Data Deletion Request

If you would like us to delete data associated with your use of Calcdraw Calculator, please follow the steps below. Most of your data is stored locally on your device and is automatically removed when you uninstall the app.

How to request deletion

  1. Uninstall the app from your Android device. This removes all local canvases, formulas, templates, and settings stored in the app's local database.
  2. If you have made an in-app purchase and want us to remove the purchase token from our verification backend, send an email to SilasTawn@outlook.com with:
    • The Google Play order ID (starts with GPA.)
    • A clear statement that you want your purchase data deleted
  3. We will process your request within 30 days and confirm by email once completed.

What data do we hold?

Calcdraw Calculator is offline-first. We do not operate user accounts and do not centrally store your calculations, canvases, or personal files. The only server-side data we may hold is the Google Play purchase token temporarily used to verify your Pro entitlement. This is deleted as soon as it is no longer needed for verification.
