Privacy Policy
What Syllivo is
Syllivo is a text-to-speech studio that runs in your browser. You type or paste a script, choose a voice, and the app generates spoken audio for that script.
On-device processing
Voice generation happens on your device, in your browser. There is no cloud text-to-speech API call for inference: your script text and your generated audio are not sent to a voice-generation server. Voice files are downloaded once from official sources, verified, and stored in your browser's local storage and cache on your device.
What stays on your device
Your projects, your scripts, your reference recordings for Custom Voice, and your generated audio are stored locally in your browser. If you clear your browser storage, locally saved projects and audio can be lost, so export finished audio you want to keep. Generation stops if you close the browser, and the voice model is unloaded from memory after each job.
Analytics, only if configured
Google Analytics is off by default. If the site owner configures a real GA4 measurement ID, analytics loads with IP anonymisation on and sends only generic, non-personal events: page views, generation started or completed, and the generic voice set used (Fast, Quality, or Custom Voice). Your script text, your audio, your voice profile names, and any personal data are never sent to analytics.
Ads, only if approved and configured
Ads are not live in this build. The Remove Ads option is Coming Soon, and there is no purchase flow. If the site owner later configures a real AdSense publisher ID after Google approves the site, ad code will load only on non-intrusive placements (page footers and blog pages, never inside the Studio text editor and never overlaying generation controls). Ads will never receive your text, audio, voice choice details, or any personal data, and ad code does not read Studio state.
What this policy does not cover
This policy describes Syllivo itself. It does not cover third-party sites or services you visit from links in the app or blog, which have their own policies. Voice files are downloaded from official sources; those sources' own terms apply to the files themselves.
