## What is Abox Mark · Time Capsule?

Abox Mark is a minimal mood journal for private, on-device moments.

Leave a line, a mood, and an optional place in seconds. Hold to seal — sealed entries can’t be edited. No account, no cloud, no social feed. Remember without writing a long diary. Leave something without performing for an audience.

Time remembers you. So your future self can meet who you are now.

[Leave this moment in seconds]
Open compose. Optionally add a place, pick a mood, or write one line.

Mood or text is enough to seal. Place is always optional — type it, or fill in your current place name.

200 characters max. Enough to mark the moment. Not enough to become homework.

[Seven states of life]
Calm, Happy, Inspired, Tired, Down, Missing, Looking forward.

Not a psychology quiz — just familiar human weather. Pick one, or skip mood and leave only words.

[Hold to seal this moment]
Not a safeguard against taps. A small ritual.

Press and hold the fingerprint button for about a second and a half. The ring closes. The moment is fixed. Sealed marks can’t be edited — what’s saved is what was real.

[A timeline that collects time]
Open the app and meet who you once were.

Browse newest first. Scrub the month marks on the side to jump through time. New seals land gently on the timeline — like a stamp settling into place.

[A glance at your time]
In Settings, see how many marks you’ve left and how far your span of time reaches.

A quiet summary — not streaks, not dashboards, not pressure to keep a chain alive.

[Private, on your device]
• No account, no sign-in
• No cloud sync, no social
• Marks stay on this device only

No sharing. No likes. No comments. A mood journal and time capsule for you alone.

Abox Mark is not trying to help you record more.

It focuses on one path — leave → seal → meet again later — and keeps it quiet and true.
