HappyHack Inc. handles user information in providing JotVoice as follows.

Information we collect and how we use it

  • When you sign in with Google or Apple, we verify the ID token we receive and identify you by its issuer and account identifier. We use Google account data to sign you in, to match you to your account and to confirm connections you have allowed.
  • We use your app settings, the identifiers, public keys and push tokens of the devices you register, and the connections you allow to decide where notifications are sent and how they are shown.
  • Notifications from AI services you have allowed to connect may include a title, body, read-aloud text and links. We use these to deliver them to the target device and to show and play them on it.
  • We use delivery records that contain no content, and operational records such as errors and processing results, for resending, syncing, preventing misuse and investigating failures.

Storage and deletion

Notification content that a device has not yet retrieved is stored encrypted with that device's public key. It is deleted when the device finishes retrieving it, or when the storage time set by the user ends. The default is 1 hour. Received notification content is kept in the history on the device and deleted 30 days after receipt.

If you choose to delete your account in the app settings and verify your identity, we revoke the access of your devices and connections and delete your account data on the server. Local data on the device is deleted by the app. Anything left on the device can also be erased by deleting the app.

Data sent to external services

We use Google and Apple for authentication, Microsoft Azure for cloud operation and notification delivery, and Apple Push Notification service and Firebase Cloud Messaging for push delivery to devices. For push delivery, we send the delivery providers the information needed to identify the destination and receive the notification. To AI services you have allowed to connect, we return the results and delivery status of notifications within the scope you allowed.

Information obtained from Google is not used for advertising or sold. We provide it to third parties only for processing needed to provide the service and where required by law.

If you use custom voices, we use Google Cloud's Gemini TTS to create voices and to synthesize notification sounds. We send Google the voice instructions, the target language, a fixed sample text, the short text to turn into a notification sound, and the minimum settings needed for synthesis. We do not send the notification body, the read-aloud text shown after opening, or device or account identifiers. Google stores the created voice and its instructions for up to 365 days after it was last used, or until the voice is deleted.

Information passed to connected AI services or to the external services above is handled under each service's own privacy policy and terms. For information outside JotVoice's control, please check each service's notices.
