_Personal information_ If you use one of the Premium Voices, you'll be asked to sign in by creating an account, or using your Google, Apple, or Facebook account, and grant Read Aloud access to your basic user profile, which includes name and email address. We require this information for usage tracking, since the Premium Voices requires making a purchase when usage exceeds the monthly free tier. If you don't use the Premium Voices, you don't need to sign in, and no information is collected.
_Browsing history_ We do not track the user's browsing history. We realize the importance of privacy, so we make sure our extensions require only the minimum set of browser permissions to operate. In particular, during installation, it does not ask for the "Read your browsing history" or the "Read and change all your data on the websites you visit" permissions, both of which could be used to track the user's browsing history.
_Text converted to speech_ When you select one of the offline text-to-speech voices, the speech synthesis occurs locally on your computer and is never sent to the internet. And neither the input text nor the synthesized speech are saved or stored on your computer.
When you select one of the non-offline text-to-speech voices, the input text is sent to a cloud provider for synthesis. Each cloud TTS provider has a different privacy policy regulating what they do with the text they receive for synthesis.
When you select the "ReadAloud Generic Voice" or any of the voices in the Premium group, the input text is sent to our cloud server for synthesis. The server may use your anonymized IP address and User-Agent data for purpose of analytics, abuse management, and service improvement. The server may cache the input text, as well as the synthesized speech, for short amounts of time as part of its normal operation; it does not save them to any type of permanent storage.
_Geolocation_ If you select a voice that is synthesized on our server, your anonymized IP address may be used for geolocation for analytics purposes.
_Issue reporting and contact forms_ If you use the in-app report-issue function or use the contact form on our support website, your comments and information may be kept in our support database for a maximum of 6 months.
_Analytics_ The extensions use Firefox Addons Store's built-in analytics. Firefox will collect basic extension usage data, including when the extension is installed, invoked, and uninstalled. The extension may also use its own counters to analyze usage patterns. This information is anonymized and do not present privacy concerns.
