Privacy policy

Sumvoro is designed to provide useful calculations without asking for personal information.

Calculator inputs

Values entered into public calculators are processed in your browser to produce results. Sumvoro does not require an account for public calculators and does not intentionally store those input values.

Analytics

If you allow optional analytics, Sumvoro may collect limited technical and usage information such as visited pages, device type, approximate location, and interaction events. We use it to improve performance, content, and calculator usefulness—not to sell personal information. Our first-party engagement counters store only the UTC day, calculator name, event type (open, use, or print), and a total count. They do not store your entered numbers or a visitor identifier. Hosting security logs may still include request information.

Cookies and local storage

Essential local storage remembers your privacy preference. Optional measurement technology loads only after you choose “Allow analytics.” See the cookie notice for details.

Advertising

Sumvoro does not currently display advertising. If advertising is introduced, this policy and the privacy controls will be updated before personalized or measurement technologies are enabled.

Service providers and security

Hosting, security, and performance services may process basic request information such as IP addresses and browser headers to deliver and protect the site. We use reasonable safeguards and limit access to operational needs.

Your choices

You can change analytics permission at any time using “Privacy choices” at the bottom of the screen. Clearing browser storage also resets the choice.

Changes

We may update this notice when Sumvoro adds features or providers. The revision date above will change when we do.
