RHEO — ῥέω · GREEK: TO FLOW
TIME,
MADE LEGIBLE.
RHEO is a private time tracker for your desktop. It records which apps you use, keeps the record in your own data folder, and lets you ask questions about it.
Your hours are the only currency you can never earn back. RHEO records how they flow — so every phase of your life can be seen, questioned, and improved.
A DAY, REPLAYABLE.

THE WHOLE APP. UNRETOUCHED.

SECTION 03 / UNDERSTAND · EXAMPLE ANSWERS
AN AI THAT WAS THERE.
It doesn't guess about your time. It queries the record — and answers with receipts. Keep asking, and the record teaches back — your process, redrawn as your habits change.
Written examples, not recordings. A real answer uses today’s activity, last night’s sleep, your goals, activity you logged away from the computer, and anything you connect.
SECTION 06 / DOWNLOAD
OWN YOUR HOURS.
Everything else needs your key, your provider, or something you turned on. Ask the AI a question and your day’s summary goes to the provider you picked — choose a local one and nothing leaves.

One database, three files: db, -wal, -shm. The combination is yours.
deskflow-audit-key.bin — the audit key is a file, not a secret in a keystore.
No account. No cloud. No subscription. Close RHEO before copying the folder.
