Privacy Policy

Last updated: 20 September 2026

Compoundly does not collect any data about you.

What we collect

Nothing. There is no account to create, no sign-in, no analytics, no advertising, no tracking, and no third-party SDKs of any kind. We receive nothing when you use the app, because the app sends nothing.

What stays on your device

The numbers you type into the calculators — time period, amounts, rate, and your choice of settings — are saved on your device so they are still there next time you open the app. They are stored using the operating system's standard app storage, they never leave your device, and they are removed when you delete the app. You can clear them at any time from Settings → Saved inputs → Clear saved inputs.

Network

Compoundly contains no networking code. It does not connect to the internet, and it works entirely offline.

Children

The app collects nothing from anyone, including children. It is rated 4+ and contains no advertising, no purchases and no external links.

Not financial advice

Compoundly is a calculator. Its projections are arithmetic based on the numbers you enter, assuming a constant rate of return. Real investment returns vary year to year and are never guaranteed. Nothing in the app is financial advice.

Changes

If this policy ever changes, the updated version will be posted at this address and the date above will change.
