This page explains how Histeva uses cookies, localStorage, sessionStorage, server logs and similar technologies.
Cookies are small files stored in a user's browser or device. LocalStorage and sessionStorage are browser storage mechanisms that may be used, for example, to remember settings, login status or certain data needed for the application to function.
These technologies are necessary for the application to function. Without them, it would not be possible to provide, for example, login functionality, session security, storage of cookie preferences, payments or the basic operation of the application.
We do not require consent to use necessary technologies.
Functional technologies may make the application more convenient to use, for example by remembering user choices, loading the application faster or storing certain settings in the browser.
Where these technologies are not necessary for the application to function, we use them only to the extent appropriate for their purpose.
Analytics technologies help us understand how the application is used so that we can improve its features, clarity and stability.
We use Google Analytics 4 to analyse traffic. Before consent is given, only anonymous, non-identifiable data without cookies is sent for the purpose of basic traffic estimation. Full tracking using cookies is activated only after you give your consent, which you can change at any time in the cookie settings.
| Category | Provider | Example technology | Purpose | When used |
|---|---|---|---|---|
| Necessary | Histeva | cookie or localStorage used to store cookie preferences | remembering consent settings | whenever the user makes a choice |
| Necessary | Supabase | authentication tokens, for example items such as sb-*-auth-token | login, session management, account security | during registration and login |
| Functional | Histeva | localStorage / sessionStorage | storing selected settings, faster interface loading | while using the application |
| Necessary technical logs | Vercel | server and operational logs | hosting, security, availability, troubleshooting | when visiting the website and application |
| Payment technologies | Stripe | cookies and similar technologies used in the payment process | payment processing, fraud prevention, transaction security | only when paid features or the payment interface are used |
| Email technical data | Resend | email delivery metadata | sending service and transactional emails | when an email is sent from the application |
The exact names of cookies and browser storage items may change depending on the technical configuration of the application and individual services. We will update this overview on an ongoing basis to reflect the technologies actually in use.
Necessary technologies are used in particular to provide:
These technologies cannot be disabled without affecting the functionality of the application.
If you use paid features, a subscription or another payment option, the payment provider Stripe may be used.
Stripe may use its own cookies and similar technologies as part of the payment process, in particular to ensure secure payment functionality, verify transactions and prevent fraud.
The operator of Histeva does not have access to full payment card details. These details are processed by Stripe in accordance with its own terms and policies.
We use analytics technologies only if you give us your consent.
You can give, refuse or change your consent at any time in the cookie settings.
Analytics tools track you and store cookies only after you have given your consent. Without consent, only anonymous, non-identifiable data without cookies is sent to Google Analytics for the purpose of basic traffic estimation.
To operate the application, we use technical service providers, in particular Supabase, Vercel, Stripe and Resend.
These services may process technical data necessary to provide their services, such as IP addresses, technical identifiers, request metadata, device data, payment metadata or email delivery metadata.
Details about these providers are set out in the Privacy Policy.
When you first visit the application, you can choose whether you consent to the use of optional technologies, where such technologies are used.
You can change your consent at any time via .
You can also delete cookies and other data stored in your browser through your browser settings. If you do so, the cookie banner or settings may be displayed again.
