1. Introduction & Overview
Welcome to D&D HP Calculator (https://dndhpcalculator.com). Your privacy is important to us. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website.

5. Google AdSense & Advertising
We use Google AdSense to display advertisements on our website. Google AdSense is a third-party advertising service provided by Google LLC.
How AdSense Works

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits. This includes:

- Interest-based advertising cookies
EU Users: Under GDPR, we request consent before loading personalized ads. You may see a cookie consent banner when first visiting our site. You can withdraw consent at any time.
6. Local Storage & Browser Data
Some of our tools (Spell Slot Tracker, Character Sheets) use your browser's localStorage to save your data for convenience. Here's what you should know:
- Data stays on your device: localStorage data never leaves your browser and is not transmitted to our servers
- Not accessible by us: We cannot see, access, or retrieve any data stored in your browser's localStorage
- Clearing data: Clearing your browser cache/cookies will erase localStorage data
- Optional: You can use all tools without saving data — simply don't click "Save" buttons
