What Notchbox is for

Notchbox is a private journal of your trysts, flings, hookups and regular partners. Keep track of who you were with, where and when, what it cost and how it went. Add an entry in seconds, rate it, tag it, and find it again years later.

Over time it becomes your own little black book, with the numbers worked out for you. Monthly totals, favorite venues, trips compared side by side and every place on a map. It's made for people who travel, who meet a lot of people, or who simply want to remember the nights worth remembering, and who would rather nobody else could ever read it.

There's no feed, no profile and no matching. It isn't a dating app, and nobody else is on it with you. Everything is encrypted on your device before it's saved, so it stays yours alone.

How the lock works

1 · Your password

It never leaves your device. It unlocks your own key, inside your browser.

2 · Encrypted on your device

Every entry is sealed with that key before anything is sent.

3 · We keep locked boxes

Our server stores what it can't open. No key, no reset, no way in.

Stats & charts

Monthly breakdowns, spending, trends and a year in review, all worked out on your device from your own entries. Nothing is sent anywhere to be counted.

  • Trips, compared side by side
