Opinion

BIANCA SLAVIERO, et al., Case No. 25-cv-09496-RS Plaintiffs, v. ORDER GRANTING MOTION TO BABY LIST, INC., Defendant.

Two plaintiffs—Bianca Slaviero and Aisley Davis—sued Baby List for various privacy- related torts. Baby List moves to compel arbitration and dismiss the case. Because Plaintiffs assented to an enforceable arbitration clause that delegates the issue of arbitrability, the motion is granted. Baby List is an online platform that helps parents-to-be create and manage gift registries. Davis and Slaviero registered for Baby List accounts in 2024 and 2025, respectively. To create their accounts, Plaintiffs first had to fill out a questionnaire that asked, among other things, when the baby is due and whether the user has other children. After completing the questionnaire, Plaintiffs were directed to the sign-up page. It asks for the user’s name, email address, and password. Below those information fields is a purple button labelled “Sign Up.” Below that, in slightly smaller grey font, is a line of text that reads “By clicking Sign Up you agree to the ] Babylist Terms of Use and Privacy Policy.” That webpage is shown below. 2 @ babylist 3 4 Start your registry and we'll support you along the way! 5 Continue With Google 6 Or 7 8 Email address 9 Password nies @

98 ORDER GRANTING MOTION TO COMPEL ARBITRATION CASE No. 25-cv-09496-RS

On both pages, the terms “Babylist Terms of Use” and “Privacy Policy” were displayed in black ink and were underlined. Those terms contained hyperlinks to the terms of use and privacy policy, respectively. At the time Davis signed up, the 2023 terms of use were operative. At the time Slaviero signed up, the 2025 terms of use were operative. Both versions contain the same mandatory individual arbitration provision. Specifically, the terms of use provide: In the event a dispute arises between You and Babylist, please contact Babylist. Any dispute arising from or relating to the subject matter of these Terms shall be finally settled by arbitration in San Francisco, California, using the English language in accordance with the Arbitration Rules and Procedures of Judicial Arbitration and Mediation Services, Inc. (“JAMS”) then in effect . . . Levada Decl., Ex. A, at 17 (2023 terms); see id., Ex. B, at 26 (substantially similar provision in the 2025 terms). Both terms of use permitted Plaintiffs to opt out of the arbitration requirement. The relevant provision provided: RIGHT TO OPT OUT OF ARBITRATION WAIVER. You may opt out of the foregoing Arbitration Agreement of these Terms by notifying Babylist in writing within 30 days of the date You first registered for the Services or 30 days from the date these Terms were last updated. To opt out, You must send a written notification to Babylist at Baby List, Inc., 1900 Powell St, Suite 150, Emeryville, CA 94608, Attention: Legal, that includes (i) Your name, account username, address, telephone number and email address, and (ii) a clear statement indicating that You do not wish to resolve claims through arbitration and demonstrating compliance with the 30-day time limit to opt out of the above arbitration provision. Id., Ex. A, at 17 (emphasis in original); see id., Ex. B, at 27 (2025 terms). Neither plaintiff opted out of the binding arbitration provision. Plaintiffs sued Baby List, asserting one cause of action under the Federal Wiretap Act, 18 U.S.C. § 2510, et seq., and two causes of action under California law. They aver that Baby List helped various third parties collect the responses that Plaintiffs provided to Baby List in the initial onboarding survey. Baby List moves to compel arbitration. Under the Federal Arbitration Act, contractual arbitration agreements “shall be valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C. § 2. “By its terms, the [FAA] leaves no place for the exercise of discretion by a district court, but instead mandates that district courts shall direct the parties to proceed to arbitration on issues as to which an arbitration agreement has been signed.” See Dean Witter Reynolds, Inc. v. Byrd, 470 U.S. 213, 218 (1985) (emphasis in original). “The [district] court’s role under the [FAA] is therefore limited to determining (1) whether the agreement to arbitrate exists and, if it does, (2) whether the agreement encompasses the dispute at issue.” See Chiron Corp. v. Ortho Diagnostic Sys., Inc., 207 F.3d 1126, 1130 (9th Cir. 2000). Plaintiffs make three arguments to avoid arbitration: (1) that they never assented to the arbitration provision, (2) that, even if they did, the provisions are procedurally and substantively unconscionable, and (3) that, in any event, their claims fall outside the scope of the provision. A. Assent to the Arbitration Provision The first question is whether Plaintiffs actually assented to the arbitration provision by clicking “Sign Up” on the Baby List website. To answer that question, federal courts apply state- law principles of contract formation. Chabolla v. ClassPass Inc., 129 F.4th 1147, 1154 (9th Cir. 2025). Here, the parties agree that California contract law controls. “To form a contract under California . . . law, there must be actual or constructive notice of the agreement and the parties must manifest mutual assent.” Chabolla, 129 F.4th at 1154 (quoting Oberstein v. Live Nation Ent., Inc., 60 F.4th 505, 513 (9th Cir. 2023)). Courts’ propensity to find that a party had notice of an agreement formed online depends, in part, on the kind of agreement at issue. The easiest agreement to enforce is a so-called “clickwrap” agreement, in which “a website presents users with specified contractual terms on a pop-up screen and users must check a box explicitly stating ‘I agree’ in order to proceed.” Berman v. Freedom Fin. Network, LLC, 30 F.4th 849, 856 (9th Cir. 2022). “At the other end of the spectrum are so-called ‘browsewrap’ agreements, in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website.” Id. The agreements here resemble a “sign-in wrap” agreement, which falls somewhere in between a (presumptively enforceable) clickwrap agreement and a (presumptively unenforceable) browsewrap agreement. In a sign-in wrap agreement, “the website provides a link to terms of use and indicates that some action may bind the user but does not require that the user actually review those terms.” Chabolla, 129 F.4th at 1154. “Under California law, a sign-in wrap agreement may be an enforceable contract based on inquiry notice if (1) the website provides reasonably conspicuous notice of the terms to which the consumer will be bound; and (2) the consumer takes some action, such as clicking a button or checking
