Privacy Policy
Mind Lab · Effective November 11, 2026
Mind Lab is a self-hypnosis and guided audio app for iPhone and Apple Watch. This policy explains what we collect, why, who helps us run the app, and the choices you have. We don't sell your data and we don't show ads. We only use your device's advertising identifier if you allow it (see “Advertising attribution”).
What we collect
| Data | Why we use it |
|---|---|
| Account details: the account ID, email and name Apple shares when you use Sign in with Apple. With Apple's “Hide My Email”, we only see a relay address. | To create your account, keep your plan and progress across devices, and contact you about your account. |
| Your answers: onboarding quiz answers, your goal, the name you want sessions to use, and your check-in answers and notes. | To write and personalize your sessions and plan. |
| Voice recording (only if you choose to set up affirmations in your own voice). | To make audio of your affirmations in your voice. See “Your voice” below. |
| Purchases: your subscription status and transaction details from the App Store. We never see your card details. | To unlock Mind Lab Plus and restore purchases. |
| Usage: in-app events such as sessions started and finished, screens viewed and features used, linked to your account ID. | To understand what works and improve the app. Free text you type or speak is never sent to analytics. |
| Diagnostics: crash reports and performance data, such as device model, iOS version and the code that failed. | To find and fix bugs. |
| Device token for notifications, if you turn them on. | To send reminders and tell you when a session is ready. |
Speaking your answers
When you speak an answer instead of typing it, speech is turned into text on your iPhone using Apple's on-device speech recognition. The audio isn't sent to us. Only the resulting text is saved, like a typed answer.
Your voice
If you record yourself to hear affirmations in your own voice, we ask for your consent first. Your recording is stored encrypted. To make the audio, it's sent to our voice provider (ElevenLabs), which creates a temporary voice model, speaks your affirmations, and then deletes the model straight away. You can delete your recording and all audio made from it at any time in the app. Deleting your account deletes it too.
Advertising attribution
We advertise Mind Lab on other platforms. To learn which ads lead people to install and subscribe, our subscription provider Adapty matches app installs and purchases to ad clicks. If you allow tracking when iOS asks, this includes your device's advertising identifier (IDFA). If you don't, nothing about tracking is shared, and the app works exactly the same. You can change this any time in Settings → Privacy & Security → Tracking.
Apple Health
With your permission, Mind Lab can save your sessions to Apple Health as Mindful Minutes and State of Mind entries, and read your sleep analysis to show how sessions relate to your sleep. Health data stays on your device and in Apple Health. We don't send it to our servers, use it for advertising or marketing, or share it with anyone. You can change these permissions at any time in the Health app.
Who helps us run Mind Lab
We share data only with the service providers that run parts of the app for us, and only what each one needs:
- Supabase: hosts our database, sign-in and servers.
- Anthropic: writes your session scripts from your answers. Anthropic doesn't use this data to train its models.
- ElevenLabs: turns scripts and your name into spoken audio, and, if you use it, your own-voice affirmations.
- Cloudflare: stores generated audio files.
- Adapty and Apple: process and verify subscriptions; Adapty also measures which ads led to an install or purchase.
- Mixpanel: product analytics (usage events).
- Sentry: crash and error reports.
We may also disclose information if the law requires it, or to protect the rights and safety of our users. If Mind Lab is ever sold or merged, this policy would continue to apply to your data.
How long we keep it
We keep your data while you have an account. When you delete your account, we delete your profile, answers, plans, generated audio and voice recording from our systems. Some records may stay for a limited time in backups, in logs, or where the law requires us to keep them (for example purchase records).
Your choices and rights
- Delete your account at any time in the app under Profile → Delete Account.
- Turn permissions on or off (microphone, notifications, Apple Health) in iOS Settings.
- Access or correct your data, or ask us any privacy question, by emailing us (below).
Depending on where you live (for example the EU, UK or California), you may have rights to access, correct, delete or move your data, or to object to some uses of it. We honor these requests wherever you live. Contact us and we'll reply within 30 days. If you're in the EU or UK, you can also complain to your local data protection authority.
Security
Data is encrypted in transit, and voice recordings are also encrypted at rest. Access to our systems is limited to what's needed to run the app. No system is perfectly secure, but we work to protect your information.
Children
Mind Lab isn't intended for children under 13 (or under 16 in the EU and UK), and we don't knowingly collect their data. If you think a child has given us information, contact us and we'll delete it.
Not medical advice
Mind Lab is for relaxation and personal development. It isn't a medical service and doesn't diagnose or treat any condition.
Changes to this policy
If we make important changes, we'll update the date above and let you know in the app.
