Consumer Health Data Privacy Notice

Last updated: September 9, 2026

This notice supplements the MystiCall Privacy Policy for consumer health data governed by Washington State’s My Health My Data Act where applicable.

MystiCall is not a medical or healthcare service. However, users may voluntarily discuss personal matters in open-ended conversations that could constitute “consumer health data” under Washington law.

Categories that may be collected

Depending on what a user chooses to discuss, data may include information relating to:

- mental or emotional state;

- sexual or reproductive matters;

- symptoms or health experiences voluntarily mentioned by the user;

- other information Washington law defines as consumer health data;

- inferences generated from such information when necessary to provide the requested conversation.

MystiCall does not require this information to create an account.

Sources

Consumer health data may come directly from:

- the user’s text input;

- the user’s voice input/transcript;

- contextual information the user asks MystiCall to remember.

Purposes

We may use this information only as necessary to:

- provide the interaction requested by the user;

- maintain user-selected personalization/continuity;

- secure/troubleshoot the Service;

- comply with law.

MystiCall does not use this data to provide medical diagnosis or treatment.

Sharing / processors

To provide requested AI features, data may be processed by contracted service providers such as:

- OpenAI;

- ElevenLabs;

- Supabase — account authentication and account records; Railway and its infrastructure providers — application hosting and database;

- email and support providers, if a user chooses to include health-related information in a support request. RevenueCat, Sentry and Expo are not intended to receive the substance of user conversations.

We do not sell consumer health data.

Rights

Where Washington law applies, a consumer may have rights to:

- confirm whether consumer health data is collected/shared/sold;

- access the data;

- withdraw consent where consent is the legal basis;

- request deletion;

- receive information regarding relevant third parties/affiliates;

- appeal a refusal.

Submit requests to:

hello@mysticall.ai

or through the account-deletion/privacy controls available in MystiCall.

We may verify identity as permitted by law.

Changes in collection/use

We will not collect, use or share additional categories of consumer health data for a materially new purpose requiring consent without providing the required disclosure/consent first.
