01What you share
You can provide a name or nickname, typed messages and microphone audio. Voice input is optional. These inputs help Kokoro understand your request and create a conversation, meditation script and narration. Your preferences and library are also stored on your device.
02AI processing and your permission
Before you share with AI, the app asks for explicit permission. Microphone permission is a separate choice. With your permission:
- ElevenLabs processes the name, text and voice you share for transcription, voice conversations and spoken audio. Its response models may use OpenAI, Google or Anthropic.
- OpenAI receives text from your request and conversation to write your personalised meditation.
- Railway hosts the Kokoro backend, which processes requests and stores generated session material.
The app uses a sound library for its background music. Earlier versions used Suno to generate meditation audio and offered optional Sign in with Apple. Recordings and local data from those versions may remain in your library after an update.
AI providers process information under their terms and privacy policies. The ElevenLabs conversation configuration has a seven-day retention setting. This setting does not establish the retention period of every downstream model provider. We do not promise zero retention or that all providers exclude your information from model improvement.
03Subscriptions and service protection
Apple handles App Store payments. Kokoro receives signed subscription information, such as product, transaction, expiry and revocation details, to verify Premium. Kokoro does not receive your payment card details.
An installation identifier, verified purchase identifiers and usage counters help prevent misuse and enforce access. The backend stores hashed purchase identifiers and subscription status. Operational diagnostics include request path, status and timing. They exclude spoken words, query text and provider credentials. Hosting providers may also process network information such as your IP address.
04Usage analytics
PostHog usage analytics helps us find problems. From Kokoro 5.0.4 it is on by default, and you can turn it off at any time in You › Usage analytics; earlier versions keep it off until you allow it. Events describe actions such as starting a session, playback progress and purchase outcomes, with installation/session identifiers and app details. The app's analytics event contract excludes your name, conversation, meditation text, audio and payment card details. Turning analytics off stops new analytics events. Operational service diagnostics are separate from this choice.
The iOS app contains no third-party advertising and does not use these analytics events to track you across other companies' apps or websites. We do not sell your personal information.
05Storage and retention
Your device holds preferences, library records and downloaded audio. The backend also retains personal session briefs, scripts, metadata and rendered audio so generated meditations can be delivered and played. This material is not stored only on your phone.
There is currently no general automatic expiry for backend meditation records. We retain them while providing the service, unless removed in response to a deletion request or service cleanup. Subscription and usage records are kept to operate access and prevent misuse. AI providers have their own retention policies. Device backups may retain local copies under your Apple settings.
06Your choices and deletion requests
- AI sharing. Choose Not now at the consent screen, or turn AI data sharing off in You. This stops new AI requests. Saved meditations remain available. It does not recall information already sent to providers.
- Microphone. Revoke microphone permission in iOS Settings. You can use text input instead.
- Analytics. Turn usage analytics off in You to stop new analytics events.
- Start over. This resets the profile and library shown in the app. It is not remote deletion or secure erasure of retained audio, older storage or backups. Uninstalling removes the app's local container; manage backups through Apple.
- Deletion and access requests. Contact dan@aiboostly.com. Include enough information to identify the session or record, such as its title and approximate creation date. We may ask for additional details to locate data in this account-free service. We will explain what we can locate and remove, including any applicable retention requirements.
07Age and security
Kokoro is intended for people aged 16 and over. Requests use encrypted connections. No storage or transmission method guarantees complete security.
