Privacy Policy
EchoCard Notes is designed for private voice-first note capture and AI-assisted organization. This policy explains what data the app handles and how it is used.
Data you create
EchoCard Notes lets you record voice notes, create transcripts, generate Echo Cards, and save action items. Audio recordings are stored locally in the app's protected storage on your device and are excluded from device backups.
On-device transcription
EchoCard Notes uses the bundled SenseVoiceSmall model to transcribe recordings on device. Raw audio is not uploaded for transcription.
AI synthesis
When you ask EchoCard Notes to generate Echo Cards, the app sends transcript text and source metadata through EchoCard's synthesis service to an AI provider. This may include source identifiers, timestamps, and relevant source excerpts so the app can create summaries, suggested actions, and reusable prompts.
Raw audio files are not sent for AI synthesis.
Tracking and advertising
EchoCard Notes does not sell your data. EchoCard Notes does not use your data for third-party advertising or tracking across apps and websites.
Data retention and deletion
Local recordings, transcripts, cards, plans, and prompts remain on your device unless you delete them or remove the app. Support requests are retained only as long as needed to respond, troubleshoot, and meet reasonable operational or legal requirements.

隐私政策摘要
EchoCard Notes 会将录音保存在设备本地受保护的应用存储中，并排除在设备备份之外。应用使用内置的 SenseVoiceSmall 模型在设备端转写录音，不会为了转写上传原始音频。
当你主动生成 Echo Cards 时，应用会通过 EchoCard 的整理服务发送文字稿和来源元数据，用于生成摘要、建议行动和可复用提示词。原始音频不会用于 AI 整理上传。
EchoCard Notes 不出售你的数据，也不会将你的数据用于第三方广告或跨应用、跨网站追踪。
