Scope of this policy
This policy applies only to the Söz Chrome extension. It does not replace the separate Privacy Policy for the Söz mobile app, its widgets, or the getsoz.com website.
The extension works without registration or a Söz account. It does not create an advertising profile or use a persistent identifier to recognize you across websites.
Information stored in your browser
The extension stores only the information needed to remember your preferences and schedule learning. It uses chrome.storage.local, which belongs to the extension in your Chrome profile.
- Extension settings, including whether it is enabled, exercise frequency, daily limit, interface language, and whether skipping is allowed.
- Learning progress, including completed and correct answer counts, streak, per-word review state, ease, next review date, and lapse count.
- A counter of videos started since the previous exercise and a short-lived random tab token used to prevent two YouTube tabs from showing a card at the same time.
How YouTube pages are processed
On youtube.com, the extension checks whether the current page is a standard watch page and locates the main video player so it can pause playback, show an exercise, and resume after the exercise. It also checks whether playback is an advertisement, a live stream, or fullscreen so it can avoid interrupting at the wrong time.
A YouTube video ID may be held briefly in the tab memory to count a distinct video once. It is not written to storage, sent to Söz, or used to build watch history. The extension does not collect video titles, channel names, subtitles, audio, video content, or your YouTube account information.
Network requests and sharing
Exercises, word data, brand assets, settings, and scheduling logic are packaged with the extension. The extension does not send learning progress to a Söz server and contains no advertising SDK, third-party tracker, or server-side analytics provider.
The extension opens getsoz.com only after you click a Söz link. That link includes UTM parameters identifying the extension and the placement you clicked, but it does not contain your answers, progress, video information, or a user identifier. Once the website opens, the separate website and app Privacy Policy applies to that visit.
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Chrome permissions
- Storage: saves settings and learning progress locally in the browser.
- Access to https://www.youtube.com/*: finds and controls the main player and displays the exercise card on YouTube. No other website receives a content script.
Optional local debug events
Developer debug events are off by default and are not exposed as normal analytics. If debug mode is explicitly enabled in the extension’s local state, the extension may keep up to 200 interface events in chrome.storage.local, such as an exercise being shown, answered, or skipped. These events remain on the device and do not include a YouTube URL, title, or video ID.
Your controls and data deletion
You can disable YouTube exercises or reset learning progress from the extension settings. Removing the extension from Chrome deletes its local extension storage, including settings and locally stored debug events. Söz cannot remotely identify or delete browser-only data because the extension has no account or backend sync.
Changes and contact
We may update this policy if the extension’s permissions, storage, or data flows change. The effective date above will be updated. Questions about extension privacy can be sent to [email protected] with “Chrome extension privacy” in the subject.
