Strictly necessary
The service uses cookies and related browser storage mechanisms. The personal access key is retained in localStorage so that the subscription can be checked on subsequent visits. The administrator session is stored separately. Necessary storage serves access and security, not advertising tracking.
Display preferences
The choice to enable or disable visual effects is retained in localStorage. sessionStorage records that the introductory screen has been displayed so that it is not repeated within the same session. Your language choice (Greek or English) is also retained in localStorage.
Payments
During payment, Paddle may set its own cookies in accordance with its own policy.
The service uses sessionStorage for a pending transaction identifier and a secret for verifying key issuance. This links purchase completion to the browser that initiated it. PULSHEX does not store card details.
Notifications
With your permission, a service worker and a Web Push subscription are registered on the device. Notifications are not enabled by purchase alone. You may withdraw permission through browser settings.
Analytics / advertising
We do not use advertising cookies. If statistical cookies are added, your consent will be requested first.
Managing storage
You may delete cookies and website data through your browser. This may remove the stored key, session and preferences; keep your key before deleting them. Deleting data on the device does not cancel the subscription or automatically delete data retained by the service.
