Privacy Policy

Effective date: September 9, 2025

TL;DR: Calcuria does not collect, sell, or share your personal data. Favorites are stored in Chrome sync. Calculator data is cached locally. No analytics, no ads, no tracking.

What this policy covers

This Privacy Policy applies to the Calcuria – Smart Calculators Chrome Extension ("Extension") published by Calcuria. It explains what limited data is processed and how.

Data we process

  • Favorites: Stored in chrome.storage.sync (tool IDs only). This syncs across your Chrome profile.
  • Calculator list cache: API responses are cached in chrome.storage.local for faster loading. This cache contains only public tool data from calcuria.com.

What we do not collect

  • No names, emails, or personal identifiers
  • No cookies, analytics, or tracking pixels
  • No financial, health, or sensitive data
  • No advertising identifiers

How the extension works

The extension fetches the latest calculator list from https://calcuria.com/api/tools.v1, displays tools by category, and lets you open them in a new tab. Favorites are stored locally. Background alarms refresh the list every few hours.

Permissions we request

  • storage – to save favorites and cache the calculator list.
  • alarms – to refresh cached data automatically.
  • tabs – to open calculators or Calcuria.com in a new tab.
  • host_permissions – restricted to https://calcuria.com/* for fetching the calculator list.

Data retention & security

All data remains in your browser. Favorites and cache can be cleared at any time via Chrome settings. No data is transferred to our servers beyond fetching the public calculator list.

Children’s privacy

This extension is not directed to children under 13. We do not knowingly collect any information from children.

Changes to this policy

We may update this Privacy Policy occasionally. The latest version will always be available at https://calcuria.com/privacy.
