Cookie Policy

Last Updated: April 1, 2026

1. What are cookies?

Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, or work more efficiently, and to provide information to the site operators. Cookies may be stored for the duration of your browser session (“session cookies”) or for a defined period after your session ends (“persistent cookies”).

2. How we use cookies

AdBudgetBuddy uses cookies for the following purposes:

  • Essential / Strictly necessary: To authenticate users and maintain secure sessions. Without these cookies, the application cannot function.
  • Analytics: To understand how users interact with the product, which features are used most, and where usability problems occur. This helps us improve the service.
  • Preferences: To remember your settings (such as dark mode and sidebar state) so you do not have to reconfigure them on each visit.

We do not use advertising cookies, retargeting cookies, or third-party tracking cookies for behavioral advertising.

3. Essential cookies (always active)

These cookies are necessary for the platform to operate. They cannot be disabled without breaking the service. They do not track personally identifiable information beyond what is necessary to maintain your authenticated session.
