SMS Authentication Policy

We use SMS messaging solely for the purpose of two-factor authentication (2FA).

Information Collection:

We do not collect, store, or use phone numbers submitted for SMS verification beyond the temporary delivery of a one-time passcode (OTP).

In the future, if we need to store or process phone numbers, we will update this policy and explicitly obtain user consent.

User Consent (Opt-in):

By entering your phone number on our website to log in or register, you consent to receive a one-time SMS verification code.

No marketing or promotional messages will be sent.

Opt-out:

These messages are one-time transactional verifications initiated by the user.

Therefore, an opt-out mechanism is not required in this context.
