Calmful Privacy Policy

Effective and last updated: August 14, 2026

This Privacy Policy explains how DeLow Dynamics (“DeLow Dynamics,” “we,” “us,” or “our”) collects, uses, discloses, and protects information when you use the Calmful mobile application, website, and related services (collectively, “Calmful”).

Short version: Calmful uses the information needed to provide your account, daily mindfulness experience, optional reminders, subscriptions, advertising for free users, and optional subscriber text messages. We do not sell personal information for money, and Calmful does not request permission to track you across other companies’ apps or websites.

1. Information We Collect

Information you provide

  • Account information: your name, email address, authentication provider identifier, and profile information when you create or use an account. If you use Sign in with Apple or Google Sign-In, we receive the information that provider makes available based on your choices.
  • Mindfulness information: your selected focus, mood or check-in, daily reflection, completion status, streak, favorites, and mindfulness history that you choose to save.
  • Optional SMS information: for eligible paid subscribers who explicitly enable text delivery, we collect your mobile number, consent record, delivery time, time zone, and message delivery status. Calmful does not use your phone number as an authentication method.
  • Support information: information you include when contacting us.

Information collected through the service

  • Subscription information: product identifier, entitlement status, expiration date, and transaction identifiers supplied by Apple. We do not receive your full payment-card information.
  • App and device information: app version, operating system, language or locale, time zone, notification settings, and technical logs needed to operate, secure, and troubleshoot Calmful.
  • Advertising information: free users may see Google AdMob ads. Calmful forces Google’s limited, non-personalized ad treatment, disables the publisher first-party identifier and ad personalization, and uses Google’s User Messaging Platform where consent or privacy choices are required. Google and its eligible advertising partners may still process limited information such as IP address, coarse location derived from IP, ad interactions, and fraud-prevention signals to deliver and secure ads. Calmful does not display ads to users with an active paid entitlement.
  • Guest information: if you continue without signing in, Calmful stores an app-generated guest identifier and your selected settings and mindfulness data locally and, when available, in Firebase anonymous authentication. When you later sign in, Calmful attempts to merge that guest data into your account.

2. How We Use Information

  • Provide and personalize daily mindfulness messages, guided sessions, audio, history, streaks, and settings.
  • Create and maintain accounts and merge eligible guest information into a signed-in account.
  • Verify monthly or yearly subscription entitlements, restore purchases, remove ads for subscribers, and restrict subscriber-only features.
  • Schedule local app notifications at the time you select and adjust scheduling when your time zone changes.
  • Send an optional mindfulness text message to eligible paid subscribers who separately consent to SMS delivery.
  • Show non-personalized ads to eligible free users and obtain legally required advertising choices.
  • Operate, secure, debug, prevent abuse of, and improve Calmful.
  • Respond to support requests and comply with legal obligations.

3. When We Disclose Information

We disclose information only as reasonably necessary for the purposes described above:

  • Google Firebase: authentication, database, cloud functions, storage, security, and service operations. Calmful does not enable Firebase Analytics.
  • Apple: App Store distribution, Sign in with Apple, subscription purchases, transaction verification, and purchase restoration.
  • Google Sign-In: account authentication when you choose Google.
  • Google AdMob and eligible advertising partners: non-personalized advertising, consent management, measurement, frequency control, security, and fraud prevention for free users.
  • Twilio: delivery and processing of optional subscriber SMS messages, including STOP and HELP requests.
  • OpenAI and ElevenLabs: generation of subscriber mindfulness content or audio when those features are used. We design requests to avoid intentionally sending your name, email address, or phone number to these providers.
  • Legal and safety disclosures: when required by law or reasonably necessary to protect users, Calmful, DeLow Dynamics, or others from fraud, abuse, security threats, or harm.
  • Business transfers: as part of a merger, acquisition, financing, reorganization, or sale of assets, subject to appropriate confidentiality and notice requirements.

We do not sell personal information for money. Calmful does not use your mindfulness entries, phone number, or account information for cross-context behavioral advertising.

4. SMS Privacy and Choices

SMS delivery is optional, available only to eligible paid subscribers, and requires separate in-app consent. Message frequency is generally one mindfulness message per day but may vary. Message and data rates may apply. Reply STOP to cancel or HELP for help. You may also disable SMS in Calmful Settings. Disabling or losing a paid entitlement stops future Calmful scheduling. Consent to receive SMS is not a condition of purchasing a Calmful subscription.

5. Advertising Choices

Calmful uses Google’s User Messaging Platform to request or honor advertising privacy choices where required. Calmful forces Google’s limited, non-personalized ad treatment rather than ads based on your past activity, disables the publisher first-party identifier, and disables ad personalization. Limited ads may still use contextual information and restricted storage or signals for delivery, security, and fraud prevention. You can review applicable privacy choices through the consent interface when available. Paid subscribers do not receive in-app ads while their entitlement is active.

6. Data Retention and Account Deletion

We retain information only for as long as reasonably necessary to provide Calmful, maintain security, resolve disputes, and meet legal obligations. Retention periods vary by data type and provider. Local guest information remains on your device until it is cleared, merged, the app is removed, or app data is reset.

You can initiate deletion of your Calmful account from Settings > Account > Delete Account. Account deletion is intended to remove your Firebase account record and associated Calmful user data, including stored mindfulness history and user-specific generated audio, except information we must retain for legal, fraud-prevention, security, or financial-record obligations. Apple subscription billing is managed separately by Apple; deleting Calmful does not by itself cancel an Apple subscription.

7. Your Privacy Rights

Depending on where you live, you may have rights to access, correct, delete, obtain a copy of, or restrict certain processing of your personal information, and to appeal a denied request. You may exercise available in-app controls or contact us. We may need to verify your identity before completing a request.

8. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information, including authenticated access, encrypted network transport, provider access controls, and server-side verification for paid features. No service can guarantee absolute security.

9. Children

Calmful is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child provided information in violation of this section, please contact us so we can investigate and delete it.

10. International Processing

DeLow Dynamics operates from the United States. Our service providers may process information in the United States and other countries. Where required, appropriate legal safeguards are used for international transfers.

11. Third-Party Policies

Third-party services process information under their own policies. Relevant policies include Google, Google advertising, Apple, Twilio, OpenAI, and ElevenLabs.

12. Changes to This Policy

We may update this Privacy Policy as Calmful changes. We will post the updated policy here and revise the date above. If a change materially affects how we use personal information, we will provide additional notice where required.
