Sumfold

Privacy policy

Last updated: 12 November 2026

Sumfold is a calculator app for Android from Anom, the app studio of Zest Plate LLC ("we", "us"). This policy explains what happens to your information when you use Sumfold.

No account, no personal data from you

• You don't need an account to use Sumfold, and we don't ask for your name, email address or any other personal details.
• Sumfold itself includes no analytics. Data that leaves your phone is limited to the ads described below.

Your numbers stay on your phone

• Your calculations, the history of past sums and the numbers you type in the loan, GST and percentage tools are saved only in Sumfold's private storage on your phone, so they're there next time.
• Sumfold does not include them in cloud backups or phone-to-phone transfers. You can clear the history in Settings, and uninstalling Sumfold deletes everything.
• When you tap Share on a loan, Sumfold hands the text you see to the app you choose; nothing is sent until you do.

Ads

Sumfold is free and shows ads from Google AdMob, Google's advertising service: a banner at the top of the calculator and above the tabs on the other tools, and an occasional full-screen ad when you close the payment schedule or Settings.

• To show ads, measure them and prevent fraud, the Google Mobile Ads SDK in Sumfold collects and sends to Google: your device's advertising ID and other device identifiers (such as the app set ID), your IP address (from which an approximate location can be worked out), information about the ads you see and tap, and technical and diagnostic information about your phone and the app (for example the model, Android version, crash reports and performance data).
• The ads never see your calculations or the numbers you type.
• Google may use this information to show personalised ads where the law allows it and you agree, and non-personalised ads otherwise. How Google uses information from apps that use its services: https://policies.google.com/technologies/partner-sites
• We (Zest Plate LLC) don't receive personal data from the ads. We only see totals, such as how many ads were shown and what they earned.
• Ads in Sumfold are limited to content suitable for general audiences.

Your ad choices

• In the European Economic Area, the UK, Switzerland and US states with privacy laws, Sumfold asks for your choice with Google's consent form the first time you open it. You can change it at any time in Settings > Privacy choices.
• Anywhere, you can reset or delete your advertising ID, or turn off ad personalisation, in your phone's Settings > Google > Ads (on some phones, Settings > Privacy > Ads).

Permissions

• Internet, network state and advertising ID: used by the ads.
• The ads library also adds a few standard permissions that Android grants without asking (for example, keeping the phone awake for a moment to finish a task). Sumfold never asks you for a permission.

Not financial advice

Sumfold's loan, GST and percentage results are estimates to help you plan. They are not financial, tax or legal advice. Your lender's, seller's or tax authority's figures are the ones that count.

Children

Sumfold is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes to this policy

If this policy changes, the new version will be posted on this page with a new date.
