Your private intimacy journal. On your device. Yours alone. Hook is a private journal for your relationships and intimate life. Reflect on the moments that matter and see your story unfold over time. Everything stays on your device, locked behind Face ID. No accounts, no cloud, no sharing. Hook is a personal journal — not a dating service or social network. It's built for adults who want a private space for personal reflection: couples keeping a shared journal, individuals reflecting on their relationships, anyone who values a truly private place for their own story. PRIVACY FIRST Your entries live on your device. No accounts, no servers, no sync unless you turn it on. Face ID or passcode locks the app from launch. iCloud Backup is optional, off by default. Private health reminders on your own cadence. WHAT YOU CAPTURE The moments that matter — when, where, and how you felt. Notes, moods, and tags you build yourself. Personal entries, or shared entries with a partner. WHO'S IN YOUR STORY Every partner gets a profile: a color, emoji, or photo avatar, plus the details you choose to remember — birthdays, preferences, and cycle tracking. WHAT YOU SEE A heatmap of your year. Patterns over time. Mood and location breakdowns. A clear view of your own story. YOUR STORY, MAPPED Pin meaningful moments to a map and revisit the places that have been part of your story. HOOK+ Unlimited profiles. Full stats. Map view. No ads. BUILT FOR Adults of every gender, orientation, and relationship structure. If you want a private place to capture and reflect on your own story, this is for you. Available in 12 languages, including English, French, Spanish, German, Italian, Polish, Portuguese, Japanese, Korean, and Chinese. Your story, clearly. Yours alone.
