-in link to that address; clicking it verifies your identity and starts a session.
- SMS (additional method, cartalk only): you submit your phone number on that app’s login screen; we send a single 6-digit one-time code to that number via SMS.
- No marketing, promotional, or unsolicited messages are ever sent via either channel.
- Message frequency is one message per login attempt. You will not receive messages unless you actively request one.
- Standard message and data rates from your carrier may apply to SMS.
To stop receiving SMS messages, simply do not use the SMS login option. You can also
contact us at [email protected]
to have your phone number or email address removed from our system entirely.
How We Share Information
We do not sell, rent, or share your personal information with third parties for marketing
or advertising purposes. The only third-party disclosures are:
-
Resend. Our email delivery provider. Your email address is transmitted
to Resend solely to deliver the magic sign-in link. Resend’s privacy policy
governs their handling of that data.
-
SignalWire. Our SMS delivery provider. Your phone number is transmitted
to SignalWire solely to deliver the verification code, if you use the SMS login option.
SignalWire’s privacy policy governs their handling of that data.
We may disclose information if required by law or to protect the rights and safety of
our users, but we have no current practice of doing so.
Data Retention
Phone numbers and session tokens are retained as long as your account is active.
Expired session tokens are purged periodically. If you request account deletion,
all associated data is removed within 30 days.
Security
Session tokens are randomly generated and stored only in your browser. Verification
codes expire within 10 minutes and are invalidated after use. We enforce rate limits
on verification attempts to prevent abuse.
Children’s Privacy
This service is not directed to children under 13. We do not knowingly collect
information from children under 13.
Changes to This Policy
We may update this policy as the service evolves. Material changes will be noted
with a revised effective date. Continued use of the service after changes constitutes
acceptance of the updated policy.
