Privacy policy

1. Scope and developer

This policy covers the DSay iPhone and Apple Watch apps and www.dsay.ai. The operator is an independent developer. The public contact address is yand@dsay.ai. Third-party services you choose also process information under their own privacy policies.

2. Recordings, text, and memories

You actively start and stop everyday recording on Apple Watch. Your paired iPhone can receive recordings, import audio, and transcribe and organize it locally. Audio, time marks, transcripts, summaries, actions, memories, and reflections are primarily kept in private app storage on your devices. DSay does not provide a developer-hosted recording database or require a DSay account.

Optional owner-voice enrollment records a short sample on iPhone and computes voice features locally to assist speaker labeling. You can delete this profile. It is not used for identity authentication. Content that you export or share is handled by the receiving person or app you choose.

3. Local processing and optional external AI

Default transcription and speaker processing run on-device. Some local AI features require supported hardware, system models, or downloaded resources. Model hosts receive the ordinary network requests needed to download those resources.

External AI is initially disabled. When you enable and configure it, the question, selected transcript excerpts, relevant memories, or action context needed for a request are sent directly from your device to your chosen endpoint. Original recordings are not attached to these AI requests. Your API key is also sent to the endpoint you configure. Check that it is trustworthy and review its terms, fees, and retention settings.

Per-request confirmation before sending to external AI is an optional setting and is off by default. You can enable it, disable external AI, or remove the API key in Settings. Information already received by a provider is subject to its policies; deleting a local copy does not automatically delete a provider’s copy.

4. Permissions, location, and health

DSay accesses system capabilities through the relevant permissions. Microphone access supports recording you initiate and optional voice enrollment; notifications support action reminders. You can change permissions in system settings. Withdrawing permission may affect the associated feature but does not automatically delete earlier content.

With location permission, recordings can include locations at their start, during capture, or at their end. Recording-boundary location capture is enabled by default, subject to system permission. Optional scene assistance can collect location and motion observations during recording to help distinguish segments. Place-name lookup may send coordinates to Apple Maps.

Health access is optional and read-only. It adds heart-rate and workout context you authorize to recording reviews. DSay does not write HealthKit records. This sensor context is composed locally and is not sent to AI writing services. It is not continuous health monitoring, diagnosis, or authentication data.

5. Device protection and diagnostics

App content uses system file protection. API keys and app-passcode verification information are stored in the device Keychain. Face ID verification is performed by the operating system; DSay does not receive or store your facial biometric template. Protect your device passcode and system account as well.

Size-limited rotating diagnostics stay on-device to help diagnose connection issues. They contain sync states, counts, and error codes, not original audio, transcripts, titles, or file paths. The current version does not integrate advertising, cross-app tracking, or third-party behavioral analytics SDKs.

6. Retention, export, and deletion

Local content remains until you delete it, clear device content, or uninstall the app. The main recording-content directory is excluded from system backup. DSay does not promise cloud recovery; export important audio and text yourself. Some system Keychain items may remain after uninstalling, so remove API keys and other credentials in the app before removal.

Deleting a complete recording removes its associated audio, transcripts, summaries, and actions, invalidates related generated content, and disables linked memories. Audio-only deletion retains text and related records. Deleting a Watch copy does not remove an already-synced iPhone copy. Voice profiles, independent memories, and exported copies are managed through their respective controls or storage locations.

7. Website and contact email

The website is a static site hosted on Google Cloud and does not accept uploads of app recordings. The server may log IP addresses, access times, requested paths, response status, browser identifiers, and referring pages for content delivery, troubleshooting, and maintenance. Logs are rotated and cleared according to operational configuration. The server may be in a different region from you.

The website does not use advertising, analytics trackers, or non-essential cookies. Language selection is represented by Chinese and English page URLs, not a server account. Your browser may cache static website resources for performance.

If you email the developer, the developer receives your email address, message, and any attachments you choose to provide. These are handled to respond, troubleshoot, and keep necessary records. Please provide only information needed to address your question.

8. Your choices and contact

You can manage permissions, choose local or external AI, remove API keys, delete voice profiles, manage recordings and memories, and export content. The developer cannot remotely access or delete information that exists only on your devices.

For requests about contact correspondence or website information held by the developer, including access, correction, or deletion, email yand@dsay.ai. The developer will respond based on information that can be identified and applicable law. Material policy changes will be reflected by an updated date and explanation on the website.
