Gradlet App: Privacy Policy

Last updated: November 7, 2026

This privacy policy explains how the Gradlet app for Android (package com.worksheet365.grader), a grading calculator for teachers made by Worksheet365, handles your information.

The short version

  • Your grades stay on your phone. Worksheet365 never receives them.
  • There is no account and no sign-in.
  • The app never asks for student names: papers are numbered.
  • The app shows a small banner ad and, rarely, a full-screen ad after you finish a stack, from Google AdMob. To show and measure ads, Google may collect some device data (see “Ads” below).
  • Worksheet365 itself does not run analytics or tracking.

What stays on your phone

Test names, number of questions, scores, classes and subjects, your grading scale and your settings are saved only on your device. We (Worksheet365) do not receive them, and they are not sent to any server. They are deleted if you uninstall the app or clear its data. When you choose to print or share a report (PDF or CSV), you decide where that file goes.

Ads (Google AdMob)

The app shows a small banner at the bottom of the main screens and, rarely, a full-screen ad after you finish a stack (never while grading, at most a few times a day). The Google Mobile Ads SDK may collect and share:

  • the advertising ID of the device;
  • approximate location (from the IP address);
  • app interactions with the ads;
  • diagnostics, such as crashes and performance.

This data is used for advertising, analytics and fraud prevention, and is encrypted in transit. Ads are limited to content suitable for general audiences. Learn how Google uses this data: policies.google.com/technologies/partner-sites.

Your choices

Where the law requires it (for example in the EEA, the UK, Switzerland and some US states), the app asks for your consent before personalized ads, using Google’s consent tool. You can change your choice at any time in the app (Me › Ad privacy choices). You can also reset or delete your advertising ID in your phone settings (Google › Ads).

Children

Gradlet is made for teachers and other adults. It is not directed to children under 13 and does not knowingly collect personal information from children.

Security and changes

Because your data stays on your device, it is protected by your phone’s own security (screen lock, encryption). If this policy changes, the new version will appear in the app and on this page, with a new date.
