Privacy Policy

Last updated: September 7, 2026

trisaveurs ("we", "us") sets out below its Privacy Policy (this "Policy") concerning how we handle users' personal information in "Exevoice" (the "Service") that we provide.

Article 1 (Personal information)

"Personal information" means personal information as defined in the Act on the Protection of Personal Information: information about a living individual that can identify that specific individual by the name, date of birth, address, telephone number, contact details or other description contained in it, together with information that can identify a specific individual on its own (personal identification codes), such as data on facial appearance, fingerprints and voiceprints, and the insurer number on a health insurance card.

Article 2 (Information we collect and how we collect it)

In providing the Service, we collect the following information.

Information stored on our servers

Information collected automatically as you use the Service

Information we do not store on our servers

The Service does not store on our servers the audio you record, or the transcribed text before notation correction. These are sent temporarily to outside AI processing services and are discarded once processing finishes. See Article 4 for details.

The Service records what you choose to say, and what you say may include references to bodily sensations or how you are feeling physically. We do not actively collect or analyse these as information for medical or health management purposes; we treat them as part of your own journal for looking back.

Article 3 (Purposes for collecting and using personal information)

We collect and use personal information for the following purposes.

Article 4 (Handling of audio data and what you say)

Prior consent to sending data to outside AI services

Before sending your data to the outside AI services described below, we disclose in a screen inside the app the types of data sent, the names of the companies they are sent to, and the purpose of sending, and we obtain your consent.

If you do not consent, no recording or transcription takes place and no data is sent to outside AI services at all. Even then, you can still read the session records already stored, as before.

You can review what was disclosed at any time from "About AI processing" in the app's settings screen. The record of consent (the date and time, and the version of the disclosure) is stored on our servers.

Audio and pre-correction text are not stored

The Service does not store on our servers the audio you record or the transcribed text before notation correction. They are processed as follows.

1. The recorded audio is sent through our servers to OpenAI's Whisper API, which produces transcribed text. The audio is never stored on our servers.
2. The transcribed text is corrected for notation using a dictionary we maintain, then sent to Anthropic's Claude API, where it is organized into structured text (the "session record"): summary, your words, physical, memory, share text and so on.
3. Once the session record has been generated, the audio and the transcribed text before notation correction are discarded.

Storage of session records and full transcripts

Session records are stored in the Asia Pacific (Tokyo) region of Supabase, in a form that only you can read.

The full transcript after notation correction is stored in the same region, linked to your account. This full transcript is not shown in the app screens and is used only as an internal reference when generating features that look back and observe across your accumulated records. We do not actively read or analyse individual content.

About training use at outside AI services

When we use the OpenAI and Anthropic APIs, we send your input with settings that exclude it from training their machine learning models. Please refer to each company's API usage policies for details.

About references to your body and physical condition

What you choose to say may include descriptions of your body: its state, sensations, discomfort and so on. We state the following about such descriptions.

About the share feature

If you choose to publish content to an outside service (such as X) using the share feature, that content becomes public information and is handled in accordance with the privacy policy of that outside service. Managing or deleting it after sharing is your own responsibility.

Article 5 (Outside services and transfer of information overseas)
