Privacy Policy
This Privacy Policy explains how Voyager Tecnologias LTDA ("we", "us") collects, uses, and shares information when you use Units Converters.
Last updated: 13 July 2026
Who we are
Units Converters is operated by Voyager Tecnologias LTDA, based in Brazil. For privacy questions, contact voyagertecnologias@gmail.com.
Information we collect
We aim to collect only what we need to run and improve the site:
- Usage data: pages viewed, approximate location derived from IP, device/browser type, and referral information — typically via analytics tools after you consent.
- Consent preference: whether you accepted or declined non-essential cookies, stored in your browser (localStorage).
- Feedback you send: name, email, and message if you use our contact or feedback forms.
- Advertising data: when ads are enabled after consent, Google AdSense and partners may process cookie and device identifiers to show and measure ads.
Cookies and similar technologies
Essential storage keeps your language and consent choices working. Non-essential cookies for analytics and advertising load only after you click "Accept All" on our cookie banner. You can change your mind anytime via "Cookie settings" in the footer.
Google AdSense and other advertising
We use Google AdSense to display advertisements. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites, subject to your consent choices. You can learn more in Google's Advertising policies and manage ad personalization at Google Ads Settings.
We may also use contextual networks such as Media.net, and optional affiliate links (for example Amazon Associates) on guide pages. Affiliate partners may set cookies when you follow those links. See our Disclaimer for commission disclosure. These partners only load after you accept cookies where consent is required.
Analytics
If you accept cookies, we may use PostHog (posthog.com) to understand how people use Units Converters—for example, which pages are popular, approximate region, and basic device or browser information. PostHog processes this data on our behalf so we can improve the site. Analytics is disabled when you decline cookies. Learn more in PostHog's Privacy Policy.
How we use information
- To operate, secure, and improve the converter and guides
- To respond to contact and feedback messages
- To show relevant advertising when you have consented
- To comply with legal obligations
Sharing of information
We do not sell your personal information. We share data with service providers who help us run the site (hosting, email delivery for forms, analytics, and advertising partners such as Google) under appropriate agreements. We may disclose information if required by law.
Data retention
Consent preferences stay in your browser until you clear site data or change them. Feedback messages are kept only as long as needed to respond and improve the service. Analytics and advertising retention follow each provider's policies.
Your rights
Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal data, and to object to certain processing or withdraw consent. To exercise these rights, email voyagertecnologias@gmail.com. You can also decline non-essential cookies at any time.
Children
Units Converters is a general-audience educational tool. We do not knowingly collect personal information from children under 13 (or the equivalent age in your region). If you believe a child provided data, contact us and we will delete it.
International transfers
Our hosting and partners may process data in countries other than yours. Where required, we rely on appropriate safeguards offered by those providers.
Changes to this policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will change when we do. Continued use of the site after changes means you accept the updated policy.
