Privacy Policy
Last updated: April 26, 2026
This policy covers the VaporCalc website (vaporcalc.com) and the Is It Worth It? browser extension.
What data we collect
VaporCalc website
VaporCalc runs entirely in your browser. All calculator inputs, wishlist items, savings data, and quiz progress are stored in your browser's localStorage. None of this data is sent to any server. We do not have accounts, logins, or user profiles.
Is It Worth It? extension
The extension stores your watchlist, savings scoreboard, and settings in your browser's local storage (chrome.storage.local). This data stays on your device and is never transmitted to VaporCalc or any third party.
When you click the extension icon, it reads the current page to detect product names and prices. This detection runs locally in your browser — no page content is sent to any external server. The extension uses these permissions:
- activeTab — Read the current page (only when you click the extension icon) to detect product names and prices.
- scripting — Inject a content script into the active tab to extract product information from the page DOM.
- tabs — Detect tab changes to clear the notification badge.
- storage — Save your watchlist, savings, and settings locally in your browser.
- alarms — Schedule desire-check reminders after your configured wait period.
- contextMenus — Add a right-click menu option to add selected text to your watchlist.
- notifications — Show a browser notification when your wait period ends.
What data we do not collect
- We do not collect personal information (name, email, address, payment info).
- We do not track your browsing history or the pages you visit outside VaporCalc.
- We do not use cookies. Application Insights is configured with cookies disabled.
- We do not sell, share, or transmit any data to third parties for advertising or marketing.
Third-party services
The website uses the following third-party services:
- Azure Application Insights — Collects anonymous page-view telemetry (pages visited on VaporCalc, browser type, general location derived from IP address). Cookies are disabled. No personal information is collected. Data is sent to Microsoft Azure servers. See Microsoft's privacy documentation.
- Google Fonts — Loads the Orbitron and Rajdhani typefaces. Google may log standard web request data (IP address, user agent).
- Chart.js CDN — Loads the charting library. The CDN provider may log standard web request data.
Data sync between extension and website
If you have the extension installed and visit vaporcalc.com, the extension syncs your watchlist and savings data between chrome.storage.local and the site's localStorage. This sync happens entirely within your browser — no data leaves your device.
Data deletion
You own your data. To delete it:
- Website data: Clear your browser's localStorage for vaporcalc.com, or use your browser's "Clear site data" feature.
- Extension data: Right-click the extension icon → "Manage extension" → "Clear storage", or uninstall the extension.
