Bir Söz Privacy Policy

Last updated: June 19, 2026

Bir Söz is a Chrome extension for learning Kazakh words while browsing. Its mission is to help create a lightweight Kazakh-language environment during everyday web use. This policy explains what data the extension handles and how it is used.

Data Stored Locally

Bir Söz stores the following data in chrome.storage.local on the user's device:

• selected vocabulary and custom vocabulary entries;
• word learning progress, including repetition schedule and review history;
• challenge counts, correctness, response time, streaks, and settings;
• extension preferences such as cooldown, quiet mode, and analytics preference.

This local data is used to show vocabulary prompts, schedule reviews, and show progress inside the extension.

Usage Analytics

Usage analytics are disabled by default. On first install, Bir Söz shows a disclosure screen with an opt-in action. Analytics can also be turned on or off at any time in the dashboard settings under "Usage statistics".

When analytics are enabled, Bir Söz sends learning-related technical events to https://api.lukivan8.com. The data may include:

• a randomly generated installation identifier;
• built-in vocabulary IDs, built-in vocabulary names, built-in word IDs, and built-in word text used by the learning feature;
• whether a challenge was answered, skipped, enabled, or disabled;
• whether an answer was correct;
• response time;
• spaced-repetition progress such as repetition count, interval, next review time, and mastery state;
• aggregate custom vocabulary progress counts, if the user creates custom vocabulary.

Analytics requests are limited to two types: learning events and daily learning-progress snapshots. Learning events record actions such as answers, skips, correctness, response time, and enable/disable events. Daily snapshots record built-in word progress and aggregate vocabulary progress.

Bir Söz does not send visited page URLs, page content, browsing history, cookies, passwords, form inputs, screenshots, advertising identifiers, Google account IDs, email addresses, or device hardware identifiers. The extension also does not include clicked link URLs, link text, or selectors in analytics events. Bir Söz does not send custom vocabulary names, custom word text, custom word IDs, or custom per-word progress.

Analytics are used only to understand whether the learning prompts support Kazakh vocabulary practice and to improve the learning experience.

Data Sharing

Analytics data is sent only to the developer-operated API at https://api.lukivan8.com. Bir Söz does not sell user data and does not share user data with advertisers, data brokers, or advertising platforms.

Data Retention and Deletion

Local learning progress, custom vocabulary, and settings remain on the user's device in chrome.storage.local. The user can remove this local data by uninstalling the extension or clearing extension data.

When usage analytics are enabled, analytics are associated with a random installation identifier. They are not associated with a Google account, email address, advertising identifier, or device hardware identifier.

Permissions

Bir Söz requests Chrome permissions to:

• store local settings and learning progress;
• detect generic tab/navigation activity so vocabulary prompts can appear during normal browsing;
• run scheduled background maintenance for queued analytics;
• communicate with https://api.lukivan8.com for usage analytics when usage statistics are enabled.

Limited Use Statement

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
