Privacy Policy

1. Information we collect

We may collect limited operational data: page views, aggregate usage, browser/device type, and anonymous performance/error telemetry.

There is no account system in this release.

2. Tool input handling

Tool input runs locally in your browser whenever possible. In normal operation, pasted values, JSON, and text are not uploaded or stored by Calctrove.

Avoid submitting production secrets, private keys, or regulated personal data into public tools.

3. Cookies and advertising

We may use cookies or similar technologies for analytics, reliability, and ad delivery. Ad slots are separated from tool controls. When ad providers are enabled, they may process identifiers and interaction signals under their own policies.

Third-party vendors, including Google, may use cookies to serve ads based on prior visits to Calctrove and other websites. Google and its partners may use advertising cookies to personalize, measure, and improve ads depending on your region, settings, and consent choices.

You can opt out of personalized Google advertising in Google Ads Settings. You can also review broader third-party opt-out choices at aboutads.info.

If additional third-party ad vendors or ad networks are enabled, their cookies and opt-out controls will be disclosed through this page or the vendor's own policy links. Ad resources load only after consent when consent is required.

4. Retention and security

We keep limited operational telemetry for maintenance and abuse prevention windows.

Reasonable safeguards are applied, but no internet service can guarantee absolute security.

5. Third-party services

Hosting, analytics, and advertising services may process technical metadata under their own privacy terms.

6. Children's privacy

Calctrove is a general educational utility site and is not directed to children under 13. If child-specific data is shared by mistake, contact us for review and deletion.

7. Policy updates

Policy updates are reflected by revising the effective date on this page.
