Using the calculator

Terms of Use

Last updated September 26, 2026

These terms describe use of Compound. and its calculation features. Read them together with the Privacy Policy and the app license applicable to your App Store download.

Educational estimates

Compound. produces hypothetical projections from the values and assumptions you enter. Results are educational estimates, not investment, financial, tax, accounting, or legal advice. The app does not recommend a particular investment or execute transactions.

Actual outcomes may differ because of changing returns, contribution timing, fees, taxes, inflation, market conditions, and other factors. Charts, goals, milestones, and time-to-double estimates are not promises of future performance. No return or financial outcome is guaranteed.

Check your inputs and independently verify calculations before relying on them. Seek qualified advice suited to your circumstances when making financial decisions.

Premium and purchases

Optional Premium features are offered through an Apple in-app purchase. The App Store purchase confirmation displays the applicable price and purchase terms. Premium is presented as a one-time purchase, not an automatically renewing subscription.

Apple handles payment and purchase records. Use Restore Purchases in the app with the Apple account used for the purchase. Availability of restored features depends on a valid entitlement. Billing or refund requests are handled through Apple Support and Apple’s applicable policies.

App license and your rights

Unless the App Store listing supplies a different applicable license, the app is licensed under Apple’s Standard End User License Agreement. These calculator-use terms do not replace that license or limit rights that applicable consumer law does not allow to be excluded.

Saved results and availability

You control the calculations you save and the results you share. Keep a separate copy of information you need. Features and calculations may change as the app is updated, and uninterrupted availability or error-free results are not guaranteed.

External services

Advertising, purchase services, and websites opened from the app are operated by their respective providers. Their applicable terms and privacy policies also govern your use of those services.

Questions and updates

For questions about the app, email compoundcalcapp@gmail.com or visit Compound. Support. Revised terms will be posted here with an updated date.
