Cookie Policy

Last updated: 5 June 2026

This policy explains what cookies Waevin uses, why we use them, and how you can manage them. We keep our use of cookies to a minimum.

What are cookies?

Cookies are small text files that a website places on your device when you visit. They are widely used to make websites work correctly, remember your preferences, and help site owners understand how their site is being used.

Cookies do not contain executable code. They cannot damage your device. Some cookies are deleted when you close your browser (session cookies); others remain until they expire or you delete them (persistent cookies).

Strictly necessary cookies

These cookies are required for the platform to function. You cannot disable them. Doing so would prevent you from logging in.

Analytics cookies

Waevin does not currently use any analytics cookies. We do not use Google Analytics, Mixpanel, or any other behavioural tracking service. If we introduce analytics in the future, we will update this policy and obtain consent before setting any analytics cookies.

Third-party cookies

The only third-party cookies set on Waevin are those placed by Stripe for payment processing and fraud prevention. These cookies are strictly necessary for the checkout to function securely.

Stripe

Stripe sets __stripe_mid and __stripe_sid to detect fraudulent payment activity and maintain session state during the checkout flow. Without these cookies, payments cannot be processed.

We do not use Facebook Pixel, Google Ads cookies, or any other advertising or retargeting cookies. We will not introduce these without updating this policy and seeking your consent.

You can control and delete cookies through your browser settings. Note that disabling strictly necessary cookies will prevent you from logging in to Waevin.
