Semek — Privacy Policy

Last updated: 22 October 2026

Semek is a Chrome extension. This policy explains what data it handles.

What Semek does with your data

Keyboard-layout detection (Hebrew/English). Runs entirely on your device. Semek looks at text as you type in order to spot a word typed in the wrong language and suggest a correction. That text is never stored, logged, or sent anywhere. Password fields are never read; Semek only checks whether one contains Hebrew characters and never sees or keeps the value.

AI text polish (optional, only when you ask). Nothing is sent anywhere until you click the sparkle icon or press the polish shortcut. Then:

• If your browser supports Chrome's built-in on-device AI (Gemini Nano), the text is processed locally and never leaves your computer.
• Otherwise, if you have entered your own API key, the selected text is sent to the provider you chose (Anthropic, OpenAI, or Groq) to be rewritten, and is governed by that provider's terms and privacy policy. Semek does not operate any server and never receives your text.
• The AI polish icon is disabled on Gmail.

PDF text & signature editor. PDFs are opened, edited, and saved entirely in your browser. Files are not uploaded to Semek or anyone else. For Google Drive previews, the file is fetched from Google using your existing signed-in session, only when you click "Edit / Sign PDF".

What Semek stores

Stored in your browser only (Chrome extension storage):

• Your on/off settings (synced through your Chrome account if sync is on).
• Your AI provider choice and API key (local only; not synced).
• Your saved signatures and the position of the PDF button (local only).

Semek has no accounts, no analytics, no advertising, and no remote servers. It does not sell or share user data, and does not use data for purposes unrelated to the features described above.

Permissions

Semek asks for access to all websites because it must watch the text boxes you type in and detect PDF pages on any site. See the store listing for the justification for each permission.
