Privacy Policy

Overview

BingoStamp is a free web application for creating and sharing custom Bingo cards. We are committed to being transparent about the data we collect and how it is used.

Data We Store Locally

BingoStamp stores the following data in your browser's local storage. This data never leaves your device and is not sent to any server:

• Your created Bingo cards
• Game statistics (wins, streaks, achievements)
• App preferences (dark mode, sound, haptics)

Advertising & Cookies

BingoStamp displays ads through Google AdSense to support the free service. Google and its partners may use cookies and similar technologies to:

• Serve ads based on your interests and prior visits to this or other websites
• Measure ad performance and frequency
• Prevent the same ad from showing too often
• Detect and prevent fraud

If you are visiting from the European Economic Area, the United Kingdom, or Switzerland, a consent banner from Google's Certified Consent Management Platform (CMP) will appear on your first visit. You can consent, decline, or manage specific purposes and vendors under the IAB Transparency & Consent Framework (TCF v2.2). If you decline, Google will not use cookies for personalized advertising, though limited non-personalized ads may still be shown.

You can learn more about how Google uses data at Google's partner policy page.

Your Choices

• Change your consent (EEA/UK/CH): Use the "Privacy & cookie settings" link that Google's CMP adds to revisit your choices at any time.
• Clear your data: You can clear all locally stored data by clearing your browser's site data for BingoStamp.
• Opt out of personalized ads: Visit Google Ads Settings to manage your ad personalization preferences.
• Block ads in your browser: Ad blockers will prevent AdSense scripts from loading. The app works fully without ads.

No Account Required

BingoStamp does not require sign-up. We do not collect names, email addresses, or any other personal information. Card data is encoded directly in shareable URLs — no server storage is involved.
