Privacy Policy for Rectangular to Polar Coordinates

This Privacy Policy explains how Rectangular to Polar Coordinates ("we", "us", "our") handles information when you use our website and online rectangular to polar coordinates converter.

What Data Rectangular to Polar Coordinates Collects

• Usage data: basic, aggregated metrics (e.g., page views, approximate region, device type) that help us improve performance and UX.
• Server logs: standard web logs (IP address, user-agent, timestamps) used for security and reliability.
• Messages you send: if you contact us via the contact page, we receive the information you submit.
• Cookies/Storage: we may use strictly necessary cookies or local storage to remember simple preferences (e.g., angle mode or precision) and may use analytics cookies where permitted by law.

What we do not collect by default

• No user accounts or passwords are required to use the calculator.
• No payment information is requested.
• We do not ask you to submit government IDs.

Calculator inputs

The calculator updates instantly in your browser. We do not build features to persist your typed values to our servers. We also do not attach numeric inputs (like x, y, r, θ) to your identity. If we later add optional features that share or save inputs, we will clearly explain the behavior and—where required—ask for consent.

How we use information

• Provide, maintain, and improve the calculator and site
• Secure the service, prevent abuse, and troubleshoot
• Respond to messages you send
• Understand aggregate usage to prioritize features

Legal bases (EEA/UK)

• Legitimate interests for basic analytics, security, and service improvement
• Consent where required (e.g., non-essential cookies or optional features)
• Contract/Pre-contract when you contact us and reasonably expect a reply

Retention

Contact messages are kept as long as needed to respond and maintain records. Logs and analytics are kept for a limited period consistent with security and operations.

Sharing

We do not sell your personal information. We may share limited data with trusted service providers that help us run the site (e.g., hosting/CDN, security, analytics), bound by confidentiality and data-protection obligations. We may disclose information if required by law or to protect rights, safety, or integrity of the service.

International data transfers

Our providers may process data in multiple countries. Where required, we use appropriate safeguards (e.g., standard contractual clauses) offered by those providers.

Your choices & rights

• You can use the calculator without creating an account.
• If you're in the EEA/UK, you may have rights to access, correct, delete, or restrict processing of your personal data. To exercise rights, contact us via the contact page.
• California residents may have rights under the CCPA/CPRA and can make a request through our contact page.

Cookies & analytics

We use Google Analytics 4 (provided by Google LLC) to understand aggregate traffic, such as which pages are visited, approximate region, device type, and referring sites. Google Analytics sets first-party cookies (for example _ga) to distinguish visits. We do not send your calculator inputs to Google Analytics.

• Your choice: the cookie banner offers "Accept All" or "Essential Only". Visitors in the EEA, UK, and Switzerland start with analytics and advertising storage switched off (Google Consent Mode) until they accept. Your choice is saved in your browser's local storage under rtp_cookie_consent; clearing site data resets it.
• Opt out of Google Analytics on all sites with the Google Analytics Opt-out Browser Add-on.
• Contact form: messages sent through our contact form are delivered by Web3Forms, which forwards your name, email, and message to us by email.
• Hosting: the site is served through Cloudflare, which processes IP addresses and request logs to deliver and secure the site.
