Privacy Policy

1. About This Site

PS-Calculation operates the website ps-unit-converter.vercel.app (the "Service"), a free online unit converter tool supporting Temperature, Weight, Length, Volume, and Currency conversions.

2. Information We Collect

We do not collect, store, or process any personally identifiable information on our servers. Specifically:

• No user accounts or registration
• No forms that collect personal data
• No cookies set by us directly
• Conversion history and favorites are stored locally on your device (localStorage) and never sent to any server

3. Google Analytics

We use Google Analytics to understand how visitors use our site. Google Analytics collects:

• Pages visited and time spent
• Device type (mobile/desktop) and browser
• General geographic location (country/city level)
• Referring websites

This data is anonymized and aggregated — we cannot identify individual users. Google Analytics may use cookies on your device. You can opt out via Google Analytics Opt-out.

4. Google AdSense

• Use cookies to serve ads based on your prior visits to our site or other sites
• Use the DoubleClick cookie to serve interest-based ads

You may opt out of personalized advertising by visiting Google Ads Settings.

Our AdSense publisher ID: ca-pub-8098797773937516

5. Cookies

We do not set cookies directly. Third-party services (Google Analytics, Google AdSense) may set cookies on your device as described in their respective privacy policies. You can control cookies through your browser settings.

6. Local Storage

Our app stores the following data only on your device using browser localStorage:

• Conversion history (last 10 conversions)
• Favorite unit pairs
• Language preference
• Dark/light theme preference
• Tab order preference

This data never leaves your device and can be cleared by clearing your browser's site data.

7. Third-Party Services

Our site is hosted on Vercel. Vercel may collect server logs including IP addresses for security and performance purposes. See Vercel's Privacy Policy.

8. Children's Privacy

Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the Service after changes constitutes acceptance of the new policy.

10. Your Rights & Data Control

Since PS-Calculation stores all preference data locally on your device only, you retain full control at all times:

• Clear history: Use the "Clear" button inside the app
• Clear all local data: Go to your browser settings → Clear site data for ps-unit-converter.vercel.app
• Opt out of Analytics: Use Google Analytics Opt-out
• Opt out of personalized ads: Visit Google Ad Settings

We do not store personal data on any server, so there is nothing to request deletion of from our side.
