This Cookie Policy is an integral part of the Privacy Policy and covers the use of cookies and similar technologies between your device and PowerLibs.
1. What Are Cookies?
A cookie is a small piece of data sent from a website and stored on your device by your web browser. Cookies help websites function efficiently, remember login states, store preferences, and analyze website traffic. Some cookies expire when you close your browser (session cookies), while others persist for a set period (persistent cookies).

The following table lists all cookies and similar storage technologies used on powerlibs.com:
| Name | Provider | Category | Purpose | Duration |

3. Consent and Control
Cookies categorized as Analytics or Feedback are strictly opt-in. They are only set after you give explicit consent through the cookie consent banner displayed on your first visit.
Essential cookies are required for basic website functionality (authentication, storing your consent preference). These cannot be disabled, as the site would not function without them.
To change your cookie preferences at any time:
- Click "Cookie Settings" in the website footer
- Use the "Manage preferences" section to toggle individual categories on or off
- Click "Save Preferences" to apply your changes
Consent is automatically renewed every 6 months. After that period, the cookie banner will reappear so you can confirm or update your preferences.
4. What PowerLibs Does Not Do
- PowerLibs does not use advertising or retargeting cookies.
- PowerLibs does not sell or share cookie data with third parties for commercial purposes.
- PowerLibs does not use cookies to build advertising profiles.
- PowerLibs does not track you across other websites.
5. Managing Cookies via Browser Settings
You can also manage or delete cookies directly through your browser settings. Please note that disabling essential cookies may affect website functionality.
