CapBudget is a budgeting app that I develop and maintain on my own, in my spare time alongside my day job. It is a local-first project: your data stays on your device.

No account, no ads, and no tracking.

If you find the app useful, the occasional coffee helps keep me motivated to keep releasing improvements. Buy me a coffee, and thank you for your support, whatever form it takes.

CapBudget is a local-first budgeting app. The short version: nothing leaves your device, and we collect nothing.

What data the app handles

Everything you put into CapBudget (bank transactions, account references, categories, categorization rules, budget targets, and app settings) is stored only in a single SQLite database on your device (household.sqlite), in the app's own private storage. There is no account, no login, and no CapBudget server.

What we collect

Nothing. No analytics or usage tracking, no advertising or advertising identifiers, no crash or diagnostics reporting, no third-party SDKs that phone home, no network calls to any CapBudget-operated service (there is none). The app functions fully offline.

CSV imports

When you import a bank CSV export, the file is parsed on your device. It is not uploaded anywhere and is not retained by the app unless you choose “keep” during import.

Backups

You can export a backup from Settings. The backup is a file you control. CapBudget does not upload it and has no access to wherever you save it.

Permissions

The app requests no location, contacts, camera, microphone, or other sensitive permissions, only its own private storage.

Optional tips

CapBudget is free. If you wish, you can leave the developer an optional tip; a tip never unlocks anything. On iOS this uses Apple’s in-app purchase: the payment is processed entirely by Apple, and CapBudget never sees your payment details, your Apple ID or your purchase history, and receives no personal information. On Android and in a web browser a button opens an external donation page in your browser; that page is operated by a third party (Buy Me a Coffee) under its own privacy policy, and nothing from the app is sent to it.

Bank-account references

An account number/IBAN from your CSV is stored to group transactions by account, kept only on your device. In the UI only the last 4 characters are shown.

Contact form on this website

If you write to us through this site, we use your message and the email address you optionally give only to reply. Bot protection is provided by Cloudflare and email delivery by Resend.

Language choice on this website

When you choose a language, or when this site opens a page in your browser's language, it stores one small functional cookie (pxl, a language code, one year) so that your choice is remembered. If this site suggests a page in your browser's language and you close that suggestion, your browser also keeps a local note (pxl-banner-off, in local storage, 30 days) so the suggestion does not come back. Neither identifies anyone, neither is used for tracking or advertising, and neither is shared. You can delete them in your browser at any time.

Website statistics

This website uses Cloudflare Web Analytics to count visits (pages viewed, country, browser type, loading speed). It sets no cookie, does not use local storage, does not fingerprint your device, does not follow you across sites and does not build a profile of you. Search engines (for example Google Search Console) give us aggregated search statistics, without any data about individual visitors. We use no advertising or other analytics service. None of this concerns the app itself, which collects nothing.

Children

CapBudget is a general-purpose finance tool and is not directed at children.

CapBudget is a small independent app that keeps your budget on your device only: no account, no sign-up, no server. Answers to the most common questions are below.

Where is my data stored?

Only on your device, in the app's own private storage. There is no CapBudget account and no CapBudget server, so nobody, including us, can see or recover your data. Details in the privacy policy.

How do I back up my data or move to a new phone?

1. Open Settings → Backup & restore → Download a backup. You get a .sqlite file: keep it wherever you like (Files, a cloud drive, your computer).
2. On the new device, install CapBudget, open Settings → Backup & restore, choose the file and tap Restore from a backup.

A restore replaces everything currently in the app.

I deleted the app or lost my phone: can my data be recovered?

Not unless you exported a backup: the data lives only on the device. Download a backup regularly.

How do I import my bank's transactions?

Export a CSV file from your bank's website, then open the Import CSV tab, choose the file, map its columns once, check the preview (duplicates and invalid dates are flagged) and confirm. Nothing is imported until you confirm.

Can transactions be categorized automatically?

Yes. In Reference data → Rules, create rules such as "label contains RENT → Housing / Rent". You can re-apply them to past transactions at any time; transactions you edited by hand are protected unless you explicitly choose to overwrite them.

How do I change the language, the theme or the start day of my budget month?

The language button is in the top bar. The theme and the day your budget month starts are in Settings. CapBudget is available in English, French, German, Spanish, Portuguese and Italian.

How do I remove the sample data?

Settings → Sample data → Remove sample data. Only the sample transactions are removed, never your own.
