Where it lives

Open a browser, that is all

  • It lives on the web, with nothing to install
  • Use it on any device, from any browser - your data moves with you
  • Add it to your home screen and it loads like a mobile app

End-to-end encrypted

Locked with a key only you have

In your journal

Coffee on the porch before anyone else was up, and the first frost on the garden beds.

On our server

  • Your words, names, photos, and locations are sealed with a key made from a passphrase you create, which is never sent anywhere
  • Sign in from anywhere and your passphrase opens your record - the passphrase itself is stored nowhere
  • There is no locksmith: no one can unlock your data but you
  • No AI, no models - nothing is reading what you wrote, this is a space for only you

About end-to-end encryption

Your passphrase never leaves

It is not sent anywhere, and it is not stored anywhere, not on the server, not in the browser. What it does is derive a key: run through PBKDF2-SHA256, 600,000 iterations, with a salt belonging to your account alone, producing a 256-bit key. That derivation happens on the device every time you unlock.

A wrong passphrase is caught here

Your account keeps a canary: a small piece of ciphertext only the right key can open. Unlocking opens it on the device. So the check needs no password on the server to compare against; there is nothing there to steal, and the passphrase is never transmitted to be verified.

What is sealed

Entry titles and notes, journals, photos, tag and task names, location and any amounts. Each is encrypted with AES-256-GCM on the device before it is sent, so what crosses the network and what sits in the database is ciphertext the server has no key for.

What is not

No sensitive or private text ever crosses the network unencrypted. What does travel in the clear is the shape of the record: dates, times and durations, which focus an hour belongs to, colors and order. Shape, never the words you wrote in an entry. It is deliberate: assembling a day from it is what lets the app work without any server ever holding a key.

One exception exists and it is yours to make. Sharing an entry sends the separate public text you wrote for it, never your own title or journal, and any photos on it, which go out as pictures anyone with the link can see.

Where the key lives

Your browser holds it, in a way that nothing can read back, not the app, and not someone poking around inside the browser. The app can ask the browser to unlock your writing while you are signed in, but it never sees the key itself. There is nothing to copy, and nothing to send anywhere.

It is never uploaded. Lock or Sign Out destroys it, and the next visit builds it again from the passphrase you type.

What no one can do

Reset it, recover it, or read around it: not the operator, not support, not us, and not anyone who obtained the database. There is no second key and no override. That is the same property that makes a forgotten passphrase final: the writing stays unreadable.

And we will never ask you for it, not by email, not in support, and nowhere in the app but the screen that unlocks it. Anything that asks you for your passphrase somewhere else is not us.

About Time Mosaic

Time Mosaic is a documentary tracker, a journal of your life as it unfolds. This is a space for you to record thoughts, store photos and memories of your time spent. This app encourages you to slow down and pause, stay present with the moment at hand, reflect on the time gone by and prepare for the time ahead.

What is documentary tracking?

Tracking that focuses on documenting activities and moments instead of changing them, intended for long-term self-expression, reflection and remembering, rather than simply to monitor, regulate and motivate a data-driven life. After Epstein et al., UbiComp 2015 · Elsden, Designing Documentary Informatics, DIS 2017

It is made for documenting a life, not for squeezing more out of the day, so you won't find calendar syncing or AI assistants. Optional Add-Ons can help with tasks and reminders, organize notes and files, track your reading and clip an excerpt, or keep a commonplace of links and quotes - all the little extras that accompany your time and space. But its purpose is to help you pay attention to the time you spend on what matters, and to record what that time means to you.
