Support

For Calculator 10 support, email [email protected].

Please include:

• the Calculator 10 version shown by Android;
• your Android version and device or emulator model;
• the calculator or tool you were using;
• the exact steps and input that reproduce the problem;
• what you expected and what happened instead.

Do not send passwords, payment-card information, Google account credentials, private signing material, or unrelated personal data. For a purchase-restoration issue, include the affected product name and approximate purchase date, but do not email full payment details.

Common Checks

• Confirm the app is updated through its existing Google Play listing.
• For currency or speed tools, verify that the device has an internet connection and retry later if the provider is unavailable.
• For a premium restoration issue, confirm Google Play is signed into the account that made the purchase, then reopen the app while online.
• For ad privacy choices, open Settings and use Privacy Choices when that option is available.
