You probably track where your money goes each month. But do you know where your data goes after you log an expense?

Most budgeting apps sell your financial data regardless of what you pay. The “anonymized” data pitch is questionable at best. Your spending patterns are about as anonymous as your fingerprint.

So what can you do?

Privacy-first alternatives

Basalt

Basalt is new, and it’s built differently. Your financial data stays on your device. No servers collecting transactions, no ads tracking your spending.

How file-based storage works and why it matters for your privacy.

Key features:

  • Local-first storage (your data never leaves your device)
  • File-based (text files you own)
  • iCloud sync using your infrastructure, not theirs
  • Free tier that actually works
  • AI features that don’t require sharing your data (bring your own Google Gemini key - free)

If you want a budgeting app that treats privacy as a feature, not an afterthought, check out Basalt at basaltapp.com.

Actual Budget

Actual Budget is open-source and self-hosted. You’ll need to run it on your own server, which means your data stays with you.

Pros:

  • 100% self-hosted
  • Active open-source community
  • Powerful budgeting methodology

Cons:

  • Requires technical setup
  • Web only, no mobile app

You can find Actual Budget at actualbudget.com.

Firefly III

Firefly III is another self-hosted option for people who want to track every penny without sharing their financial life with anyone.

Pros:

  • Completely self-hosted
  • Feature-rich
  • Good for DIY types

Cons:

  • Installation needs some tech know-how
  • Interface works but isn’t pretty

Check out Firefly III at fireflyiii.org.

Why it matters

Your financial data reveals a lot about you:

  • Your income level
  • Your spending habits
  • Your health issues (pharmacy purchases say a lot)
  • Your relationship status
  • Your travel plans
  • Your financial vulnerabilities

Targeted advertising is annoying. Targeted financial manipulation is dangerous.

The short version

You don’t have to choose between modern budgeting features and privacy. The apps above prove you can have both. Basalt stands out for balancing ease-of-use with genuine privacy-first architecture.

Your financial data should stay yours.
