2. Scope

This policy applies to numbkit.com ("the site") and explains what data we collect, how we use it, and the rights granted to you under the laws applicable to your jurisdiction, including:

3. What We Collect

Our calculators run entirely in your browser. We do not require accounts, do not store your inputs on our servers, and do not maintain a user database.

However, the following third-party services automatically collect limited data when you visit:

4. Data Processing Agreements

We rely on Data Processing Agreements (DPAs) with our technology providers (Cloudflare, Google) included in their standard service terms. These agreements ensure that data processing is limited to the purposes described in this policy and that adequate safeguards are in place for international transfers, including Standard Contractual Clauses where applicable.

5. Cookies and Consent

We use a Consent Management Platform (CMP) compatible with the IAB TCF v2.3 framework to comply with GDPR (EU/UK), CCPA (California), and similar regulations. On your first visit you can choose:

You can withdraw your consent at any time, with the same ease with which it was granted, via the consent link in the footer. Our CMP also honours the Global Privacy Control (GPC) signal where supported by your browser.

6. Google AdSense — Ad Technology Partners

We participate in Google AdSense's automated optimization of advertising technology partners (ATP). Google may experiment with different ad-tech vendors that comply with 2026 privacy standards. You can review and manage the full list of these partners at any time through our cookie preference centre.

7. Google Analytics 4

Since 28 April 2026, this site uses Google Analytics 4 (Measurement ID G-ELMHW6VKZB) to understand how visitors interact with our calculators. Analytics is operated by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland), acting as our data processor under a Data Processing Agreement compliant with GDPR Articles 28 and 46. The DPA was accepted by the data controller on 29 April 2026.

Cookies set by Google Analytics:

Data collected: pages visited, time on page, approximate geographic location (country and region — never street-level), device type and browser, referral source. IP addresses are processed only in aggregate and are not stored individually.

Your opt-out options:

This GA4 property has Google's standard data-sharing settings enabled (Google products & services, modeling contributions, technical support, account specialists). You can review Google's data practices in the Google Privacy Policy.

8. Notice at Collection (California Residents — CCPA/CPRA 2026)

At the moment of your access to this site, we collect:

These categories are "shared" with Google AdSense and Google Analytics for the purposes of cross-context behavioural advertising and traffic analytics. Retention periods: security logs 30 days; analytics cookies up to 2 years; advertising cookies per the preferences set in our CMP. You have the right to opt out of the sale or sharing of your personal information through the "Do Not Sell or Share My Personal Information" link in our footer, or by activating Global Privacy Control in your browser.

9. Your Rights

Depending on your jurisdiction, you have the right to:

Mexico — LFPDPPP: Mexican users may exercise their ARCO rights (Acceso, Rectificación, Cancelación, Oposición) or revoke their consent for advertising purposes by writing to [email protected]. Requests are answered within 20 business days as required by the Secretaría Anticorrupción y Buen Gobierno (the regulatory authority that replaced INAI on 21 March 2025 under the new LFPDPPP).

10. Para Usuários no Brasil (LGPD)

Em conformidade com a Lei Geral de Proteção de Dados (Lei 13.709/2018), garantimos aos titulares brasileiros os direitos de confirmação da existência de tratamento, acesso, correção, eliminação, portabilidade e oposição. O canal de comunicação para questões de privacidade é [email protected].

11. Affiliate Links

Some links on NumbKit are affiliate links — primarily to Binance. If you sign up through one of these links and complete certain actions, we may receive a commission at no extra cost to you. Affiliate links are marked with rel="sponsored" as required by Google's guidelines.

12. Digital Products (Gumroad as Merchant of Record)

If you purchase a digital product from NumbKit, the transaction is processed by Gumroad Inc., who acts as the Merchant of Record. Gumroad is responsible for collecting and remitting any applicable VAT or sales tax in your jurisdiction, and serves as the data controller for purchase information. We do not handle, store, or access payment data. See Gumroad's Privacy Policy.
