2. Services that are not sub-processors

Open data sources. To build source graphs, our service requests public content from the Reddit API, the YouTube Data API, Wikipedia and Wikidata, RSS and news feeds, and publicly accessible websites. These requests may contain the name of a campaign's subject, but these services do not process Customer Data on our behalf and are not sub-processors.

Website fonts. Our website loads fonts from Google Fonts (Google, USA). When a page loads, your browser sends your IP address and browser information to Google. No cookies are set for this purpose.

3. Changes to this list

We give at least 30 days' notice before a new or replacement sub-processor starts processing Customer Personal Data: we update this page and inform the owners of each customer Organization by e-mail or in the Service. Customers can object as described in Section 6 of the DPA. Anyone else who wants to be notified of changes can write to privacy@tonecast.io.
