California Code, Civil Code - CIV § 1694.1

(a) In addition to any other right to revoke an offer, the buyer has the right to cancel a dating service contract or offer, until midnight of the third business day after the day on which the buyer signs an agreement or offer to purchase those services.

(c) Notice of cancellation, if given by mail, is effective when deposited in the mail properly addressed with postage prepaid.

(d) Notice of cancellation given by the buyer need not take the particular form as provided in the contract or offer to purchase and, however expressed, is effective if it indicates the intention of the buyer not to be bound by the dating service contract.

(e) All moneys paid pursuant to any contract for dating services shall be refunded within 10 days of receipt of the notice of cancellation.

(f) The buyer may notify the dating service of his or her intent to cancel the contract within the three-day period specified in this section and stop the processing of a credit card voucher or check by telephone notification to the dating service. However, this does not negate the obligation of the buyer to cancel the contract by mail, email or other electronic means, telegram, or delivery as required pursuant to this section.
