Cookie Policy

This Cookie Policy explains how Omnvert ("we", "us") uses cookies and similar technologies (e.g., local storage, pixels) when you visit our website. It complements our Privacy Policy.

1) What is a cookie?

A cookie is a small text file stored on your device by your browser when you visit a website. Cookies let the site remember your actions and preferences (language, theme, consent), enable security features, measure usage, and — when you allow — show personalized advertising.

2) Categories of cookies we use

2.1 Strictly necessary

Required for the site to function. Examples: load-balancing, security/anti-abuse tokens, remembering your cookie consent choice, route protection. These are first-party and cannot be disabled in our consent banner because the site would not work without them.

2.2 Functional / preference

Remember your interface preferences (language, dark/light theme, calculator inputs you have chosen to save locally). Stored in localStorage in your browser, not sent to our servers unless you submit them as part of a calculation.

2.3 Analytics

We may use privacy-respecting analytics to count page views and understand which tools are popular. Where we do, we use aggregated server logs (IP truncated, no identifiable user profiles). We do not sell or share analytics data with advertisers.

2.4 Advertising (Google AdSense)

When advertising is enabled on a page (e.g., calculator pages), Google AdSense and its partners may set cookies to:

• Show ads relevant to your interests (personalized advertising), if you consent.
• Show non-personalized contextual ads if you do not consent (or in regions where consent is required).
• Measure ad performance, prevent fraud, and limit the number of times you see the same ad.

Google's use of advertising cookies is described at policies.google.com/technologies/ads. You can manage personalization at adssettings.google.com and opt out of third-party vendor cookies via aboutads.info/choices and youronlinechoices.eu.

3) Third-party cookies on our site

• Google AdSense / Google AdSense partners — advertising and frequency capping (only when ads are served).
• Google Analytics — if enabled, anonymous traffic measurement.
• CDN / hosting provider — strictly necessary for content delivery and security.

4) Your choices

• Consent banner: On first visit (in regions where consent is required, e.g., EU/EEA, UK, Türkiye for KVKK), a banner lets you accept, reject, or customize non-essential cookies. You can change your decision anytime by clicking "Cookie settings" in the footer.
• Browser settings: Most browsers let you block or delete cookies. See Chrome, Firefox, Safari, or Edge. Blocking strictly necessary cookies will likely break parts of the site.
• Do Not Track / Global Privacy Control: We honor browser GPC signals where applicable.

5) Legal basis (GDPR, UK GDPR, KVKK)

• Strictly necessary cookies — legitimate interests (Article 6(1)(f) GDPR; KVKK Article 5(2)(f)).
• Functional, analytics, advertising cookies — your consent (Article 6(1)(a) GDPR; KVKK Article 5(1) — explicit consent for non-essential processing).
• For users in Türkiye, KVKK (Personal Data Protection Law No. 6698) requires explicit consent for personal data processing. We obtain consent via the cookie banner and provide the option to withdraw consent at any time.

6) Retention

• Session cookies: deleted when you close the browser.
• Preference cookies: typically up to 12 months.
• Analytics cookies: typically up to 13 months (aggregated).
• Advertising cookies: typically up to 13 months, set by third-party advertisers.

7) Children

The site is not directed to children under 13 (under 16 in some jurisdictions). We do not knowingly collect personal data from children. If you believe a child has provided personal data, contact us and we will delete it.

8) Changes to this policy

We may update this Cookie Policy as our practices or applicable laws change. We will revise the "Last updated" date above. Material changes will be highlighted on the site.
