Everyone loves being remembered. How you take your coffee. Your birthday. Allergies and dietary restrictions. What you need to sleep comfortably. Favorite foods. Pref is the place to record your real world preferences — and share them with the people and businesses who care. It's fun to add your prefs, and you can ask piña the Pref assistant to answer questions about your friends, their dependents (kids, pets, adults), and their relationships. If you have someone's number saved in your phone, and they have yours saved, you're automatically friends. A few moments Pref is built for: -A friend wondering what to bring to your birthday dinner -Remembering your buddy's dog's name -A new babysitter asking what your kid needs to fall asleep -Figuring out what drinks to get for the wedding -Taking out a date for the first time -Hosting an important sales prospect -A memory care nurse meeting your dad for the first time -Planning a dinner party menu (no cilantro!) -Organizing the team offsite for coworkers -A hotel that actually wants to get it right -A petsitter who wants all the details before you head out Plus never forget a birthday again, with customizable birthday reminders for all your friends. Privacy first: phone numbers are hashed before they touch our server, audio and photos stay on your device, and there's nothing to sell. Read the full policy at prefpref.com/privacy. Pref is free. Someday we'll make money when businesses request your prefs, or when we help you choose businesses that respect your prefs.
