Privacy Policy Calculators App

Effective July 14, 2026

This Privacy Policy describes how IMUSE INC ("we," "us," or "our") handles information in connection with the Calculators app for iOS, Android, and macOS (the "App"). We wrote this to be readable, not lawyerly. If something is unclear, email us.

What we collect — the short answer: nothing, by default

Every calculator in the App runs entirely on your device. No inputs, results, or usage data are transmitted to our servers or any third party as part of normal use unless you deliberately share a calculation as described below. The App does not require an account. It does not embed analytics or third-party measurement SDKs. The current release is declared as Data Not Collected in Apple's App Store and as collecting and sharing no user data in Google Play.

On-device data

The App may store the following data on your device only:

• Favorites and last-used inputs — calculators you favorite and the most recent values the App restores for your convenience.
• Settings and preferences — display theme, unit preferences, and similar customizations.

This data stays on your device unless you deliberately share it or explicitly enable iCloud sync (see Optional Account & Sync below). You can delete saved favorites and inputs by clearing the App's storage or uninstalling it. iCloud sync, if offered, is available only on supported Apple devices. The Android app excludes its preferences from operating-system cloud backup and device transfer. Uninstalling the App removes its remaining local data.

Sharing a calculation

When you choose Share calculation, the App may create an onlinecalculator.me link whose query parameters contain the calculator values currently shown on screen. The App then gives that link to your device's share sheet. Creating the link does not by itself send the values to us, and the Android App has no internet permission. The app or person you select can read the full link, including those values. If someone opens it, their browser sends the URL to onlinecalculator.me and its hosting infrastructure as an ordinary web request. Review the link before sending it and do not share sensitive values with a recipient you do not trust.

Optional account and cross-device sync

A future version of the App may offer an optional account, including Sign in with Apple, so you can sync favorites and settings across your devices. This feature is strictly opt-in — the App works fully without it. If and when you choose to create an account:

• For Sign in with Apple, we receive only the information Apple provides (typically an anonymized email relay address and a unique identifier). We never see your real Apple ID email unless you choose to share it.
• Your synced favorites and settings are stored on our servers solely to provide the sync service and are not used for any other purpose.
• You can delete your account and all associated data at any time from within the App or by contacting us at [email protected].

Until this feature is released and you opt in, no account data exists and this section does not apply to you.

Optional promotional content and third-party links

The App may display optional informational cards — for example, current mortgage rate offers or financial product suggestions — alongside relevant calculators. The calculator engine itself remains on-device. Specifically:

• On supported versions, the App may fetch a static first-party configuration file from onlinecalculator.me. This request contains no calculator inputs, results, or app-generated identifiers, but it may disclose your IP address and device type to our content-delivery infrastructure. The initial Android release does not make this request and does not request internet access.
• If promotional cards are enabled, their content may be fetched over the network when you view a screen that includes them. Promotional content and event reporting are disabled in version 1.0.
• Cards may link to third-party websites or services. Once you leave the App, those third parties' own privacy policies apply. We are not responsible for their data practices.
• We do not receive or store any information about whether you tap or convert on a third-party offer; any such tracking is governed solely by the third party's policy.

Promotional cards are clearly labeled in the UI. The calculator itself always runs offline regardless of whether you interact with a promotional card.

Children's privacy

The App is not directed to children under 13. We do not knowingly collect personal information from anyone under 13. If you believe a child has provided personal information through an optional feature, please contact us at [email protected] and we will delete it promptly.

Data security

On-device data is protected by the standard app sandbox and operating-system protections on iOS, Android, and macOS. Any server-side data associated with an optional account is transmitted over TLS and stored with industry-standard protections. No security measure is perfect; we cannot guarantee absolute security, but we take reasonable precautions.

Changes to this policy

If we make material changes, we will update the Effective Date above and, for significant changes, provide notice within the App or by email (if you have an account). Continued use of the App after a change takes effect constitutes your acceptance of the revised policy.
