Below you will find a detailed list of domains that are included in each filter category. Remember that categories are blue in the mobile/web application. Specific services are red in the mobile/web application. Only categories will be listed as specific services are generally self-explanatory.

Important Notes

The lists below were generated in March of 2025 and should be considered accurate to that date. Our goal is to update this list every 3 months.  Alta Labs does not claim that these lists are now nor will ever be 100% complete coverage.  Additionally, there are some instances where the filtering is not based 100% on domain names and may contain other heuristic, more nuanced analytics to determine whether a particular site would be blocked or not.

Some of these items act as wildcards. If you do not see what appears to be a valid TLD (top level domain), it simply means that any domain that starts with that text is blocked. For example, under the Data Transfer category, you see `slack-assets2.s3-`, this means that any domain that starts with “slack-assets2.s3-” would be subject to the filter.

This list is open source. Any changes we make to the Alta list will be suggested to be added to the open source list.
