ElevenLabs: If you use voice features, your text messages are sent to ElevenLabs for text-to-speech conversion, and voice recordings are sent for speech-to-text processing. Audio data is processed in real-time and is not permanently stored by ElevenLabs.

Meta (Facebook/Instagram): We use Meta's Conversions API to measure the effectiveness of our advertising campaigns. We send hashed (encrypted) user data such as email and name, along with conversion events (registration, activation, subscription), to Meta for ad attribution and optimization. This data is sent in a privacy-preserving manner using SHA-256 hashing.
