Personal Finance

Gravity Fintracker

A quantum-encrypted, privacy-first expense tracker. Every transaction stays on your device — no ads, no analytics, no cloud required. See the full story →

  • 100% local by default. Your balances and transactions never leave your device unless you turn on sync yourself.

Privacy by design

We don't want your data.

We don't collect, store or sell your information, and we run no servers to do so. Google AdMob serves ads inside Gravity Send, Gravity Torrent and Gravity Installer — Gravity Fintracker carries no ads or third parties at all.

Zero collection

No analytics SDKs, no telemetry, no profiles. We never see what you transfer or download.

No servers

We operate no backend. There is nowhere for your data to be stored, because we built nowhere to store it.

AdMob, disclosed

Google AdMob shows ads in the mobile apps and may use a device ad identifier. That's the one exception — and we're upfront about it.

You're in control

Reset or limit ad personalization in your OS settings any time. Full details live in each app's policy.
