Privacy Policy

Overview

CalNote is a notepad-style calculator that runs entirely in your browser. We are committed to being transparent about what data we collect and how we use it.

Your calculations and data stay on your device. All boards, variables, and settings are stored in your browser's local storage and are never sent to our servers.

Data we collect

CalNote does not require an account, login, or any personal information to use. We do not collect your name, email address, or any personally identifiable information.

We use the following anonymous analytics services to understand how the app is used and to improve the experience:

• PostHog — collects anonymous usage events such as page views and clicks. No personal profiles are created. PostHog helps us understand which features are used and how users navigate the app.
• Microsoft Clarity — records anonymous session replays and heatmaps to help us understand user interactions with the interface. No personally identifiable information is collected. See Clarity's privacy disclosure.
• Pirsch — a privacy-focused, cookieless analytics service that collects anonymous page view statistics. No personal data is collected and no tracking cookies are set.
• Umami — a privacy-focused analytics service that collects anonymous page view statistics. It does not use cookies and does not collect personal data.
• Google Ads (gtag.js) (landing page only) — used to measure the effectiveness of our advertising campaigns. Google may use cookies to track ad conversions and serve relevant ads. No personal data from CalNote is shared with Google. See Google's privacy policy.

Cookies and local storage

CalNote uses local storage (not cookies) to save your boards, theme preference, and active board selection. This data never leaves your browser.

Our analytics services may use cookies or similar technologies for anonymous session tracking. These do not contain personal information and are not used for advertising or cross-site tracking.

Data sharing

We do not sell, rent, or share any data with third parties for advertising or marketing purposes. Anonymous analytics data is only accessible to the CalNote team through the analytics platforms listed above.

Data retention

Your local data (boards, settings) is stored in your browser until you clear it. Anonymous analytics data is retained according to each service provider's standard retention policies.

Your rights

Since we do not collect personal data, there is no personal data to access, correct, or delete. You can clear all CalNote data at any time by clearing your browser's local storage for the app domain.

Children's privacy

CalNote does not knowingly collect any information from children. The app does not require an account and does not collect personal data from any user regardless of age.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated "last updated" date.
