Crierwick: Text to Speech Reader — Privacy Policy (publisher: Zydeno, contact: support@zydeno.com, effective 19 October 2026)

Crierwick reads pages aloud with the voices of your own computer. The extension stores data only in your browser (storage.local); nothing is sent to Zydeno or anyone else. There is no account, no analytics, no advertising and no tracking, and the extension makes no network requests of its own.

Stored in storage.local on your device: your settings (speed, pitch, volume, voice per language, reading filters, theme, interface language, player position), your pronunciation list, and saved places for up to 300 pages (page address without # part and tracking parameters, sentence number, first 80 characters of that sentence, page title). You can export, forget or reset them in Settings, or remove everything by removing the extension.

Pages are read only after you click the toolbar button, a right-click menu item or a keyboard shortcut, and only in that tab. Page text is split into sentences in the tab and handed to your browser's speech service; it is not kept or sent anywhere by Crierwick.

Voices marked "On device" speak on your computer. Voices marked "Online" are offered by some browsers and send each sentence to that voice provider's service; Crierwick hides them until you turn on "Show online voices" and marks them as Online.

Permissions: activeTab (the tab you start it on, after your action only), scripting (puts the reader and player into that tab), contextMenus ("Read from here" and "Read selection"), storage (settings, word list, saved places), tts in Opera only (the browser's speech service with your system voices).
