## What is tagTodo?

tagTodo is a privacy-first task manager built on one idea: **everything is a tag.**

There are no lists, folders, or projects to file things into. A task is just a
title and a few tags — #work, #urgent, #waiting, #p1, @home, or a person's name.
A task can belong to many contexts at once, so you never have to choose the "one
right place" for it.

You organize by **querying** the set of tasks with a tiny but powerful
set-algebra language:

• #today & #open — what's due today and not done
• #work & #open & ~#waiting — open work you're not blocked on
• (#work | #personal) & #week — this week, across contexts
• #p1 & #overdue — high-priority tasks past due
• #done & #week — a weekly review of what you finished

Operators are simple: & (and), | (or), \ (except), ~ (not), and parentheses.
Two tags side by side also mean "and". Save any query as a smart list and see
its live count update as you work.

AUTOMATIC TAGS
Some tags are added for you and usable in any query — no typing required:
#open, #done, #overdue, #today, #tomorrow, #week, #nodate, #all, plus time tags
from each task's date (#2026, #JUN, #Q2, #FRIDAY, #WEEKEND, #SUMMER…).

SEE THE STRUCTURE OF YOUR WORK
Every query result comes with a summary (total / open / done / completion % /
overdue), an area-proportional Venn diagram of its most common tags, and charts
for throughput, created-vs-completed, and your open backlog over time.

PRIVATE BY DESIGN
All data stays on your device. No account, no ads, no tracking. Export and
import your tasks any time as JSON or CSV.

BILINGUAL
Fully available in English and Vietnamese.

tagTodo Pro (optional) unlocks unlimited tags per query. A 7-day free trial is
included; monthly, yearly, and lifetime options are available.
