Doom Blocker does not collect personally identifiable information. Page content is temporarily processed and stored by our secure AI API solely to apply the filters you define. This data is not stored permanently and is deleted immediately after processing. User filter settings and preferences are saved locally in your browser so your custom filters persist between sessions. No data is shared with third parties outside the purposes of content filtering. All data transmitted to our servers is encrypted using industry-standard security protocols. Users remain fully in control of what is blocked, and filtering is applied only as specified by the user.
