How can we help?

Log in to your bank's internet banking, navigate to your account transaction history, and download your transactions as a CSV file. See the guides below for exact steps for each bank.

Open Comma and go to the Settings tab. Drag your CSV file onto the upload area, or click to browse. Comma will automatically detect your bank format and show a preview of your transactions before importing.

Check the transaction preview — you'll see how many transactions were detected, the date range, and a sample of the auto-categorisation. Confirm to import, and your dashboard will update instantly.

Repeat for each bank account, credit card, or investment account you want to track. You can import CSVs from multiple banks — Comma keeps them separate and combines them in the overview.

It means your data is encrypted in your browser — on your device — before it's sent anywhere. Comma's servers receive an encrypted blob. We have no way to read it. Even our own team cannot access your financial data.

Your data cannot be recovered. Your password is the encryption key — without it, the encrypted data is permanently inaccessible to you and to us. This is what makes the privacy guarantee real: if we could recover your data, it would mean we could also read it.

We strongly recommend storing your Comma password in a password manager like Bitwarden (free) or 1Password.

Yes — go to Settings → Account → Change password. When you change your password, Comma re-encrypts your data with the new key. Make sure you remember the new password before confirming.

Yes. The Free tier requires no account and stores everything in your browser's local storage. Your data never leaves your device. If you clear your browser data, your Comma data will also be cleared — so the Free tier isn't suitable as a long-term backup. Upgrade to Pro for encrypted cloud sync.

Use the manual column mapping screen that appears automatically. Select which column in your CSV corresponds to Date, Description, and Amount (or Debit/Credit if your bank uses separate columns). Comma will save the mapping for next time.

Comma uses 150+ Australian merchant patterns to auto-categorise, but it won't catch everything. You can manually reassign categories on any transaction — tap the transaction and select the correct category from the list. If a merchant is consistently miscategorised, let us know and we'll add it to the pattern list.

This usually happens when the date ranges of two CSV exports overlap. Comma detects exact duplicates and skips them on import — but if the transaction descriptions or amounts differ slightly between exports, it may create duplicates. Use the Search tab to find and remove duplicates manually, or re-import with non-overlapping date ranges.

Some banks export debits as positive numbers instead of negative. In the manual column mapping screen, use the Invert amounts toggle to flip the sign of all imported transactions. If you've already imported, get in touch and we'll help you fix it.

Some banks export files with a .csv extension that are actually formatted differently (tab-separated, or with unusual encoding). Try opening the file in a text editor — if the values are separated by tabs or semicolons instead of commas, you'll need to convert it first. Open it in Excel or Google Sheets and re-save as CSV (comma-separated).

After purchase, you'll receive a confirmation email from Lemon Squeezy with your licence key. In Comma, go to Settings → Account → Activate licence and enter the key. Your account will upgrade immediately.

We offer a 30-day no-questions-asked refund. Email hello@getcomma.com.au within 30 days of purchase and we'll process it promptly.

Go to Settings → Account → Delete account. This will permanently delete your account and all encrypted data from our servers within 30 days. This action cannot be undone.

Yes, with a Pro or Lifetime licence. Your encrypted data syncs across devices automatically — just log in with the same account and password. Free tier data is stored locally in each browser and doesn't sync.
