What data is processed
Kukuluku does not operate its own processing servers and does not require an account. During use, the following is sent directly to third-party providers:
- Selected text — sent to Google Translate and, if enabled, to your chosen AI provider.
- Target language — sent as part of translation requests.
- Translation provider — Google Translate is used for core translations.
- AI provider — optional explanations via Claude, GPT, Gemini, or Grok.
When translation or AI explanation is requested, selected text is processed under the third-party provider's own policy. Kukuluku does not control third-party retention or downstream processing.
API keys
API keys are stored locally on your device only using chrome.storage.local.
Keys are not sent to Kukuluku infrastructure.
Recent translation history
Kukuluku can store recent translations locally in your browser so you can review or copy them from the extension popup.
This history may include the selected text, the translated text, source language, target language, and timestamp.
Recent translation history is stored using chrome.storage.local. It is not sent to Kukuluku servers and can be cleared from the extension settings.
Local usage counters
Kukuluku stores local counters, for example translation count and active days, to decide when to show optional rating or support prompts.
These counters contain no personal identifiers and stay on your device.
No analytics, no ads, no sale
Kukuluku does not include analytics trackers or ad SDKs and does not sell user data.
Kukuluku uses user data only to provide and improve selected-text translation and optional AI explanations, and complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
