Privacy Policy
Effective Date: May 12, 2026 | Applies to all Numinad domains and supported regional portals.
What You Need to Know First
Numinad is a car rental price comparison platform. We do not process bookings, handle payments, or store credit card numbers, banking credentials, or personal identification documents. When you click through to a rental provider, all payment processing and personal data collection for the booking occurs on that provider's platform, under their privacy policy. This policy describes only what Numinad collects on our own platform.
We are committed to collecting only the minimum data necessary to operate a fast, accurate car rental comparison service. We do not sell your personal information to third parties.
Information We Collect
To deliver real-time car rental price comparisons and maintain a secure, high-performance platform, Numinad collects the following categories of information:
- Car Rental Search Parameters: Pickup location, drop-off location, rental start and end dates and times, vehicle class preferences, and driver age where applicable. This data is used solely to query our provider network and display relevant results.
- IP Address (Server-Side): Your public IP address is processed server-side through our `/api/geo` geolocation endpoint to determine your approximate country or region, enabling automatic locale detection (e.g., redirecting to the `/us` or `/gb` market portal). IP addresses are not stored in persistent logs beyond the duration of the session.
- Browser and Device Information: Standard HTTP headers including `User-Agent` string, browser type and version, operating system, screen resolution, and preferred language. This data is used to optimize the interface for your device and to satisfy anti-abuse verification requirements on upstream provider APIs.
- Locale and Currency Preferences: Your selected market portal (e.g., `/fr`, `/de`) and currency setting, stored in session-level browser storage to maintain a consistent search experience.
- Affiliate Tracking Parameters: Outbound links to Kayak, Skyscanner, Expedia, and other partners include tracking identifiers (such as a `subId` parameter) that allow us to attribute affiliate commissions. These identifiers are session-based and do not contain personally identifiable information.
- Recent Searches: If you use the 'recent searches' feature, your recent pickup locations and dates are stored in your browser's `localStorage` on your own device. This data never leaves your device and is not transmitted to our servers.
- Voluntary Contact Information: If you contact us via email at numinad-support@gmail.com, we retain the content of your message and your email address solely to respond to your inquiry.
Information We Do Not Collect
It is equally important to be explicit about what Numinad does not collect or process:
- Payment Information: We never collect, transmit, or store credit card numbers, debit card numbers, bank account details, or any other financial payment credentials. All payment processing occurs on the rental provider's platform after you click through.
- Booking Confirmation Data: Numinad does not receive or store your booking confirmation numbers, reservation details, or driver's license information. These are collected by the provider at checkout.
- Persistent User Accounts: Numinad does not require account registration. We do not maintain permanent user profiles or long-term records linked to individual identities.
- Sensitive Personal Data: We do not collect health information, government identification numbers, biometric data, or any data classified as sensitive under GDPR Article 9 or equivalent regulations.
How We Use the Data We Collect
Data collected on the Numinad platform is used exclusively for the following purposes:
- Delivering Car Rental Search Results: Your search parameters are forwarded to our provider API network to retrieve live pricing and availability from Kayak, Skyscanner, Expedia, and other platforms.
- Geolocation and Locale Detection: IP-based geolocation routes you to the correct regional portal and displays prices in your local currency. This lookup is performed server-side and the result (a country code) is used transiently to set your locale; the raw IP is not stored beyond the request.
- Platform Security and Anti-Abuse: Browser headers and IP addresses are used to enforce rate limiting on our API proxy routes (30 requests per minute per IP) and to detect and block automated abuse of our search infrastructure.
- Affiliate Commission Attribution: Tracking parameters embedded in outbound links allow our affiliate partners (Kayak, Skyscanner, Expedia, Agoda, etc.) to attribute completed bookings to Numinad and pay us a referral commission. These parameters do not transmit your personal information.
- Performance Monitoring and Error Diagnosis: Anonymous usage metrics (page load times, error rates, API response latency) help us identify and fix performance issues. No personally identifiable information is included in these metrics.
- Legal Compliance: In limited circumstances, we may process data to comply with applicable law, respond to valid legal process, or protect the rights and safety of our users and platform.
Third-Party Provider Redirects and Their Privacy Policies
A core part of Numinad's service is redirecting you to third-party car rental booking platforms when you select a deal. When you click a 'View Deal' or 'Book Now' button:

- We strongly recommend reviewing the privacy policy of any provider you book through before completing a reservation.
Data Retention
Numinad is designed to minimize data retention. Our specific retention practices are as follows:
- Search Parameters: Processed in real-time to fetch results and not stored in any persistent database linked to your identity.
- IP Address and Geolocation: Used transiently for locale detection and rate limiting. Server access logs, if retained for security purposes, are kept for a maximum of 30 days and then deleted.
- Recent Searches (localStorage): Stored exclusively in your browser on your own device. Numinad never copies this data to our servers. You can delete it at any time by clearing your browser's local storage.
- Email Correspondence: Messages sent to numinad-support@gmail.com are retained for up to 24 months to allow follow-up on ongoing support matters, then permanently deleted.
- Affiliate Tracking Parameters: Session-based. Not stored in persistent databases on our end.

Children's Privacy
Numinad is not directed to individuals under the age of 18. We do not knowingly collect personal information from children. Car rental services require drivers to be at least 18 years old (or 21 in many markets), and our platform is designed for adult users accordingly.
If you believe a child under 18 has provided personal information to Numinad, please contact us immediately at numinad-support@gmail.com and we will take steps to delete such information.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make material changes, we will update the 'Effective Date' at the top of this page. We encourage you to review this policy periodically.
Your continued use of the Numinad platform after any changes become effective constitutes your acceptance of the updated policy.
