This Cookie Policy explains which cookies and similar technologies MatheJump uses on its website, why we need them, and how you can change your preferences at any time.
Strictly necessary cookies remain active so that sign-in, security, and core functions work reliably. We only enable statistics and marketing cookies if you explicitly agree.
1. What cookies are
Cookies are small text files that your browser stores on your device. They can contain information such as session status, language settings, or consent choices.
Alongside traditional browser cookies, we may use similar storage technologies when they are required for the same purposes. In this policy, we refer to all of them collectively as cookies.
2. Which cookie categories we use
MatheJump distinguishes between three cookie categories. You decide which optional categories are active in the banner or in the settings area at the top of this page.
- Strictly necessary cookies: sign-in, session security, abuse prevention, language preferences, and core site functions.
- Statistics cookies: audience measurement, usage analysis, and product improvement.
- Marketing cookies: relevant offer messages, campaign measurement, and reminder journeys where those features are active.
3. When cookies are set
Strictly necessary cookies are set as soon as you use MatheJump because core functions cannot be provided without them.
Optional cookies are only set after your active consent. If you reject them, MatheJump remains usable, but some analysis or campaign functions stay disabled.
4. Third-party services
For some functions, we work with selected service providers, for example for payment processing or technical measurement. If those services require cookies for statistics or marketing, we enable them only after your consent.
Payment-related flows, for example through Stripe, may require strictly necessary cookies or similar security mechanisms once you start a checkout process.
5. Changing your choice and deleting cookies
You can change your choice on this page at any time. Saved preferences on this device are updated as soon as you save a new decision.
You can also delete or block cookies directly in your browser. Please note that this may limit sign-in, security, or other core MatheJump functions.
6. Contact
If you have questions about this Cookie Policy or about the processing of personal data, contact us at info@mathejump.de or by post at ANEC GmbH, Rügenstraße 19, 40880 Ratingen, Germany.
