About this app

Memkeep is a shared diary for the people you love most.

Some moments are too good to keep to yourself, and too personal to post on social media. Memkeep is a private, end-to-end encrypted memory book you build together with your partner, your closest friends, or your family. No followers. No ads. No algorithm. Just the two (or three, or four) of you.

WHY MEMKEEP IS DIFFERENT

• Truly private. Every photo and word is end-to-end encrypted by default. Not a paid upsell. Not "encryption in transit." Real E2E. We can't read your memories. Nobody can but you and the people you invite.

• One-time purchase, no subscription. Buy a notebook once and it stays yours. No monthly fee, no renewal you forget to cancel, no paywall that grows every year.

• Works offline, syncs later. Built on a local-first architecture, so the app is fully usable on a plane, on a hike, or anywhere with no signal. Your entries sync automatically the moment you reconnect.

• Built for two (or a few). Memkeep is designed for couples and small friend groups. Create a shared notebook, invite your partner or your closest friends, and start writing. Family use is supported too.

• No social media patterns. No likes, no follower counts, no public profiles, no algorithm deciding what you see. Just your shared timeline, in chronological order, the way memories actually happen.

• No ads, no tracking, no data selling. Ever.

PERFECT FOR

• Couples. Capture date nights, trips, anniversaries, and the small daily moments that make a relationship.
• Long-distance partners. Stay close even when you're apart, with a private feed only you two can see.
• Close friend groups. Document trips, inside jokes, and the years you spend together.
• Families. Build a shared memory book across generations, without putting your kids on social media.

PRIVACY YOU CAN VERIFY

Most "private" diary apps store your data in plain text on someone else's server. Memkeep doesn't. Your words and photos are encrypted on your device before they ever leave it. Even we, the developers, can't read them. Your shared diary belongs to you and the people you invited, nobody else.

Your account is protected by a recovery phrase, so you stay in control of your own keys.

LOCAL-FIRST, BY DESIGN

Memkeep is built on a modern local-first architecture. That means instant writes, no spinners, no "trying to reconnect" errors, and a real app that keeps working when your signal doesn't.

START TODAY
