Lock In · Last updated: July 22, 2026
Lock In ("we," "us," or "the app") helps friend groups make plans and actually follow through on them. This policy explains what information we collect, how we use it, and the choices you have. The short version: we collect only what the app needs to work, we don't run ads, and we never sell your personal information.Information We CollectAccount information. When you sign up we collect your name, email address, and optionally your phone number, profile photo, and a short bio. We sign you in with one-time codes sent to your email — there are no passwords, and we don't use third-party social logins.Plans and activity. The plans you create and respond to, including titles, dates, venues, notes, invitations, your commit/decline responses, ratings of past plans, and your commitment score (which is calculated from your response and attendance history).Photos. Profile photos you upload and photos you add to plans, if you choose to share them.Contacts. If you grant contacts access, we use it to help you invite friends. When you select someone to invite, their name and email address or phone number are sent to our servers to deliver the invitation. We do not upload your full address book.Location. If you grant location access, we use your device's location while you're using the app to suggest nearby venues and events. We don't collect your location in the background.Device and technical information. A push notification token (so we can send you notifications you've opted into), the date you consented to SMS messages, and basic logs needed to keep the service running securely.How We Use Your InformationWe use your information to run the app: creating and managing plans, delivering invitations by email or SMS, signing you in with one-time email codes, sending push notifications you've enabled, calculating commitment scores, suggesting venues and events near you, preventing abuse, and fixing bugs.
