Cash Expense Tracker
Email-tracked spending, with cash in the same place.
Numero tracks purchases from Gmail and Outlook automatically. Add cash and in-person spending by hand so nothing sits in a separate list.
Read-only Gmail access. No bank credentials. Cancel anytime.
Updated
An inbox-based tracker sees everything that leaves an email trail: online orders, subscriptions, bills, refunds. Numero reads those from an authorized Gmail or Outlook account with no bank login and no manual entry required.
Cash doesn't send email. Neither does a market stall, a tip, or a payment to a friend. Instead of keeping those in a separate notebook or spreadsheet, add them to Numero by hand in a few seconds — merchant, amount, date, and category.
Manual entries land in the same Financial Memory as your email activity, so search and category views reflect both instead of only the half that arrived by email.
How it works
Three steps, then Numero does the rest.
STEP 01
Connect Gmail or Outlook
Numero recognizes purchases, bills, subscriptions, and refunds from your inbox automatically, read-only, with no bank credentials.
STEP 02
Add cash spending by hand
In the Numero app, tap Add, enter the amount and merchant, and pick a category. No bank connection and no receipt required.
STEP 03
See it all in one history
Manual and email-recognized activity share one Financial Memory — searchable and categorized together.
What Numero catches
Every moment worth knowing.
Numero surfaces only what deserves your attention right now, with a reason attached.
Subscription renewed
A recurring charge just went through — with the exact amount and what changed since the last cycle.
Refund still pending
A return was accepted but the refund has not landed within the merchant's stated window.
Duplicate charge
The same merchant appears to have charged twice for one purchase.
Unexpected charge
A charge appeared from a merchant with no recent activity from you.
Price quietly went up
A recurring charge increased more than usual — surfaced before it becomes the new normal.
Free trial ending soon
A trial converts to a paid plan in the next few days — flagged before the first real charge.

Guides and connected workflows.
Read-only. Metadata only. Never sold.
Numero uses Google's read-only Gmail scope. Email bodies and attachments are processed ephemerally and never stored. You control export and deletion.
Also useful
Numero does more than one thing.
Your inbox does most of the work. Scan the rest.
Numero finds emailed receipts in Gmail and Outlook automatically. For the paper ones, photograph or upload the receipt in the app and review it before it's saved.
Find paid subscriptions hiding in your email.
Turn receipts, renewal notices, trial messages, and price changes from authorized Gmail and Outlook accounts into connected recurring-cost evidence.
Keep every purchase refund tied to its evidence.
Connect the purchase, return, merchant timing, refund reference, and source messages into one case without confusing initiation with settlement.
Frequently asked
Answers before you sign up.
No. Anything that produces an email — online orders, subscriptions, bills, refunds — is recognized automatically from a connected inbox. Manual entry is only for spending with no email trail, such as cash.
Yes. In the Numero app you can skip connecting an inbox and add expenses manually. Connecting Gmail or Outlook later is what lets Numero find the rest automatically.
Yes. Manual entry is available on the free plan. Photographing or uploading a receipt so Numero drafts the details is included in Pro and Premium.
No. Numero never asks for bank or card credentials. Email-based activity comes from read-only inbox access, and cash comes from what you add.
No. Numero organizes and surfaces your spending evidence; it doesn't ask you to build or maintain a budget, and it isn't accounting or tax software.
