Third-Party Services

Lang Forge connects to the following third-party services. Basic translation, the language switcher, string translation, and hreflang work fully offline with no external calls — data is sent only when you use an AI feature.

• Avakode API (https://avakode.com) — powers AI translation and AI quality checks, and validates your license. When you run an AI translation or QA check, the source post content, the target language, your site URL, and your license key are sent. The Avakode API routes AI requests to OpenAI and/or DeepL on your behalf. Terms: https://avakode.com/terms — Privacy: https://avakode.com/privacy
• OpenAI (used by the Avakode API to perform AI translation) — Terms: https://openai.com/policies/terms-of-use — Privacy: https://openai.com/policies/privacy-policy
• DeepL (used by the Avakode API to perform AI translation) — Terms: https://www.deepl.com/en/pro-license — Privacy: https://www.deepl.com/en/privacy
• Anonymous usage analytics (opt-in, OFF by default) — Only if you explicitly opt in from the Lang Forge settings, the plugin sends anonymous product-usage telemetry to the Avakode API (https://avakode.com/telemetry): a random install ID (UUID, not tied to your site URL or any account), your bucketed WordPress and PHP version ranges, the plugin version, and aggregate feature-usage event counters. It is sent ONLY after you opt in and can be disabled at any time. It never sends your site URL, email address, post or form content, or license key. Privacy: https://avakode.com/privacy
