SinkJar
Tell it the bill and the date — it tells you what to put aside each payday
Unlimited sinking-fund jars for Christmas, registration, insurance, the vet and the brake job. Calendar-aware per-paycheck targets, a deposit ledger, and a saved-vs-target trajectory chart. Free, no install, no bank link.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in SinkJar on the web
Calendar-aware per-paycheck target
“$1,200 by December 1” becomes “$52 every two weeks” — rounded up to the cent so you never land short, and recomputed after every deposit.
Unlimited jars with progress rings
A tile for every lumpy bill with its own emoji, target, date and payday cadence — weekly, every two weeks, or monthly. No ten-envelope cap.
Manual deposits, no bank link
Log what you actually moved in your own bank with quick +$20/$50/$100/$200 taps, a note and a date. No Plaid, no credentials, no consent screens.
Trajectory chart
Your cumulative saving line against the straight line to target, plus an ahead-of-pace or behind-pace figure in dollars for the jar you pick.
Payday plan
Every payday, see which jar needs the biggest slice, the total to set aside, and the next payday date for each jar rolled forward by its cadence.
CSV and JSON export
One file with every jar and every deposit for Numbers or Excel, or a full JSON backup — everything stays in this browser otherwise.

Questions
Is the web version of SinkJar free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the SinkJar iPhone app?+
The iPhone app schedules a local payday notification each pay period; the browser version cannot, so the Paydays tab is the reminder — open it when you get paid. Deposits are always manual here, exactly as on iPhone: SinkJar never links to a bank, so nothing is imported automatically. Jars and deposits live in this browser only. Export the CSV or JSON backup before clearing site data or switching devices.
